Dr Mark Tarn


I am currently a researcher at the University of Leeds, working on microfluidic platforms for ice nucleation studies. I obtained an MChem degree (2007) and a PhD (2011) in analytical chemistry from the University of Hull (UK). I then worked as a post doc at KIST Europe (Germany) from 2011-2012 on the development of detection systems for capillary electrophoresis. Prior to my position at Leeds, I was a postdoc on a project involving miniaturised quality control testing in positron emission tomography (PET) radiotracer production from 2012-2016 (University of Hull).

I now work within the Ice Nucleation Group in the Institute for Climate and Atmospheric Science (ICAS) at the University of Leeds, and jointly with the Molecular & Nanoscale Physics (MNP) Group in the Faculty of Mathematics and Physical Sciences.
