About Me

I am a Research Scientist at Lyft, where I work on routing and travel time estimation. Previously, I was a PhD student in Computer Science at Ohio State University, and was advised by Prof. Rajiv Ramnath, Prof. Srinivasan Parthasarathy, and also Prof. Arnab Nandi (Columbus, Ohio 2019). My research interests are 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’s degree 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).
