My primary area of research is medical image analysis, focusing on brain image analysis. Other research interests include deep learning, survival prediction, object segmentation. 

EXPERIENCE

Sep 2020 -  

Post-doctoral Fellow

National Institutes of Health Clinical Center

Working on identifying post-surgical language deficits in epileptic patients using statistical machine learning approaches.

July 2019 - July 2020 

Pre-doctoral Fellow

National Institutes of Health Clinical Center

Worked on identifying functional differences in epilepsy patients using task based fMRI.

Oct 2014 - July 2015

Internship

GroboMac

Developed an algorithm to detect cotton in farms. Constructed a stereo-vision setup to return the position of the detected cotton for a robotic arm to extract in real-time. 

Jun 2014 - Sep 2014

Internship

Kaybus

Worked to develop a text detection algorithm for Document Images. We developed an algorithm to detect Text lines using Haar DWT and used Tesseract OCR to extract the text from the image. Also tested HOG based approach to detect text lines in images.

Sep 2012 - Aug 2013

Research Assistant

Rensselaer Polytechnic Institute

1. Worked with Dr. John W. Woods to develop a Rate Allocation Algorithm for MDFEC. In this project we developed an algorithm to optimize non-convex SVC encoder data for optimal rate allocation.

2. Worked on National Science Foundation (NSF) Grant CNS - 1018398, "NeTS : Flexible Delivery of Streaming Video using Network-Aware MD-FEC Coding.
