Dr. Chau obtained her Bachelor of Science in Biomolecular Engineering from Santa Clara University in 2019 and her Ph.D. in Integrative Pathobiology from the University of California, Davis in 2024. Currently, she is a postdoctoral researcher at the Stanford School of Medicine, working under the mentorship of Dr. Glaivy Batsuli. Her research focuses on elucidating the innate immune response to factor IX (FIX) utilizing her expertise in bioinformatics to bridge gaps in the understanding of immune tolerance and reduce antigenicity in hemophilia B treatments.

Individuals with hemophilia B are susceptible to spontaneous and injury-induced bleeding events throughout their lives. Early diagnosis and initiation of factor IX (FIX) replacement therapy in individuals with a severe bleeding phenotype is critical for bleed prevention, managing bleeding episodes, and preventing the long-term occurrence of frequent bleeds. Roughly 3-10% of individuals with hemophilia B develop inhibitors that limit the hemostatic efficacy of FIX replacement and increases the risk of uncontrolled bleeding. In contrast to factor VIII (FVIII) inhibitor development in hemophilia A, individuals with hemophilia B and inhibitors have limited treatment options for inhibitor eradication due to the risk of hypersensitivity reactions, anaphylaxis, and nephrotic syndrome with FIX re-exposure. Despite extensive research into the immune response against FVIII, an in-depth understanding of mechanisms that define the immune response to FIX is lacking. Our research project aims to investigate the innate immune response pathway underlying the onset of FIX inhibitors. This project focuses on two aims: (1) defining the role of dendritic cell (DC) subsets in FIX inhibitor development and (2) identifying the cytokine signature, specifically IL-13, in this process. Expected outcomes of our study will contribute towards understanding FIX inhibitor development and potential therapeutic interventions.

Dr. Brake has a background in genetics, molecular biology, and biochemistry, with research experience spanning thrombosis genetics, publications in PNAS and JCI, and multiple academic awards. Currently a postdoctoral fellow at Beth Israel Deaconess Medical Center, Dr. Brake investigates the genetic regulation of tissue factor (F3) in hemostasis and cancer-associated thrombosis, while collaborating with the BioMe Biobank and aiming to eventually lead their own research lab.

This project is the first to study humans with a genetic deficiency in tissue factor, which activates the first step in the formation of blood clots. The goal is to understand how this deficiency changes the baseline amounts of byproducts produced from the blood clotting pathway, and whether these individuals have an increased risk of bleeding.

Louise Baca, MSN, RN, has over 40 years of healthcare experience, primarily specializing in oncology. She has worked in various settings, including inpatient oncology, outpatient infusion, clinical research, and as a nursing instructor. For the past 14 years, she has served in an administrative role, currently as Senior Director at Maine Medical Center, where she leads the MaineHealth Bleeding Disorders program. Under her leadership, the program has grown significantly, expanding from 2.5 to 15 FTEs and enhancing patient care in Maine and New Hampshire. Louise also serves on several committees, including the Hemophilia Alliance Board of Directors and the New England Regional Executive Committee, and has presented nationally on healthcare topics.

This project is a nurse led project (APNs and RN’s) and focuses solely on developing relationships with nurses and other clinicians in rural areas. As the only HTC in the state, it is the responsibility of the MaineHealth Bleeding Disorder nurses to educate other nurses in rural parts of Maine who will be the first point of contact. This work will create a blueprint for nurses, providing them with comprehensive information and practical ideas that can easily be implemented and assist them in caring for patients living in rural areas. These successful strategies will allow for the sharing of best practices ultimately elevating the standard of nursing care across all HTCs.

People with hemophilia receive regular clotting factor infusions in order to prevent bleeds, as well get routine blood draws during clinic visits. Vascular access can be difficult in children with hemophilia and can become a stressor, impacting compliance with medication schedules and attitudes toward healthcare systems and procedures. This project aims to explore the impact of exercise on the ease of vascular access. We hope to show that regular exercise, as well as exercise immediately before an infusion/blood draw, will make accessing veins easier. We will also collect data on the impact of our protocol on fear of needles and fear of movement/exercise, in hopes that easier vascular access will decrease fear.  

Bhavya Doshi, MD, is a pediatric hematologist and just accepted a new faculty position at Emory University in Atlanta, GA where the hemophilia group has been well-established in the study of factor VIII inhibitors. Dr. Doshi specializes in caring for children with bleeding and clotting disorders. She completed her medical training and pediatric residency at Emory University School of Medicine in Atlanta, GA and her pediatric hematology/oncology fellowship at the Children’s Hospital of Philadelphia. Dr. Doshi is a physician scientist with expertise in basic and translational approaches to improving diagnostics and therapeutics for patients with bleeding and clotting disorders. Her laboratory conducts research focused on the development, persistence, and management of neutralizing antibodies to protein replacement therapy and gene therapy in hemophilia. Her work has identified hemophilia A patients with anti-factor VIII antibodies who may be amenable to alternative treatment modalities whether bypassing agents or immunosuppressive regimens. Dr. Doshi’s work aims to identify B cell signatures that are altered in patients with alloantibody responses to therapeutics and leverage these for therapeutic development.

Our research focuses on understanding why some people with hemophilia A develop inhibitors that make treatment less effective, especially with new non-factor therapies. We aim to uncover how certain immune responses, like cytokine and cell activity, contribute to the development of these inhibitors. Specifically, we are studying a protein called BAFF and its role in influencing immune cells, though it’s still unclear what causes high BAFF levels. Our findings could lead to new biomarkers and treatments for preventing inhibitor development.

I received by BS in Biochemistry from the University of Arizona in 2012. I then received my PhD at the University of Maryland, Baltimore County while studying under Dr. Elsa D. Garcin. I am currently a postdoctoral scholar at Western Washington University under Dr. P. Clint Spiegel. Our research focuses on the structure/function of activated coagulation factor VIII and factor IX and how the two proteins bind to lipid membranes to form the intrinsic tenase complex. The results from this research will elucidate the mechanism behind hemophilia A/B-associated missense mutations and how factor replacement therapeutics can be rationally designed for increased pharmacokinetic properties.

Tomasz received his Pharm.D. degree in 2019 in Pharmacology and Toxicology science from Medical University of Bialystok, Poland, and immediately started his postdoctoral appointment at Vascular Medicine Institute at the University of Pittsburgh, PA. Tomasz's research focuses on the innate immune mechanisms in platelets and neutrophils as well as thrombo-inflammation pathophysiology. He uses cutting-edge intravital microscopy techniques to image in real-time the interplay between neutrophils and platelets during the initial stages of immune system activation. His work has authentic interdisciplinary nature since he studies cross-talk between innate immune signaling in neutrophils, Factor VIII deficiency, liver diseases and macroscale proteomics and genomic profiles of neutrophils and platelets under inflammatory stress. Until now, he proved that neutrophil activation seems to be a key player in the hemophilic arthropathy progression, dedifferentiated sinusoidal endothelium impacts liver-directed gene transfer in Hemophilia-a mice, and that liver to lung microemboli NETs promote Gasdermin-D-dependent inflammatory lung injury in Sickle Cell Disease. Tomasz has been appreciated with multiple awards from national and international societies and institutions as well as his research activities were supported by numerous extramural funding sources. In his scientific and personal life, he proudly follows the University of Pittsburgh's motto - Veritas et Virtus.

My commitment to sickle cell disease (SCD) research started early during my medical career, driven by a magnificent opportunity to actively participate in the conduction of the SACRED study (Stroke Avoidance for Children in República Dominicana). This clinical trial aims to investigate the use of transcranial Doppler ultrasound screening and hydroxyurea therapy for stroke prevention in pediatric patients with SCD. Today, SACRED is the largest and most important research study involving SCD in the Dominican Republic (my home country).

This experience fueled in me a strong purpose to better understand blood disorders, particularly SCD, and how to improve outcomes for individuals with this condition. I completed my Pediatric Residency at Cincinnati Children’s Hospital and my Pediatric Hematology/Oncology Fellowship at Texas Children’s Hospital. Training under the mentorship of international leaders in the field of pediatric hematology, allowed me to continue to gain clinical experience while expanding my scholarly pursuits and interest in clinical research. I am now a Sickle Cell specialist at Indiana Hemophilia and Thrombosis Center. With the support of the JML Fellowship, I am investigating the clinical and hematopoietic profiles of children with SCD associated with a sustained induction of fetal hemoglobin response to hydroxyurea treatment. The results of this project may help predict hydroxyurea response, allowing a more individualized approach to treatment of both pediatric and adult patients with SCD.

His project aims to directly address current limitations of hemophilia A gene and protein therapy by the identification and characterization of new hyperactive factor VIII variants based on his previous studies of hyperactive factor IX variants. He will take a rational approach to identify such variants focused on amino acid substitutions that can enhance factor VIII cofactor activity while maintaining physiological regulation, which will facilitate their translation into therapeutics. In vivo murine studies of efficacy and immunogenicity will provide the basis for subsequent translational studies.
