Biographies

Name: Nima Anari (Ahmadipouranari)
Email: cs70.anari@gmail.com
Office hour: Tuesdays 11-12 in 611 Soda
Discussion sections: n/a
Random fact: Nima is a competitive programmer.
Undergraduate institution: Sharif University of Technology, Iran
Research interests: I am a fourth-year graduate student working with Satish Rao. Currently I am mostly focused on online learning algorithms with some combinatorial optimization twists. Several weather forecasters tell you whether it's rain or shine each day. Do you take an umbrella with you or not? I work on algorithms for (more sophisticated) problems of this kind.
Internships:
  • D.E. Shaw & Co. (a hedge fund): The problem I worked on was very similar to the weather forecasters problem, but it was in a financial context.
  • Facebook: Worked on a statistics prediction model for ads.
  • Jane Street



Name: Claire Baek
Email: cs70clairebaek@gmail.com
Office hour: Mondays 10-11am in 380 Soda
Discussion sections: Mon, Wed 6-8pm at 87 Evans
About: I am a 4th year graduate student under Professor Costas Spanos. I received my B.S. in Chemical Engineering at Stanford University in 2010, and an M.S. in Electrical Engineering at Berkeley in 2012, and am currently pursuing my Ph.D in the same department. I spent half of my life in the US and half in South Korea.

My research focuses on process monitoring for semiconductor manufacturing. A size of one transistor has gotten so small and the geometry very complex that tight control in manufacturing is now needed for companies to be profitable. I apply a wide range of data mining techniques to help out this task. This summer, I interned at ASML, the biggest manufacturer of photolithography (tool used in "printing" out circuits) tools.



Name: Kate Harrison
Email: ucb.ta.kate@gmail.com
Office hour: TBD
Discussion sections: none
Research website: http://inst.eecs.berkeley.edu/~harriska/
About: Kate Harrison is a fifth-year graduate student. In 2009, she received a BS in Electrical and Computer Engineering as well as a BS in Mathematics from Oregon State University. In 2011, she received a MS in EECS from UC Berkeley. She was the head GSI for CS 70 in spring 2013.

While at UC Berkeley, she has worked with Anant Sahai to study spectrum whitespaces, a new idea aimed at making more spectrum available for innovators at no cost by using existing spectrum more efficiently. Her work has focused on quantifying the amount of such spectrum which is practically available as well as proposing modifications to regulations which offer increased benefits to all parties involved. One of her papers recently received the 2012 IEEE DySpAN best student paper award. She encourages interested students to ask her about her work as she enjoys sharing her enthusiasm for the subject.

In the summer of 2012, Kate interned at Tarana Wireless, a Berkeley startup aiming to provide non-line-of-sight wireless backhaul for cellular links. While there, she built and maintained a system performance visualization tool to help with troubleshooting.

Please email Kate with any logistical questions about the class that cannot be posted to Piazza.



Name: Alex Kantchelian
Email: akant.ucb.ta@gmail.com
Office hour: n/a
Discussion sections: MW 3:00 PM - 4:00 PM, both in 405 Soda.
About: I am a 3rd year PhD student in computer science, co-advised by Anthony Joseph and Doug Tygar. My research interests lie in Security, Machine Learning, and the intersection thereof. I currently investigate how machine learning algorithms (algorithms that learn from previous observations in order to make predictions on current observations) can safely replace or at least supplement traditional anti-virus software. So it's basically about having the machine learn to recognize malicious programs.

I've previously obtained my B.S. from the Ecole Polytechnique in France. I have interned at Amadeus in air ticket fraud detection, and Yellow Pages in website abuse detection.

I have taken advantage of some bay area local sport opportunities over the past years. Windsurfing in the marina was among the shortest-lived, messiest experiences of all.

Office hour: Fridays 4:30-5:30pm in 529 Cory
Discussion sections:
Random fact: Aadithya is also interested in computational finance and investing in the stock market. Someday, he hopes to come up with a magic algorithm that lets him make gazillions of dollars by exploiting inefficiencies in these markets.
About: Aadithya is a grad student who works with Prof. Jaijeet Roychowdhury (across the street in Cory Hall). He works on developing algorithms and software tools that are used by chip designers for modelling, analyzing, simulating, and verifying their large-scale designs. He has a Bachelor of Technology degree from the Indian Institute of Technology, Madras. He's interested in pretty much everything related to algorithms, data structures, discrete math, and programming. You can reach him at aadithya.ucb.sp2014.cs70@gmail.com.



Name: Chung-Wei Lin
Email: cwlin2014s@gmail.com
Office hour: by appointment
Discussion sections: Section 15 (TT 1-2pm, 85 Evans) and Section 16 (TT 2-3pm, B51 Hildebrand)
Research website: http://www.eecs.berkeley.edu/~cwlin/
Random fact: Chung-Wei was born in the year of the PIG...SAME as many students in this class (if you learn the modular arithmetic).
About: Chung-Wei Lin received the B.S. degree in computer science and the M.S. degree in electronics engineering from the National Taiwan University. He is currently a 5th-year Ph.D. student in the Department of Electrical Engineering and Computer Sciences. His research includes computer-aided design of integrated circuits and design automation of embedded systems. He was a summer intern of General Motors in 2011, 2012, and 2013. He was also a CS70 GSI in Spring 2013.

His current research is the security of embedded systems. For example, there was no security mechanism for in-vehicle or vehicle-to-vehicle communication, but it has become a big issue for vehicle companies now. How to authenticate or encrypt/decrypt a message and achieve these goals without generating too much computation or communication overhead? How to automatically design such a system and meet all requirements? All of these topics involve mathematical analysis, software design, and hardware implementation.

Random fact: Ian once broke both of his arms in one fall while snowboarding.
About: Ian is a 4th year undergraduate student in computer science, and I enjoy writing bios that alternate between the first and third person. CS70 was my favorite class, so Ian is very excited to TA! I enjoy playing music (guitar mostly), and I like creative writing (short stories mostly). He is also on jericho! the longform improv and sketch comedy group on campus. I spent this winter traveling in the midwest.



Name: Govind Ramnarayan
Email: cs70.govind@gmail.com
Office hour: Tuesdays 10-11am in Soda 611
Discussion sections: MW 9-10 AM, 75 Evans and TTh 9-10 AM, 105 Latimer
Random fact: Govind likes singing opera and jazz.
About: Govind is a 4th-year undergraduate pursuing a bachelor's degree in EECS and a minor in mathematics. He likes questions about the intrinsic hardness of problems and how information can help solve them (or fail to help solve them). For instance, if I asked you to retrieve a coin I hid somewhere in Berkeley, it would be very difficult to find it unless I told you exactly where it is. What if I told you where it was to within a block? Would you be able to find it then? What if I told you I threw it in the bay -- would any information I can give you help? He also enjoys exploring Berkeley restaurants and cooking.

Govind interned at Splunk in summer 2012 as a software engineer, writing and debugging test code.
