Introduction
I am a 1st year Computer Science PhD student at University at Buffalo , The State University of New York. I completed my Masters in Computer Science from Georgia Institute of Technology and my Bachelors from IGIT,GuruGobind Singh Indraprastha University in India. My current advisors are Geoffrey Challen and Steven Ko. My advisor at Georgia Tech was Nick Feamster. My research interests lie in the field of computer networks, network security and mobile computing. I have done research on Phishing attacks and the SCTP protocol in the past. My current research focuses on security in smartphones, more specifically in the Android phone. I am the TA for CSE421- Operating Systems this semester.

Research
An overview of my research so far is as follows-
My PhD research is on smartphone security, more specifically on Android security. In the previous semester i.e. Fall 2011, my colleagues and I developed a system called StealAP which demonstrates how a smartphone can be a new attack vector in Wi-Fi security. In Summer 2009 I worked with Nick Feamster on Phishing attacks at Georgia Institute of Technology. Under his guidance, I developed a firefox extension which detected phishing sites using digital watermarking. I also did longitudinal analysis of phishing sites and based on the phish data that I collected from Phish Tank, I identified some very interesting trends based on the geographical location and time of submission of the sites. Furthermore, I categorized the sites into categories like banking, shopping and finance and found the percentage of the sites in each category. In Summer 2008, I worked as an intern at the Software Research Institute in Athlone Institute of Technology, Athlone, Ireland. Apart from being a great international experience, the internship gave me an outstanding opportunity to do cutting edge research in the Networking field. I worked on the Seamless Use through Network Abstraction Technologies (SUNAT) project. The main goal of the project was to design a platform for seamlessly distributing multimedia data across heterogeneous mobile networks. The main task assigned to me was to convert an RTP/RTCP application to work over Stream Control Transmission Protocol (SCTP) instead of UDP. The application used was the PJMedia module of PJSIP (an existing SIP stack). Based on the team's previous work and my own research, I made changes to the MEDIA side of PJSIP.
