About Dr. Raheleh Ahangari


Dr. Raheleh Ahangari is an Assistant Professor of Medicine (teaching position) in Burnett School of Biomedical Sciences at UCF College of Medicine and is teaching Human Physiology, Clinical Embryology and Clinical Endocrinology.

She received her Doctor of Medicine (M.D.) degree from Carol Davilla Medical University, Bucharest, Romania (1987- 1993) and took several graduate neuroscience courses in the department of Cell Biology and Pathology in the Faculty of Medicine in University of Salamanca to receive “Sufficient Investigator” status in her graduate studies (1997- 1999) where she carried out research in trigeminal neuralgia and headache under supervision of Dr. Rafael Covenas. She then moved to Germany for a post-doc position in Wuerzburg, Germany in 2000. Her studies focused on immunology, looking for signal transduction mechanisms in apoptosis and T-cell proliferation in department of immunology-virology (supervisor: Dr. U. Bommhardt) of Wuerzburg University (2000). She continued her post-doc studies on Macro-patch-clamp recording of the hemi-diaphragm, to characterize the receptors involved in neurotransmission including pre- and post- synaptic molecules involved in the pathogenesis of Guillain Barré syndrome (GBS) and Miller Fischer syndrome in 2001-2002 (Supervisors: Dr. B. Buchwald and Dr. C.V. Toyka, head of the neurology university hospital).

In 2003, she received an Assistant Professor position in Anatomy in Saba university school of medicine, Saba, Netherlands-Antilles, and moved to the United States in Aug. 2004. She joined UCF as a teaching faculty in fall 2005 and got involved in research in Dr. H. Daniell’s lab, looking for therapeutic effects of oral delivery of pro-insulin conjugated to cholera toxin-B subunit produced in tobacco and lettuce fed to diabetic mice (2005- 2006). Dr. Ahangari co-developed clinical embryology and congenital malformations as well as clinical endocrinology courses in UCF in 2006 and teaching them since then.

Dr. Ahangari is a graduate faculty scholar and has directed several independent studies in endocrine and metabolic disorders and was involved in a number of honors in major thesis works. Her research/scholarly activities are focused on trigeminal neuralgias and headache as well as inflammation. She is a Co-PI of a SBIR research with Dr. P. Mangos from Adaptive Immersion Technologies,  working on the development of a Holographic Health Avatar for Predictive and Preventative Medicine (2016-2017).
