{{short description|American computer scientist}} {{for|the British journalist and editor|Deborah Joseph (editor)}} '''Deborah A. Joseph''' is an American computer scientist known for her research in computational geometry, computational biology, and computational complexity theory. She is a professor emeritus of computer science at the University of Wisconsin–Madison.{{r|em}}
==Education and career== Joseph graduated from Hiram College in 1976 with an interdisciplinary major in ecology.{{r|cstb}} She earned her Ph.D. in 1981 at Purdue University. Her dissertation, ''On the Power of Formal Systems for Analyzing Linear and Polynomial Time Program Behavior'', was supervised by Paul R. Young.{{r|mg}}
At Wisconsin, Joseph was a recipient of the Presidential Young Investigator Award of the National Science Foundation. She was also an active member of the Computer Science and Telecommunications Board of the National Research Council.{{r|cstb}}
