Research Interests

Chronic stress, neurodegeneration, depression, synaptic plasticity, behavior

Research in our lab is focused on understanding molecular, cellular and epigenetic mechanisms underlying the pathogenesis of neurodegenerative and neuropsychiatric disorders. Our on-going projects include 1) cellular mechanisms underlying chronic stress-accelerated brain aging and neurodegeneration; 2) histone modifications during aging and in Alzheimer’s disease (AD); 3) adipokine modulation of synaptic plasticity and cognitive behaviors; 4) role of inflammaging progression in neurodegeneration; and 5) hippocampal and hypothalamic neurons in stress response and adaptation.

Open Positions in the Lab

We are currently welcoming postdoctoral fellows, graduate students and undergraduate students to join our laboratory.

Postdoctoral Fellows

We seek postdoctoral fellows interested in studying Alzheimer’s disease, inflammaging, stress neurobiology, and depression. Candidates are expected to have good communication skills and have a strong drive for building a successful research career.

»Æ¹Ï¶ÌÊÓƵ Students 

We welcome graduate students and are interested in potential rotation students. Prospective students can apply to our lab through the »Æ¹Ï¶ÌÊÓƵ Program in Neuroscience as well as through the MD/PhD Program.

Undergraduate Students 

We accept motivated undergraduate students who are interested in biomedical research.
