The focus of Dr. Lim’s research is on neural stem cells and neurogenesis. He is particularly interested in the molecular biology of the population of neural stem cells found in the subventricular zone. Recently, Dr. Lim’s work has revealed that the chromatin remodeling factor called Mixed Lineage Leukemia-1 (MLL1) is essential for postnatal neural stem cells to make new neurons. Currently, his work focuses on the molecular mechanisms by which MLL1 specifies a transcriptional program instructive for neurogenesis. In the future he hopes to define the genetic programs and molecular mechanisms that guide the formation of neurons and glia from SVZ neural stem cells, and translate these discoveries into cell-based and genetic therapies for human neurological diseases.
In addition to his basic science interests, Lim has a clinical interest in stereotactic neurosurgery and has worked with Paul Larson MD and Phillip Starr MD, PhD to study deep brain stimulation for movement disorders including Parkinson’s disease, essential tremor, and atypical tremors resulting from multiple sclerosis or stroke.
