In April, I will be starting my research group at the Leibniz Institute for Food Systems Biology at TUM.
๐ป๐ฃ Our work will focus on developing computational methods to integrate and analyze omics data in a food biology context
Weโre excited to be back at the Heidelberg spatial omics seminar series today ๐
I think that is the core of the peer-review crisis. If we were to only do peer review of the scientific work that is both important enough and non-trivial, we would all save a lot of time. It will obviously be a challenge to decide what needs to be reviewed, I acknowledge that.

We have been working with Michal Klein on pushing a module to train *flow matching* models using JAX. This is shipped as part of our new release of the OTT-JAX toolbox (github.com/ott-jax/ott)
The tutorial to do so is here: ott-jax.readthedocs.io/tutorials/ne...
Look at the numbers! They are great! Good numbers, bold numbers, we have the best numbers!

Extremely honoured to receive the Bayer foundation early excellence in science award. Thanks to all my team, colleagues, collaborators and mentors for making this possible!
My take: Engineering *is* important. Ideas are cheap. Novelty is overrated. "Hyperparameter tuning" is a cynically dismissive term for something that is in fact the real, difficult problem.

I always find it funny that we obsess over sample size, yet peer review relies on the arbitrary opinions of just 2/3 people. That would be fine if editors were truly engaged, but given the workload, they donโt have the time, or donโt care enough. Anyway, Iโm just glad it finally got published! ๐
@embl.org PhD programme just open - many interesting projects, including two with us @saezlab.bsky.social @ebi.embl.org - one on #host-microbiome interactions using #spatial omics, and one on #AI in #proteomics ๐
Very happy to share our latest publication unravelling how the #ERstress sensor ATF6 stirs up trouble (and tumors) in #colorectalcancer. ATF6 drives CRC by reshaping lipid #metabolism and the intestinal #microbiota. A huge thank you to all co-authors! #lifesciences
