Rudolph C. Hwa (born November 1, 1931) is an American theoretical physicist and Professor emeritus at the University of Oregon. His areas of interest include the strong interaction, nonlinear dynamics, fluctuations, and quark–gluon plasma. He was elected an American Physical Society Fellow in 1995.

Hwa Chia-chao was born in Shanghai, China, in 1931.^[2][1] He arrived in the United States in 1949, and became a naturalized citizen in San Francisco in 1962.^[1]

He completed three degrees in electrical engineering at the University of Illinois Urbana: a B.S. in 1952, an M.S. in 1953, and a Ph.D. in 1957. Hwa earned his 1962 Ph.D. in physics at Brown University,^[1] with a dissertation titled, Study of pion-hyperon resonances by dispersion relations in the unphysical sheet, advised by David Feldman.^[3]

Between 1962 and 1966, Hwa held research positions at the Lawrence Radiation Laboratory and at the Institute for Advanced Study, Princeton. His first faculty position was at the Institute for Theoretical Physics at State University of New York at Stony Brook, and he joined the faculty of the University of Oregon in 1971.^[4] He was named professor emeritus in 1997.^[5][1]
