Postdoctoral Associates

Beth received her undergraduate degree in Biology from McMaster University in Ontario, Canada and continued on to her PhD at McMaster where she did antibiotic discovery and infectious disease research under the supervision of Prof. Gerry Wright. Shifting her focuse towards the microbiome, she joined Andy Goodman's lab in 2021 for her postdoctoral training.

I received my undergraduate degree in Biochemistry from Michigan State University, where I worked in the laboratory of Dr. Christoph Benning studying lipid biosynthesis in the green algae Chlamydomonas reinhardtii. I completed my Ph.D. training in the laboratory of Dr. Rey Carabeo studying novel mechanisms of gene regulation in the obligately intracellular bacterium, Chlamydia trachomatis, during which I was awarded an F31 training grant through NIAID. This experience cultivated my continued interest in how pathogens sense and respond to their environment, particularly during infection. I therefore chose to pursue a postdoctoral position at the Yale School of Medicine in the laboratory of Dr. Eduardo Groisman studying how the model bacterial pathogen Salmonella governs central metabolic functions during nutritional stress conditions relevant to infection. In my spare time, I enjoy reading, hiking and exploring dog parks with my canine companions.

Dr. Tachiyama earned his Ph.D. in Biochemistry and Biophysics at the University of Kansas in 2020. In his Ph.D. projects, he used biophysical and microbiological approaches to research molecular functions and protein interactions in the cytoplasmic side of the Shigella type III secretion system. In 2020, he joined Dr. Jun Liu’s laboratory at Yale as a Postdoctoral Associate and has continued to research Shigella T3SS using in situ experiments. This research project is conducted in collaboartion with Dr. William Picking, University of Kansas. Dr. Tachiyama’s research also focuses on structural details of flagella in Helicobacter pylori using the in situ approaches, and this project is being conducted in collaboration with Dr. Timothy Hoover, University of Georgia.
