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.

Hey @thorlabs.bsky.social, where are my snacks? Is it because I'm in 🇨🇦?

🇨🇦 This sign calls to me every morning on my commute to @uwaterloo.ca. Question is: blow off work and head west to Lake Cowichan BC or east to Cappahayden NFLD? @transcanadatrail.bsky.social

Spotted this morning outside of the stunning Daniels Building at the University of Toronto, where I'm attending @iccp-conference.bsky.social. Nothing computational here, just a regular photo.
Super excited to see the hawk...but that rat is huuuge!

Lots of room for growth at @uwaterloo.ca. 🇨🇦 And were hiring 6 new faculty in #optometry and #visionscience. Spread the news. Contact me if you want to learn more.

Some things are new (the Instagram-worthy sign) and some things are old (the iconic Dana Porter Library, where I spent many hours as a physics undergrad in the late 80s). @uwaterloo.ca 🇨🇦

While many of you may suffer FOMO for #OLO, we folks in the lab suffer FOMO for YOLO. That was the case until Stuart Semple graciously sent us some free bottles. What this all about? Check out

Thanks!!!

Thanks to @ucobservatories.bsky.social for the fun and informative 'insider' tour of the @lickobservatory.bsky.social for me, my former students and postdocs, and colleagues. Special thanks to @elinorgates.bsky.social, resident astronomer extraordinaire and ultimate tour guide for her time.

Oddly, PhDs at @ucberkeleyofficial.bsky.social don't require public defenses - we just need 3 committee members to unceremoniously sign off. To make up, we hold an annual symposium, where families, friends, faculty and students attend. Congrats Max Greene and Stephanie Reeves for outstanding talks.

Such an honor for me to receive this award named after Bob Boynton, who I never knew, but whose approach to science was an inspiration for me. His son just happened to attending #VSS2025 when the award was announced. The apple does not fall far from the tree.

Most years at ARVO, I award the Picture of the Year, or #POTY prize. This year it goes to
Toco Chui
of the New York Eye and Ear Infirmary
for her presentation titled
"In-vivo imaging of blood cell adhesion to vascular wall in sickle cell disease"

Hard to believe that #visionscience PhD student Jason Wong is still smiling (let alone standing) after holding court for hours at his first #ARVO2025 poster, co-authored with @shangbangluo.bsky.social

As one of the subjects in this study, I can tell you that the closest natural color to 'olo' is achieved by mixing two parts #Midori and one part #BlueCuracau. Not sure what those are? Just reach to the back of your parent's liquor cabinet, it'll be beside the Galliano.

You know your wife loves you when she installs tile in your new shower that looks like a foveal cone mosaic. (but not enough to make them colored red, green and blue). #visionscience #adaptiveoptics

Just had a memorable visit with living legend Gerald Westheimer as he approaches his 101st birthday. We talked about his latest hobbies: using ChatGPT to craft Matlab code for convoluting complex pupil functions, and quantum optics. @ucberkeleyofficial.bsky.social #visionscience

Many of my favorite things captured here.... Optics, biking and 🏀. Taken on my ride back to Berkekey from patient imaging at UCSF ophthalmology.
