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. 

Research Interests: 

Wireless networks, Coding theory, Distributed Storage Networks, Wireless Security, Cyber-Physical Systems, Communication Systems


I am looking for prospective Ph.D. students to work in the areas of (i) Wireless security and cyber-physical systems, and (ii) Coding for networked systems. If interested drop me an email along with your CV.
