Johannes Gehrke is a Technical Fellow at Microsoft focusing on AI.{{Cite web|url=https://www.microsoft.com/en-us/research/blog/making-the-future-of-work-work-for-you-with-dr-johannes-gehrke/|title=Making the future of work work for you with Dr. Johannes Gehrke|date=2019-07-17|website=Microsoft Research|language=en-US|access-date=2019-07-19}} He is an ACM Fellow, an IEEE Fellow, and he received the 2011 IEEE Computer Society Technical Achievement Award and the 2021 ACM SIGKDD Innovation Award. From 1999 to 2015, he was a faculty member in the [http://www.cs.cornell.edu Department of Computer Science] at Cornell University, where at the time of his leaving he was the Tisch University Professor of Computer Science.{{Cite web|url=https://news.cornell.edu/stories/2015/01/gehrke-joachims-honored-work-computer-science|title=Gehrke, Joachims honored for work in computer science|website=Cornell Chronicle|language=en-US|access-date=2019-10-03}}
Gehrke is best known for his contributions to database systems, data mining, and data privacy. He developed some of the fastest data mining algorithms for frequent pattern mining, sequential pattern mining, and decision tree construction and one of the first sensor network query processors which pioneered in-network query processing for wireless sensor networks, and he is known for his work on data privacy. His work on data privacy resulted in a new version of OnTheMap published by the US Census Bureau, the very first public data product published by any official government agency in the world with provable privacy guarantees (using a variant of Differential Privacy).{{Cite web|url=https://lehd.ces.census.gov/applications/help/onthemap.html#!confidentiality_protection|title=OnTheMap Help and Documentation, Confidentiality Protection|website=United States Census Bureau|access-date=2020-12-09}}
Education
Johannes Gehrke studied from 1990 to 1993 computer science at the Karlsruhe Institute of Technology; he received an M.S. degree from the Department of Computer Science at the University of Texas at Austin in 1995 and a PhD from the University of Wisconsin, Madison in 1999 for a thesis in data mining.
Career
From 1999 to 2015, Gehrke was a professor in the Department of Computer Science at Cornell University.
