Implemented an incremental and robust principal component analysis library in MATLAB. * Timestamp reconstruction algorithms: Collaborated with Microsoft and University of Sao Paolo to develop two energy-efficient algorithms to assign timestamps to sensor measurements : Published (2009, 2010). Resulted in 10% increase in data yield and enabled networks to operate unattended for months. Implemented a sensor network simulator in Java to understand scalability of the solution. Used robust linear regression to estimate clock skews and offsets * Environmental data management: Designed and implemented an end-to-end processing pipeline for sensor network data streams in Transact-SQL and C# : Published (2008). Current Size: 100 Million+ records. * Anomaly detection in sensor networks: Researched statistical challenges and tradeoffs of simultaneous fault-detection and event-detection in environmental networks : Published (2008, 2007). Modeled and reduced datasets in MATLAB using principal component analysis (PCA). * Identified and characterized factors affecting sensor network lifetimes using system logs : Article under review. * Sensor data visualization: Designed a system to access and visualize real-time, multi-resolution environmental data and metadata collected by the Johns Hopkins soil sensor network. Used by the LifeUnderYourFeet soil-ecology group at the Johns Hopkins University. Mentored two masters and two undergraduate students. + Microsoft Research, San Francisco, CA --------------------------------------- - Research Intern, Scalable Servers & eScience Group, Jun 2007 to Aug 2007 * Matlab access to DataCube: Implemented a data adapter and MDX query builder in MATLAB to access data from a remote SQL Analysis Server : Published (2008). Used by the AmeriFlux scientific collaboration. + Inter-University Centre for Astronomy and Astrophysics, Pune, India --------------------------------------------------------------------- - Project Officer, Virtual Observatory Project, Jun 2003 to Aug 2005 * Telescope data archiving: Part of a team of five that designed an archival system for data generated from optical telescopes. Data exploration of astronomy surveys: Used SQL to explore the Sloan Digital Sky Survey database (~ Tb) : Published (2009).
