Dr. Pradeep Kumar Rai is an Assistant professor of Mathematics at Ecole Centrale School of Engineering, Mahindra University. He received his Ph.D. in Mathematics from Harish-Chandra Research Institute, Allahabad in 2015. Later he worked as a PBC Post-Doctoral Fellow in Bar-Ilan University, Israel (2015-2017). Prior to joining Mahindra University he held the position of INSPIRE Faculty at Harish-Chandra Research Institute, Prayagraj (2019-2021) and Indian Institute of Technology Patna (2017-2019). His area of research is Group Theory. His Ph.D. thesis is about the automorphisms of groups. It studies class-preserving automorphisms, and prime power groups having abelian automorphism group. His more recent work is about second cohomology group of prime power groups. These works have been published in journals such as Journal of Algebra, Journal of Pure and Applied Algebra, International Journal of Algebra and Computation and others.
