PROFESSIONAL EXPERIENCE

Johns Hopkins University Baltimore, MD

Research Assistant, eScience & Sensor Networks Group Aug 2007 - present

Timestamping algorithms: Developed two energy-efficient algorithms to assign timestamps to sensor

measurements. Developed in Java.

- Resulted in 10% increase in data yield and enabled networks to operate unattended for months.

- Implemented a sensor network simulator to understand scalability of the solution.

Environmental data management: Designed and implemented a multi-stage end-to-end data processing

pipeline for sensor data streams in Transact-SQL and C#

- Current Size: 100 Million+ records.

Analytics of network logs: Analyzed and improved the performance of a wireless sensor network based on

network logs

- Identified failures causes, metrics and performed statistical analysis to predict failures of components.

Sensor data visualization: Designed a system to visualize real-time, multi-resolution environmental data

collected by the JHU soil sensor network.

- Used by the LifeUnderYourFeet soil-ecology group at the Johns Hopkins University.

- Mentored two masters and two undergraduate students.

Data-driven data collection: Improving the data collection system by exploring the tradeoff between

communication costs and fidelity using robust statistical methods.

- Developed an incremental and robust principal component analysis (PCA) library in MATLAB.

PROFESSIONAL EXPERIENCE (CONTINUED)

Microsoft Research San Francisco, CA

Research Intern, Scalable Servers & eScience Group Jun 2007 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.

- Used by the AmeriFlux scientific collaboration.

Inter-University Centre for Astronomy and Astrophysics Pune, India

Project Officer, Virtual Observatory Project Jun 2003 Aug 2005

Telescope data archiving: Part of a team of five that designed an archival system for data generated from

optical telescopes. Developed in Java

Data exploration of astronomy surveys: Employed SQL query plans to retrieve data for analytics of the Sloan

Digital Sky Survey database (~ Tb)
