Saugata Basu has a joint appointment as a Professor of Mathematics and Computer Science with Mathematics as his home department. He comes to Purdue from the Georgia Institute of Technology. His research interests are in real algebraic geometry, computational algebra and geometry, and theoretical computer science. Basu has previously held positions at the University of Michigan, IBM T. J. Watson Research Center, and the Mathematical Sciences Research Institute in Berkeley. He received his PhD from the Courant Institute, New York University and his BTech degree from the Indian Institute of Technology, Kharagpur. Basu has also held visiting positions at Universite de Rennes, the Institute of Mathematics and its Applications in Minneapolis, and the Institue Henri Poincaré, Paris.
