Neuroscientist by training, tinkerer by nature. Now scanning transparent mouse brains with light-sheet microscopes. Microscopy, clearing, data crunching, tinkering.
Working as postdoc at @radboudumc with Nael Nadif Kasri and Corette Wierenga, looking at neuron-distribution differences in mouse models of ASD.
Married, father of two. Toots in English, German, Dutch. Boosts a lot.

Das klingt super simple und einfach cool für Prüfungen: psi-exam läuft auf Debian Linux auf autarken Laptops, die weder Strom- noch Internetanschluss brauchen .
Damit kann man über 300 Teilnehmende gleichzeitig prüfen, auch in eher spartanisch ausgestatteten Prüfungsräumen.

Now that important academic data in the United States of America may disappear, a large group of European academics have started duplicating and sharing that data. Henrik Schönemann, the initiator, is even looking beyond this. “Universities must have digital sovereignty.”
I revived an old HDD with a #RaspberryPi Zero W 2 for #DataRescue:ing:
It runs ...
(a) a Bittorrent client that seeds at-risk data sets from the #SciOp database
(b) the `sciop-scraper` script to get new datasets into the swarm
Setup instructions for the Pi Zero: https://codeberg.org/nicebread/HiveSeed/src/branch/main/L1-RDRN_RPi.md
Setup instructions for `sciop-scrape` (on macOS & RPi): https://codeberg.org/nicebread/HiveSeed/src/branch/main/L1-sciop-scrape.md
Let me know if the instructions work for you; happy to collaborate on the manual.
Hackathon: Data Under Threat / Data Rescueing (Aug 7) in #München
The LMU Open Science Center (@lmu_osc) runs a hackathon to support the #SciOp #SafeguardingResearch initiative: Rescuing research data that is deleted by the Trump administration.
Bonus: @lavaeolus will give an ignition talk!
📅 Thursday, 2025-08-07, 16 – 19 (only in-person)
👉 Details and signup: https://github.com/lmu-osc/safeguar.de-hackathon
Become a data rescuer by turning your own laptop into a Research Data Rescue Node, scraping at-risk data sets, and breathing new life into your old HDD as part of a global, decentralised network.

Excellent news! We got a small amount of funding to hire two people half time to help put together a Horizon Europe proposal for Safeguarding Research and Culture [1].
The idea is to develop the SciOp catalogue software to make distributed archives part of the Fediverse, riding on BitTorrent, and get more institutions, libraries and archives involved. With a focus, in this case, on Europe.
If you are interested in preventing digital cultural heritage materials from falling through the memory hole, preventing marginalised and racialised groups from being erased from view, decentralised, federated and peer to peer technologies and have experience with putting together EU Horizon grant proposals, have the right to work in the EU or UK and would like a part time job starting yesterday for a couple of months, please get in touch!
New preprint! Let me tell you a story about trees, caterpillars, brooms, entropy, and getting scooped by 50 years.
Rooted trees of all shapes and sizes crop up all over biology, computing and elsewhere. How can we best compare the shapes of these myriad trees? 1/14
Although the analysis of rooted tree shape has wide-ranging applications, notions of tree balance have developed independently in different domains. In computer science, a balanced tree is one that enables efficient updating and retrieval of data, whereas in biology tree balance quantifies bias in evolutionary processes. The lack of a precise connection between these concepts has stymied the development of universal indices and general results. We recently introduced a new tree balance index, $J^1$, that, unlike prior indices popular among biologists, permits meaningful comparison of trees with arbitrary degree distributions and node sizes. Here we explain how our new index generalizes a concept that underlies the definition of the weight-balanced tree, an important type of self-balancing binary search tree. Our index thus unifies the tree balance concepts of biology and computer science. We provide new analytical results to support applications of this universal index. First, we quantify the accuracy of approximations to the expected values of $J^1$ under two important null models: the Yule process and the uniform model. Second, we investigate minimal values of our index. These results help establish $J^1$ as a universal, cross-disciplinary index of tree balance that generalizes and supersedes prior approaches.
Gezichtsherkenning in supermarkten, voetbalstadions, tijdens demonstraties... Het wordt op steeds meer plekken om ons heen ingezet. Elke voorbijganger kan worden geïdentificeerd, geanalyseerd en gevolgd. Dat heeft een beperkende werking op hoe vrij je je voelt. Wij vinden dat deze ingrijpende vorm van surveillance niet thuis hoort in onze samenleving.
We nemen geen geld aan van overheden of Big Tech. Jouw support maakt dus verschil. Steun ons werk met een donatie: https://www.bitsoffreedom.nl/?doneren! 💥
Most people, when they think "reef", think of corals. That might be because that is the only one they heard about, as we lost many of the oyster #reef systems that used to dot the European coastline.
@malte Hum... nothing from the top of my head for references. I'm not working directly on that, Ruth Thurstan at Exeter (who authored that paper) might be the person to ask.
As for sediment input, it's not just nutrients. Physical sediment from dredging of rivers and ports, coastal cliff erosion and increased storm activity could overwhelm these systems.
