Assistant Professor of Research
Research in the Kamitakahara Laboratory investigates how genes and the environment shape the development and mature function of the neural circuits controlling feeding behavior. Specific topics examined include: 1) the impact of perinatal nutrition on gut-brain signaling of satiation and reward-based feeding behaviors, and 2) the genetic and biological contributions to inter-individual differences in response to GLP-1 receptor agonist treatment. Mechanistic understanding of neural activity and feeding behavior is probed using advanced techniques such as bulk and single cell RNA sequencing, highly multiplexed in situ hybridization, and metabolic cage phenotyping. Through delineation of the genes and dietary factors that shape feeding behavior, research in the Kamitakahara lab aims to provide insight into the biological mechanisms underlying overconsumption and cardiometabolic disease.

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.

Associate Professor of Psychology
Our lab is primarily focused on decision-making, especially in the context of addiction and obesity. We use self-report, behavior, and fMRI. Our lab is currently (through 2028) participating in USC’s Tobacco Center of Regulatory Science (supported by NIH & FDA).
