Current Lab Members

Pulkit Grover, Principal Investigator
Ph.D., Electrical Engineering & Computer Sciences, UC Berkeley, 2010
M.Tech, B.Tech., Electrical Engineering, IIT Kanpur, 2005, 2003

I am an Assistant Professor in the Department of Electrical & Computer Engineering at CMU. I hold B.Tech. and M.Tech. degrees in electrical engineering from IIT Kanpur, and a Ph.D. from UC Berkeley supervised by Anant Sahai. I also spent 18 months at Stanford as a postdoc in Andrea Goldsmith's group.

I play tennis, love hiking, traveling, and doing creative and geeky artwork. When in India, I like to fight kite duals.

Yaoqing Yang, Grad Student
Ph.D. candidate, ECE, CMU
B.S., EE, Tsinghua University, 2013

Recently I am focusing on my PhD research to explore the possibility of building reliable circuits out of noisy components. Promising schemes span coding, message passing and control on graphs. Before that I was studying the communication limitation in high-interference mobile networks. In the future there might be a chance to combine these two seemingly independent lines into general noisy computation.

I love travelling and hiking but I haven't been to Tibet which is my ultimate dream. In preparation, I exercise regularly. Other hobbies include reading comics and listening to light music.

Haewon Jeong, Grad
Ph.D. candidate, ECE, CMU
B.S., Electrical Engineering, Korea Advanced Institute of Science and Tech. (KAIST)

I am interested in Big Data networks and designing power-efficient communication in such networks. I am now working on developing an encoding/decoding scheme that optimizes system-level energy for short-distance communication in a data center. Before joining Professor Grover's group, I did research on computer networks, especially on building high-performance middleboxes. Since it is another approach to improve the performance of high-end networks at the computer-system level, I hope this experience to give me better view for my current research.

I like running and programming, but recently I found out that the best thing that relieves my stress is cooking. I'm only good at Korean cuisine for now, but I really enjoy exploring many different cuisines which were not easily found in my country.

Praveen Venkatesh, Grad
Ph.D. candidate, ECE, CMU
B.Tech., Electrical Engineering, IIT Madras

My interests lie broadly in the area of applying concepts from signal processing and information theory to neuroscience. My current line of research involves understanding the EEG/MEG source localization problem in order to answer questions about seizure foci in patients with epilepsy. I am also working on problems related to the application of directed information and Granger Causality in neuroscience.

While not working on research, I enjoy (spending more time than I save on) programming routines to optimize the task of programming routines (and writing self-referential sentences (with nested parentheses)). I've also started learning how to play Carnatic music on the violin.

Sanghamitra Dutta, PhD
Ph.D. candidate, ECE, CMU
B.S., Electrical Engineering, IIT Kharagpur

I am interested in Information Theory and Statistical Inference. I am exploring the problems arising in neural signal acquisition and inference, from an information-theoretic perspective. Prior to joining CMU, I worked on the applications of compressed sensing and sparse reconstruction in Radar Imaging. I am currently using tools from compressed sensing and coding theory in the design of efficient sensing strategies under limitations of energy and cost.

Apart from research, I am also interested in dramatics and like to act in plays. I am also a board member of the Indian Graduate Student Association, and enjoy coordinating various student activities in the campus.


Previous Lab Members

Ana Beisy Cruz,
B.S. candidate, ECE, CMU, 2015

Over the past few decades, brain stimulation has been used to treat a variety of medical conditions. A few examples of such conditions are epileptic seizures and Parkinson's disease. In both cases, brain stimulation is used to lessen the effects of the disease and to improve the quality of life of the patient. My goal is to understand how the main brain stimulation devices in the market work and to find ways to improve them.

My hobbies include cliff jumping, blogging, drawing, and building a variety of things. I grew up in Dajabon, the Dominican Republic with more pets than I could count.

Majid Mahzoon, MS
Ph.D. candidate, ECE, CMU
B.S., Electrical Engineering, Sharif University

I am from Mashhad, Iran. I received my B.S. degree in Electrical Engineering, Communications, from Sharif University of Technology, the best technical school in my country. During my undergrad studies, I got interested in Information Theory and its applications in various fields and did some research in related areas such as Implicit Communication, Cognitive Interference Channels, Interactive Channel Coding and Data Communication over the GSM Voice Channel. When I am free, I enjoy playing and watching soccer and listening to music.

Phillip Fynan, Summer intern (2013)
B.S. candidate, EE, Calvin College

I worked on research into green communications. Specifically, I worked on determining the power consumption of LDPC codes implemented in FPGAs and ASICs. Originally, I grew up in Santa Rosa, CA.

Outside of school, I play baroque and renaissance recorder.

Karthik Ganesan, Undergraduate student (2010-13)
B.S., EE, UC Berkeley,
Ph.D. Candidate, Stanford University
I am interested in a variety of topics in coding theory, statistics, applied probability, and theoretical computer science. My current focus is in energy-efficient communication and robust computation. At Berkeley, I spent three years working with Pulkit, Yang Wen, and Professors Jan Rabaey and Andrea Goldsmith on energy consumed in decoding under various theoretical models of VLSI implementations, and then developed a large set of decoding power models based on post-layout circuit simulations. These models helped raise several code design questions, and allowing search of code + modulation + decoding combinations which are transmit + processing power-efficient for a variety of communication settings. I credit my involvement in the group as one of the most important parts of my education and a major source of motivation in pursuing graduate school.

I am originally from the Bay Area, CA. In my free time, I enjoy watching sports, hiking, listening to orchestral music, and attending symphony concerts.

Yang Wen, Undergraduate student (2011-12)
B.S., EE, UC Berkeley
Currently at Oracle Corporation
I worked on research about green communication. I designed Multi-bits LDPC (Low-Density Parity-Check) decoders using ST 90nm technology and investigated tradeoff among different decoders in terms of power, layout, timing and error probability. I built a model in MALTAB to demonstrate the relationship between decoders' power consumption with different bits of messages, girths, and degrees of variable nodes and check nodes.

My current work focuses on design of CPU for next-generation of high-performance servers.

I was born and raised in Tianjin, China. Outside of my work, I like biking, hiking and kayaking.

Max Regan, Undergradate Student
B.S. candidate, ECE, CMU, 2015

I work in two areas. The first was creating a MATLAB model that could simulate a network of wireless power transmitters, receivers, and unpowered repeaters. I used it to examine and optimize power transfer efficiency. The second was design and test a proof-of-concept for detecting attackers of hardware circuits. This was done by detecting minute variations in magnetic fields caused by the presence of probes near the attacked circuit.

Born in Georgia, raised in Massachusetts and Kansas, living in North Carolina, and going to school in Pennsylvania, I'm from all over the US. When I'm free, I can be found hiking, programming, or playing rugby.

Rahshel Brown, Undergraduate
B.S. candidate, ECE, CMU, 2015

I am exploring the tradeoffs present when trying to use a single EM wave to transmit information and power.

I'm from Queens, New York. When I'm not working, I enjoy dancing and occasionally choreographing in the styles of hip hop and dancehall.

Ramon Cepeda Jr., MS
MS Candidate, ECE CMU

I am working on a channel model in MATLAB that is up to par to the 802.11ad standard that would help us investigate the benefits of adaptability and reconfigurability to achieve total energy minimization of millimeter-wave communications links.

I like to run and play basketball. I was born in New York City. I am an 18 year old graduate student.
