Currently I work as Senior Research Coordinator facilitating several clinical research projects at Baylor College of Medicine (BCM) and Texas Children's Hospital (TCH) involving the development of new treatments for children affected by disorders of neurological development.   

As section webmaintainer, I create and manage sites for BCM Pediatric Neurology and Developmental Neuroscience, the Gordon and Mary Cain Pediatric Neurology Research Foundation Laboratories, TCH intranet sites for the Neurology Department and the Blue Bird Circle Clinic for Pediatric Neurology, a NIH Post-Doctoral Training Program website, and public TCH webpages for affiliated neurology clinics and faculty.

Working in Dr. Gary Clark's lab in the Cain Foundation Laboratories,  I participated in basic science research investigating neuronal migration disorders of human brain development.  Research focused upon the Lis1, Reelin, Dab1, and DCX genetic pathways and the cytoskeletal basis of neuronal migration. Mutations of these genes cause impairments of neuronal migration, positioning and connectivity that often produce seizures, epilepsy and premature death in affected individuals.  

The images, videos and presentations shown below are representative of my work from the lab involving cell culture, transfection, staining, microscopic imaging, image processing and web preparation, and are presented for educational  purposes to stimulate interest in neuroscience research.
