I have 30 years of experience as a researcher in the field of radiation biology and over 10 years as a clinical laboratory science with extensive experience in the field of hematology. During my career I have investigated the innate and adaptive immune responses of multiple animal models during the acute radiation syndrome with emphasis on hematopoietic and gastrointestinal syndromes. I also have also managed the large animal hematology laboratory, extramural contracts and performed research focused on the use of hematopoietic growth factors to mitigate radiation injury.
Currently, at University of Maryland, Baltimore I serve as Co-PI in the development and use of nonhuman primate models of the acute and delayed radiation syndromes in the hematopoietic, gastrointestinal and lung systems. I was charged with the implementation of Good Laboratory Practices at UMB and have been Study Director on three GLP-compliant studies. I served as the Study Director of a GLP-compliant study that resulted in an FDA study audit, a joint FDA Advisory Committee Meeting and approval by the FDA of the first-ever drug, Neupogen® approved for use in the event of a nuclear disaster. I served as Co-investigator in a second GLP-compliant study that contributed to the FDA approval of Neulasta® as a medical countermeasure for high dose radiation exposure.
I have been an invited speaker to national and international audiences on animal model development and the efficacy of hematopoietic growth factors to treat myelosuppresion and myeloablation. I have served as an administered hoc reviewer for Experimental Hematology, Haematologica, Bone Marrow Transplantation, International Journal of Radiation Biology, Journal of Controlled Release, European Journal of Haematology, Molecular Therapy, Biosimilars, BioMed Research International and Comparative Medicine. In summary, I have demonstrated a consistent and substantial record of accomplishment as an investigator, laboratory manager, scientific author and speaker in the field of radiation research.

C1. Elucidating the effects of radiation exposure either alone or in combination with another agent such as thermal injury or sepsis on survival and particularly the hematopoietic response in animal models. With the discovery, purification and manufacturing of hematopoietic growth factors, these models became invaluable in the early studies demonstrating the efficacy of recombinant hematopoietic growth factors to rescue severely myelosuppressed animals. These studies performed in our laboratory contributed to the database for Investigational New Drug applications to the FDA by several biotechnology companies such as Amgen, Inc., Immunex, Corp., Sandoz and Monsanto.

C2. Development of well characterized animal models to test the efficacy of potential medical countermeasures to treat humans in the event of high dose radiation exposure. Following the events of September 11, 2001, and the creation of the FDA “Animal Rule” our laboratory developed well-codified nonhuman primate modelsof the acute radiation syndrome (ARS) and delayed effects of acute radiation exposure (DEARE).
