Hans Ackerman, M.D., D.Phil., M.Sc.

Lasker Clinical Research Scholar; National Institute of Allergy and Infectious Disease

Website:

Hans Ackerman became a Lasker Scholar in 2014. He is studying sickle-cell disease and malaria, which share an evolutionary link and many of the same disease-causing mechanisms that underlie vascular dysfunction. He is also studying how naturally occurring genetic differences change nitric-oxide signaling and vasodilation responses in blood-vessel walls. He hopes his work will contribute to the development of drugs that could prevent or treat the vascular complications of sickle-cell disease or malaria. He received his M.D. degree from Harvard Medical School (Boston), and his D.Phil. in human genetics and M.Sc. in biological anthropology from the University of Oxford in England. He completed a residency in internal medicine at the Massachusetts General Hospital (Boston); a fellowship in critical-care medicine at the NIH Clinical Center; and a research fellowship at the Laboratory of Malaria and Vector Research in the National Institute of Allergy and Infectious Diseases. He and his wife enjoy raising their three boys.

Sean Agbor-Enoh, M.D., Ph.D.

Lasker Clinical Research Scholar, Laboratory of Applied Precision Omics, National Heart, Blood, and Lung Institute

Website: ��

Sean Agbor-Enoh, who became a Lasker Scholar in 2019, is developing genomic methods for the early detection and treatment of lung-transplant rejection. His method—which can detect rejection two to three months earlier than the current invasive process of taking a lung-tissue biopsy after rejection has begun—involves a simple blood test that measures cell-free DNA in the bloodstream. “My hope is to bring innovative and cutting-edge approaches to improve survival after lung transplantation,” he said. He received his M.D. from the University of Yaoundé (Yaoundé, Cameroon) and a Ph.D. in molecular biology from Georgetown University (Washington, D.C.). He did a postdoctoral fellowship at Georgetown University Medical Center; a residency and chief residency in internal medicine at Johns Hopkins Bayview Medical Center (Baltimore); a fellowship in critical care medicine at the NIH Clinical Center; and a fellowship in pulmonary medicine at Johns Hopkins Hospital (Baltimore). Outside of work he loves to explore nature’s treasures with his wife and four children, who range in age from 2 to 17.

Christine Campo Alewine M.D., PH.D.

Lasker Clinical Research Scholar, Laboratory of Molecular Biology, Center for Cancer Research, National Cancer Institute

Website:��

Christine Campo Alewine��became a Lasker Scholar in 2016. She is conducting clinical trials to test the effectiveness of a recombinant immunotoxin in combination with standard-of-care chemotherapy in patients who have advanced pancreatic cancer. Recombinant immunotoxins are antibody-based anticancer therapeutics that deliver a potent bacterial toxin to cancer cells; the toxin halts protein synthesis in those cells. Her study may lead to advances in our understanding of whether immunotoxins can be used to treat pancreatic cancer and provide insight into technical aspects of this therapeutic strategy. Alewine received her Ph.D., in physiology, and M.D. from the University of Maryland School of Medicine (Baltimore). She completed a residency in internal medicine at Johns Hopkins Hospital (Baltimore) and a clinical fellowship in medical oncology at NCI’s Laboratory of Molecular Biology. Her outside activities include tennis, hiking, quilting, being a Girl Scout troop leader, and spending time with her husband and their two daughters.

Alison Boyce, M.D.

Lasker Clinical Research Scholar, Metabolic Bone Disorders Unit, National Institute of Dental and Craniofacial Research

Alison Boyce, who became a Lasker Scholar in 2020, is searching for treatments for fibrous dysplasia/McCune-Albright syndrome (FD/MAS), a rare and debilitating skeletal disease that can cause bone fractures, deformity, pain, and loss of ambulation, vision, and hearing. Emerging evidence suggests that the receptor activator of a protein called RANKL, which regulates bone resorption, plays a role in FD pathogenesis. Boyce is investigating whether inhibiting RANKL would serve as a novel therapeutic strategy to treat patients. She received her M.D. from Eastern Virginia Medical School (Norfolk, Virginia); did a residency in pediatrics at Children’s Hospital of the King’s Daughters (Norfolk, Virginia); and completed a fellowship in pediatric endocrinology at the National Institute of Child Health and Human Development.

Website:��

Courtney Fitzhugh, who became a Lasker Scholar in 2016, is seeking to improve—and develop new—treatment options to achieve a cure for sickle-cell disease (SCD). Although matched-sibling bone-marrow transplantation offers the best treatment for people with SCD, only 15 to 20 percent of these patients have a complete sibling match. More than 90 percent have at least a half-match such as a parent, child, or half-matched siblings. Fitzhugh is developing an alternative option that involves such haploidentical donors. Her goal is to develop a widely available, successful half-matched transplant regimen. She received her M.D. from the University of California, San Francisco, School of Medicine; did a combined residency in internal medicine and pediatrics at Duke University Medical Center (Durham, North Carolina); and a combined fellowship in adult hematology and pediatric hematology/oncology, at NIH and Johns Hopkins Hospital (Baltimore). In her spare time, she enjoys cooking, traveling, playing board games, and watching movies.

Murphy Children’s Hospital (Falls Church, Virginia). At NIH, her clinical research focuses on microbiome interventions to mitigate chronic inflammatory diseases. She has an ongoing 600-subject randomized placebo-controlled clinical trial of the microbiome intervention, “vaginal seeding” (transferring the mother’s vaginal microbiome to the newborn), in babies born by cesarean section. Cesarean delivery is associated with a higher risk of a child developing chronic inflammatory conditions associated with the microbiome, including obesity, which she hopes to mitigate with vaginal seeding. Hourigan also leads studies investigating other microbiome interventions including fecal transplant and early-life antibiotics. She received her medical degree from the University of Oxford (Oxford, England) and completed a pediatric residency and pediatric gastroenterology fellowship at Johns Hopkins Hospital (Baltimore).

Natalie D. Shaw, M.D. M.M.Sc. (2015)

Lasker Clinical Research Scholar, Clinical Research Branch/Pediatric Neuroendocrinology Group, National Institute of Environmental Health Sciences

Website:��

A 2015 Lasker Scholar, Natalie Shaw is interested in determining the physiologic and pathophysiologic underpinnings of irregular menstrual cycles among adolescent girls. Although irregular menstrual cycles are a common part of female development, a subset of teens never make the critical transition to normal menstrual cycles. By investigating the mechanisms underlying irregular cycles after the first menses, including potential genetic and environmental contributors (such as body weight and sleep structure and duration), she hopes to identify girls at high risk for future hormonal and metabolic complications who deserve early treatment. Shaw received her M.D. from the University at Buffalo State University of New York Medicine and Biomedical Sciences (Buffalo, New York) and her M.M.Sc. from Harvard Medical School (Boston). She then did a residency in pediatrics at the Children’s Hospital of Pittsburgh (Pittsburgh); a clinical fellowship in pediatric endocrinology at Children’s Hospital Boston (Boston); and a research fellowship in reproductive endocrinology at Massachusetts General Hospital (Boston). Before coming to the NIH, she was an assistant professor in pediatrics at Harvard Medical School and an attending physician in pediatric endocrinology at Children’s Hospital Boston.

Marielle E. Yohe, M.D., Ph.D.

Lasker Clinical Research Scholar, Laboratory of Cell and Developmental Signaling, and Adjunct Investigator, Pediatric Oncology Branch, Center for Cancer Research, National Cancer Institute

Website:

Marielle Yohe, who became a Lasker Scholar in 2021, studies the RAS/MAPK pathway, which is frequently dysregulated in several pediatric solid tumors (such as rhabdomyosarcoma and neuroblastoma) and RASopathies (such as Costello Syndrome). RASopathies are caused by genetic mutations that encode components or regulators of the Ras/mitogen-activated protein kinase (RAS/MAPK) pathway.
