George Tzimpragos

About.

I am an Assistant Professor in the Electrical Engineering and Computer Science Department at the University of Michigan. My interests tend to sit within the field of computer architecture but are not limited to this area. For my latest updates, please take a look at my publications page and scholar profile.

My research is primarily guided by the following three questions:

1. How can we squeeze more performance and efficiency out of existing transistors?

2. How can we better leverage novel devices to perform useful computations?

3. How can we improve turnaround times and formally guarantee correctness? 

To this end, I follow a bottom-up approach and aim for cross-stack solutions that bridge circuits, computational logic, microarchitecture, and programming languages. I am also excited to be at the forefront of innovation in hybrid quantum-classical computing through my participation in the Midwest Quantum Collaboratory and the IEEE IRDS committee on Cryogenic Electronics and Quantum Information Processing.

Before joining the University of Michigan, I received my Ph.D. in Computer Science from UC Santa Barbara. My dissertation was on the development, formalization, and deployment of a neuro-inspired temporal paradigm for in-sensor processing and superconducting computing. Prior to that, I obtained my Master's degree in Electrical and Computer Engineering from UC Davis. My alma mater is the National Technical University of Athens in Greece. 

Recruiting.

I am actively looking for intellectually curious students. Please apply and reach out to me if interested!
