I am looking for faculty and research positions.
My CV, Research Statement, and Teaching Statement.
I am a Computer Engineering Ph.D. Student in the Department of Electrical and Computer Engineering at Rice University. I work with Professor Lin Zhong in the Rice Efficient Computing Group.
I received my M.Sc. from Rice University in 2008 and my B.Sc. in Computer Engineering from Sharif University of Technology in 2004. I have been a research intern with Deutsche Telekom R&D Lab USA, Motorola Labs and AT&T Labs Research in Spring 2010, Summer 2008, and Summer 2006, respectively.
I have led the design and implementation of the Rice Orbit Platform, an open source Bluetooth body area research platform for mobile computing and health applications.
My research interests fall within the general area of mobile computing. My research is focused on system solutions for energy efficient, usable, and context-aware mobile devices and services, including:
- Mobile, embedded, and wireless system design and applications
- Context-aware computing through sensing and statistical learning
- Pervasive health and biomedical applications
- Human factors and HCI
