I am a 4th year PhD student in Electrical Engineering and Computer Science at the University of California, Merced.
Currrently, I am investigating on spatial representation techniques for 3D Path planning and Visualization of various navigation metrics under the supervision of Professor Marcelo Kallmann. Apart from Path planning and spatial representation,
I am also working on improving path following behavior for Multi-agents and Autonomous Crowds. Prior
to joining at UC Merced, I worked as Senior Graphics Programmer at Passur Aerospace Inc. I holds a
master's degree in Computer Science from the school of Electrical Engineering and Computer Science
at Oregon State University where I was advised by
Professor Eugene Zhang. The title of my master's thesis was "Interactive Design and Transition Point Analysis
of 3D Linear Symmetric Tensor Fields". My areas of interest are Computer Graphics, Animation, Robotics Algorithms,
Geometry Processing, Computational Geometry and Scientific Visualization.

Interactive Design and Transition Point Analysis of 3D Linear Symmetric Tensor Fields
3D symmetric tensor fields have a wide range of applications, such as in solid and fluid mechanics, medical imaging, meteorology, molecular dynamics, geophysics and computer graphics. There has been much research carried out in this field, yet our knowledge of the tensor field is still at its initial stage to completely understand the behavior of 3D linear tensor fields. To understand the behavior and to design such applications, topology plays an important role. The degenerate points are the most studied topological feature of symmetric tensor fields. Though several attempts have been made to understand such features, still none of them seems to be complete. In this work, we provide an interactive interface to study such features. We also study the maximum number of transition points in a linear tensor field and classification of wedge and trisector along the degenerate curves. Finally, we provide an insight over the upper and lower bound on the number of transition points in a linear tensor field. This work is also a part of my MS thesis.

RendermanLink: Interface between Wolfram's Mathematica and Pixar's Renderman
In this project, I built a software package in C to connect Wolfram's Mathematica with Pixar's Renderman.The main aim of this project is to utilize the rendering power of Renderman Engine to produce a high resolution images without being concerned with the syntax used for Renderman API ie., the user with just a knowledge of Wolfram Language can generate high resolution images in no time. This work was part of my internship at Wolfram Research Inc. in their Mathematica Algorithm R&D department.

Result |
Unsignalized T-intersection Simulation
In this project, we (Ankita Chaudhary and I worked under the supervision of Professor Gopal R. Patil) created a simulation to showcase the actual movement of vehicle on an unsignalized T-Intersection using Cellular Automata technique. This simulaton serves the purpose of training student (pursuing transportation engineering) for an actual survey or data collection.
