Nancy Braverman, MD, MS

GFPD Scientific Advisory Board Co-Chair 
| McGill University

Nancy Braverman received her undergraduate degree from Cornell University, Ithaca, NY, and MS in genetic counseling from Sarah Lawrence College in Bronxvillle NY. She received an MD from Tulane University in New Orleans, LA.

She completed a pediatric residency at Yale University, New Haven, CT and then a fellowship in genetics at Johns Hopkins University, Baltimore, MD., where she became involved in peroxisome disorders.

After 15 years at Johns Hopkins, she was recently recruited to McGill University in Montreal in order to focus more time on peroxisome research.

Michael Wangler, MD, MS

GFPD Scientific Advisory Board Co-Chair 
| Baylor College of Medicine

Michael Wangler is interested in improving understanding and treatments of rare inherited disease, and in the diagnosis and treatment of genetic disorders.

He is particularly motivated to study peroxisomal disorders because their pathogenesis is not understood, making them effectively untreatable.

He has undertaken an effort with Hugo Bellen, an expert in Drosophila neurobiology and genetics at the Texas Children’s Neurological Research Institute, to understand the biology of peroxisomal biogenesis in Drosophila melanogaster. With additional cases emerging from whole exome sequencing at Baylor, including phenotypes that have not been previously reported in association with peroxisomal gene mutations, they aim to combine fly and human studies to better understand these rare previously undiagnosed disorders.

Mousumi Bose, PhD

Montclair State University

Mousumi Bose is the mother of Ilan Betzer (2010-2011), who was born with a severe form of PBD-ZSD. Through her experience with her son, Dr. Bose joined the GFPD as the Medical and Scientific Research Liaison in 2012. Her work with the GFPD has resulted in the first GFPD research grant cycle as well as the first treatment guidelines for PBD-ZSD, which has shown to be an invaluable resource for families affected by PBD-ZSD.

Recently, Dr. Bose accepted a position at Montclair State University in New Jersey as an Assistant Professor in the Department of Nutrition and Food Studies. Her long-term goal is to conduct patient/family-centered research in rare metabolic diseases such as PBD-ZSD. 

Dr. Bose is passionate about continuing to learn about PBD-ZSD and other rare diseases and helping other rare disease families by using her knowledge and experience.

Mei Baker

Mei Baker, MD, FACMG

University of Wisconsin School of Medicine

Mei Baker, MD, FACMG is a professor in the Department of Pediatrics, and Co-Director in the Newborn Screening Laboratory at the University of Wisconsin School of Medicine and Public Health.

Dr. Baker practiced medicine before being trained in both biochemical and molecular genetics, obtaining a clinical biochemical genetics certification from the American Board of Medical Genetics and Genomics in 2009.

She has more than 10 years of experience in routine newborn screening (NBS) with specific interest in, and a successful track record of, applying emerging technologies to implement new screening tests for disorders and to improve ongoing screening tests. She is one of the leading scientists who made Wisconsin the first state in the nation to implement universal NBS for severe combined immunodeficiency (SCID) in 2008.

Dr. Baker is a principal investigator for an ongoing NIH/NICHD funded project for “Establishing a Newborn Screening Process for Early Identification and Treatment of Infants with Pompe Disease”. She is currently responsible for cystic fibrosis NBS using next generation sequencing technology. Dr. Baker is currently a member of the Advisory Committee on Heritable Disorders in Newborns and Children, chaired for the NewSTEPs Steering Committee.

Our community of researchers span the globe. We are very fortunate to have very talented and dedicated individuals in the PBD-ZSD research community.
