Profile

At Te Kura Kairūri I manage Hydrographic Surveying – teaching students and working with researchers from Surveying, Marine Science and Geology, as well as running demonstrations with visiting school students. I am a past student of the School of Surveying, and joined the staff in 2013.

I have been part of several research cruises on the university research vessel Polaris II and am on the management team for our new multibeam echo sounder. I teach practical hydrography skills around Dunedin Harbour and along the Otago Coast on the university research vessels Polaris II, Beryl Brewin and Tūhura.

Prior to coming to Otago I completed my MSc (Hydrography) on the FIG/IHO/ICA recognised Category A course in Plymouth, UK. My background also includes several years working worldwide on a variety of hydrographic projects including charting, habitat mapping, oil and gas, renewables and offshore construction.

I thoroughly enjoy being at sea and like to learn, share and apply all aspects of nautical knowledge to my teaching.
