Submitted.
Work Experience:
* Sept 1998 - Present:

Research Assistant, CSD, Stanford.

Advisor: Serge Plotkin.

The main focus of my work has been the design of approximation and online algorithms for problems arising in data networks and in clustering. The publications are listed above.


* January-May 2002:

Consultant, Strand Genomics, Bangalore, India.

Manager: Dr. Ramesh Hariharan.

Developed general purpose clustering and statistical relevance tools for large scale medical informatics applications. In particular, performed statistical analysis of time-series and microarray image data, and clustering of molecular structure data in a drug database.


* January-April 2002:

Instructor, Dept. of Computer Science and Automation, Indian Institute of Science, Bangalore

Taught a complete graduate level course titled EO325: "Topics in Algorithms" to a class of 16 students. The focus of the course was Approximation Algorithms for NP-Hard problems and algorithms with low space complexity. It involved 3 hours of lecturing a week for a whole semester. The Indian Institute of Science is a premier research institute. The course web page is at http://theory.stanford.edu/~kamesh/iisc.html
* Summer 2001:

Intern, Mathematical Sciences Division, IBM Thomas J Watson Research Center.

Mentor: Baruch Schieber.

Analysis of a simple greedy scheme for online buffer management in a shared memory output queued switch. Improved the existing upper and lower bounds for special cases of this problem.


* Summer 2000:

Intern, Math of Networks and Systems group, Bell Labs, Murray Hill, NJ.

Mentor: Matthew Andrews.

Designed a fast and scalable packet switch scheduling algorithm for a new type of scheduling problem. Instead of scheduling packet by packet, the scheduler collects packets in an "envelope" and schedules them at once. Did extensive simulations of the algorithm as well as an implementation in Verilog HDL. It was shown by simulation that the algorithm is very good in terms of stability and delays, and that the algorithm can be implemented to work very fast in hardware.

* Summer 1999:

Intern, Math of Networks and Systems group, Bell Labs, Murray Hill.

Mentor: Matthew Andrews.

Worked on two separate problems related to computer networks. In the first problem, we designed a new algorithm for caching when the data to be cached is a multimedia clip requested by many users. The requests made by the users are temporally different, but the content to be served is the same. We show near optimal competitiveness. Work appeared in ESA '00. In the second problem, we designed placement and load balancing algorithms for the Lucent IPWorX web caching system.


* 1997-98:

Senior Thesis, IIT Bombay.

Advisor: Abhiram Ranade.

Worked on external memory graph algorithms. Showed improved upper bounds for graph connectivity, and came up with a simple implementation of BFS in external memory. We also presented the first known lower bounds in a slightly restricted model of computation. Work appeared in SODA '99.


* Spring 1997:

Junior Term Paper, IIT Bombay.

Advisors: Ketan Mulmuley and Sundar Vishwanathan.

Presented a home paper titled McMullen's Conditions for Simple Polytopes, which starts with a study of the basic combinatorial properties of polytopes, and then goes into McMullen's Conditions, the proof of their sufficiency, and the Polytope Algebra.


Programming Projects:


  • Design and Implementation of a switch scheduler for an input queued switch in Verilog HDL, with simulation and timing analysis (joint work with Matthew Andrews)

  • Application layer implementation of the greedy algorithm for constructing multicast trees for the Stanford WebBase. (Joint work with Ashish Goel)

  • Compiler for a subset of Pascal using C, Lex and Yacc. The output was SPARC assembly code.

  • Design and implementation of a RS232 serial receiver in hardware.

  • Interpreter for a subset of VHDL using compiler generation tools.

  • Design of a signed 8-bit multiplier using VHDL, implementation on an FPGA, and interfacing with an 8085.

  • Game of anti chess in Pascal, using techniques from A.I.


Languages:
C, C++, Perl, SQL, Verilog, VHDL.
