About Conrad

Since joining the Department of Biological Sciences I have lectured primarily in the area of marine ecology and oceanography. In addition to coordinating the marine ecology courses (see below) I also contribute to undergraduate courses in environmental science (ENVS101) and ecology (BIOL212).

I maintain an active student research laboratory and really enjoy helping them develop as scientists.  I am looking for new students to join the laboratory and welcome inquires.

When not working I enjoy traveling with my family and outdoor activities. I am a keen (but not very good) surfer, enjoy diving, sailing and hiking.

Research Interests

My area of speciality is benthic oceanography/ecology focusing on the processes that influence the structure and function of soft-sediment communities. Specifically, I am interested in how hydrodynamics and benthic organisms interact to affect sediment transport, recruitment, nutrient fluxes and food supply. Together with colleagues and students, research has been conducted in a wide range of environments ranging from the inter-tidal to the deep sea, a reflection of the extensive occurrence of soft-sediment habitats.
