Can we use the scattering of light to perform computation?

Our new paper maps three design axes for optical reservoir computing, finds peak memory at the edge of chaos, and demonstrates 84.5% spoken-digit accuracy.

논문 쓸 때 알았더라면 좋았을 것들 is selected as a 2026 Sejong Book.

A year old, 4th printing, and the first title to sell out at the KAIST shop.

Everything I wish I'd known about writing papers — write the conclusion first, design figures before text Grateful it's been useful.

Embryo selection today rests on 2D morphology and the embryologist's eye. #Holotomography lets us measure refractive index — and therefore dry mass — in 3D, in living oocytes and embryos, without labels or fixation.
