Academic Title: Associate Professor
Primary Appointment: Pediatrics

Location: Bressler Research Building 13-017
Phone: (410) 706-8135

Research Interests:

My research is focused in elucidating how different types of external insults (such as early alcohol exposure) disrupt activity-dependent plasticity and how we can restore it.


Lab Techniques and Equipment:

To devise new ways to improve plasticity in models of neuro-developmental disorders my lab uses in vivo viral-mediated gene transfer and pharmacological manipulations. The effects of these types of interventions are measured at different levels: a) Molecular- Imunohistochemistry and Imunoblotting; b) Cellular: Single-Unit electrophysiology, Staining with Neuronal tracers c) Systemic: Optical imaging of intrinsic signals; Visual evoked potentials d) Behavioral: Morris water maze, Social play behavior analysis.
