Profile

Dr. Neeraj Kumar Dhanwani is an Assistant Professor, in the department of Mathematics in the Faculty of Mathematical Sciences, South Asian University, Delhi, India. Before joining SAU, he was NBHM Postdoctoral fellow with Prof. Mahender Singh in Department of Mathematical Sciences, IISER Mohali. He completed his PhD under the guidance of Prof. Kashyap Rajeevsarathy from IISER Bhopal in Nov. 2020. 

His research is broadly Low Dimensional Topology, in particular, he works on mapping class groups of surfaces and quandles associated with classical knots. Recently, he has developed interest in algebraic and geometric aspects of Artin and Coxeter groups.
