Okay, long-overdue introduction. I’m a computational neuroscientist at Duke, where my lab (pearsonlab.github.io) does theory “bottom up”: we try to start by modeling data and build toward principles.

For about ten years I've thought about what a Tom Waits TV Christmas special produced in the early 80s would have been like. It's almost real to me. The set is a Depression-era shack he built and a stream of celebrity hobos keep knocking on the door and Tom goes "I wOnDEr WHo tHaT cOuLd bE"

Development of the primate projection-targeting opto methods was supported in part through a DIBS Germinator award to the incredibly talented Dr. Bohlen.

Beautiful work on a frontal cortex to brainstem pathway in the primate brain, from NEI intramural investigators with help from Martin Bohlen and others in the Sommer Lab at Duke! Optogenetics for projection targeting and causal manipulation, to study visuomotor behavior.

Do you love quantifying animal behavior as much as we do? We have just the tool for you! Presenting #OCTRON - a pipeline that helps you create rich annotation data and enables training of custom segmentation models. Have a look, particularly if you work with non-model / invertebrate organisms!

The UNC system just released its final policy on mandatory syllabi disclosure, stating that syllabi are university (not faculty) IP and certain course info must be posted on new, publicly searchable databases before every semester.

A thread about what's changed from the draft I reported on earlier:
NEW: Public universities in red states, from Texas to Florida, are increasingly required to make their syllabi public. The University of North Carolina may be next. Does "syllabi transparency" help combat distrust in higher ed, or feed ill-informed suspicions of it? www.chronicle.com/article/when...
When Everyone Can See Your Syllabus
More states are requiring public colleges to make class syllabi available to the masses. Proponents say these measures boost higher ed’s credibility, while faculty fear being targeted.

Grateful to @pewtrusts.org for funding our snow fly work, in collaboration with Sebastian Brauchi at Universidad Austral de Chile.

We are now looking for post-docs to work on the biophysical mechanisms that allow snow fly neurons and muscles to function below zero.

We took a stab at how to infer both the dynamics and control parameters of partially-observable systems.

It’s a nasty problem, but @vgeadah.bsky.social made tremendous progress, ending up with some really elegant formalisms.
In a system subject to unobserved control, can you infer both the underlying dynamics and the control objective? 🤔

A year ago, I was presenting our work at IEEE CDC on solving this problem for stochastic LQR.
arxiv.org/abs/2502.15014

Short 🧵 on the results, and how I think about them a year later.

Honestly, I couldn't say -- I'm hardly an expert in pre-whitening.

Luckily, Mandy Mejia is a co-author on the paper (and also wrote this awesome blogpost, like, 10 years ago).

We basically followed her approach as close as possible.
