PROFESSIONAL & RESEARCH EXPERIENCE

Research Assistant May 2005 August 2011

Indiana University, Bloomington, IN, USA

Conducted and published the following network security research under the direction of Prof. Minaxi

Gupta and Prof. Steven Myers:

Analyzed the network-level characteristics of spammers and their spamming behavior; examined the

link structure of Web graphs rooted at forum spammers URLs; implemented noble spam classifiers

for forum and email spam detection respectively using machine learning algorithms, Java, and Python

[1,2,6,13].

Implemented a fast energy-efficient IPsec session reestablishment scheme using strongSwan and C;

designed and simulated a practical and effective power-cycling scheduler for an energy saving scheme

on WiFi mobile devices with required IPsec for VPN using Indiana University wireless network

session traces and Python [3].

Identified malware infection dynamics by collecting and inspecting network logs of Asprox bots, web

hosts delivering malicious JavaScript codes, and web servers infected by Asprox SQL injection attacks

[4].

Conducted the comprehensive performance evaluation of SSL on PDAs by adapting and

benchmarking OpenSSL on MS Windows Mobile PDA [5].

Investigated the performance overhead of IPsec by developing a test suite and modifying Openswan,

an open source IPsec implementation [7].

Developed a type inferencing scheme to automatically translate Matlab scripts to C/C++ codes using C++

under the direction of Prof. Arun Chauhan.
