My first bluesky post of 2026. I was away in the UK, for meetings with colleagues but also got to sneak in a few visits with more friends, old and new alike. In what has been a turbulent and disquieting year across the world already, personal connections and support are more important than ever.

Always happy to be involved in work that better explains how parasite cells function. Especially in a group like apicomplexans with such a global health impact (Malaria, Theileria, Cryptosporidium). The more we know, the better people are able to find ways to combat them.

OK sure, it started out as a typo, but I d like the idea measuring of a gene or protein's "Conswervation". Just feels more groovy and less judgemental than 'divergence".

Moving fast and stressing hard about getting things done before vacation (and being grumpy about it). Then I opened my laptop to the news of the passing of a mentor and colleague. Her memory will be a blessing and guide. Good reminder about priorities today, though. Connections over check-lists.
