I am a graduate student pursuing a PhD at the University of Maryland, College Park,
in the department of Electrical and Computer Engineering. My research interests include
4th generation wireless communication networks, with a specific focus on receiver
design and equalization techniques, and rate control for real-time communications.
My objective is to do an internship to get valuable industrial research experience
in these or related areas.

- Academic Experience
Graduate Research Assistant 6/2012 - Present
- 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
- 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, 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.
Graduate Teaching Assistant 8/2011 - 5/2012
- 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.
- 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
Congestion Control for Real-time Communications 6/2014 - 8/2014
- Implemented a congestion control mechanism for a real-time communication system developed at Bell Labs.
- Currently evaluating its performance and comparing with results from existent literature.
A Multi-protocol Traffic Generating Tool for FreeBSD based systems 5/2010 - 7/2010
- 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
- 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:
- 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
- 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.
