Jennifer TrowbridgePrincipal Investigator

Jen received her BSc in Genetics and PhD in Microbiology & Immunology from The University of Western Ontario. Her postdoctoral training was with Stuart H. Orkin at the Dana-Farber Cancer Institute. Jen has received the Janet Rowley Award from the International Society for Experimental Hematology (ISEH), an American Society of Hematology (ASH) Scholar Award, the V Scholar Award and the Ellison Medical Foundation New Scholar in Aging Award. She is an Associate Professor at The Jackson Laboratory and at Tufts University School of Medicine.


Kira Young – Associate Research Scientist

Kira received her BS in Chemical Engineering and PhD in Functional Genomics from the University of Maine, and completed her postdoctoral training in the Trowbridge lab. Kira’s project focuses on understanding causative changes driving hematopoietic aging, particularly in terms of alterations in the hematopoietic cell-extrinsic bone marrow microenvironment. Kira was the recipient of fellowship funding through a JAX T32 training grant, a JAX Pyewacket fellowship award and the American Society of Hematology (ASH) Scholar award.


Jennifer Myers SanMiguel – Postdoctoral Fellow

Jen received her BA in Biology from Colby College and PhD in Cell and Molecular Biology from the University of Pennsylvania. Jen conducted her thesis work in the laboratory of Dr. Marisa Bartolomei studying the epigenetic regulator TET1 and its role during developmental epigenetic reprogramming. She joined the lab in August of 2018. Jen’s project focuses on understanding how clonal hematopoiesis-mutant HSCs are selected for during aging. Jen is the recipient of fellowship funding through JAX T32 training grants.


Logan Schwartz – Ph.D. candidate

Logan received her BS in Molecular Genetics from The University of Rochester and subsequently was a research technician with Drs. Christopher Ott and Jay Bradner at Massachusetts General Hospital and the Dana-Farber Cancer Institute. Logan is currently a PhD candidate in the Tufts Graduate School of Biomedical Sciences Genetics Program. She began her thesis work in the lab in June 2019. Logan’s project focuses on understanding how changes in the bone marrow microenvironment synergize with somatic mutations in HSCs to promote clonal hematopoiesis. Logan is the recipient of a Burroughs Wellcome Fund training fellowship from JAX and NIH F31 fellowship grant from the NIDDK.


Kristina Mujica – Research Assistant II

Tina received her BS in Wildlife Biology from Unity College and joined the lab as a Research Assistant in January 2019 with previous experience as an animal care technician here at JAX, and as a veterinary technician at an animal shelter. Since is currently pursuing a Masters’ degree from Johns Hopkins University. Tina’s project focuses on understanding how heritable genetic background modifies risk of clonal hematopoiesis. Email:

Abimbola Lawal – Research Assistant I

Abimbola received her Bachelor’s degree in Animal Science from the Federal University of Agriculture in Abeokuta, Nigeria. She joined the lab as a Research Assistant in 2021 with previous experience as an animal care technician at JAX. Abimbola manages our laboratory’s animal colony and supports experiments across the laboratory. Email:
