He is known for his work on crowdsourcing (especially Amazon Mechanical Turk)[3][4][5] and on integrating human and machine intelligence.[6]

He also worked on the intersection of data mining with economics, through the EconoMining project.[7] The finding that good spelling and grammar can lead to improved product sales was discussed in the media.[8][9][10][11][12]

He is the author of the blog "A Computer Scientist in a Business School", where he often writes about crowdsourcing and other topics. Many of his blog posts are frequently cited in the press and in academic papers.[13]


In 2004, Panos Ipeirotis was awarded a Ph.D. in Computer Science from Columbia University. In the same year, he joined New York University Stern School of Business where he is currently a Professor and George A. Kellner Faculty Fellow at the Department of Information, Operations, and Management Sciences. He also worked for oDesk (now UpWork) as Academic-in-Residence, and at Google as a Visiting Scientist.


Ipeirotis is the recipient of the 2015 Lagrange Prize in Complex systems for his contributions in the field of Social media, User-generated content, and Crowdsourcing.[14] Additionally, he has received nine "Best Paper" awards and nominations and a CAREER award from the National Science Foundation.[15][16][17]
