J. Harshan

Welcome to my homepage. I am an Assistant Professor in the Department of Electrical Engineering, Indian Institute of Technology Delhi. Prior to joining IIT Delhi, I worked as a Researcher in the CyberSecurity group at Advanced Digital Sciences Center, Singapore. Before that I worked as a Research Fellow in the Division of Mathematical Sciences, Nanyang Technological University, Singapore and in the Department of Electrical and Computer Systems Engineering at Monash University, Australia. I obtained Ph.D. from the Department of Electrical Communication Engineering, Indian Institute of Science, India.

PhD openings

I am looking for bright and enthusiastic young researchers to join our group as Ph.D. scholars to work in the broad areas of security and privacy. If interested, please drop me your CV at jharshan@ee.iitd.ac.in. You may also refer here for more details on PG admissions at IIT Delhi.
