Siddhartha Jaiswal, MD, PhD

Dr. Jaiswal is an investigator at Stanford University in the Department of Pathology, where his lab focuses on understanding the biology of the aging hematopoietic system. As a postdoctoral fellow, he identified a common, premalignant state for blood cancers by reanalysis of large sequencing datasets. This condition, termed “clonal hematopoiesis,” is characterized by the presence of stem cell clones harboring certain somatic mutations, primarily in genes involved in epigenetic regulation of hematopoiesis. Clonal hematopoiesis is prevalent in the aging population and increases the risk of not only blood cancer, but also cardiovascular disease and overall mortality. Understanding the biology of these mutations and how they contribute to the development of cancer and other age-related diseases is the current focus of work in his lab. Dr. Jaiswal and colleagues’ studies use genetic and clinical information from large population-based cohorts to understand the impact of clonal hematopoiesis in humans. They also study the effect of the mutations causing clonal hematopoiesis in human and mouse tissues through a combination of genomic profiling, functional assays, and mouse models of disease.

Robert Lee, PhD

Dr. Lee is a research assistant professor at the University of North Carolina at Chapel Hill.

She obtained her doctoral degree in pharmacology and toxicology from Michigan State University, where she gained extensive training in evaluating mechanisms of cell death, inflammation, organ injury, and coagulation in animal models. In 2012, she joined the laboratory of Dr. Rafal Pawlinski at UNC for her postdoctoral research investigating the role of coagulation in SCD. Her studies revealed that tissue factor (TF), factor X (FX) and thrombin contribute to inflammation in mouse models of SCD. She has also been investigating the contact activation pathway in SCD, and recently discovered that high molecular weight kininogen contributes to inflammation, nephropathy, and early mortality in sickle mice. Most recently, Dr. Sparkenbaugh found that the TF-FXa-thrombin pathway contributes to microvascular stasis in sickle mice, likely via thrombin-dependent activation of protease activated receptor-1 (PAR-1). For her Scholar Award project, she will explore the effects of beneficial PAR-1 activation by activated protein C on the complications of SCD. Dr. Sparkenbaugh is grateful for the support provided by the ASH Scholar Award as she transitions to an independent research career.

Julia Warren, MD, PhD

Dr. Warren is a fellow in pediatric hematology/oncology at Washington University in St. Louis where her research focuses on understanding the genetics and molecular mechanisms of severe congenital neutropenia under the mentorship of Dr. Daniel Link. After completing undergraduate studies at the University of Chicago, Dr. Warren joined the MD/PhD (MSTP) program at Washington University where she completed her PhD in Immunology studying osteoclast cytokine receptor signaling with her thesis advisor Dr. Steven Teitelbaum. She then completed her internship and residency at St. Louis Children’s Hospital, pursuing the accelerated research pathway as part of the selective Oliver Langenberg Physician Scientist Training Program. Her work in the Link lab has focused on using exome sequencing to identify new genetic causes of SCN, and preliminary work has identified heterozygous variants in the mitochondrial protein caseinolytic peptidase B (CLPB). In cellular models using primary human cells and cell lines, Dr. Warren has demonstrated an increase in neutrophil progenitor cell apoptosis and evidence of mitochondrial dysfunction.  Future studies are aimed at identifying the mechanism underlying this mitochondrial dysfunction, and at understanding the relatively selective defect in granulopoiesis in contrast with patients who have extra-hematopoietic findings in the presence of biallelic CLPB variants.

Lena Winestone, MD

Dr. Winestone is an Assistant Professor in the Department of Pediatrics in the Division of Allergy, Immunology, and Blood & Marrow Transplant at the 
University 
of California San Francisco. She earned her MD from the Stanford University School of Medicine and went on to complete her residency in pediatrics at Lucile Packard Children’s Hospital at Stanford. She then completed her fellowship in pediatric hematology/oncology at the Children’s Hospital of Philadelphia.  She also obtained a Master’s in Health Policy Research at the University of Pennsylvania Perelman School of Medicine. She carried out her postdoctoral research in the clinical epidemiology research group of Dr. Richard Aplenc and her work focused on disparities in initial presentation with pediatric acute myeloid leukemia. Dr. Winestone’s research agenda continues to focus understanding the mechanisms underlying racial, ethnic, and socioeconomic disparities in access and outcomes for pediatric oncology patients. Her work has been presented in several oral presentations at the ASH annual meetings. Dr. Winestone participated in the ASH Clinical Research Training Program in 2016. The research on access to care within pediatric leukemia that the ASH Scholar Award is supporting stemmed from the mentorship she received during CRTI. Her mixed methods approach involves interviewing patients’ families, gathering quantitative survey and geographic data related to barriers to care, and multilevel modeling of the contribution of SES to access to care. Her long-term goal is to ameliorate existing cancer disparities and promote health equity across the populations we care for.  In addition to her research endeavors, Dr. Winestone attends on the blood and marrow transplant service at UCSF Benioff Children’s Hospital.

Andrew Yee, PhD

Dr. Yee is an assistant professor of Pediatrics at Baylor College of Medicine.  He received his PhD in chemical engineering from Rice University where he studied endothelial responses to mechanical forces in the laboratory of Dr. Larry McIntire. He then joined the laboratory of Dr. David Ginsburg at the University of Michigan as a postdoctoral fellow where he investigated the relationship between von Willebrand factor (VWF) and coagulation factor VIII (FVIII). Dr. Yee and his colleagues identified a minimal VWF fragment that stabilized circulating FVIII in the setting of complete VWF deficiency and located the primary interface between VWF and FVIII with an initial structure of the complex. With the ASH Scholar award, Dr. Yee continues to investigate VWF biology using molecular approaches to determine the mechanisms by which intrinsic and extrinsic dysregulations of VWF may disrupt hemostasis.
