Judith Gersting

Judith Lee MacKenzie Gersting (born August 20, 1940) is an American mathematician, computer scientist, and textbook author. She is a professor emerita of computer science at Indiana University–Purdue University Indianapolis and at the University of Hawaiʻi at Hilo.

Education and career
Gersting graduated from Stetson University in 1962, and completed a Ph.D. in mathematics in 1969 at Arizona State University. Her dissertation, Some Results on $$t$$-Regressive Isols, concerned recursive function theory and was supervised by Matt Hassett.

After holding a faculty position in the department of mathematical sciences at Indiana University–Purdue University Indianapolis (IUPUI) for ten years, and becoming a full professor there, she spent a year at the University of Central Florida before returning to IUPUI in 1981 as professor of mathematics and acting chair of the department of computer and information science. She came to the University of Hawaiʻi at Hilo in 1990, and chaired the computer science department there for many years. After retiring from the University of Hawaiʻi, she became a part-time faculty member at IUPUI.
