Research interests

I am a marine microbiologist with a particular interest in microbial community dynamics in ocean ecosystems. I strive for a holistic approach to answering scientific questions through collaborations with microbiologists, ecologists, engineers and physical oceanographers. I have spent the last 8 years focusing on the Southern Benguela Upwelling region, with a specific focus on how the resident microbial community is affecting critical nutrient cycling here.
