Dr. Brayton received her D.V.M. from Cornell University, and did postdoctoral research and pathology training in New York City at the Animal Medical Center, Cornell University and The Rockefeller University.  At The Rockefeller University (1989-1992), she became specifically interested in the pathology and characterization (phenotyping) of genetically engineered mice (GEM), and continued to pursue this interest at several institutions while heading the Facility for Comparative Studies at the Hospital for Special Surgery (1992-1998).  At Baylor College of Medicine (1998-2004), she headed the Comparative Pathology Laboratory, and was responsible for health surveillance and diagnostic pathology for a diverse research population including more than 150,000 mice.  She also was associate professor in pathology, associate director of the Center for Comparative Medicine, interim attending veterinarian, and served on the IACUC, while pursuing research collaborations, teaching initiatives, and developing national and international conferences on the characterization and pathology of genetically engineered mice. 

In 2004 she moved to Johns Hopkins to develop a collaborative phenotyping core based in the Department of Molecular and Comparative Pathobiology (MCP), where veterinarian faculty investigators and trainees provide a unique comparative and translational research resource, in an institution with exceptional resources for multidiscipinary biomedical research.  The core supports research with about 100 investigators per year.

Current Roles

The  Phenotyping Core aims to facilitate interdisciplinary phenotyping and translational research collaborations, and offers preclinical research pathology support and collaboration.  As director of this collaborative core effort, Dr. Brayton reaches out to JHU faculty investigators who wish to participate in multidisciplinary initiatives, and additional participants in the core network are always welcome.  Since 2006 we have organized symposia and courses that emphasize JHU resources and faculty, including JHU Phenotyping Symposia in 2006, 2007, 2008, 2009, SOM graduate school course (ME 680.712) in 2007, 2008, and annual Mouse Pathobiology and Phenotyping Short Courses since 2010, and phenotyping and comparative pathology slide conferences.  She has become involved in national and international phenotyping initiatives, conferences and courses to promote understanding of mouse biology, pathology and phenotyping in contemporary preclinical translational research.

Research

Dr. Brayton’s primary research interest is in collaborating on pathology and experimental design for many areas of preclinical translational science.  Whether caused primarily by spontaneous mutations or infections, by intended genetic manipulations or other experimental interventions, phenotypes and experimental results are impacted by unintended and often under recognized nature and nurture influences.  Dr. Brayton’s expertise includes the spontaneous pathology and genetics of research mice, as well as the impact of infectious and other environmental factors on pathology and other phenotypes.  She has published on comparative cardiovascular, pulmonary, renal, musculoskeletal, hematopoietic, neural and ophthalmic pathology, comparative carcinogenesis, autoimmune diseases and infectious diseases, in mice and other species. 

Contact me to discuss phenotyping, collaboration or research pathology needs.

Teaching

Dr. Brayton’s primary teaching interest is to improve and promote understanding of model organism biology and pathology, especially as it is relevant to phenotyping and experimental design for translational research.  She has developed, directed, co-directed, and lectured in symposia, conferences, courses and workshops relevant to phenotyping, pathology, genetics of mice and other laboratory animals, in the US and abroad.  She has authored and coauthored books, chapters and invited reviews on mouse biology and pathology. At JHU, she has developed symposia and courses including the Mouse Pathobiology and Phenotyping Short Course, and participates as faculty and lecturer in  680.701 Principles of Animal Pathology and Genetically Engineered Mice;  680.702 LAM/PATH Integrated Problem Solving; 690.707 Experimental Design and Scientific Writing; 680.711 Comparative Pathology Conference; Toxicological Pathology, Bloomberg School of Public Health, and other courses.
