Ph.D. in Biomedical Engineering (Synthetic Biology), Michigan State University, 2022.
B.S. in Biochemistry/Molecular Biology, Michigan State University, 2018.


My research interests span the fields of synthetic biology, genomics, biochemistry, chemical engineering, applied biotechnology, environmental microbiology, bacteriotherapy, immunology. Current projects involve: 1) designing genetic control of nitrogen fixation that is responsive to several environmental stimuli which can be engineered into a chassis organism to be grafted into natural microbial communities for improved plant host growth and crop production; 2) characterizing microbial communities from several sources and developing high-throughput measures for understanding community dynamics which could be applied to several bioprospecting projects.
