Really important work (and delighted to help) using pulmonary hypertension as a disease exemplar. Applicable across all rare disease I expect.

One of my students @StEdmundsCam has a really remarkable story of overcoming adversity to study @Cambridge_Uni. Sadly his scholarship can't fund the rest of his degree so he is trying crowdfunding. Any help would be really appreciated, thank you very much! gofundme.com/f/from-poverty-…

New pre-print online: "Context-stratified Mendelian randomization: exploiting regional exposure variation to explore causal effect heterogeneity and non-linearity", arxiv.org/abs/2507.11088. We propose an alternative approach to assess non-linearity in Mendelian randomization.

Posting a tad late, but @jamesyrmsk and @dpsg108 and I have a new research letter in @intjepidemiol where we use negative controls to illustrate why drug use phenotypes should not be used as exposures in MR studies academic.oup.com/ije/article…

🚨 New preprint awaiting feedback! 🚨 led by the lovely and talented @martaalcalde18 looking at the relationship between PDE5 inhibition and Alzheimer's disease using #mendelianrandomization (spolier: we found nada) medrxiv.org/content/10.1101/…

And the accepted m/s is now out in the AJE! academic.oup.com/aje/advance… Thank you to @htcronje @dpsg108 @stevesphd @LoukasZagkos @LarssonSC Summary can be found x.com/BarWoolf/status/166459…

Had a lot of fun presenting our work (accepted this week at the AJE) on exposure miss-identification in MR, and how it results in directionally incorrect conclusions for studies of caffeine consumption at #mrconf24.

Do biological mechanisms leading to penis stiffening make men happy? Do they make them more fertile? Find out in our new drug target Mendelian randomization article, led by @BarWoolf and now out at @bmj_latest: bmj.com/content/383/bmj-2023…
