Eric Szelenyi, PhD.
Research group: NeuroPuentes: Neuroevolutionary Systems Biology Group
Research Areas: Deconstruction of distributed neural circuits and their function in health and disease / Discovery and characterization of biodiversity-derived neurochemical systems from plants and animals / Neuroimmune mechanisms underlying anxiety, depression, and neurodegenerative disorders / Computational approaches to behavioral and neural circuit phenotyping, and molecular modeling / Molecular genetic tool development for high-throughput neural circuit discovery and brain receptor target engagement
Current research:
NeuroPuentes investigates biodiversity-derived neurochemical systems and their capacity to influence neural circuits and neuroimmune function in the mammalian brain. The program integrates molecular discovery from plant and animal sources with quantitative circuit analysis and computational modeling to connect molecular interactions to large-scale brain dynamics.
By treating naturally occurring neuroactive repertoires as structured biological probes, the group seeks to understand how coordinated molecular perturbations reshape neural and neuroimmune states, revealing fundamental principles of brain regulation and dysfunction.
