Assistant Professor, Elmore Family School of Electrical and Computer Engineering
Courtesy Appointment, School of Mechanical Engineering
Purdue University, USA

Personal website

Johannes Lachner's research focuses on geometric methods for robot control and manipulation, including task-space control on Lie groups, geometric fabrics, and structured optimization for compliant physical interaction.

Tobias Löw
Dr. Tobias Löw Confirmed
Postdoctoral Researcher, University of Washington, USA
Personal website

Tobias Löw is a postdoctoral scholar advised by Prof. Siddhartha Srinivasa at the Personal Robotics Lab at the University of Washington. His research focuses on geometric representations for robotics, with the goal of enabling robots to better perceive, interact with, and adapt to complex human-centered environments. His work explores how geometry can support efficient computation, safe interaction, and scalable generalization across robotic tasks.
