April 2013: The winning Crucible team at the final event brought together researchers from Heriot-
Watt University (Dr Mark Hartl, School of Life Sciences and Dr Paul Dalgarno, School of Engineering
& Physical Sciences) and University of Edinburgh (Dr Maria-Chiara Ferrari, School of Engineering
and Dr Stephen Moggach, School of Chemistry) in a project called "Tragic Plastic" which aims to
reduce the amount of plastic pollution in the marine environment through development of an
automated microplastic particle detection system. Read more about the Heriot-Watt Crucible V.

July 2012: Dr Mark Hartl, as President of the Physiology Section of the American Fisheries Society,
chaired the plenary session at the 10th International Congress on the Biology of Fish. There were
four excellent talks from Dr Jonathan Wilson, Dr Peggy Biga, Dr Suzie Curry and Prof Lluis Tort (top).
Also Prof Carl Schreck gave an inspiring talk following the Award of Excellence in Fish Physiology
(second from top). Dr Brian Small, incoming Physiology Section President, presented Dr Hartl with a
certificate of appreciation for his Tenure 2010-2012 (centre). Student delegates receiving travel
buraries sponsored by an NSF grant and the AFS Physiology Section (second from bottom) Dr Lynn
Wever, Prof Chris Kennedy and Dr Hartl organized and chaired the toxicology symposium.
