I am a PostDoc at Stanford (Autonomous System Lab) with Prof. Marco Pavone and UC Berkeley (BAIR) with Prof. Jitendra Malik. My research focuses on Learning Perception and Navigation for Legged Robots with a focus on training RL policies and Large Behaviour Models.
I obtained my Ph.D. in robotics at the Robotic Systems Lab at ETH Zurich and the Max Planck Institute for Intelligent Systems, co-advised by Prof. Marco Hutter and Prof. Georg Martius. During my Ph.D. I joined NASA’s Jet Propulsion Laboratory as a visiting researcher and continuously collaborate with the Dynamic Robotic Systems Group by Prof. Maurice Fallon at University of Oxford. I worked as a Collaborative Robotics Engineer at SEW-Eurodrive before starting my Master’s in Robotics Systems and Control at ETH Zurich. Throughout my Master’s I was supervised by Prof. Roland Siegwart and spent most of my time at the Autonomous Systems Lab. During my Bachelor’s, I worked at the chair for High Performance Humanoid Technologies with Prof. Tamim Asfour (KIT, Germany) and conducted my Bachelor’s Thesis with Prof. Takamitsu Matsubara in Japan (NAIST, Japan).

Our paper “Resilient Legged Local Navigation: Learning to Traverse with Compromised Perception End-to-End,” has been nominated for the Best Paper Award for ICRA2024! Key Insights:
Unreliable Perception Systems: It’s impossible to always guarantee the reliability of perception systems.
Need for Advanced Planning: There is a critical need for planners that can detect failures in perception systems and react appropriately.
Use of Proprioceptive Data: Detecting these failures is feasible through the use of proprioceptive data.
Limitations of Traditional Methods: Classical planning methods often fail to utilize such data effectively, prompting the need for innovative solutions.
Using RL to Discover Emerging Navigation Strategies: Rather than relying on handcrafted heuristics, we use reinforcement learning (RL) and expose the robot to an environment with various types of perception failures. Our asymmetric actor-critic framework discovers emerging navigation strategies.
