    • Research Description

    My students and I are interested in central neural circuits and synapses. We enjoy developing new experimental approaches that combine cutting-edge techniques, including recombinant DNA delivery and replacement, multiple whole-cell recordings, two photon laser scanning and immunoelectron microscopy. These approaches provide new windows to view subcellular or nanoscale biological affairs (e.g., Ras/MAPK signaling-regulated AMPA-R trafficking and circuit organization). Because genetic defects of molecules involved in Ras/MAPK signaling may lead to a number of cognitive disorders (e.g., Akt/PKB and calcineurin with schizophrenia, BRaf with cardio-facio-cutaneous syndrome, CaMKII with Angelman syndrome, H-Ras with Costello syndrome, p38 MAPK and JNK with Alzheimer's disease, PI3K with fragile X syndrome, PTEN with autism, Cowden and Bannayan-Riley-Ruvalcaba syndromes, RasGap NF1 with neurofibromatosis, Rsk with Coffin-Lowry syndrome and X-linked mental retardation, SHP-2 with Noonan syndrome, and tuberin with tuberous sclerosis), the findings from our research should guide the future development of treatments for these insidious diseases.
