Education

Ph.D. Candidate, Bioinformatics and Algorithm Optimization, January 2004 - November 2007

• Dissertation Topic: “Computational Methods For Phylogenetic Analysis”

• Advisor: Dr. R. C. Joshi and Dr. Ankush Mittal

Summary: Phylogenetics is the study of relationship among species or genes with the combina-

tion of molecular biology and mathematics. In this research work we tried to find relationships

between species with application of pattern recognition methods. We applied and improved dif-

ferent pattern recognition algorithms to solve different phytogenetic and computational biology

problems. Computational and memory efficiency of the algorithm for large scale data was con-

sidered as metric for evaluating existing and newly developed algorithms.

As a result of this research we solved four different phytogenetic related problems using efficient

refactoring of pattern recognition algorithms. These algorithms and methods shown superiority

over existing algorithms both in terms of computational efficiency and memory usage. The results

were also evaluated by biotechnologists’ for their biological significance. IBM awarded this work

as best PhD research work in 2006.

• Dissertation and Project: “Data Extraction Software For Telemetry Systems”

• Advisor: Dr. Vijay Kumar

Summary: Data collection and analysis from a far away station has became a key component

of many latest technologies, like Nuclear Power Plants, Super Fast Plane and millitary systems.

Measuring and doing analysis of data collected from a far away station or device is known as

telemetry systems. These are one of the most useful component to measure performance of

systems where either human interaction and presence is impossible or harmful.

In the dissertation and project we designed and developed a system for collecting data from a

launched vehicle like satellite launches and analyze the data received from various senors placed

on satellite that communicate with ground station.

The challenging task was to receive and analyze represent fast receiving data from a launched

satellite. We developed a concurrent real time system that does the disced task accurately with

the help of distributed computer clusters.

This project was awarded the best M.Tech project of year in 2003.

Experience

age reconstruction algorithms focusing on MRI and CT. We developed and implemented few fastest

medical image reconstruction and processing algorithms using GPUs and FPGAs.

new features, porting the software to target devices and testing.

Recent Projects MRI Parallel Image Reconstruction Algorithms

Project: This project is focused on developing parallel techniques to speedup medical image recon-

struction for Parallel MRI Algorithms such as GRAPPA, SENSE and its variants. I was responsible

for data design, developing parallel algorithms on GPU, implementing and profiling them. It is a

joyful experience to make fastest applications in the world using the latest technology. We got over

100 times to 250 times faster results compared to serial implementation on few algorithms.

As an ongoing effort, I am responsible for the development of parallel algorithms for different algo-

rithms and benchmark them to deliver commercially competing products to deploy in the market.

Non Cartesian Image Reconstruction

Project: This project is focused on implementing a different Kernels for non cartesian Image Re-

construction. We applied Kaiser Bessel Kernel for converging Non Cartesian acquired data (radial

and spiral) to Cartesian. We proposed and developed a GPU based approach to achieve acceptable

computation time for 50000 arms on multichannel data.

Team Size: 3

PS Color Small Memory Emulation

Project: Supporting whole PS emulation in 13.5MB is big challenge, because normally printers

support emulation in 64MB of memory. We conducted a memory profiling of test files to figure

out the modules that are expensive in terms of memory. As Image processing module is major

memory consumer, we focused on its code refactoring and reengineering. We also used compression

and decompression to reduce memory. To avoid computational overhead of compression we took

advantage of hardware feature available in processor.
