Andrew Montgomery​, PhD                    Researchgate profile             GoogleScholar profile


Andy graduated with his B.Sc. in biotechnology from James Madison University (Harrisonburg, VA) in 2013. His interest in microbiology started in the Viral Discovery program there, where he contributed to the discovery and characterization of several novel bacteriophages. He subsequently earned his Ph.D. in Marine Sciences from the University of Georgia (2021) working with Mandy Joye. During his time in graduate school, Andy explored microbial cycling of methane and other labile organic carbon compounds in extreme marine environments and worked with several strains of Thaumarchaeota (ammonia-oxidizing archaea) to constrain the metabolic capabilities of these unique microbes. Andy was awarded an NSF postdoctoral fellowship to work with Roland and Frank Stewart (also at MSU); he started at MSU in summer 2021. At MSU he is investigating the ecophysiology of deep-sea microbes across geochemical gradients in the deep biosphere of the Guaymas Basin hydrothermal system.

Sylvia Nupp​​   3rd year grad student     


Sylvia earned her B.S. in biology and chemistry from the University of Arkansas in 2021. She started her Ph.D. in biochemistry at MSU in Fall 2021 and is currently studying how microbial community activity varies across geochemical regimes in Guaymas Basin and Pescadero Basin, and the rates and patterns of anaerobic oxidation of methane by microbes in these systems.                                              



William Christian   5th year grad student 


Will earned his BS in biochemistry and molecular biology from Michigan Technological University in December of 2018. During this time, his research focused on understanding the diversity of an alkane-oxidizing gene in the microbial communities of the Great Lakes. Will is interested in answering astrobiological questions and, since the Fall of 2019, has been pursuing a PhD through the molecular biosciences program. His current research hopes to uncover the mechanisms behind the production of methane in oxic regions of freshwater lakes, known as the “methane paradox”, and to understand how impactful this phenomenon is on a global scale.

Zackary Jay, PhD                                               Researchgate profile     GoogleScholar profile


Zack earned his Ph.D. in Ecology & Environmental Sciences at MSU in the lab of William Inskeep where he researched microbial community structure and function in Yellowstone hot springs. He then did a postdoc with Ross Carlson (MSU) designing and building in silico, genome-scale stoichiometric metabolic models. Afterwards, he did a postdoc in the lab of Connie Chang (MSU) developing droplet microfluidic technology to understand influenza evolution at a single cell level. Prior to coming to MSU as a database expert for the NSF-funded Yellowstone Research Coordination Network, Zack earned his Masters in Biology from Northern Arizona University (NAU) in Flagstaff, AZ. There, he characterized genetic elements used to distinguish between highly-related strains of the causative agent of anthrax. He earned his B.S. in Microbiology Health Preprofessional with honors and a minor in Chemistry at NAU.

Stavros Trimmer​​    2nd year grad student                                 

                 

Stavros earned his B.S. in biochemistry from Colorado State University in 2022. As an undergraduate, he studied transcription regulation in the hyperthermophilic archaeon Thermococcus kodakarensis. In fall 2022, he began his Ph.D. at MSU through the Molecular Bioscience program. His research focuses on investigating the metabolic potential of Asgard archaea using both bioinformatic and culture-independent approaches. Asgard archaea are currently the closest relative to eukaryotes and encode a variety of eukaryotic-like proteins in their genome. Understanding their physiology will answer essential questions regarding how early pre-eukaryotic life might have evolved. 

Former lab members

Anthony McLean​​   1st year grad student     


Anthony graduated with a B.A. in biology from Grinnell College in 2017. After graduation, he worked as a research assistant for Dr. Jessica Mark Welch at the Marine Biological Laboratory and the Forsyth Institute studying the spatial ecology of the human oral microbiome. He started a Ph.D. in Microbiology in the Fall of 2023. His current research focuses on the physiology of members of the human gut microbiome.

Anthony Kohtz   6th year grad student                                                       Google Scholar Profile


Anthony earned his B.S. in microbiology and geology with a chemistry minor from the University of Nebraska-Lincoln in 2017. His undergraduate research covered topics ranging from rinded iron-oxide concretions found in Cretaceous sediments, to using Raman spectroscopy in studying microbe-mineral interactions in a methanogenic microbial consortia. Anthony studies the ecophysiology of uncultured microbes in geothermal features in order to establish the metabolic potential, substrate utilization, and biogeochemical roles of largely uncharacterized archaeal phyla. Additionally, he works on the development of new Raman microspectroscopy based approaches for enhanced visualization and cell-sorting of environmental taxa. Anthony will defend his PhD in July 2024 and plants to start a a postdoc with Chris Greening soon after.
