My laboratory tackles questions in ecology and cell biology in aquatic organisms using a range of biophysical, physiological, biochemical and molecular tools. Although we tend to focus on planktonic systems, we are also interested in benthic and near-shore processes, and we work across the spectrum of living things, from bacteria to fishes. We move freely between the laboratory and the field. Our efforts have been informed by new genome sequence information becoming available, and we have been involved in several genome annotations of algal species.
We are especially interested in:
- developing indices of biological rates and processes in aquatic
ecosystems using a variety of biochemical and molecular methods, especially those involving
- characterizing responses to stress and environmental change, using biophysical
and biochemical approaches.
