The dissolved organic matter pool in the ocean is an important component of the global carbon and nitrogen cycles. However, the compounds present in this pool and their cycling is largely unknown. The primary focus of my research is the compound-specific study of marine organic matter cycling; investigating what compounds are present in seawater, their sources and sinks, and the biogeochemical processes involved in their cycling. In pursuing these research interests I have worked with a variety of environments and disciplines; sediment/water interactions, riverine processes, hydrothermal systems, temperate and polar open-ocean systems, and microbial ecology.

 

Active research projects:

  1. Organic geochemistry of a hydrothermal system
  2. Effects of particle aggregation on organic chemical speciation and cycling
  3. Cycling of styrene in coastal environments
  4. The effect of anoxia on organic-matter fluxes from sediments to overlying water.
  5. Developing method for low-molecular-weight organic acids
  6. Organic matter cycling in the Arctic

At present, I supervise four graduate students: Alejandro Arias, Tzong-Yueh Chen, Eric Miller, and Elisabeth Svensson. Alejandro works on the effect of anoxia on organic-matter fluxes from sediments to overlying water, Yzong-Yueh works on effects of particle aggregation on organic chemical speciation and cycling, Eric works on cycling of styrene in coastal environments, and Elisabeth works on two projects: organic geochemistry of a hydrothermal system and developing a method for low-molecular-weight organic acids.Below you will find the graduate classes I teach at Avery Point. I also teach the undergraduate class MARN170 Introduction to Oceanography at the Storrs campus.

Since I am a new faculty member, my graduate classes do not yet have regular class codes, but are called 410s. The different professors that teach 410s have different section numbers. If you want to take one of my graduate classes you would sign up for a 410, my section number. Unfortunately, the section numbers vary between semesters. Contact me to get my section number.

If you are an undergraduate and want to take one of my graduate classes, read the syllabus, contact me and we can discuss if you have the appropriate background.
