CS 348A - Geometric Modeling: Planning Helicoptor Tours Over Terrain:
o Implemented a simulator in Open GL to build a triangulated irregular network(TIN) of geographical terrains.
o Desgined algorithms for planning smooth sight-seeing tours by flying over these terrains; optimizing the three constraints - length, curvature and the 'safeness' of the path.
o Provided ability for modification of tour points and detours.

Undergraduate Research Experience
Design and Implementation of e-learning modules
Pilani, IndiaGuide: Dr. Rahul Banerjee, Associate Professor, CSIS Group, BITS-Pilani
Aug 2007 - May 2008
o Prepared a technical report on OpenMP and MPI programming for shared memory processors which laid the technical groundwork for IPv6 enabled iCharak Health Grid project.
o Developed a web based interface for a stock market simulator with a built-in Really Simple Syndication (RSS) reader.
o The simulator was developed using JavaScript, Java Servlets (in jdk 1.5.0.04) and HTML (integrated using the NetBeans 5.5 IDE) as the front end and MySQL as the backend database.
o The RSS reader uses XML and DOM functions of PHP for reading and displaying RSS/Atom feed in a suitable GUI.
