Obsessed with vision and optics. Opinions (have many but share few) are my own and most posts are from my labs at The University of Waterloo (Canada) and UC Berkeley (USA). Oh...and that's my retina in the profile picture.

Congratulations @leahgjohnston.bsky.social for winning the @optica-fvm.bsky.social YIA!
Most #visionscience folks know that stabilized retinal images fade. Fewer know that stabilized, but flickering, images also fade. Even fewer know that the flicker-fading doesn't take place in the retina.

Congrats to this year’s Young Investigator Award winners #OpticaFVM! 🎉

Seems that a small earthquake knocked our #AOSLO #AOOCT system out of alignment. It may be time to engage to the air suspension.... One of the perils of doing research at #ucberkeley.

Hannah works hard every on her PhD, doing very cool #visionscience every day in my lab at #UCBerkeley. But does she go home and put up her feet every night? Nope! She is speed-puzzling phenom, heading to the world championship later this month. Go Hannah!
