Yaoqing Yang, Grad Student yyaoqing@andrew.cmu.edu
Ph.D. candidate, ECE, CMU
B.S., EE, Tsinghua University, 2013

Recently I am focusing on my PhD research to explore efficient algorithms for delay-tolerant and fault-tolerant distributed machine learning systems. I am trying to apply information-theoretic techniques into problems on distributed computing and graph data analysis. Before that I was an undergraduate student in Tsinghua University and my research was on graph-theoretic algorithms for high-interference communication networks.

I travel a lot 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 Studenthaewon@cmu.edu
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 Studentpraveen1@andrew.cmu.edu
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, Grad studentsanghamd@andrew.cmu.edu
Ph.D. candidate, ECE, CMU

Previous Lab Members



Ana Beisy Cruz, Undergradanabeisy_2008@hotmail.com
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.

Karthik Ganesan, Undergraduate student (2010-13) karthik3@stanford.edu
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 mgregan@andrew.cmu.edu
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.
