About Me

I am a PhD candidate in Computer Science at the Ohio State University (started in 2014), and I am being advised by Prof. Rajiv Ramnath, Prof. Arnab Nandi, and also Prof. Srinivasan Parthasarathy. I am also a research scientist at the Nationwide Insurance, and a member of Enterprise Data Office (EDO). My research interest is on applied machine learning and data mining, where I enjoy developing and applying advanced models to address a variety of challenges in application domains such as telematics and transportation, spatiotemporal data mining, user behavior study, question-answering systems, and natural language processing. I also have a master in Computer Software Engineering from University of Tehran, advised by Prof. Maseud Rahgozar (Tehran, Iran 2012), and a bachelor in Computer Science from Shahid Beheshti University (Tehran, Iran 2009).
