Background, Training and Current Position

Before she entered Veterinary school, she worked in neuroscience and endocrinology research at the University of Texas, San Antonia, University of California, San Diego and the San Diego Zoo. This experience undoubtedly led her back to pursue research after her veterinary medicine training. She graduated from North Carolina State University Veterinary College of Medicine in 1989 and next entered a postdoctoral fellowship in veterinary pathology at Johns Hopkins University School of Medicine. Before entering a PhD program in toxicology at the Johns Hopkins University School of Public Health, she worked as a diagnostic pathologist and became board certified by the American College of Veterinary Pathologists.  Her PhD project bought here back to the field of neuroscience, as she studied the mechanisms of toxicity behind the mitochondrial toxin 3-nitropropionic acid (3NPA).  During this investigation, she discovered that 3NPA was not only a neurotoxin, but also a cardiac toxin. This finding remodeled her research focus to the study of cardiac toxicity and cardiac diseases. She joined the faculty of Comparative Medicine in 2000 and through this appointment, she is involved in the teaching and training of post-doctoral fellows in laboratory animal medicine and veterinary pathology.  She also have an appointment in Environmental Health Sciences in the Johns Hopkins University School of School of Public Health, and through this appointment, developed and directs a graduate course in Toxicological Pathology, as well as co-direct a core facility for molecular imaging and pathology, sponsored by a NIEHS center grant.  She also has a faculty appointment in the Center for Alternatives to Animal Testing and through this position participated in the web-based course “Enhancing Humane Science/Improving Animal Research”.

Research Focus

Her research efforts focus on the signal transduction of cardiovascular toxicities in vitro, in cardiomyocyte culture and in vivo, using rodent models.  Specifically, the research focuses on the understanding the mechanisms of various cancer therapies that induce cardiac toxicities.  Currently she is testing prevention strategies for these toxicities.  She is studying the cardiac effects of the anthracycline doxorubicin (adriamycin) and the immunotherapeutic agent, Herceptin, anti-erbB2.  For patients concurrently treated with Herceptin and doxorubicin, the risk of cardiac dysfunction is 28% compared to 7% in doxorubicin alone treatment.  She is focusing on the signal transduction pathways in the heart that are modulated by anti-erbB2 treatment, which in turn, worsens doxorubicin toxicity. Thus, understanding the mechanisms behind the combined toxicity of doxorubicin and anti-erbB2 will pave the way for the design of strategies to reduce toxicity, identify patients at risk and potentially allow higher levels of this effective combination therapy to be used with an improved long-term survival in patients.  In another doxorubicin animal model, she is using the neu mouse model that overexpresses neu (erbB2) and thus develops breast cancer, to test several strategies to prevent doxorubicin toxicity.  For evaluating various cardiac protection strategies, in conjunction with molecular studies, she is also using histopathology, clinical pathology and non-invasive echocardiography in both acute and chronic models of doxorubicin toxicity.  Tumor growth and regression is also being monitored during treatment.  Some of the pharmacological strategies she is testing have also been show to reduce tumor burden.  To complement the in vivo studies, toxicity assessments and pharmacological strategies are first screened in vitro in neonatal and adult rat cardiomyocyte cell culture.  These projects are funded by a Scientist Development Grant award from the National American Heart Association program, Department of Defense- Breast Cancer Research program and from pilot project funds from the Breast Cancer SPORE and the American Cancer Society.

She is also currently collaborating with multiple investigators within JHU and other universities ranging from cancer research to cardiovascular research

Students and Post-doctoral Fellows
She has assisted in the mentoring of 7 undergraduate pre-vet and pre-med students, 5 veterinary students, 2 pre-doctoral students and 12 post-doctoral DVM fellows in Comparative Medicine since 2000.
