Dr. Margrethe (Gretta) Serres

Research Associate III

My main research interests are in microbial physiology, including the metabolic diversity and plasticity of prokaryotes and how these traits are shaped by environmental factors, community interactions, and evolutionary history. I have worked with pathway genome databases to curate and predict functions and metabolic pathways, analyses that span individual model organisms, groups of related bacteria, and complex natural microbial communities. Beyond my technical duties in the Huber Lab, I also serve as a faculty member at Cape Cod Community College and the Coordinator for the Community College Comprehensive Research Experience at WHOI (CC-CREW) program. In this role, I oversee daily activities for the 3-4 community college students in the Huber laboratory, providing research and mentorship support to the students.


Dr. Bayleigh Benner

NSF Postdoctoral Fellow

Bayleigh is a molecular virologist and microbiologist who is interested in uncovering the viral diversity present in marine and freshwater ecosystems. Her current research focuses on utilizing genomics-based approaches to identify viral populations and virus-host interactions present within deep sea ecosystems. She aims to characterize the poorly understood roles that viruses play in global biogeochemical cycling, microbial adaptation, modulation of host metabolism, and the evolution of life on Earth. Bayleigh is currently a National Science Foundation Postdoctoral "Rules of Life" Fellow.


Sabrina Elkassas

MIT-WHOI JP Graduate Student in Chemical Oceanography

Sabrina Elkassas joined the lab after majoring in Earth and Environmental Science with a concentration in Geology at the University of Pennsylvania. Her undergraduate thesis used already isolated strains of chemosynthetic bacteria from deep-sea hydrothermal vents to investigate how these microbes can be used for bioremediation of the physical and chemical health hazards of asbestos. At WHOI, she is working on a NASA-funded project using deep-sea Earth microbes to understand the potential for life on Ocean Worlds of our solar system.


Dr. Elaine Luo

WHOI Postdoctoral Scholar

Elaine joined the lab after doing her PhD in oceanography at the University of Hawaii.


Dr. Sarah Hu

Postdoctoral Investigator

Single-celled microbial eukaryotes encompass a wide range of genetic, morphological, and functional diversity, positioning them at the epicenter of complex aquatic food webs. By understanding microbial eukaryotic nutritional roles (i.e., phototrophy, heterotrophy, and mixotrophy) and the impact these activities have on the surrounding microbial community and environment (i.e., rates of bacterial mortality, carbon transfer, regeneration of basic nutrients, etc.), we will have a more complete knowledge of their contributions to global biogeochemical cycles and how energy and carbon flows through to other trophic levels. I am a microbial ecologist and oceanographer working to characterize the in situ community and metabolic diversity of microbial eukaryotes. Currently, I am working on ways to combine molecular techniques and grazing experiments to understandmicrobial community structure and identify transcriptional patterns associated with key metabolic strategies.

Emilie Skoog

Guest Student, MIT Earth and Planetary Sciences

Emilie is a PhD student in the EAPS department at MIT. She is interested in understanding the origin and evolution of life on early Earth by looking at microorganisms preserved in the rock record and analyzing modern analogs found in microbial mats and hydrothermal vents today. Her current research at MIT focuses on performing metagenomic and physiological analyses of these extant cyanobacteria from ancient stromatolites across the globe. At WHOI with Julie, she is working on isolating viruses from hydrothermal vent organisms and understanding the host-virus relationship.
