Principle Investigator:
Carlos A. Pardo-Villamizar, MD
Dr. Pardo is an Assistant Professor of Neurology and Pathology (Neuropathology) at the Johns Hopkins University School of Medicine. His main focus of research is on immunological and molecular mechanisms of neurological disorders. Dr. Pardo's current projects center on studies of neuroimmunopathological mechanisms associated with HIV infection (e.g. HIV dementia and HIV neuropathy), multiple sclerosis, transverse myelitis, epilepsy and autism. Dr. Pardo is the principal investigator of a project that studies the role of neuroglia dysfunction in HIV infection and drug abuse (funded by NIH-NIDA K08-DA16160) and and co-investigator in several other NIH funded grants that focus on neurological complications of HIV infection. Dr. Pardo also receives funding from Cure Autism Now (CAN) Foundation to study neuroimmune mechanisms involved in pathogenesis of autism and has received previous support from the Epilepsy Foundation of America, Passano Physician Scientist and Johns Hopkins Clinical Scientist Awards.

Post-doctoral Fellows:
Diana L. Vargas, MD
Dr. Vargas is a physician graduated from the Universidad Javeriana School of Medicine in Bogota, Colombia. Dr. Vargas focuses her research on neuropathology and immunopathology of autism and HIV dementia. Her work has included analysis of cytokine and chemokines expression and neuroglial dysfunction in the pathogenesis of such disorders.

Caterina Nascimbene, MD
Dr. Nascimbene is a neurology resident from the University of Milan, Italy. She joined the lab in 2003 to work on projects related to HIV neuropathy and neuropathological assessment of the peripheral nervous system in the Simian Immunodeficiency Virus (SIV) infection model.

Senior technician
Liping Guo, BSc, MD
Ms. Guo is our Senior Technician and manager of the neurohistology lab. She graduated from the Medical University of Nanjing in China and has expertise in immunocytochemistry, morphological and molecular biological techniques.

Statistical support
James R. Williams (Graduate Student)
Mr. Williams is a Psychiatric Epidemiology doctoral student at the Johns Hopkins Bloomberg School of Public Health. He provides statistical support for the Neuroimmunopathology laboratory. Mr. Williams is broadly interested in psychiatric aspects of neurological disorders. He has been awarded two Parkinson's Disease Foundation summer fellowships for his work on non-motor aspects of Parkinson's Disease.

Adrea Lee
Ms. Lee is an undergraduate student in the School of Arts and Sciences of Johns Hopkins University. Ms. Lee is a Woodrow Wilson Fellow and has received a Provost Award for her undergraduate research.

Carolina Zerrate
Ms. Zerrante is a medical intern from the Universidad Javeriana School of Medicine in Bogota, Colombia. She will join the lab as postodoctoral fellow in January of 2005. Ms. Zerrante's main research activity focuses on autism and assessment of animal models for autism.
