marine microbes & ocean ecosystems

  • A group of people standing together indoors, smiling for a photo in front of a wall. They are dressed casually in jeans and various styles of footwear.
  • A modern building surrounded by trees and grass, with a clear sky and scattered clouds above. The structure is part of the Cancer/Genetics Research Complex, located on a university campus.
  • A brick sign displaying the University of Florida logo, surrounded by greenery and flowers under a clear sky.
  • A collection of test tubes filled with various colored liquids, arranged in an indoor setting.
  • A boat floating on water with a vibrant sunset in the background, casting colorful reflections on the surface. The sky is filled with clouds illuminated by the warm hues of the setting sun.
  • A woman wearing blue gloves is holding a pipette aboard a ship.
  • A woman is standing, examining a piece of equipment. The background features a wall and ceiling.
  • A man wearing a yellow helmet and a life jacket is standing on a dock, holding a large device, with water and a ship in the background under an open sky.
  • A group of people standing on the deck of a boat with water surrounding them.
  • A group of transparent bottles arranged on a table, with a wall in the background. The bottles are partially filled with liquid.

Our research focuses on how microbes interact with each other and their environment to influence carbon, sulfur, and energy cycles.


​To understand the dynamics of microbial interactions and function in the ocean, we use a combination of molecular and chemical approaches, both in laboratory studies using model microbial species and field-based observations of natural populations. While our research primarily focuses on ocean microbes, we also work collaboratively to examine microbial metabolic interactions in other aquatic and terrestrial ecosystems. Some of the tools & techniques we employ to study microbes include microscopy, liquid chromatrography-mass spectrometry (LC-MS)-based metabolomics, community sequencing, molecular genetics, and isotopic rate measurements. In addition to our research in the lab and field, we have an education mission centered on incorporating experiential learning into STEM courses and making ocean science inclusive and accessible.

​Current projects include:

  • characterizing organic sulfur genetic pathways and their metabolic regulation in phytoplankton and bacteria
  • analyzing the impact of environmental variables and intercellular interactions with bacteria on marine phytoplankton, including both model-system and Harmful Algal Bloom (HAB)-forming species
  • examining the structure and function of microbial-associated metabolic networks in natural communities over space and time to determine their ecosystem impacts and bridge what is found in lab and in nature
  • developing authentic research-based course experiences for undergraduates and investigating how these opportunities influence their relationship with science and the scientific community
