Dr. Alice C. Ortmann
Working with the team at the Centre for Offshore Oil, Gas and Energy Reserch (COOGER), I carry out research to understand the fate, behaviour and effects of oil following a spill in the aquatic environment. My research specifically focuses on the interactions between oil and microorganisms, including those that can alter the fate and behaviour of oil. This includes organisms that can degrade the oil, transform the oil or alter the density of oil. To understand these interactions we use a range of analytical techniques, including genomics, applied to field and lab-based experiments.
Current research and/or projects
