I love when I come across something super niche on HN where I actually know someone working in it. A friend of mine from college (university), Ibrahim Cissé, now runs a lab[0] in this space, and while the description of his work is way over my head, I imagine some of you might find it interesting:

> Laboratory Ibrahim Cissé > Single Molecule and Super-Resolution imaging in live cells > We leverage expertise in Single-Molecule and Super-Resolution imaging in live cells to study collective behaviors (e.g., protein clustering) emerging from weak or transient biomolecular interactions in mammalian cells. We unveil, often for the first time, that these clusters exist in living cells, and we expand both on the imaging approaches and the cellular and molecular biology techniques to discover the biophysical mechanisms of action and their function in vivo.

Or for a quick layman's explanation, here's a YouTube video of him describing his work when he won a MacArthur Fellowship [1].

I'm grateful for HN for reminding me of him and giving me an excuse to look up his work a little more in-depth.
