New Year’s resolution: more personal coding projects this year. Just finished pretraining and instruction fine tuning my own GPT2 scale LLM from scratch in PyTorch. Was so much fun!

It’s actually deep learning with a single weight layer, single output, linear unit, and squared loss. 😇

Our new paper "High-capacity associative memory in a quantum-optical spin glass." Achieves 7-fold increased capacity thru a quantum optical analog of short term plasticity from neuroscience. Atoms (neurons) couple to motion and photons (synapses)! arxiv.org/abs/2509.12202

Under Trump, NOAA ran the most recent competition for their highly prestigious postdoc program in climate and global change — but funded no one, wasting huge amounts of applicant and reviewer time. It gets a lot worse. Now current postdocs in the program are going unpaid.

"Senior officials at the US Department of Veterans Affairs have ordered that VA physicians and scientists not publish in medical journals or speak with the public without first seeking clearance from political appointees of Donald Trump, the Guardian has learned."

Exclusive: US veterans agency orders scientists not to publish in journals without clearance
Move that seeks political control of doctors’ and scientists’ published research fits a pattern of censorship by the Trump administration, veterans advocates say

OPT is the program that allows foreign students graduating with STEM degrees stay and work for up to three years. Because of the oversubscribed H-1B lottery, OPT is one of the main ways that foreign students manage to transition to jobs in the US. Ending it would destroy a major STEM pipeline.
