RESEARCH

My laboratory is interested in understanding the complex interactions between the immune system and the brain, with an emphasis on inflammation-induced neuropsychiatric and neurodevelopmental diseases. We have identified the kynurenine pathway of tryptophan metabolism as an important mediator of the effects of proinflammatory factors in the brain. Currently projects in the lab are exploring the (1) effects of neurotoxic kynurenine metabolites on depressive behaviors and cognitive function (2) the neurodevelopmental consequences of targeted deletion of the kynurenine metabolizing enzyme KMO (3) and the role of brain-derived neurotrophic factor in regulating neuroinflammation.
