Charles Chavkin, PhD | NAPE Center Director | Professor | Pharmacology | Anesthesiology and Pain Medicine

The Chavkin lab focuses on understanding the molecular signaling of mu and kappa opioid receptors. They use a combination of molecular pharmacological, biophysical, anatomical, genetic and behavioral techniques to study the properties of the opioid systems in mouse brain. Current studies in the Chavkin lab are designed to further characterize how specific neural circuits controlling stress-induced potentiation of drug reward are regulated by the dynorphin/kappa receptor systems and how different kappa receptor agonists and antagonists display distinct functional selectivity.

We use strategies that span several levels of organization from RNA regulation, protein translation, cellular plasticity, and neural circuit level analysis of complex behaviors relating to stress and addiction models. We use rat and mouse behavioral models as well as in vitro cultures of cell lines and primary neurons to study components of intracellular signaling pathways.

Richard Palmiter, PhD | Professor | HHMI | Biochemistry

The Palmiter lab is interested in the neural circuits that control innate behaviors such as eating and drinking. Palmiter and his team use mouse genetic models and viral gene transfer to study neural circuits in specific brain regions. Their goals are to visualize where relevant neurons are located and where they project their axons, to record the neurons’ activity in real time, and to evaluate the behavioral and physiological consequences of activating or inhibiting those neurons. They also aim to identify downstream targets of certain neurons and discern how they are involved in responding to various threats, including pain, itch, and food poisoning.

Paul Phillips, PhD | Professor | Psychiatry and Behavioral Sciences | Pharmacology

Work in the Phillips lab investigates the role of dopamine transmission in normal and pathological mental function (including drug abuse) utilizing multi-disciplinary approaches. The lab uses traditional behavioral paradigms such as operant behavior and classical conditioning as well neuroeconomic approaches to study decision making. During these studies, dopamine neurotransmission is monitored directly using real-time electrochemistry to identify components of dopamine transmission that are altered during behavior or pathology, and computational models are applied to these data.

Garret Stuber, PhD | Professor | Anesthesiology and Pain Medicine | Pharmacology

The major goal of the Stuber lab is to delineate the neural circuits involved in the manifestation of neuropsychiatric disorders including addiction, maladaptive eating behaviors, and anxiety. To accomplish this, the Stuber lab take a multidisciplinary approach, relying on innovative techniques to selectively perturb and monitor neural activity in genetically specified populations of mammalian neurons.

They aim to detect impaired neuronal function which will provide key knowledge about the underlying causes of neurological disorders such as autism, schizophrenia and depression. Research interests include structure-guided and automated high throughput protein engineering, optogenetics, and neuronal circuit dynamics in mammalian disease models.

Ajay Dhaka, PhD | Associate Professor | Biological Structure

The Dhaka lab is interested in understanding the mechanism by which sensory information is coded by the peripheral nervous system, and how specific subclass specificity and neuronal circuit assembly occurs during development. In addition, we are working to identify novel sensory receptors for modalities such as mechanosensation, temperature and nociception. These are fundamental neurobiology themes that are relevant to the study of the many forms of chronic pain, which are debilitating to millions of individuals.

The Schindler lab is interested in in traumatic stress and its comorbidities (e.g. affective disorders, substance abuse, metabolic dys-function, neurodegeneration). Using an iterative translation approach, they utilize both human and animal populations and focus on reciprocal connections between the brain and peripheral organs (e.g. liver, gut, lymph) in order to under-stand adverse outcomes of traumatic stress from a systems biology standpoint. Schindler and her team are especially interested in under-standing the role of monoamines (e.g. dopamine, seroto-nin) and neuromodulators (e.g. opioids, cytokines). They uti-lize computational medicine approaches (e.g. machine learning, big data, electronic health records, biomarkers) and are committed to open source science.

Carlos Campos, PhD | Assistant Professor | Division of Metabolism, Endocrinology, and Nutrition

The Campos lab examines how physiological signals related to internal state interact with other sensory systems to affect learning and memory, the neurological underpinnings of prediction. We study both sensory systems that convey the status of the body to the brain, that innervate internal organs to sense things such as hunger, illness, arousal, as well as those that sense the external world and the quality of the objects within it – for example the feeling of pain or the tastiness of food that motivates approach or avoidance. In studying these systems and the places in the brain where they interact, we hope to discover how we learn to predict changes to our physiology based on associations with our external world.
