Academic Experience

Graduate Research Assistant 6/2012 - Present

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

  • Investigated 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.
  • Surveyed 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.
  • Developing novel techniques to estimate Precoder matrix used in LTE transmission. (LTE Project)
    • Implemented three different methods to estimate, at the receiver, the precoder matrix used by an LTE transmitter, namely – Blind equalization using MCMA/AMA, Maximum Likelihood hypothesis testing and using Cluster Variance.
    • Observed a favorable trade-off between error performance and computation complexity with a simplified hypothesis testing method, compared to other techniques. Further research is ongoing.
  • Developing a video-quality aware rate control algorithm for real-time video conferencing applications, to optimize end-user experience, and reduce network congestion. (Rate Control Project)
    • Designed a video rate adaptation policy using a Markov Decision Process (MDP).
    • Propose to estimate the optimal policy using Q-learning.
    • Evaluation of performance and further research is ongoing.

Graduate Teaching Assistant 8/2011 - 5/2012, 8/2015 - current

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
