TIR is extremely lucky to have Oliver Hoeller as its “artist in residence”. Oliver is a scientist and freelance illustrator whose work has appeared on the cover of a number of journals, and who also carries out web design, portraiture, and reportage.

Oliver originally hails from Austria, and did undergraduate research at the Institute for Molecular Pathology (IMP) at the Vienna Biocenter. He moved to Cambridge (UK) for his PhD at the MRC Laboratory of Molecular Biology, working with Rob Kay on chemotaxis in the slime mould Dictyostelium. He then moved to the Bay Area for his postdoc, before returning to Vienna in 2020.

Oliver’s watercolours are available for purchase – either contact him via his website or look at his portfolio on EtsyHis Instagram feed can be found here.

Mark Palfreyman joined TIR as a regular contributor in 2020. He writes: Not all who wander are lost, but most are. I’m one of those. I started my life in France playing with worms, after college in Colorado decided to try it again. I moved to Utah and did a PhD. Then I found some fruit flies in Vienna and played with them. Now I’m taking a step sideways as a duck might step sideways à l’orange; or, maybe more likely, as a coq steps sideways au vin. What I’m currently doing, I know not. 

More of Mark’s artwork and some of his photography can be viewed here.

When nobody’s available to do the artwork for a posting, Brooke puts silly captions on paintings that he likes instead.
