Rohit Parikh's Web site
Rohit Parikh's entire career has revolved around logic, which includes not only parts of computer science but also mathematics and philosophy. Parikh has taught at Stanford, NYU, Boston, SUNY Buffalo, Bristol and Panjab universities. He has also held temporary research positions at IBM, Bell Labs, Caltech, MIT and Berkeley.
Parikh's many former students, not only from CUNY but also from Boston University, Stanford, NYU and Columbia, are teaching in places as varied as
Brown University, University of Maryland, Haifa, Chennai, Paris, CUNY of course, and many others.
Education:
Ph.D., Harvard University - 1962 (Mathematics (Mathematical Logic))
A.M., Harvard University - 1959 (Mathematics)
A.B., Harvard College - 1957 (Physics (magna with highest honors in physics))
Areas of Expertise:
Rohit Parikh's current specialty is social software, or more prosaically, logic as applied to society. This interest has led to an interest in game theory and logic of knowledge. Previous areas include formal languages, nonstandard analysis, proof theory and dynamic logic.

Abstract: We look at the history of research on vagueness and the Sorites paradox. That search has been largely unsuccessful and the existing solutions are not quite adequate. But following Wittgenstein we show that the notion of a successful language game works (SEP stands for society for exact philosophy) (Conferences, Seminars and Symposiums: Conference Presentation) 2021
