  • Research Interest

    RESEARCH INTERESTS:

    One of the greatest discoveries in medicine is the potential use of stem cells to help the reducing suffering of numerous diseases, such as diabetes, cancer and neurodegenerative disease. My main research interests are using of stem cell technology for neurodegenerativedisease modeling and to identify the potential targets for disease therapy to improve the quality of human life. Currently, there are several research projects going on in my laboratory.

    Project 1: Human Pluripotent Stem Cell Neuronal Differentiation

    We have defined culture conditions for generating sub-type or region-specific neurons from human embryonic and induced pluripotent stem cells without genetic manipulation.Furthermore,we have established a stem cell neuronal differentiation protocol to derive cerebral organoids that contain neurons, astrocytes, and microglia. So far there are few reports using the cerebral organoids containing microglia. Using this cellular model to study the role of microglia in neurodegenerative diseases and identify potential cellular targets for Alzheimer鈥檚 disease and stroke therapy.

    Project 2: The Role of Microglia in Neurodegenerative Diseases

    Microglia are resident immune cells of the central nervous system. Microglia have diverse functions, ranging from controlling neurogenesis, pruning synapses, secreting trophic factors for remodeling extracellular matrix, and clearing aggregated proteins. Our studies show that chronic inflammation, induced by an unhealthy diet or neurotoxin can induce a neurotoxic phenotype M1 microglia activation. Neurotoxic microglia involve in several CNS neurodegenerative pathologies including Alzheimer鈥檚 disease and Parkinson鈥檚 disease. An alternative M2 state of microglia is primarily associated with promoting neurogenesis and extracellular composition reconstruction. The goal of my research is to understand the molecular mechanisms that govern the diverse phenotypes of microglia both in healthy and pathophysiological conditionsand target microglial phenotype switching for neurodegenerative disease treatment.

    Project 3: Stem Cell Neuronal DifferentiationCellular Model for Nanoparticles, Bisphenol A, and E-cigarettes Neurotoxicity Testing

    Nanotechnology (i.e., nanoparticles) has the potential to top the industrial revolution, but its impact on human mental health is poorly understood. Stem cell neuronal differentiation is an excellent platform for evaluating the neurotoxicity of nanoparticles. We are currently using this cellular model to evaluate the effects of nanoparticle as well as other environmental toxins such as Bisphenol A and nicotine on neuron-astrocyte-microglia networks and mental health.
