Academic Diving Manager

School of Biological and Marine Sciences (Faculty of Science and Engineering)

As the University Diving Officer and Academic Diving Manager I am responsible for managing all diving carried out by staff and students at the University of Plymouth, excluding diving carried out by the Student Union SCUBA Society. My remit includes diving carried out on the HSE SCUBA courses run by the University, the Scientific Diving module (OS207), diving on student placements and student dissertations and diving by staff to collect samples, or gather data for their research. My responsibilities extend to diving both in the UK and overseas.   

In addition I am the academic module leader for a Scientific Diving module (OS207), teach on Fish and Fisheries module (MBIO363) and act as adviser to BSc, Masters and PhD Students.  


BSc Marine Biology/Zoology - Bangor University 1994
PhD - University of Aberdeen 1998

After completing my PhD, I worked for the British Antarctic Survey from 1998-2008 as a Marine Eco-physiologist. During this time I worked in the Antarctic and Arctic and have dived extensively in the Antarctic and at South Georgia. After leaving the British Antarctic Survey I worked for the Government of South Georgia for 6 years as a Government Officer managing fisheries and tourism and as the Operations Manager overseeing fisheries management, fisheries patrolling and the management of large scale environmental projects. While based in the Falkland Islands I dived with the Shallow Marine Survey group in many areas of the archipelago.      

I have dived professionally for 22 years and recreationally for 29 years.
