Hi everyone! I used to post primarily on X, but with the recent turmoil, I'll be cross-posting on both sites for now.
I'm a computational clinician researching B-cell lymphomas, microproteins, and ctDNA. You can learn more about my current projects on my GitHub:

Research into regulatory "backbenches" proteins pays off: fewer adverse effects, higher specificity and the ability to target “undruggable” proteins. Examples: Nav1.7 channel regulator (Regulonix) and glutamate or acetylcholine receptor associated proteins (Rapport Therapeutics).

Increasing demand for novels in the 19th century in England correlated with improving literacy (60% of men, 40% of women in the 1800s vs. 97% by the 1900s). Reading was no longer an upper-class domain. It's ironic how an objectively positive change was criticized from a normative side.
Back in the early 1800s, when novels started taking off, they faced significant criticism. Some reviews from that era resemble today’s arguments against the widespread use of AI.

I really enjoyed this episode! I think biology as a cumulative science feels inefficient because hypothesis generation and exploration often depend on individual intellectual preparedness when interpreting data. Choosing one strategy over another reflects preference rather than methodological rigor.
🔥Today's new episode of the Night Science Podcast is super cool: A hypothesis is a liability! We talk about the interplay between hypothesis-driven and exploratory research, and discuss the insights of previous guests of the podcast. I'm really curious to know what you'll think!

Unpopular opinion: Biomedical science is over-regulated, slowing progress by focusing too much on hypothetical risks. Many issues stem from sloppy research or individual irresponsibility, which regulations can’t fully prevent.

Our latest work is out in Nature today! Using smFRET, we directly visualized recruitment of the eIF4F complex to the 5' cap of eukaryotic mRNAs and formation of an activated mRNA. Our findings reveal new and surprising roles for each eIF4F component. 1/3 www.nature.com/articles/s41...

Fascinating paper on unannotated splicing junctions between exons and transposable elements (JETs). Pervasive, but very contextual expression increasing proteome diversity.

SM has become so dull lately. Over there, it’s mainly Elon rambling and trolls (is it me only?), while here, the feed still lacks momentum. I miss the old Twitter, where I could browse papers and enjoy some spicy cultural or political drama in the same time.

and also it dovetails largely with the microproteins work on essential non-canonical ORFs that several groups have been studying including my own.

The unfortunate reality is that this wouldn't be possible today. The UK chose not to participate as an associated third country in the new Erasmus+ program.
It also brought back memories of my own elective at Oxford in 2015. I received an Erasmus+ scholarship for a mini research project on stress responses in cancer, which kicked off my research journey and led me to leave Warsaw to start my PhD at Cambridge two years later.
