About Me:
I'm a fifth year graduate student in the MS/PhD programme in Computer Science, University of Massachusetts. My research interests are in Computer Vision and Machine Learning, focusing on fine-grained recognition, face recognition and deep learning. I am co-advised by Prof. Erik Learned-Miller and Prof. Subhransu Maji at the UMass Vision Lab. For my synthesis project, I have worked with Prof. Dan Sheldon on ecological computing.

I maintain the website for FDDB - a benchmark for detecting faces. I have been a reviewer for CVPR and the journals TPAMI and CVIU. At UMass I help organize the Machine Learning and Friends Lunch (MLFL) seminar series. Earlier, I was involved in GRiD, a multidisciplinary graduate student organisation for data science.

I have spent two happy summers in 2017 and 2014 interning at The Mathworks Inc. with the Computer Vision Toolbox team.

In the past I had worked on scene text detection and handwriting recognition at the Indian Statistical Institute, Kolkata. My mentors there had been Profs U Bhattacharya and SK Parui.
