I am a software engineer at Google specializing in machine learning. I have received my doctoral degree in Computer Science from the Arizona State University in December 2019. I hold B.Sc. (2012) and M.Sc. (2014) degrees in Computer Science from the Middle East Technical University. I have been a Visiting Research Assistant at the Machine INtelligence and Data Science (MINDS) research group in University of Southern California's Information Sciences Institute (2018) and an undergraduate summer intern at the McKeown Group in the Department of Computer Science of Stanford University (2010).

My research is at the intersection of Machine Learning and Graph Mining, particularly their applications to Online Political Networks, Financial Fraud Management, Social Media Mining, Spatio-Temporal Pattern Mining.
