Tamal Dey's primary research area is Computational Geometry and Topology with applications to topological data analysis, geometric modeling, computer graphics, and mesh generation. He has (co)authored two books``Curve and surface reconstruction: Algorithms with Mathematical Analysis" published by Cambridge University Press and "Delaunay Mesh Generation" published by CRC Press. (Co)author of more than 200 scientific articles, Dey is an IEEE and ACM Fellow. He has also been inducted as a Fellow by Solid Modleing Association. He serves in various editorial and executive boards and routinely gives invited lectures at various academic forums.

Before joining Purdue, he was a faculty at the Computer Science & Engineering department of the Ohio State University (1999--2020) where he led the Jyamiti research group on geometric and topological data analysis and headed the NSF sponsored TGDA TRIPODS Phase I Institute. He was the interim Chair of the department at OSU (2019-2020). For more details, see the Wikipedia page and homepage https://www.cs.purdue.edu/home...
