About me
I am a PhD student in the Advanced Interactive Technologies lab at ETH Zurich under the supervision of Prof. Otmar Hilliges. I received my BSc (2016) and MSc (2018) in Electrical Engineering and Information Technology from ETH Zürich with a focus on robotics, machine learning and control.
Research Interests
My research focuses on modeling human interactions with the physical world. Specifically, I'm researching how natural and physically plausible behavior can be integrated into generative motion models by using physics simulations and deep reinforcement learning. Furthermore, I'm investigating how these models can be leveraged in application domains such as human-robot Interactions, AR/VR, and others.
You can also find me on Twitter, Linkedin, and Google scholar.
