Our group is dedicated to translational research and training. Our laboratory focuses on human induced pluripotent stem cell (hiPSC) technologies to model infections with viruses that are common and can impair cognitive functions, including Herpes simplex virus, type 1 (HSV-1), Cytomegalovirus (CMV) and Zika virus (ZIKV). Our group was the first to develop iPSC-based models of latent HSV-1 infection. Our cellular models have enabled us to identify several novel compounds that potently inhibit HSV-1 and ZIKV infections. Our prime candidate is R430 (trans-dihydrolycoricidine), a lycorane-type alkaloid derivative that has potent, broad-spectrum antiviral effects. We are now synthesizing and testing new derivatives to identify active pharmacophores. Separately, we have used our hiPSC-neuronal models to investigate copy number variants (CNVs) that elevate risk for psychiatric disorders. We are presently refining three-dimensional culture models of hiPSC-derived neurons for our work.
The translational arm of our work emphasizes research-based training, with a bias towards low and middle-income countries. We have helped to establish independent, fully functional laboratories and clinical research groups in India and Egypt. Our training programs are firmly grounded in empirical research and are complemented by didactic coursework. We encourage trainees to nurture their research ideas, drawing on resources available through our ongoing research. Our work has been continuously supported for the past 25 years by the National Institutes of Health and currently focuses on novel interventions for severe psychiatric illnesses.
