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.[4] She came to the University of Hawaiʻi at Hilo in 1990,[7] 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.[3]
