Hi, I'm

Aias Tatsis

Electrical Engineering @ Harvard  |  Co-Founder @ Acaysia

Building adaptive control systems, simulation engines, and hardware that push boundaries.

About Me

I'm a student at Harvard University studying Electrical Engineering (B.S. expected 2029), with a background spanning adaptive ML control, embedded systems, computational fluid dynamics, and robotics.

As co-founder and technical lead at Acaysia, I build adaptive ML control algorithms for continuous-flow chemical reactors, digital-twin simulation frameworks, and hardware-in-the-loop control systems.

Previously, I led PiForce — a team that represented Greece at the Aramco F1 in Schools World Finals 2024, winning the Oracle Red Bull Racing Achievement Award. I've placed 3rd at EUCYS, 1st at Vodafone Generation Next, and received Gold at the FIRST Global Challenge.
