Visual Computing and Artificial Intelligence
|
|
I am a Senior Research Scientist at Adobe Research. Prior to joining Adobe I was Researcher and Software Engineer in the Google AI (Robotics at Google) team and a
Visiting Assistant Professor in the Geometry Lab of the Computer Science Department at Stanford University,
supported by the MPC-VCC and the SAIL-Toyota Center for AI Research.
I received my PhD from the University of Konstanz ( Visual Computing Lab), Germany.
My research interests are in Visual Computing and Artificial Intelligence with a focus on time-variant phenomena and multi-modal data streams.
Specifically, I am interested in developing efficient geometric representations to enable solving complex tasks like interactively simulating natural phenomena, encoding interactions and behavior, or for 4D computer vision.
In the past I have worked on topics such as understanding physical interactions, robotic manipulation and social navigation, learning from demonstration, style transfer, and video prediction.
I was recently invited by the ACM to chat about research on environmental modeling. The interview is available here: link.
