🧪 Applied gradient descent to gold nanorod and spectroscopy!

Decomposing UV/Vis absorption into basis functions reveals size distributions with banana-shaped correlations between length/diameter.

Just wrote about working with experimental data in Python.

Used real quantum simulation data to show three ways to structure experimental grids.

When you have 50 expensive nanoparticle spectra instead of 50,000 cat photos, what do you do?

Suddenly understanding distributions and uncertainty quantification isn't optional. Math matters in scientific machine learning.

I'm 3 weeks into figuring out: "can machine learning + analytical chemistry impact biotech?"

Going through #spectroscopy data from a paper. Messy as usual.

UV/Vis spectroscopy + 30 experiments + Extra Trees = predicting gold nanoparticle shapes

Sometimes small data + domain knowledge beats big data + brute force

💰 The $2M question in nanoparticle QC: How do you get TEM-quality data without TEM costs?

Today's deep dive revealed why this matters for biotech. 🧵

Why study as ML person?

The next biotech revolution won't come from better models alone—it'll come from ML that designs & interprets experiments.

Writing diagrams as code with Tikz becomes so much easier with Claude.

And it still takes a lot of time...

Ai4bio conference in delft covered all scales in biotech. Impossible to summarize, this slide comes closest.

I drew this diagram today of a bioreactor.

In Tikz.

Training models on GPU's feels like playing simultaneous chess: tweak, try, abort, repeat — across 5 boards.

in this post, I share the system monitoring tools that give me instant feedback, so I can spot bottlenecks fast.
