The prevalence of obesity has exploded over the past 40 years. The biological systems that underlie the excessive eating behavior contributing to obesity onset remain poorly understood. Our research goal is to discover the neural systems and psychological processes that control energy balance, with a particular focus on understanding the neurobiological substrates that regulate obesity-promoting behaviors such as food impulsivity and environmental cue-induced feeding. Another primary focus of our lab is to study how the brain is negatively impacted by dietary and metabolic factors. Consumption of Western diets (high in saturated fatty acids and sugars) not only contributes to obesity development, but also produces deficits in learning and memory capabilities and can even increase the risk for developing dementia. We are currently examining the specific causal dietary factors, critical developmental periods, and neurobiological mechanisms underlying diet-induced cognitive decline. Ongoing research identifies the gut microbiome as a critical link between unhealthy junk food diets and neurocognition.

The focus of my laboratory is to explore the underlying mechanisms and potential of neuromodulation for cognitive dysfunction and psychiatric disorders, such as Alzheimer’s disease, Parkinson’s disease, epilepsy, depression, obsessive compulsive disorder and schizophrenia. Specifically, we utilize multiple depth electrode local field potential recordings and functional ultrasound imaging to evaluate simultaneous electrophysiology, cerebral blood flow and functional connectivity in these disorders. Using these tools, our goal is to better understand the underlying pathophysiology and optimize our neuromodulation strategies. Our aim is to translate our preclinical findings into clinically relevant neuromodulation treatments. My clinical research is focused on evaluating potential new indications and targets for neuromodulation, such as deep brain stimulation (DBS), spinal cord stimulation and focused ultrasound.

The research projects are driven by a talented group of postdoctoral fellows, graduate students, research staff and collaborating faculty. Our laboratory is unique in undertaking both basic and clinical research projects. Research projects investigate the development of brain architecture underlying emotional and social behavior and learning, the challenges that arise when neurodevelopment is derailed, and determining why brain and certain medical disorders often co-occur in children. The basic science projects are focused how genes and prenatal and early postnatal environments together influence typical and atypical development. The clinical research projects focus on understanding the impact of early experiences, positive (social connectedness) and negative (early life adversities - neglect/abuse) on healthy brain and child development and the impact on metabolic health.

The overall mission of the laboratory is to enhance neural plasticity in a wide population of individuals in order to improve their quality of life and engagement in meaningful activities. We particularly focus on individuals with stroke using big data neuroimaging approaches, along with noninvasive brain stimulation and brain computer interfaces.

How do developmental and genetic programs build brain circuits for complex behavior? My lab investigates this question by integrating developmental neuroscience, molecular genetics, and multi-scale circuit mapping to study cortical sensorimotor circuits underlying goal-directed actions and perception. Using interdisciplinary approaches, such as gene knockin mouse lines and single cell profiling, we examine how neuronal identity and connectivity emerge during development. Our goal is to uncover the molecular and developmental logic of circuit assembly in neurotypical development and how the key building blocks that make up the circuits—cell types—are disrupted in neurodevelopmental disorders. We hypothesize that a temporal patterning program during pregnancy specifies neuron subtype and wiring, shaping sensorimotor function in the mature brain.
