Ocean Carbon Cycle and Acidification
Research Interests: Sediment biogeochemistry, nitrogen cycling, and ecosystem modelling.
Paleooceanography and sediment transport (Research Focus: Export Marine Export Production and Atmospheric Dust; Sea Surface Temperature and Storminess in the Western North Atlantic-last 2000 yrs.; Contamination of Coastal Sediments)
Paleoceanography and sedimentary biogeochemistry
Remote sensing and modeling of atmospheric composition
Modelling and prediction of marine extreme events, and physical oceanography of coastal waters.
Marine carbon cycle, CO2 air-sea fluxes
Ocean-atmosphere exchange, carbon cycle, observing technologies.
My lab studies marine microbes and their influence on global biogeochemistry. I am particularly interested in 1) the roles of micronutrients in shaping marine microbial communities and 2) in using quantitative, mass spectrometry based techniques to study microbial activity.
Human-induced changes in marine populations, communities and ecosystems
Understanding how private-and state-based governance can combine for cooperation of common pool marine resources.
Coastal and ocean management, fisheries governance, regional ocean governance, science/policy interface.
Evolutionary ecology & biology of fishes.
Marine microbial genomics and marine biogeochemistry.
My lab study's the factors that regulate populations of benthic marine invertebrates of ecological and economic importance, using a combination of approaches, such as field sampling, laboratory experiments and mathematical modelling.
Research Topics: Acoustical oceanography, passive acoustic remote sensing, instrument design and signal processing
Investigations of mid-ocean ridges, subduction zones, rifted margins, and sea level change using controlled source seismology
Igneous petrology, mineralogy
Intelligent autonomy for marine autonomous vehicles, multi-agent systems, underwater vehicle and tow body dynamics, underwater acoustics
