I had the great honor of serving as an opponent for Lari Virtanen’s PhD defense on Friday at the University of Helsinki. Lari isn’t on bsky, but check out his papers on ensemble perception and color that show just how flexible and efficient it is! researchportal.helsinki.fi/en/persons/l...

Today, the PhD student I co-supervised with Dr. Toni Saarela, Lari Virtanen, is defending his thesis on color ensemble perception at the University of Helsinki. It is both a happy and a sad day. Toni passed away only two weeks ago and just missed seeing his first PhD student graduate. RIP Toni ❤️😔

I’m absolutely fascinated by the late 19th century Austrian artist Marianne Stokes and am embarrassed to admit I only saw her art now at the Gothic Modern exhibition in the Finnish national gallery. Her use of red gives me chills.

I like how the perception of 3D structure in this starts and ends strong while devolving into interesting chaos in the middle. #VisionScience
