[Scientists] OSCAward for ALL-IN-META-BCG-CORONA
Here I share the story of the project that motivated me to nominate it, see the nomination text below. Lessons learned in terms of the unique features of the ALL-IN approach appeared in an updated (V2) version of the ALL-IN paper: ter Schure J and Grünwald P. ALL-IN meta-analysis: breathing li...

[Scientists] What I tried to achieve with a ResearchEquals collection
How I did the best I could and spent a large amount of time, still gave up before fully completing it, am happy I tried it, happy I gave up, and happy with the result. ResearchEquals is a research publishing platform that is used by open science enthusiasts like myself. This blog post is...

[Peers] E-values have a wikipedia page
The research field I work in, that of anytime-valid statistics and e-values, now has a Wikipedia page! [https://en.wikipedia.org/wiki/E-values](https://en.wikipedia.org/wiki/E-values)

[Scientists] Avoidable research waste caused by data transfer agreements
Early summer of 2020, eight trials agreed to collaborate in a prospective meta-analysis and keep a live account of the pooled results. Each was interested in the question whether the BCG vaccine, originally develop...

[Peers] Dataviz matters! Update to my Ph.D. thesis
The final question at my Ph.D. defense was by prof. Richard Gill. He saw an easy improvement to the data visualization in the introduction of my Ph.D. thesis. Not that I was too happy about it myself. The main point of the figures was that sampling distributions and p-values depend a lot on the sample size (the number of heart attacks n, in the example) – you can only visualize them in this way given a sample size or stopping rule. That was still clear from the figure, but it was very distracting and counterintuitive that the distributions in the figure shrank, for which I had to add a long caption below Figure 1 of my Ph.D. thesis. It was October 2021, and I had set the deadline for my Ph.D. thesis to November 1st. I simply did not see the easy fix. Thanks to Richard, my Ph.D. now has better figures. Also thanks to Nicos Starreveld, who wrote a very nice article about my Ph.D. thesis that reuses the improved figure. The updated Ph.D. thesis can be found in the Amsterdam UMC repository. In this blogpost I also post the improvements to Figure 2 and Figure 3 that follow.

[General] Infographic!
Het is echt een hardnekkig fabeltje. Zelfs tijdens een sessie over lawines beweerde een spreker uit een Alpenland: “Jullie lopen meer risico op de autobahn naar de bergen toe, dan in de sneeuw daar!”Hoe gevaarlijk is skitoeren nu echt als je het vergelijkt met autorijden? Op de VVSOR blog publiceerde ik een infographic die dat uitlegt.

[General] Great summary article about my Ph.D. thesis
Nicos Starreveld writes a fantastic series of articles in the member's magazine of the KWG ('Koninklijk Wiskundig Genootschap', Royal Dutch Mathematical Society). He reads recent Ph.D. theses with great care and interviews Ph.D. candidates in mathematics that are preparing for their defense. The series is called 'In Defense'/'In de Verdediging' and appears (mostly) in English. This is an article that discusses the work of my current colleague dr. Birgit Sollie and this is an article in the series on the work of my former colleague dr. Yfke Dulek. I especially like the description of mathematical work as tirelessly exploring how something can be done, resulting in constructing an impossibily proof that also makes you happy.I was very honored for my Ph.D. thesis to be featured in the piece that appeared in December. You can read it here. It provides a great summary of the main themes of my Ph.D. thesis: research waste, accumulation bias, and of course: ALL-IN meta-analysis

[Peers] Best Oral Presentation: Evidence-Based Research
I received an award for a talk!The goals of EBR – or evbres: Evidence-Based Research – have been central to the work in my Ph.D. thesis on ALL-IN meta-analysis. During the EBR conference I argued that these new statistical methods could be the future of EBR, and received a Best Oral Presentation award for it. (Here's the Twitter announcement.)The great thing about online conferences is that you can still watch the presentation on the EBR conference' Youtube channel.Read more about Evidence-Based Research on the EVBRES website.

[General] Defense, title and signature!
On April 7th 2022, I successfully defended my Ph.D. dissertation, received my "Dr." title, and signed the famous "Zweetkamertje" of Leiden University!Many were there with me! I want to thank my supervisors Peter Grünwald and Daniel Lakens and the reading committee that evaluated my dissertation: Jelle Goeman, Joanna in 't Hout, Glenn Shafer, and Alex Sutton. It was a very inspiring discussion following the questions from the opposition committee: Glenn Shafer, Joanna in 't Hout, Henri van Werkhoven, Jelle Goeman, Hein Putter, and Richard Gill.Everything went super smooth, thanks to my wonderful paranimfs Laura Schut and Marnick van de Zande. I really couldn't have done it without them!And I want to thank my family, friends, colleagues, and CWI for their support. This was a truly great day! A news article about my defense can be found on the Leiden University website (in Dutch) and on the CWI website (in English). The complete dissertation can be found in the Leiden University Repository and the CWI Repository.I did not want to share photos unasked, but my paranimfs insisted that this diploma photo-op was made for posting:

[Peers] My propositions!
Ten propositions, following Leiden tradition, with at least four about my dissertation, four about my field and at most four personal statements. They do not appear in the Ph.D. dissertation itself: it is custom to add them on a separate sheet in the printed book. So they are easily lost. Here, I try to make them easy to find!
