Kamitakahara, Anna

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.

Levitt, Pat

Provost Professor of Cell and Neurobiology, and Pharmacology and Pharmaceutical Sciences, and Psychology

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.

Liman, Emily

Harold W. Dornsife Chair in Neuroscience and Professor of Biological Sciences

The Liman lab studies how ion channels enable sensory cells to convert chemical and mechanical cues into electrical signals. We discovered the Otopetrin (OTOP) family of proton-selective ion channels and showed that OTOP1 is the long-sought sour-taste receptor as well as a detector of ammonium. Using patch-clamp electrophysiology, structure-guided mutagenesis, cryo-EM, and in vivo genetics we aim to reveal how protons permeate OTOP pores, how gating is tuned by pH and lipids, and how channel activity shapes taste, balance, and metabolic physiology. Ongoing projects extend these questions to other OTOP isoforms combining medium-throughput screening with computational modeling to identify first-in-class modulators and mouse genetics to identify and manipulate cells that express OTOP channels. Students gain rigorous cross-disciplinary training in membrane biophysics and sensory neuroscience while working in a collaborative, inclusive environment.

Matho, Katherine

Assistant Professor of Pediatrics

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.

Moore, Jeffrey

Assistant Professor of Biological Sciences

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.
