William Ian Gasarch (/ɡəˈsɑːrʃ/ gə-SARSH;[1] born 1959[2]) is an American computer scientist known for his work in computational complexity theory, computability theory, computational learning theory, and Ramsey theory. He is currently a professor at the University of Maryland Department of Computer Science with an affiliate appointment in Mathematics.
Gasarch is a frequent mentor of high school student research projects; one of these, with Jacob Lurie, won the 1996 Westinghouse Science Talent Search for Lurie.[3] He has co-blogged on computational complexity with Lance Fortnow since 2007. He was book review editor for ACM SIGACT NEWS from 1997 to 2015.
Education
[edit]Gasarch received his doctorate in computer science from Harvard in 1985, advised by Harry R. Lewis. His thesis was titled Recursion-Theoretic Techniques in Complexity Theory and Combinatorics.[4] He was hired into a tenure track professorial job at the University of Maryland in the Fall of 1985. He was promoted to Associate Professor with Tenure in 1991, and to Full Professor in 1998.[5]
Work
[edit]Gasarch co-founded (with Richard Beigel) the field of Bounded Queries in Recursion Theory[6] and has written many papers in the area capped off by a book on the topic co-authored with Georgia Martin, titled Bounded Queries in Recursion Theory.[7] He has published books such as Problems with a Point,[8] a book with a broad view on mathematics and theoretical computer science which he co-authored with Clyde Kruskal and includes works by other professors such as David Eppstein.[9] He also co-founded the subfield of recursion-theoretic inductive inference named Learning via Queries[10] with Carl Smith. More recently he has been more involved with combinatorics, notably Ramsey Theory.[11][12][13] He has written three surveys of what theorists think of the P vs NP problem: in 2002, 2012, and 2019.[14][15][16] In 2020 he wrote Mathematical Muffin Morsels: Nobody Wants a Small Piece with Erik Metz, Jacob Prinz, and Daniel Smolyak. [17]
Blog
[edit]Lance Fortnow began writing a blog on theoretical computer science with an emphasis on complexity theory in 2002.[18] Gasarch was a frequent guest blogger until 2007 when he became an official co-blogger.
