Postdoctoral Associate

Postdoctoral Associate Trowbridge Lab Bar Harbor, ME A Postdoctoral Associate position is available in Dr. Jennifer Trowbridge's laboratory at The Jackson Laboratory in Bar Harbor, Maine. The Trowbridge lab is dedicated to uncovering the fundamental mechanisms that govern hematopoietic stem cell (HSC) biology across three interconnected areas: HSC aging

• both the cell-intrinsic changes that accumulate over a lifetime and alterations that occur in the bone marrow microenvironment where these cells reside Clonal hematopoiesis
• understanding why somatic mutations in epigenetic regulatory genes (e.g., DNMT3A, TET2, ASXL1) are selectively expanded in HSCs with aging, and how they modify risk of aging-associated diseases Hematologic malignancies
• the mechanisms by which clonal hematopoiesis progresses to myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) Our long-term goal is to identify intervention strategies that extend "healthspan" of blood stem cells
• preserving their regenerative capacity into older age and reducing the risk of blood cancers.

The multi-disciplinary nature of our work is highlighted our recent publications in Nature Communications (Young et al., 2025) and Nature (Hosseini et al., 2025) identifying elevated mitochondrial metabolism as a selective dependency of CH-mutant HSCs. The Trowbridge lab offers a highly collaborative environment with strong national and international collaborations. Past and current trainees have been extremely successful in obtaining competitive grant funding and fellowships, and have gone on to independent positions in both academia and industry. Responsibilities The successful candidate will be able to plan, develop, execute, and analyze an independent research project within one or more of the lab's focus areas. Additional responsibilities include preparing manuscripts, fellowship applications, and conference presentations, mentoring junior lab members and contributing to a collaborative team environment. Required Qualifications M.D. or Ph.D. in biological or related sciences Minimum of one first-author publication from graduate work Strong foundational training in molecular and cell biology Exceptional verbal and written communication skills Self-motivated and able to work independently as well as collaboratively Preferred Qualifications Experience or training in any of the following areas: Hematopoiesis, stem cell biology, aging, or immunology Epigenetics or chromatin biology Mouse HSC biology-related experimental techniques CRISPR-based approaches including gene editing in primary cells, sgRNA design, lentiviral delivery Computational biology/bioinformatics How to Apply A complete application must include a cover letter describing past research accomplishments, current research interests, and career aspirations; a current CV; and the names and contact information of three references.

Postdoc About JAX:

The Jackson Laboratory is an independent, nonprofit biomedical research institution with a National Cancer Institute-designated Cancer Center and nearly 3,000 employees in locations across the United States (Maine, Connecticut, California), Japan and China. Its mission is to discover precise genomic solutions for disease and empower the global biomedical community in the shared quest to improve human health. Founded in 1929, JAX applies over nine decades of expertise in genetics to increase understanding of human disease, advancing treatments and cures for cancer, neurological and immune disorders, diabetes, aging and heart disease. It models and interprets genomic complexity, integrates basic research with clinical application, educates current and future scientists, and provides critical data, tools and services to the global biomedical community.

EEO Statement:

The Jackson Laboratory provides equal employment opportunities to all employees and applicants for employment in all job classifications without regard to race, color, religion, age, mental disability, physical disability, medical condition, gender, sexual orientation, genetic information, ancestry, marital status, national origin, veteran status, and other classifications protected by applicable state and local non-discrimination laws.

Bar Harbor:

The Jackson Laboratory's 43-acre scenic Bar Harbor campus is nestled between the Gulf of Maine and the mountains of Acadia National Park. Some of the best hiking and biking in the world (over 50 square miles of mountains, lakes, views, and dramatic coastline) is accessible from our campus. We are one mile from downtown Bar Harbor, which offers a vibrant downtown district with a plethora of restaurants, shops, museums, and galleries.

Ellsworth:

The Charles E. Hewett Center in Ellsworth, Maine, is a state-of-the-art facility that serves researchers world wide. The facility represents the culmination of nine decades of unmatched experience and leadership in breeding and caring for laboratory mice. Ellsworth, Maine, is one of Maine's fastest growing cities. With a growth rate of nearly 20%, Ellsworth is a bustling year-round community and acts as a hub for surrounding towns. It is located nearby Acadia National Park and hosts numerous special events, concerts and festivals each year. Residents have access to fabulous shopping, recreation, museums, galleries, and dining at a variety of independent restaurants.

Farmington:

JAX Genomic Medicine is transforming medicine by improving patient care, lowering costs, and increasing life span and health span. JAX Genomic Medicine's research focuses on the complex genetic causes of disease and on the development of genomic solutions tailored to each person's unique genetic makeup. JAX Genomic Medicine sits on a 17-acre site on the campus of the University of Connecticut Health Center. The 183,500-square-foot facility opened in the fall of 2014. Now, it houses over 300 biomedical researchers, technicians, and support staff in state-of-the-art computing facilities and laboratories. In Connecticut, JAX resides in the scenic town of Farmington, in the state's capitol region. The Hartford region, which offers some of the best public schools in the country, is made up of both bigger cities and smaller, charming historic New England towns. JAX Genomic Medicine is also geographically located within 2 hours of Boston and New York and is close to multiple transportation systems, including bus lines, highways, railroads and international airports.

Sacramento:

The JAX® Mice, Clinical and Research Services facility is located in Sacramento, the state capital of California. Sacramento is less than a two-hour drive from San Francisco, Napa Valley, and scenic Lake Tahoe, and a short flight to both Los Angeles and Orange County. Sacramento is the birthplace of the nation's Farm to Fork movement, and offers excellent restaurants, gastro-pubs, wineries, theaters, and museums.

Outdoor activities are plentiful:

Boating, white water rafting, and riding the scenic bicycle trails are popular. Housing and other costs of living are more affordable in Sacramento and its surrounding suburbs than in most other neighboring areas in the North Bay, making Sacramento one of the hottest housing markets in the country year after year.

Augusta:

JAX's Maine Cancer Genomics Initiative (MCGI) is located in Augusta, Maine, in the Harold Alfond Center for Cancer Care (HACCC), at Maine General Hospital. It began operations in 2016 with three overarching goals: to provide cancer genomic testing for Maine cancer patients; to develop and deliver physician education about clinical genomic cancer diagnostics; and to build a network in Maine of oncology practices conducting studies in genomic medicine.
