Five years of mechanical engineering, machine learning, and a team in Buenos Aires went into the machine running behind Jean-Christophe Quillet at BIO 2026. #BIO2026

Bubble-free laminar flow. Multiple independent processes. Simultaneous production. No impellers, no spargers, no shear damage to your cells. Continuous harvesting. The real thing on a benchtop. We have four days and one machine. If you want a demo, book ahead.

If you work in bioprocess development, cell therapy, or biologics manufacturing, and you've been wondering what continuous, laminar flow-based, shear stress-free bioprocessing actually looks like in practice, this is your chance to see it running.

We're bringing something new to BIO International Convention 2026. Juan Martin Cabaleiro, Subhadeep Das, Faith Wallace-Gadsden, and Jean-Christophe Quillet will be there representing Stämm and running the first public demos of the HTB: our High-Throughput Bioprocessor live.

Recently, I was teaching the Law of Large Numbers and diversification, so I decided to share this illustration here. As you average more and more independent, identically noisy copies of an image, the noise cancels out and the original emerges. Code in the comments.

my (first!) article, “From the virtual community to ‘Trust and Safety’: eBay (1995–2007) and the rise of platform governance” is out on Big Data & Society! it is a history of content moderation at eBay, where they coined the term Trust and Safety 🌐 link below

can confirm these are the vibes if you’re questioning whether staying in academia, quant, big tech, or a big lab is how you want to spend the singularity, hit me up

For decades in the biopharmaceutical industry, bigger was better: massive tanks, sprawling facilities, global blockbusters. But rising biosimilar competition and demand for specialized therapies are forcing a shift. The old batch paradigm is giving way to a new way.

Never been a better time to pivot into biology. The problems are very far from solved. Engineering skills will be extremely important in continuing to push the frontier forward. It's hard, but wildly worthwhile. Leave B2B SaaS to agents :)
as a software engineer, i feel a real loss of identity right now. for a long time i defined myself in part by the act of writing code. the pride in a hard-earned solution was part of who i was. now i watch AI accomplish in seconds what took me hours. i find myself caught between relief and mourning, awe and anxiety. the craft that shaped me is suddenly eclipsed by a machine. who am i now?

Representation learning is the idea that instead of hand-designing features, algorithms should learn the best way to represent data directly from examples. In probability theory, this corresponds to finding latent variables or transformations that make complex joint distributions simpler and closer to independent, which improves inference and prediction. In statistics, representation learning appears in factor models, principal component analysis, and mixture models, where high-dimensional observations are summarized by a few informative hidden components. In machine learning, deep neural networks, embeddings, and autoencoders learn hierarchical representations that capture edges, shapes, words, meanings, and abstract concepts, enabling powerful performance in vision, language, and recommendation systems. In real life, representation learning allows computers to understand faces, voices, medical scans, and user behavior by converting raw signals into meaningful patterns. By discovering the right internal coordinates of data, representation learning makes learning, generalization, and decision-making possible at scale. Image: share.google/9IwlvggLkIyCFo9…

Learned something very interesting today! Random projections of a non-linearly separable data onto high dimensional spaces is enough to make it linearly separable. Consider a dataset like XOR that you can't linearly separate. Now, if you project each 2D point onto a D (=50) dimensional space using *randomly* initialised basis vectors, each direction creates a tiny difference between the classes (e.g. gives 51-52% accuracy) because expectation of two classes differs slightly when randomly projected. So each randomly projected feature becomes a tiny discriminator and when you aggregate it over 20-50 such discriminators, a linear classifier is able to separate them perfectly by simply learning how much to weigh each feature. One intriguing possibility of this is that we're able to train deep networks because random projections make most of the data already separable, making the job of gradient descent easy.

Take two large random matrices and linearly interpolate between them at several hundred steps. Compute the eigenvalues for each interpolated matrix, then plot them in the complex plane. The result is shown here. Made with #python #numpy #matplotlib

Biology as an industry is massively underappreciated for its scale, value and success because when people say biotech they mean pharma and not using technology and genetics for agriculture The pig industry alone is equal to the global smartphone market
Biotech is the industry with the lowest success rate unfortunately, but at the same time trying to solve the problems that are worth solving the most.
