EMPLOYMENT/RESEARCH EXPERIENCE & SKILLS

2015-19 Lecturer in Medicine, Harvard Medical School and Director of Animal Research, Rheumatology and Clinical Immunology, Medicine, Beth Israel Deaconess Medical Center. Boston, MA

Studying the immune/inflammatory role of platelets in systemic lupus erythematosus (SLE) in the MRL.lpr and B6.lpr mice using platelet depletion.

- proficient in developing in vivo animal models (autoimmune diabetes, trauma, and SLE) and mouse models of platelet depletion/platelet transfusion.

- used histology, immunocytochemistry, immunofluorescence and confocal microscopy to identify platelets and platelet:leukocyte aggregates in kidneys of mice with disease.

- used multi-parameter flow cytometry to phenotype platelet:leukocyte aggregates, leukocyte subsets, and platelet activation in lupus mice.

- developed of a mouse tumor model to study Ewing sarcoma metastasis.

2007-11 Instructor in Medicine, Rheumatology and Clinical Immunology, Medicine, Beth Israel Deaconess Medical Center and Harvard Medical School, Boston, MA.

Developed a research program to study the role platelets in local and remote tissue damage using mouse models of platelet depletion/transfusion. Also trained and directed visiting scientists, research fellows and summer students. I wrote and was the principal investigator on the IACUC animal protocol.

- experience in platelet characterizing immune responses/inflammation in mouse models ischemia/reperfusion injury (I/R I).

- in vivo antibody titering and platelet depletion/platelet transfusion and lymphoid cell passive transfer, mouse surgery.

- identified differences in platelet responses after local trauma and the importance of signaling pathways in platelet activation in response local trauma; identified their role in remote lung damage after mesenteric I/R injury using histology and immunocytochemistry.

2003-07 Instructor in Surgery, Department of Surgery (Immunology), Brigham and Women’s Hospital and Harvard Medical School, Boston, MA.

Developed a research program to study the role of platelets in the immune response to inflammation. Trained, directed and assisted research fellows.

- experienced in platelet characterization in immune responses in animal models of burn injury.

- in vivo antibody titering for platelet depletion/transfusion and lymphoid cell passive transfer.

- identified differences in platelet responses after burn injury and the role of platelet CD40 and CD154 in platelet activation.

- identified a central role for platelets modulating the pro-inflammatory immune response in preventing mortality after burn injury.

- multi-parameter flow cytometry to phenotype leukocyte/lymphocyte subsets and cytokine production.

1998-99 Research Scientist, Biochemistry/Immunology [New Product Development], Research and Development, Coulter Cellular Therapies, Inc., Medford, MA.

Designed and developed a novel human T lymphocyte expansion platform using proprietary materials for personalized cancer treatment.

1994-98 Post-Doctoral Fellow, Division of Surgical Research and Division of Renal Medicine, University of Massachusetts Medical Center, Worcester, MA.

Studied apoptosis in trauma patient human lymphoid cells and identified potential immunotherapies to prevent diabetes in NOD mice.

EDUCATION
