NAE Celebrates Asian American and Pacific Islander Heritage Month

In honor of Asian American and Pacific Islander Heritage Month, we are recognizing the first 20 Asian American men and women (10 in each category) elected to the National Academy of Engineering. They distinguished themselves in business and academic management, in technical positions, as university faculty, and as leaders in government and private engineering organizations. In addition to their pioneering technical contributions, they are models of integrity, diligence, and academic rigor. By their example and through their active mentoring, they have opened the path for success for many others. We are pleased to celebrate them.


Ven T. ChowVen Te Chow (1919-81)
NAE election: 1973; citation: “Developments in hydrological analysis, stochastic hydrology, water resources systems analysis, and watershed hydraulics.”

A noted professor of civil and hydrosystems engi¬neering at the University of Illinois at Urbana-Champaign, Ven Te Chow was recognized throughout the world for his contributions to the science of hydrology and to water resources development.

Born in Hangchow, China, on October 7, 1919, he received his BS degree in civil engineering from the National Chiao Tung University in 1940, his MS degree in engi¬neering mechanics from Pennsylvania State University in 1948, and his PhD in hydraulic engineering from the University of Illinois in 1950. He joined the faculty of the UIUC Department of Civil Engineering in 1948 and became a naturalized US citizen in 1962.

Chow's noteworthy contributions include his watershed experimentation system, which produced storms in the laboratory using sophisticated electronic, pneumatic, and sonar controls. The instrument attracted worldwide attention and interest among scientists, engineers, and the public. It was featured in the March 1969 issue of Public Works magazine and was even the subject of an article in Life magazine (June 6, 1969).

With this unique instrumentation, Chow introduced a new field known as watershed hydraulics. He also developed a formula for hydrologic frequency drainage design, a method of backwater curve computation, and widely used theoretical approaches in stochastic hydrology and water resources systems analysis.

He was a consultant and lecturer to governmental, university, and private organi¬zations around the world, and author of several well-known books, including the popular Handbook of Applied Hydrology and Open-Channel Hydraulics, and more than 200 other technical publications. He was also a founder and first president of the International Water Resources Association, president of the American Geophysical Union’s Section of Hydrology, and a founder of and delegate to the Universities Council on Water Resources.

Chow received numerous awards and honors in recognition of his considerable achievements. In addition to the NAE, he was elected a member of the American Academy of Arts and Sciences and the Academia Sinica; fellow of the American Association for the Advancement of Science and American Academy of Mechanics; and diplomate of the American Academy of Environmental Engineers. He received the Epstein Award, the American Society of Civil Engineers Research Prize, and the Achievement Award of the Chinese Institute of Engineers. He was a National Science Foundation Distinguished Scholar and an honorary mem¬ber of the Asociación Mexicana de Hidráulica.


Rustum RoyRustum Roy (1924–2010)
NAE election: 1973; citation: “Contributions to the development of the modern science and technology of non-metallic materials.”

Rustum Roy was not only one of the world’s leading materials scientists but also a major moving force in national and international science policy and in constructive interactions in science, technology, and religion. A strong advocate of interdisciplinary and integrative learning, he was a brilliant teacher and an inspiration to many seeking change to benefit humanity.

He was born in Ranchi Bihar province in India on July 3, 1924. The family was very well connected, and an early meeting with Mahatma Gandhi left a deep and lasting influence on Roy, spurring his lifelong dedication to molding scientific endeavor to benefit the needs of society.

He took a Cambridge School Certificate from Saint Paul’s School Darjeeling, then a bachelor’s (with honors) and master’s in chemistry at Patna University in 1944, followed by a PhD in ceramic science from Pennsylvania State University in 1948. He joined the Penn State faculty as a research associate in 1950 and by 1957 was a full professor of geochemistry. In 1962 he founded the Materials Research Laboratory at Penn State, the first in the country without block grant support. In 1981 he was named an Evan Pugh Professor, the highest academic title the university can bestow.

Roy was a major innovator in new materials synthesis techniques. Starting in 1948 he devised what is now called the sol-gel process for making pure nanoscale reactive powders for many important ceramic compositions. Originally devised for making ultrahomogeneous materials, the process was shown to be adaptable to making maximally heterogeneous nanocomposites with exciting properties.

A second major area, developed with his colleague O.F. Tuttle, was hydrothermal processing for materials synthesis and crystal growth. Roy focused on materials applications and Tuttle on geological applications.

A third area of immense practical importance was microwave electromagnetic processing. For the first time, using single-mode cavities Roy’s group clearly demonstrated the amazing differences generated by pure E and H microwave fields, with major consequences for proper theoretical understanding.

Roy probably holds the unofficial record for the synthesis of more new ceramic materials than anyone else. He trained and “exported” several generations of students with outstanding crystal chemical backgrounds, and his class notes, never published, have been reproduced and used worldwide.

Although a practicing scientist for 65 years, Roy’s life work defied any professional label: he was dedicated to breaking artificial boundaries in order to integrate science, religion, education, health, art, and social action for human benefit.


Fujio MatsudaFujio Matsuda (1924–2020)
NAE election: 1974; citation: “Leadership in the development and operation of a state-wide transportation system.”

Fujio Matsuda was born October 18, 1924, in Honolulu to parents who had emigrated from Yamaguchi Prefecture in Japan. He grew up in Kaka Ľako and remained proud of his roots there.

He began studies at the University of Hawai'i (UH) in 1942, but in response to the attack on Pearl Harbor enlisted in the 442nd Regimental Combat Team of the US Army. Eventually, he was assigned to the 291st Field Artillery Observation Battalion and shipped to France and northern Germany. Staff Sargent Matsuda was awarded the Bronze Star, and later said his experiences in the war solidified core values about human relationships that guided him through life.

After his tour of duty he earned a bachelor’s degree in civil engineering from Rose Polytechnic Institute in Terre Haute, Indiana, under the GI Bill. He and his wife relocated to Cambridge, Massachusetts, where he earned a PhD in structural engineering from the Massachusetts Institute of Technology in 1952 and continued as a research engineer. After a 2-year research position at the University of Illinois, the family returned to Honolulu in late 1955. From 1956 to 1962, through Hawai'i’s transition to statehood, Matsuda cofounded the civil engineering firm SMS Engineers and became a professor of civil engineering at the University of Hawai'i, eventually serving as department chair.

In 1962 Governor John A. Burns asked Matsuda, at age 38, to serve as director of the State Department of Transportation. During his decade in that position, he directed a large expansion of state highways, airports, and harbors.

In 1973 UH President Harlan Cleveland asked Matsuda to return to the university as vice president of business affairs. In 1974, after Cleveland’s resignation, the board of regents appointed Matsuda the ninth president of the university. He was the first and only UH president of Asian descent and the first Asian-American president of a major US university. Under his leadership, the first systemwide strategic plan was developed, and the East-West Center was separated from the university.

Matsuda left UH in 1984 to become executive director of the Research Corporation of the University of Hawai'i, a position in which he served until 1994. He finally retired in 1996, after 2 years as president of the Japan America Institute of Management Science, and went on to serve on the boards of several nonprofit organizations, including for the Japanese Cultural Center of Hawaii. In 2004 he was honored as a Living Treasure of Hawai'i


Ernest Shiu-Jen KuhErnest Shiu-Jen Kuh (1928–2015)
NAE election: 1975; citation: “Contributions to circuit and system theory.”

Ernest Shiu-Jen Kuh joined the faculty of the University of California–Berkeley College of Engineering in 1956 and made pioneering contributions in active and passive circuit theory, electronic design automation of integrated circuits, and engineering education. He was chair of the Department of Electrical Engineering and Computer Sciences (1968–72) and then dean of the College of Engineering (1973–80). At the time of his retirement in 1992 he held the William S. Floyd Jr. Distinguished Chair.

He was born October 2, 1928, in Beijing. With the political instability in the region prior to World War II, the family moved frequently, eventually to Shanghai in 1937. In 1947 Kuh left China, on a slow ocean freighter, to continue his education in the United States. He received his BS from the University of Michigan in 1949 and the next year, at MIT, his master’s degree, both in electrical engineering. At MIT he met circuit theorist Charles Desoer and the two became frequent collaborators.

He earned a PhD in network theory at Stanford in 1952 and saw his thesis published in the Journal of Applied Physics.

He promptly went to work for Bell Laboratories in Murray Hill, New Jersey. He was the second Chinese employee there. He worked in the transmission development division on issues related to telephone infrastructure, specifically transmission repeater designs and submarine cable design. His work was incorporated in the first transatlantic telephone cable, laid in 1956.

By 1966, now at UC Berkeley, Kuh was working with Desoer on what became a widely used book, Basic Circuit Theory (McGraw-Hill), when he was asked to head the Electrical Engineering Department, which had recently integrated computer science. In 1968 he was appointed chair of the EECS Department, which under his leadership explored new domains of research, including bioelectronics, paving the way for the future bioengineering department.

While on sabbatical in Japan in 1977–78, Kuh took up the emerging field of electronic design automation (EDA) and in 1980 decided to step down from the dean’s position to focus on EDA research. His work laid the intellectual foundations for computer-aided design (CAD) and computer-aided manufacturing (CAM).

He authored or coauthored six textbooks and several hundred research papers, and delivered countless technical talks and presentations.

Throughout his academic career, Kuh worked to recruit and retain more women and people of color in the engineering program, and mentored several generations of graduate students. In total he supervised 40 PhD students, who today occupy leadership positions in academia and industry. He and his wife Bettine endowed the Ernest S. Kuh Distinguished Lecture Series to bring notable scientists and engineers to the UCB campus.

He was also a sought-after advisor and consultant for numerous companies and organizations. He held leadership positions on committees for the Institute of Electrical and Electronics Engineers (IEEE), National Institute of Standards and Technology, and National Science Foundation Advisory Committee. For an NRC study on engineering research, he served on the Panel on Information, Communications, Computation, & Control Systems Research (1984–85) and he was a member of the Committee on Scholarly Communication with the People's Republic of China (1979–81).

His impact on engineering education and the field of electrical engineering was recognized through awards including the 1996 C&C Prize of the Japan Society for Promotion of Communication and Computers, the 1998 Phil Kaufman Award given by the Electronic Design Automation Consortium, and the IEEE Centennial and Millennium Medals


Thomas H. LeeThomas H. Lee (1923–2001)
NAE election: 1975; citation: “Leadership in better understanding and the advancement of high power switching devices through physics and engineering.”

Thomas Lee was a founder of the Center for Quality Management (CQM), a professor at MIT, and a pioneer in developing modern management techniques.

He earned his bachelor’s degree in mechanical engineering in 1946 from Chiao Tung University in Taiwan. He was getting training in the United States when political unrest began in China. He and his wife chose to remain in the United States, and, since Lee had worked at General Electric Co. in his native Shanghai, he continued working for the company for the next 30 years. During that time he earned an MS in electrical engineering from Union College in 1950 and a PhD from Renssalaer Polytechnic Institute in 1954.

In 1979 he was hired at MIT as a visiting research scientist and the following year joined the electrical engineering faculty. He became the Philip Sporn Professor of Energy Processing in 1982. He was also director of the Laboratory for Electromagnetic and Electronic Systems and associate director of the Energy Laboratory. He was appointed director of the International Institute of Applied Systems Analysis in Vienna in 1984.

In 1989, a year after he retired from MIT, he joined CEOs and senior managers from seven Boston-area companies to found the CQM, where he was president (1990–98) and served on the board of directors. The center’s Cambridge location gave MIT faculty and staff great opportunities participate in important changes in American product design and manufacturing processes. And Lee was instrumental in organizing CQM’s chapter in Shanghai.

With Shoji Shiba and Robert Chapman Wood, he coauthored Integrated Management Systems: A Practical Approach to Transforming Organizations (John Wiley & Sons, 1999). He also studied worldwide anticorruption tactics with Transparency International.

He served on a number of NRC committees, including panels on the Policy Implications of Greenhouse Warming (1989–91), the Committee on International Organizations and Programs (1990–93), and the US National Committee for the Pacific Science Association (1989–99; chair, 1992–95).


Ping King (P.K.) TienPing King (P.K.) Tien (1919-2017)
NAE election: 1975; citation: “Inventor and engineering contributions to microwave amplifiers and integrated optical circuits and devices.”

P.K. Tien earned his bachelor’s degree from National Central University in Taiwan in 1942 and his master’s and doctorate, all in electrical engineering, from Stanford University in 1948 and 1952. He joined Bell Telephone Laboratories in 1952 and was appointed head of the electron physics research department in 1959.

Tien made important contributions in a number of fields in applied physics and electrical engineering. His work enabled advances in traveling-wave tubes and ferromagnetic amplifiers, backward-wave oscillators, noise in parametric devices, multiphoton processes in superconducting tunnel junctions, acoustoelectric interactions in solids, and integrated optics.

He was a pioneering founder of the field of integrated optics, an important adjunct to the field of fiber optics. His profound understanding of coupled electromagnetic waves led him to discover a simple but extremely elegant technique of coupling free space optical propagation modes to the guided modes of optical thin film waveguides. This discovery, which resulted in a “prism-film coupler,” revolutionized experimental investigations of light wave propagation in thin films.

In addition, he explored low-loss materials for passive thin film guides and active devices such as thin film modulators, deflectors, and switches. Through his theoretical study of magnetic fields, he contributed to the realization of low-loss garnet films and birthed the field of magneto-optical phenomena in thin films. He was also instrumental in novel studies of prisms, reflectors, lenses and polarizers for thin film optics.

In addition to the NAE, Tien was elected to the National Academy of Sciences, and he was a fellow of IEEE and the Optical Society of America.

He served on the NRC Ford Foundation Diversity Fellowships Predoctoral Review Panel on Engineering (1999–2001) and Committee on Microwave Processing of Materials: An Emerging Industrial Technology (1992–94).

Morgan Chuan-Yuan SzeMorgan Chuan-Yuan Sze (1916-2015)
NAE election: 1976; citation: “Contributions to the technology of petroleum refining and petrochemical process design and manufacture.”

Morgan C-Y. Sze was born May 27, 1916, in Tianjin, China. He graduated in 1935 from the Peking American School as valedictorian and entered Tsinghua University in Beijing. Unable to complete his studies there because of political unrest, he transferred in 1937 to MIT, where he received his bachelor’s degree (1939) and doctorate (1941), both in chemical engineering.

During a career that included work at DuPont, Hydrocarbon Research, Lummus (where he rose to vice president of research and development), and Wheelabrator-Frye, he authored numerous scientific papers, held some 80 US patents, and became an internationally recognized engineer.

He had an enduring belief in the role of science and technology for the betterment of individuals' lives and society as a whole. He also believed that a broad and deep education offered the best opportunity for a successful life, and that knowledge in one field could lead to insights or discoveries in another. He was deeply appreciative of the opportunity to start a new life in his adoptive country.


King-Sun FuKing-Sun Fu (1930-85)
NAE election: 1976; citation: “Contributions to pattern recognition in the solution of important societal problems.”

King-Sun Fu was the W.M. Goss Distinguished Professor of Engineering and director of the Intelligent Manufacturing Center at Purdue University, and a pioneer and universally acclaimed leader in the field of syntactic pattern recognition.

He was born in Nanking, China, on October 2, 1930. He received a BS from the National Taiwan University in 1953, an MS from the University of Toronto in 1955, and a PhD from the University of Illinois in 1959, all in electrical engineering.

From the beginning, Fu saw no conflict between basic research and its applications. He believed that if the basic research were sufficiently deep and powerful, it would solve many difficult practical problems. Conversely, he believed that important practical problems would not be successfully solved by ad hoc methods without involving a deep theoretical foundation.

While still in Taiwan, he worked in industry, first at the Taiwan Power Company and later with the Chinese Broadcasting Company. After he received his doctorate, he made the difficult decision to gain further experience by joining the Boeing Airplane Company as a research engineer in 1959. The desire to teach never left him, however, and during the spring of 1960 he taught a course at Seattle University. That fall, he accepted an appointment at Purdue University.

Shortly after Fu's arrival at Purdue, his department head, Thomas F. Jones, suggested that he spend a semester at the Research Laboratory of Electronics at the Massachusetts Institute of Technology. That experience marked the initiation of his interest in pattern recognition. On his return to Purdue, his interests expanded to machine intelligence, image processing, computer vision, and expert system development.

Fu was known for his innovative ideas and practical applications of them—for example, the identification and classification of crops from remotely sensed multisectorial data, the detection of irradiated chromosomes, and the computerization of a blood cell classification system. He also developed x-ray techniques for the automatic diagnosis of abnormalities of lungs, heart, liver, and pancreas and the identification and classification of fingerprints. More recently, his methods have been applied to integrated circuit chip and metal surface inspections, both important to industrial automation.

He published more than 300 papers and four books and was the founding editor of IEEE Transactions on Pattern Analysis and Machine Intelligence. He was also a visiting professor at Stanford University as a Guggenheim fellow and a visiting professor at the University of California at Berkeley. He supervised 75 PhD students who now hold positions of leadership in industry and academia.

For his contributions, Fu received numerous honors, including the American Society for Engineering Education Senior Research Award (1981), the Institute of Electrical and Electronics Engineers (IEEE) Education Medal (1982), and the Harry Goode Memorial Award from the American Federation of Information Processing Societies (1982).

He served on the NRC Panel on Discriminant Analysis, Classification and Clustering (1981–85).


Chang-Lin TienChang-Lin Tien (1935–2002)
NAE election: 1976; citation: “Contributions to the theory of heat transfer and for its application to difficult contemporary engineering problems.”

Chang-Lin Tien was chancellor of the University of California, Berkeley and a world leader in heat transfer and thermodynamics. He was a visionary who identified new, critical fields and then conducted pioneering research in those disciplines, elucidating essential elements and phenomena and important applications of his research. He was also an enthusiastic educator and leader.

Born in Wuhan on July 24, 1935, he was a high school student in Shanghai when he followed his family to Taiwan in 1949 to escape civil war in China. He received his bachelor’s degree from National Taiwan University in 1955 and, after a year of military service, came to the United States, where he earned his master’s degree from the University of Louisville (1957) and doctorate from Princeton University (1959), both in mechanical engineering.

He joined the faculty at UC Berkeley in 1959 as an assistant professor and became full professor in 1968. He rose to become chair of the Department of Mechanical Engineering (1974–81) and vice chancellor of research (1983–85). He left UCB briefly to accept appointment as executive vice chancellor at UC Irvine (1988–90), and returned to serve as chancellor (1990–97), the first Asian scholar appointed to the top position of a major US research university.

As one of the first investigators of heat transfer to focus on thermal radiation in gases, Tien provided a basis for quantifying the infrared radiation properties of gases and for generalizing these properties so that gases could be characterized in terms of fundamental variables, thus providing a foundation for current engineering approaches. He also made significant contributions to the understanding and determination of radiation transport in solids in the form of particulates and surfaces and was the first to provide a sound theoretical basis for determining dependent scattering

In addition, Tien made pioneering contributions in microscale thermal phenomena—phonon transport in nanostructures and semiconductor superlattices, non-Fourier heat conduction in thin films, femtosecond laser interactions with thin films and micromechanical structures, heat transport in random media, picosecond optical properties of porous silicon, and microscale laser interactions with liquids. His efforts in research, the supervision of students and postdoctoral scholars, and the founding of a new journal, Microscale Thermophysical Engineering all changed the field and led to the new discipline of microscale heat transfer. He coauthored, with John Lienhard, the textbook Statistical Thermodynamics, edited 16 volumes, and published more than 300 research papers and monographs

He received numerous honors. In 1962 he became the youngest professor to win Berkeley’s prestigious Distinguished Teaching Award, and in 2001 he was awarded the NAE Founders Medal. He was elected a fellow of the American Academy of Arts and Sciences, a member of the Academia Sinica, and a foreign member of the Chinese Academy of Sciences. The asteroid Tienchanglin, discovered by the Zi Jin Mountain Observatory in China, was named for him in 1999.

He was an unofficial “ambassador” to many countries, especially in Asia, in terms of public service. He was a member of the board of trustees of the Asian Foundation, advisor to the governor of Hong Kong, chair of the San Francisco Bay Area Economic Forum, and a member of the board of directors of Kaiser Foundation Hospitals and of the Aspen Institute Domestic Strategy Group.

He was elected a member of the NAE Council (1998–2001) and served on NAE membership committees, among others.
