Mehrdad Hessar

I work on machine learning model optimization on different hardware architectures at OctoML. I am a maintainer of Apache TVM project.
Before OctoML, I received my PhD in computer science and engineering in 2021 at Paul G. Allen school. I was a research assistant at Mobile Intelligence Lab working with Shyam Gollakota. I worked on low-power wireless networks and embedded devices for Internet of Things applications. I have experience in low-power backscatter communication, signal processing, hardware design, ML optimization and ML deployments.
I earned my M.Sc. in Electrical Engineering from ECE Department at University of Washington. Before coming to UW, I received my B.Sc in Computer Engineering from Amirkabir University of Technology.
