Summary

Computational materials scientist with a strong background in research and industrial software engineering and a keen interest in leveraging the predictive capability of molecular scale materials modeling at an industrial scale with the goal of reducing manufacturing cost and improving materials performance. I am looking forward to challenging positions that takes advantage of my skills.

Work experience

Jun 2019Present

Modeling Engineer, Integrated Materials Engineering & Technology (IMET), Drug Product Development

Celgene Corporation, Summit, NJ, USA
  • Developed data ingestion pipelines for collecting data from materials profiling experiments as well as simulations into data lake
  • Developed analysis methods for computational fluid dynamics models of drug development processes such as fluidized bed drying and mixing tanks
  • Developed strategy for modeling molecular scale phenomena in drug development

Post Doctoral Research Associate

University of Tennessee at Knoxville
  • Preparing molecular dynamics (MD) simulations for the exascale (10^18 FLOPS) computing machines of the future. This is achieved by developing tools that mitigate the issue of MD simulations producing data at a higher rate than it can be written to disk for analysis as a result of the dichotomy in the rate at which FLOPS and I/O OPS capability of high-performance computers is growing. These tools allow in-situ analysis of the MD data at a higher resolution than was possible using traditional post-hoc analysis and saving only necessary data that will be required for further analysis or for continuing simulations
  • Responsible for coordinating an NSF funded multi-university collaborative project (analytics4md.org)

Graduate Assistant

Boise State University
  • Developed CUDA capable coarse grained molecular simulations of epoxy resin cure in collaboration with Boeing Research and Technology. Using this model, 2 million particle simulations in cubic volumes of side length 100 nm  can reach 95 % curing in under 10 hours of compute time. This level of computational performance is key to being able to do ensemble averaging and represents the state-of-the-art of polymerization models
  • Improved the performance of the a concrete micro structure model called "Anm" by a factor of 5 using thread parallelization. This enabled the creation of highly densely packed virtual cement models which led to the quantification of the structure of cement particles around irregular shaped aggregates for the first time

Senior Systems Specialist

General Electric Company, Bangalore, India
  • Developed a new thin client-based assay development framework for a confocal high content analysis instrument (HCA) used in life sciences which vastly improved the accessibility of the legacy platform
  • Conducted Scrum methodology training for over 35 team members to aid the team transition from a waterfall model of software development to the Agile model
Oct 2008May 2010

Senior Software Engineer

Sasken Communication Technologies, Bangalore, India
  • Achieved 80%+ automation of the test cases for the Bluetooth stack on the Nokia S40 series mobile phones. This drastically reduced the manual test effort and increased productivity by 50%
  • Identified and designed effective test cases for Bluetooth Low Energy (BTLE) specifications
Aug 2004Oct 2008

Senior Software Engineer

Microview Technologies Pte Ltd, Singapore
  • Developed hardware interfacing components for industrial cameras, servo motors and high speed I/O cards for a graphical programming framework which enabled the rapid development and deployment of machine vision applications for inspecting fasteners and image sensors
  • Implemented an extremely reliable machine vision-based measurement tool for the fastener industry using the six sigma Gage Repeatability and Reproducibility  (GRR) method
  • Optimized the garbage collection mechanism to keep the cycle time to be reliably under 60 ms for the fastener inspection system
