Platelet activation plays a central role in thrombosis and hemostasis, while these processes are central to vascular health and disease. In the platelet lineage, bone marrow stem cells develop into early committed megakaryocyte progenitors, which undergo a unique cell cycle leading to polyploid cells prior to fragmenting into platelets. Our research focuses on mechanisms that regulate these processes under normal conditions vs. pathology. We proposed a new paradigm for controlling the transcription of genes uniquely expressed in this lineage, by identifying a cluster of non-tissue specific transcription factors that, together, constitute a signature uniquely driving this lineage development, among other cell lineages in the bone marrow. Studies were extended to identifying mechanisms governing polyploidy in megakaryocytes, leading also to better understanding of regulatory processes that cause polyploidy in other cells, such as aging vascular smooth muscle cells. Past projects involved molecular characterization of platelet and vascular adenosine receptors, and exploration of their roles in such cellular function. Importantly, knowledge gained by studying basic regulatory processes in healthy megakaryocytes and platelets aids our investigation of bone marrow pathologies, such as myeloproliferative neoplasms (MPNs). The systems used include primary bone marrow cultures, as well as transgenic and knock out mouse models.

Diversity, Equity, Inclusion and Accessibility

Commitment to inclusion, justice and excellence has been at the core of my professional and personal life. Diversity has been shown in various forums to contribute to creativity, mutual enrichment and collaborative building. Over the years, I have taken steps to contribute to enhanced diversity in our academic community in several ways, such as: 1. In the context of directly promoting interdisciplinary research related to health equity, I am currently (2022) the Director of a newly funded American Heart Association Center focused on the study of “Cancer-Associated Thromboembolism as Affected by Health Disparities (CAT-HD)”; 2. Affinity Research Collaborative groups within the Evans Center for Interdisciplinary Biomedical Research, which I direct, work on engaging patients and community members from underserved populations; 3. I participate as Subject Matter Expert on "Expanding Interdisciplinary Research" at the Northeast Faculty Leadership Program: Faculty Success through Diversity (NFLP), a leadership program for senior faculty of color funded by the Alfred P. Sloan Foundation, including tenured, underrepresented STEM faculty from ten area universities: Boston University, Harvard University, Northeastern University, Salem State University, Suffolk University, Tufts University, University of Connecticut, University of Massachusetts Boston, Wellesley College, and Wheaton College (Principal Investigator: Debra L. Franko, Ph.D., Northeastern University); 4. In my own laboratory, and through my leadership roles, I have served as a mentor to pre- and post-doctoral fellows and junior faculty of minority populations, who continue to propel the messages of research excellence and inclusion; 5. Within the Cardiovascular Biology NIH-funded training program that I directed for nearly 2 decades at BUSM, I made sure to provide opportunities to students of minority populations, with 20% of our trainees self-identifying as Hispanic or Black, and 50% as females; 6. As past member of admissions committees at BUSM, I participated in granting full attention to evaluating trainees from underserved communities; 7. The problems of inequity and bias can often be gender-based. Through my leadership roles, I have encouraged women researchers (trainees and faculty) to believe and achieve. Most of my past mentees are holding faculty and research leadership positions, nationwide and internationally.
