Dr. Will’s ascension marks a significant milestone for the institute, as she becomes the first permanent director following the founding leadership of Paul Frenette, M.D., Ph.D., whose groundbreaking work laid the foundation of the institute’s excellence. Her appointment comes after an extensive national search, acknowledging her outstanding contributions not only in research but also in mentorship and academic stewardship. Yaron Tomer, M.D., the Marilyn and Stanley M. Katz Dean and chief academic officer at Montefiore Einstein, highlighted Dr. Will’s demonstrated scientific excellence and her commitment to education, which collectively position her as the ideal leader for the institute’s next chapter.

The Gottesman Institute has long been a beacon for pioneering research into stem cell function, tissue regeneration, and the pathogenesis of complex diseases. Under Dr. Will’s guidance, the institute is expected to bolster integrative investigations focusing on chronic degenerative disorders such as dementia, diabetes, pulmonary diseases, immune deficiencies, and bone marrow failure. These conditions, which often have multifactorial etiologies and involve systemic deterioration, present formidable challenges that require innovative therapeutic approaches grounded in fundamental stem cell biology.

Dr. Will’s laboratory, funded by the National Institutes of Health, delves deeply into the molecular and cellular mechanisms governing hematopoietic stem cells (HSCs), which are responsible for lifelong blood regeneration. Her work has illuminated critical signaling pathways that enable these adult stem cells to maintain their regenerative capacity and adapt to the physiological demands imposed by aging and cancer. Discovering these pathways not only enhances our understanding of stem cell biology but also opens avenues for developing targeted therapies that can rescue or amplify stem cell function.

One of the transformative aspects of Dr. Will’s research is the identification of cellular mechanisms that become compromised during aging and malignant transformation. By unraveling how these mechanisms influence HSC exhaustion or dysregulation, her team aims to discover pharmacological interventions that could improve stem cell engraftment during transplantation, combat hematopoietic failure syndromes, and suppress leukemic progression. These insights hold substantial promise for enhancing clinical outcomes in oncology and regenerative medicine.

Dr. Will’s expertise extends beyond her research lab as she assumes a central role in cancer biology and preclinical research within the Montefiore Einstein Comprehensive Cancer Center (MECCC). As co-leader of the stem cell biology and cancer biology program and director of the cancer stem cell pharmacodynamics laboratory, she integrates mechanistic investigations with translational science aimed at refining therapeutic regimens for hematologic malignancies. Her leadership ensures that laboratory discoveries are rapidly and efficiently translated into clinical trials that redefine patient care standards.

A key component of Dr. Will’s vision is fostering interdisciplinary collaboration, leveraging the strengths of physicists, biologists, clinicians, and data scientists to innovate complex models of disease and regenerative potential. By nurturing such alliances, the institute is poised to develop systems biology frameworks capable of predicting stem cell behavior in response to therapeutic interventions and aging-related stressors, thereby accelerating the bench-to-bedside pipeline.

Beyond her scientific and administrative achievements, Dr. Will’s dedication to education and mentorship is profound. She has played an instrumental role in training the next generation of biomedical researchers by serving on various admissions committees and supporting predoctoral and postdoctoral fellows. Her commitment to diversity and inclusion is particularly notable, as she actively engages with programs designed to inspire young scientists from underrepresented communities, including those from the Bronx, to pursue careers in cutting-edge biomedical science.
