EXPERIENCE
Feb 2024 - now
Postdoctoral Research 
Fellow

Vanderbilt University, United States

 I am working under Xenofon Koutsoukos on reinforcement learning based cyber agents to identify cyber-attacks in large scale enterprise networks.

Aug 2022 - Sep 2023
Research Fellow

Continental-NTU Corporate Lab, Singapore

I have worked on spoofing attacks on GPS location data in fleet operator's network of Electric Vehicles resulting in misinterpretation of location information of vehicles. 

Internships
