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, one of the first sensor network query processors which pioneered in-network query processing for wireless sensor networks, and his work on data privacy, which resulted in the very first public data product published by any official government agency in the world with provable privacy guarantees.

Education

Johannes Gehrke studied from 1990 to 1993 computer science at the Karlsruhe Institute of Technology, received an M.S. degree from the Department of Computer Science at the University of Texas at Austin in 1995, and his 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. His research group was popularly known as the Big Red Data Group. Gehrke was also Chief Scientist at Fast Search and Transfer.

Gehrke received a National Science Foundation Career Award,[3] a Sloan Research Fellowship,[4] and a Humboldt Research Award. In 2011, he received the IEEE Computer Society Technical Achievement Award[5] and a Blavatnik Award for Young Scientists.[6] In 2014, he became a Fellow of the Association for Computing Machinery[7], and in 2020 he was elected an IEEE Fellow.[8].

Books

Since its second edition, Gehrke has been a co-author of one of the main textbooks on database systems, commonly known as the Cow Book.[9]

gollark: <@184468521042968577> `is_valid_lua` isn't deliberately bad, but it's also IIRC not actually used anywhere.Also, that person was bundling potatOS with some other project but wanted people to be able to remove it even more easily if they don't like it. This feature does actually work but must be enabled before installation. Weirdly enough factorizing small semiprimes is beyond many users.
gollark: You could say that.

gollark: PotatOS has `persistent` for that. Nobody uses it, because it's in PotatOS, and honestly not that good. https://pastebin.com/jE4guV48You need to explicitly save it because I found out that any other way was very very hard to do, and kind of wasteful.
