Academic Experience

Graduate Research Assistant 6/2012 - Present

ECE Dept., University of Maryland, College Park, MD

  • Investigating Delay Tolerant Networks (DTNs), to develop analytical models to understand the Epidemic Routing protocol. (DTN Project)
    • Evaluated several mathematical models using discrete time equivalents of continuous time Markov processes as the basis, such as jump Markov processes.
    • Simulated the efficiency of the models using MATLAB.
  • Surveying established methods of blind equalization in wireless communication systems to develop a novel “Blind receiver” for LTE systems. (LTE Project)
    • Identified several blind equalization techniques for application in LTE.
    • Designed MCMA/AMA equalizer algorithm for a 2x2 MIMO-OFDM system in MATLAB. Compared performance with traditional non-blind equalizers.
  • Examined several existent blind channel estimation methods developed for wireless communication systems. (LTE Project)
    • Evaluating a candidate technique based on Noise-subspace methods and investigating its performance benefits over traditional approaches and the MCMA/AMA approach devised, to help develop an improved version of the MCMA/AMA equalizer.

Graduate Teaching Assistant 8/2011 - 5/2012

ECE Dept., University of Maryland, College Park, MD

  • Assisted in teaching junior level Electrical Engineering courses.
  • Responsible for grading homework and midterm exams and final exams.
  • Guided students through homework and additional course material at office hours and in one-on-one discussion sessions.
    • Several students observed improved performance and confidence in homework and exams.
  • Developed weekly quizzes to help students retain the class material better.
    • In a survey, a majority of the students found the quizzes very beneficial.

Some Equilibrium Properties of Rate Control Protocol
(B.Tech Thesis)
7/2010 - 5/2011

EE Dept., Indian Institute of Technology, Madras, India

  • Analyzed the stability, rate of convergence and performance of communication systems using control theoretical concepts, by modeling the system by linear delay differential equations.
  • Investigated congestion control in Internet from a control theoretical perspective: understanding the impact of buffer size and Active Queue Management algorithms on stability and congestion in the network.

Professional Experience

A Multi-protocol Traffic Generating Tool for FreeBSD based systems 5/2010 - 7/2010

Internship at Juniper Networks Pvt. Ltd. (India)

  • Developed network packet generating tool based inspired by “Bit-Twist”, a libpcap-based packet generator.
    • It takes in a variety of parameters from user including L2 (Ethernet header) options, L3 options, rate (bps or pps), time to send, etc. and generates packets and sends on a given interface
    • It replays captured packets, displays several network statistics such as bits per second (bps), number of packets successfully sent, number of packets in error, etc.
    • An open source version is available at: http://sourceforge.net/projects/framegen
  • Received high praise for the quality of my code, work ethic and timely completion of the project for use in a Lab environment from my manager, along with a strong recommendation for my graduate school application.

Factors Affecting Network Performance: Measurement and Modification 5/2009 - 7/2009

Internship at the Institute for Development and Research in Banking Technology, India

  • Surveyed the Cisco IOS® Software command-line interface (CLI) for the routers and the switches.
  • Studied network performance with network impairments on a variety of simple local area network topologies like switches and routers by using “Anue Systems Network Emulator”.
  • Gathered data and investigated performance of the network under impairments using “ping” commands and by testing video streaming applications.
