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. Email:

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. Email:

Jayna Mistry – Postdoctoral Fellow

Jayna received her BSc (Hons) from Aston University and her PhD from the University of East Anglia and Earlham Institute in the UK. She conducted her thesis work in the laboratory of Dr. Stuart Rushworth studying the role of metabolism in stress hematopoiesis. Jayna’s focus is on understanding aging-associated mechanisms of Dnmt3a-mutant clonal hematopoiesis. Jayna is a current recipient of a JAX Scholar Award. Email:


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. 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. Email:


Kristina Mujica – Research Lab Associate Manager

Tina received her BS in Wildlife Biology from Unity College and Masters degree from Johns Hopkins University. Prior to joining the lab, Tina had previous experience as an animal care technician here at JAX, and as a veterinary technician at an animal shelter. Tina serves as our laboratory manager for day-to-day operations, coordinates our animal colony, trains incoming lab members, and supports experiments across the laboratory. Email:

Patricia Colom Díaz – Postbacc Fellow

Patricia received her Bachelor of Science in Biology from the University of Puerto Rico. She joined the postbacc program having had laboratory experience in genetics research and STEM mentoring experience with high school students. Patricia’s project focuses on drug sensitivity and resistance mechanisms in clonal hematopoeisis and leukemia. Patricia aspires to pursue an MD or MD-PhD degree following completion of her postbacc position. Email:

Griffin Nye – Research Assistant II

Griffin received his Bachelor of Science in Biomedical Science from the University of New Hampshire with experience in microbial research. Griffin supports experiments across the laboratory in the areas of clonal hematopoiesis, inflammation and metabolic regulation. Email:

Brandon James – Research Assistant I

Brandon received his Bachelor of Science in Biology from Delaware Valley University, where he was selected into the DelVel Honors Program and ALD Honors Society. Brandon supports experiments across the laboratory, particularly focused on a project to discover of methylation-independent functions of mutant Dnmt3a in driving clonal hematopoiesis. Brandon aspires to return to school to pursue an MD-PhD program. Email:

Nathan Boyer – Research Technologist

Nathan received his Bachelor of Science in Biochemistry with a minor in statistics from the University of Vermont with experience in molecular biology, bioinformatics, and cell culture. Nathan supports experiments across the laboratory in the areas of advanced mouse modeling, aging, clonal hematopoiesis and tissue regeneration. Email:
