I am developing machine learning approaches to harness the information contained in the electronic health records, national registries and biobanks for improved disease diagnosis and healthcare resource allocation. Based at FIMM, University of Helsinki.
My colleague Essi Viippola will be presenting our recent results at #ASHG2025 at the poster session on 15.10 at 2:30pm-4:30pm. The title is:

Genetic and phenotypic underpinnings of within-genetic sex variability in human plasma proteome across 51,292 individuals and four studies [Board no. 1010W]
We’re getting ready for an exciting week at #ASHG2025 in Boston! Come meet the FinnGen team at booth 147 - we’ll be sharing updates and showcasing new public resources and tools. Plus, don’t miss the various presentations featuring FinnGen results across the program!

Are you interested in pushing the limits of what population health "foundation model" could be used for? Would you like to study privacy and fairness of generative models that are trained on sensitive health data? Or combine this with your own ideas?

Two weeks left to apply to this PhD position 👇
I am hiring! 🎓

We offer a fully funded PhD student position to work on exciting machine learning projects utilizing rich, multimodal real-life health data, based at @fimm-uh.bsky.social in Helsinki, Finland, the happiest country in the world 🇫🇮

You know those really annoying but really niche tasks? Like ordering a long author list and correctly numbering each affiliation and linking them to correct author to produce the final "authors and affiliations" block in a paper.

I never intent to do this manually again:

A new blog post 💡

Generative AI trained on 100M+ real health trajectories?! 🤖

I am experimenting with this "short review" format where I aim at highlighting just a couple of quick point from an interesting paper. Let me know how it works!
Short review: "Generative Medical Event Models Improve with Scale."
This is my first try on this “short review” format.

Are electronic health records (EHR) more predictive of disease onset than polygenic scores? Can we transfer EHR-based prediction models between countries? Our study on these questions using 3 biobank-based studies with N>845K, is out in @natgenet.nature.com today:

Cross-biobank generalizability and accuracy of electronic health record-based predictors compared to polygenic scores - Nature Genetics
Comparison of electronic health record-based phenotype risk scores (PheRS) and polygenic scores (PGS) across 13 common diseases and three biobank-based studies indicates that PheRS and PGS may provide...

I started an experiment: a blog in substack! My idea is to mainly post short reviews about interesting papers at the interface of AI and health sciences, but also stuff related to other aspects of science life.

The first post actually is of the latter category 👇

Travelling to a scientific conference in Italy from Finland - without flying
As a scientist, flying to conferences and international meetings has for some time bothered me.

Science’s ‘Gollum effect’: PhDs bear brunt of territorial behaviour
Nature - Survey respondents at all career stages report colleagues engaging in territorial and possessive behaviours — but early-career researchers are most often affected.

Did you know that some genetic males have plasma proteomes similar to those of genetic females and vice versa? What are the consequences of this?

Come discuss with me at our poster number P18.021.D on Monday 26.5. at 4pm-5pm at #ESHG2025

It is time to try how travelling to conferences without flying works when you live in the "far north". The first leg is from Helsinki to Copenhagen, where I will be attending the Genomic Mechanisms of Disease conference. From there I will continue to Milan for #ESHG2025 . A thread follows 🧵 1/n
