Research Interests
My long-term research goal is guided by a molecular-to-in-vivo perspective and driven by two major areas of investigation: first, to obtain a mechanistic understanding of how synaptic transmission and plasticity work and contribute to information processing by neural circuits, and ultimately how synaptic transmission and plasticity occurring within specified neural circuits give rise to complex behaviors; second, to obtain a molecular-based understanding of how circuit, cellular and channel/synapto-pathies might be the subject for therapeutic intervention, with a focus on motivational behaviors and animal models of neuropsychiatric disorders.
Towards this goal, I use synergistic state-of-the-art methodologies such as in vitro and in vivo electrophysiology, intersectional genetic approaches together with cell biology and molecular pharmacology.
