Physiology of the Inner Ear Laboratory focuses on understanding the physical and physiological mechanisms underlying sensory transduction in the inner ear, with the ultimate goal of understanding how disease and injury impair function. The lab. studies sensory transduction in the auditory and vestibular systems both at the cellular and system level using electrophysiology and biophysical modeling. Our work relies heavily on the interplay between quantitative analysis, theoretical modeling and experimental neuroscience.

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.

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.

Many mammals sense and affect their environment predominantly through innate motor programs for exploration, social interaction, and ingestion; yet, little is known about the neuronal circuits that control these motor programs. Our lab uses molecular, systems, and computational neurobiological techniques to identify specific brainstem motor control modules and to determine how higher-order brain structures engage these modules for innate behaviors.
