Phycology, cross-kingdom interactions, biogeochemistry, microscopy and, recreationally, the microbiology of fermented foods. 

I am a graduate student in Dr. Sonya Dyhrman's microbial oceanography laboratory; I'm most interested in the molecular underpinnings of how marine microorganisms (and their viruses) interact with each other and their environment, and ultimately biogeochemical implications of these interactions.

Fields of interest: 

Geomorphology, Glacial Geology, Hydrology

I'm best labeled as a geomorphologist. Landscapes are, in part, a product of erosion, and my work aims to decipher clues about the patterns and rates of erosion recorded in landforms.

Erosion is especially dynamic in rugged landscapes, so as a geomorphologist I'm particularly drawn to high-mountain regions. I'm currently focused on a few tropical mountain belts, specifically those that show signs of glacial erosion. My work uses a combination of terrrestrial cosmogenic nuclide methods and remote sensing to describe the timing and nature of glacial erosion in these landscapes.

Fields of interest: 

Isotope geochemistry, paleoclimatology, paleoceanography, marine biogeochemistry

My research interests involve the application of major elements, trace elements and isotopes to investigate the interface between climate, biogeochemistry, and the environment. I am particularly interested in the tropics, and my recent projects have included stable isotope (dD) geochemistry in Ethiopia, redox (Fe, Cr, U) variability in Indonesia, and productivity and dust (231Pa/230Th, 232Th, d15N) fluctuations in the Central Equatorial Pacific. In my upcoming work, I will investigate the relationship between volcanism and global climate change at orbital timescales by tracking changes in hydrothermal vent activity as recorded in marine sediment cores from the Juan de Fuca Ridge.

My primary research interests are:

  • The role of ocean circulation (particularly the Southern Ocean) in the climate system
  • Dynamics of the Antarctic Circumpolar Current and its overturning circulation
  • Mixing and transport by ocean eddies

I am broadly interested in how marine microbes like phytoplankton interact with their geochemical environment, where I use molecular level tools to study the intersection of microbial physiology and biogeochemistry.

Microbial oceanography group members are using a suite of genome-enabled approaches to examine the distribution and activities of marine phytoplankton, and how they influence cycling of carbon, nitrogen and phosphorus. Our work often uses model cultures to understand and bound field observations made on research cruises that span the from polar to tropical systems. This research emphasis provides advanced training for undergraduates, graduate students, and postdoctoral scholars and it is also used as a framework for the development and implementation of inquiry-based educational activities for children.
