Razvan-Andrei Lascu

I am a Postdoctoral Researcher in the Deep Learning Theory team at RIKEN AIP. My research lies at the interface of Gradient Flows, Optimal Transport, Optimization and Reinforcement Learning.

I was previously a PhD student at Heriot-Watt University and University of Edinburgh, supervised by Mateusz Majka and Lukasz Szpruch.
