About Me
I am a Senior Research Scientist at Snap. My work spans the data mining, machine learning, and computational social science domains, specifically in the contexts of understanding and modeling user behavior and misbehavior on social platforms.
Before I joined Snap, I defended my PhD thesis in the Computer Science Department at Carnegie Mellon University, where I worked on discovering and modeling various types of abusive online behaviors as anomaly detection problems in large networks. I was very fortunate to have been advised by Christos Faloutsos.
Prior to this, I received my B.S. in Computer Science from the Department of Computer Science at North Carolina State University. There, I worked with Nagiza Samatova on reduction, indexing and storage systems for large-scale scientific data.
If you would like to learn more about my work, take a look at my publications and CV.
