Kristopher Kieft

Current Position: Computational Scientist at Moderna Genomics

Ph.D, Microbiology Doctoral Training Program (2017-2022)

Research – Kris joined the lab in 2017 and was the first graduate student in the laboratory. During his PhD, Kris explored ecological and biogeochemical services of phages in nature and the human gut. He also led the development of several bioinformatic methods to expand the set of tools available for investigating phages including VIBRANT, vRhyme, and Propagate. Kris graduated in May 2022.

Jacob Hotvedt

Current Position: Microbiology PhD Student at UW-Madison in the Sperandio Lab

M.S. Bacteriology, University of Wisconsin-Madison (2020-2022)

Research – Jacob joined the lab in 2020 and studied the role of organic sulfur compounds in the production of hydrogen sulfide in nature. He developed HPLC based approaches to measure organic sulfur compounds (amino acids such as cysteine) and experimentally demonstrated the microbial degradation of organic sulfur compounds in freshwater bacterial model systems.

Patricia Tran

Current Position: Bioinformatics Scientist in the Department of Bacteriology, University of Wisconsin-Madison

Ph.D, Freshwater and Marine Sciences Program (2018-2023)

Research – Patricia joined the lab in 2018 and studied freshwater microbiology and virology. During her PhD, Patricia explored the metabolism and ecology of microbes in anoxic zones of freshwater lakes, such as seasonally oxygen-depleted bottom waters (hypolimnions) of Lake Mendota (Madison, WI), and the permanently anoxic deep waters of Lake Tanganyika (Tanzania). She also contributed to several bioinformatics projects including METABOLIC and led the study of microbial sulfur metabolism in freshwater lakes.

Elise Cowley

Current Position: Completing her MD-PhD program at University of Wisconsin-Madison

Ph.D, Microbiology Doctoral Training Program (2020-2023)

Research – Elise joined the lab in 2020 and studied human microbiomes and viromes. Her research focused on diverse microbiome-driven disorders such as colorectal cancer, multiple sclerosis, and group B streptococcus. Specifically, her research has identified strong associations at the genomic and genetic resolutions between microbial sulfur metabolism and colorectal cancer.
