Areas of Expertise
My laboratory is interested in understanding mechanisms of neuronal connectivity and plasticity, how these processes are modulated by environmental and genetic factors, and how they are altered in human diseases and under drug conditions. We employ a combination of behavioral, physiological, pharmacological, and genomic approaches for the following projects.
- Discovering fast-acting antidepressants. Depression is a prevalent, heterogeneous mood disorder, affecting ~16% of population worldwide. Currently available antidepressants have significant therapeutic limitations, highlighting the critical need for more efficacious therapies. Although ketamine represents a prospective new line of antidepressants with unique clinical advantages, its use as a long-term treatment has evident limitations, particularly its psychotomimetic effects and abuse potential. Advancements in our understanding of brain mechanisms involved in ketamine antidepressant actions are crucial to identification of novel therapeutic targets that could lead to development of a new generation of fast-acting antidepressants with minimal or no adverse effects.
- Beneficial effects of exercise on mental health. Growing evidence suggests voluntary exercise activates neurogenesis, neuroadaptive, and neuroprotective processes, together leading to beneficial effects on human. Insufficient physical activity associated with a sedentary lifestyle, on the other hand, is a major contributing factor to increased chronic disease risk. Our long-term goal is to understand how exercise affects the central nervous system and ultimately harness the positive influence of exercise on physical and mental health.
- Gut microbiota in mood regulation. Emerging evidence supports a bidirectional communication axis between the brain, the gastrointestinal tract, and the microbiota colonizing the gut (commonly referred to as the “brain-gut-microbiota axis”). Using shotgun sequencing and metagenomic analysis, we investigate the role played by the gut microbiome in mood (dys) regulation resulted from chronic stress or the affective component of chronic pain. Results on how gut microbiome help regulate the host stress response may shed light on potential targeted therapies at the microbiome for disease conditions.
