Sarah Guerin

Dr Sarah Guerin is the Principal Investigator for the newly-established Actuate Lab in the Department of Physics and Bernal Institute in the University of Limerick, Ireland. She currently works on both in-silico and ex-silico engineering of biomolecular crystals, primarily for application areas in eco-friendly sensing and pharmaceuticals. Sarah has been successful in securing €2M of funding from Science Foundation Ireland and the European Research Council for the development of organic piezoelectric device components.

She currently works with a large number of international research groups as a world-leader in computationally predicting the electromechanical properties of novel molecular crystals.

She has been awarded the British Association of Crystal Growth Young Scientist of the Year Award and the IEEE Dilip Das Gupta Memorial Award.
