We are a highly motivated group of scientists doing translational neuropharmacology research. Our lab is interested in receptor neuropharmacology and synaptic signaling of neurotransmitters and hormones under normal and disease conditions. We implement a variety of approaches including genetic, cell biological, biochemical, single-cell transcriptomic, proteomic, pharmacological and behavioral approaches. We utilize mouse models, human postmortem tissues and human iPSC-derived brain cells. Our ultimate goal is to discover cures for neuropsychiatric disorders.
Some of our focus are:
1. Molecular and cellular mechanisms underlying Alzheimer’s disease (AD) pathogenesis
a) noradrenergic dysfunction and adrenergic signaling in AD;
b) regulation of endosomal trafficking and its involvement in AD pathogenesis;
c) astrocyte reactivity in AD;
d) tumors and related therapies as risk factors for AD.
2. Cognition and complex behaviors
a) synaptic signaling in autism;
b) epigenetic regulation of anxiety and
c) a novel mouse model for ADHD.
3. Selective targeting of GPCRs
a) neural-specific enhancement of adenosine receptor for neuroprotection;
b) signaling-specific targeting of adrenergic receptor for AD.

Multiple NIH-funded postdoctoral positions are available for motivated and creative postdoctoral fellows to study disease mechanisms at molecular, cellular and system levels and to identify novel therapeutic strategies for neurological disorders. Excellent research techniques in biochemistry and molecular biology are preferred. Prior experience with brain research and skills in computation are valued. Candidates with biochemistry, cell biology and/or neurobiology backgrounds are encouraged to apply. The laboratory focuses on translational research in synaptic signaling and neuropharmacology. The postdoctoral fellow will have opportunities to conduct the innovative research projects with state-of-the-art technologies and model systems, such as CRISPR gene editing, single-cell RNA-Seq, super-resolution imaging, AI-aided design and analysis, patient-derived iPSCs and humanized mouse models. The fellow will be given opportunities to apply for training grants and encouraged to pursue independent research career, with a strong support from the mentor.
We seek postdoctoral fellows interested in studying Alzheimer’s disease. The candidates will hold a PhD or MD or equivalent in neuroscience, physiology, molecular/cell biology, biochemistry or neuropharmacology. Expertise in molecular biology and biochemistry is desirable. Candidates are expected to have good communication skills and have a strong drive for building a successful research career.
We welcome graduate students and are interested in potential rotation students. Prospective students can apply to our lab through the Graduate Program in Neuroscience as well as through the MD/PhD Program.
Undergraduate Students and medical students:
We accept motivated undergraduate students and medical students who are interested in biomedical research.
