I am a postdoctoral researcher at Stanford University, working with Prof. Jure Leskovec. I research on data science and machine learning for cybersafety and deception on the web and real world. In my research, I design an end-to-end research methodology to make the web better, safer, and more inclusive by studying malicious behavior, deception, and disinformation (e.g., sockpuppets, fake reviewers, hoaxes, and lying):
(1) I develop novel graph mining and deep learning models that can leverage graph-structured social datasets at a scale of billions of interactions among millions of entities to predict covert and complex malicious users and groups, and
(2) I deploy my methods to make fundamental scientific discoveries that have advanced our scientific understanding of cybersafety and have led to new tools of high impact, being used in production at Flipkart, Reddit, and Wikipedia.
My PhD dissertation (Computer Science, University of Maryland) was awarded the prestigious 2018 ACM SIGKDD Doctoral Dissertation Award runner-up and Larry S. Davis Doctoral Dissertation Award. Prior to that, I was awarded Dr. BC Roy Gold Medal by IIT, Kharagpur.
NEW! Thrilled to recieve the 2018 ACM SIGKDD Doctoral Dissertation Award runner-up!
