George Tzimpragos

About.

I am an Assistant Professor in the Electrical Engineering and Computer Science Department at the University of Michigan. My interests sit within the field of computer architecture, which I see as a bridge between disparate domains. For my latest updates, please take a look at my publications page and scholar profile.

My current research activities are primarily guided by the following three questions:

1. How can we squeeze more performance and efficiency out of existing transistors, particularly in the context of sensor computing?

2. How can we perform useful computations with devices, such as superconducting and photonic, that break the established abstractions for CMOS?

3. How can we bridge the semantic gap between computation and verification operators to improve turnaround times and formally guarantee correctness? 

To this end, I follow a bottom-up approach and aim for cross-stack solutions that connect 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 University of Michigan's Quantum Research Institute, 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! Students with a strong physics background are also encouraged to explore the University of Michigan's Applied Physics Program, with which I am affiliated.
