Education:

B.S.   Davidson College, - 1980
Ph.D.   Emory University School of Medicine Department of Microbiology and Immunology; Thesis Advisor: Dr. Linda L. Perry, - 1985
M.D.   Emory University School of Medicine, - 1986

Research Interests:

- Mucosal Immunology; Chemokine Receptors; Lymphoid Organogenesis The major areas my laboratory studies are: (1) the role of chemokines and chemokine receptors including CCR6, CCR9, and CCR10 in mucosal immunity; and (2) the cellular interactions, cytokines, and chemokines involved in initiating the development of the lymphoid aggregates present in the small intestine including cryptopatches and isolated lymphoid follicles.

Clinical Focus:

The Clinical Immunology Laboratory at Emory University Hospital performs a variety of immunology tests including protein electrophoresis and immunofixation, immunoglobulin and serum protein quantitation by nephelometry, cryoglobulin testing, miscellaneous protein testing, autoantibody detection, infectious disease serology testing, and measurement of a variety of analytes on automated immunoassay platforms. The laboratory also plays a major role in serological testing of samples from tissue and organ donors. A medical technician from the laboratory is on call at all times to perform stat infectious disease serology testing on samples from organ donors prior to transplantation. The immunology laboratory also supports specific types of surgery that require intraoperative immunoassays down with a short turn around time (most commonly this is testing for parathyroid hormone or PTH in patients with hyperparathyroidism).

In addition to my administrative role in the laboratory, I also do the physician interpretations of protein electrophoresis and immunofixation testing. Interpretation of protein electrophoresis and immunofixation tests as well as some autoantibody testing (primarily anti-neutrophil cytoplasmic antibody or ANCA testing) is done with the assistance of CP residents who rotate for one month on the clinical immunology service. Drs. Charlie Hill and Alexis Carter also take turns signing out these cases that need physician interpretations. Serum protein electrophoresis and immunofixation are performed to detect the presence of monoclonal immunoglobulin species (also known as paraproteins) in patients with plasma cell dyscrasias including multiple myeloma, amyloidosis, and monoclonal gammopathy of undetermined significance. Other diseases associated with paraproteins are Waldenstroms macroglobulinemia and some types of B cell lymphoma. Patients with monoclonal gammopathies are monitored during their therapy using the paraprotein levels as an index of residual tumor burden. CSF protein electrophoresis is used to detect oligoclonal IgG bands associated with multiple sclerosis and other immunologically-mediated demyelinating diseases. The Emory immunology laboratory has recently introduced a more sensitive isoelectric focusing method for the detection of oligoclonal IgG bands.
