Profile

I'm a researcher at Precog@IIITD, and a fifth year PhD student at IIIT-Delhi. Advised by Dr. Ponnurangam Kumaraguru ("PK"), my areas of interest are cyber crime, privacy and security in online social media, machine learning, deep learning, natural language processing, and data mining. I completed my Masters degree in Computer Science (specialization in Information Security) in 2012 from IIIT-Delhi. I got by Bachelors degree in Computer Science and Engineering in 2010 from Rajasthan Technical University, a state university in India. Geeky, enthusiast, opportunist, optimistic, and a die-hard Lamborghini fan.
