Humanoids on campus! Check out our new work on context-aware locomotion.
our new system trains humanoid robots using data from cell phone videos, enabling skills such as climbing stairs and sitting on chairs in a single policy. (w/ @redstone_hong @junyi42 @davidrmcall)

RDM is now published at Nature Methods! This was a 3 year effort and my introduction to academic research. I’m fortunate to have been mentored by one of the smartest people I’ve ever met @the_legitamit!.
Ring deconvolution microscopy is now published at @naturemethods! . There are some fun new additions including light-sheet deconvolution 🫡. Stay tuned for the official python package release next week! Any feature suggestions are more than welcome 😃.
