Title of talk:  The Wiring Diagram for Hunger and Satiety:  Using Cell-Specific Cre/Lox Tools to Discover its Neural Basis

Bradford B. Lowell, MD, PhD 
Professor of Medicine, Harvard Medical School, Beth Israel Deaconess Medical Center

Research interests: Neurobiological and neurocircuit basis for leptin action and melanocortin-4 receptor action, role of synaptic transmission and NMDAR-mediated synaptic plasticity within feeding circuits, afferent inputs regulating AgRP and POMC neurons, efferent circuits responsible for effects of AgRP and POMC neurons on feeding behavior, dissection of neural pathways regulating sympathetic outflow and energy expenditure, and neural mechanisms by which the brain controls glucose homeostasis.

Title of talk:  An integrated view of the role of brain insulin signaling in nutrient partitioning

 

Christoph Buettner, PhD
Associate Professor, Medicine, Endocrinology, Diabetes and Bone Disease; Associate Professor Neuroscience, Mount Sinai Hospital

Research interests: To understand how hormones and nutrients are sensed by the hypothalamus and how the brain controls systemic metabolism.  Hormones like insulin and leptin regulate systemic inflammation via the brain and the autonomic nervous system.  We speculate that this may be the basis for the link between impaired metabolic control and inflammation.

Title of talk:  Diabetes, Bariatric Surgery and the Gut

Tony K.T. Lam, PhD
J.K.McIvor (1915-1942) Endowed Chair in Diabetes Research; Canada Research Chair in Obesity; Associate Professor, Departments of Physiology and Medicine, University of Toronto; Associate Director, University of Toronto Banting and Best Diabetes Centre; Senior Scientist, Toronto General Hospital Research Institute


Research interests:  The long-term goal of my lab is to unveil novel molecules/pathways in the body that regulate both hepatic glucose production and food intake in vivo, and consequently reveal new therapeutic molecules that could be targeted to restore glucose and energy homeostasis in diabetes and obesity.

Title of talk:  Why does gastric bypass surgery work?

Hans-Rudolf Berthoud, PhD
George H. Bray Professor, Neurobiology of Nutrition Laboratory, Pennington Biomedical Research Center, Louisiana State University
Research interests: The role of the nervous system in the processes maintaining energy homeostasis and nutrient intake.  This includes the receptors and pathways that allow the peripheral nervous system and the brain to sense the internal metabolic state and availability of important nutrients as well as external food environment, the neural circuits integrating this information, and the behavioral, autonomic, and endocrine effector pathways leading to regulatory actons.  Interests include anorexia, gastrointestinal and liver physiology, gut-brain interactions, autonomic nervous system, cognitive neurosciences, taste physiology, and functional foods.

Title of talk:  Peripheral and Central actions of the metabolic regulator FGF21

Eleftheria Maratos-Flier, MD
Professor of Medicine, Endocrine Division, Beth  Israel Deaconess Medical Center

Research interests:  The role of CNS in regulating feeding behavior and energy homeostasis with particular focus on hypothalamic-striatal pathways and the role of hormone lepting and the neuropeptide MCH in modulating motivated behavior.  My lab initially discovered the orexigenic role of MCH using RT-PCR differential display and we have since followed up on its role by generating over-expressing and knockout mice.  We also use mice lacking MCH as a model of anorexia.

Title of talk:  Is long-term weight loss possible?

James O. Hill, PhD
Executive Director, anschutz Health and Wellness Center, Anschutz Professor of Health and Wellness, Professor of Pediatrics, Medicine, and Physiology & Biophysics, University of Colorado, Anschutz Medical Campus

 

Research interests: Dr. James Hill is one of America's foremost experts in weight management, researching causes of weight gain, adiposity and obesity.  Research includes translating the science of weight management into public health programs like "The Colorado Weigh" and "America on the Move," that promote simple changes in lifestyle that dramatically change body weight and work in the community.

Title of talk:  The Neurobiology of Need 

Scott M. Sternson, PhD
HHMI Scientist, Janelia Farm Research Campus

Research interests: Reverse engineering the mouse brain in order to understand how neural circuits control innate behaviors.  He combines synthetic chemistry with genetics to deliver molecular switches to small groups of neurons in mice.  By "flipping" these switches with chemicals or light, he maps neural circuits and measures the contribution of neurons to innate behaviors such as feeding.

Title of talk:  Hypothalamic Control of Integrative Physiology of Immunity

Tamas L. Horvath DVM, PhD
Jean and David W. Wallace Professor of Comparative Medicine and Professor of Neurobiology and of Obstetrics, Gynecology, and Reproductive Sciences; Chair, Section of Comparative Medicine; Jean and David W. Wallace Professor of Biomedical Research; Director, Yale Program in Integrative Cell Signaling and Neurobiology of Metabolism

 Research interests: Neuroendocrine regulation of homeostasis with particular emphasis on metabolic disorders, such as obesity and diabetes, and the effect of metabolic signals on higher brain functions and neurodegeneration.  We have active research programs to pursue the role of snaptic plasticity in the mediation of peripheral hormones' effects on the central nervous system.  We also study the role of mitochondrial membrane potential in normal and pathological brain functions with particular emphasis on the acute effect of mitochondria in neuronal transmission and neuroprotection.  We combine classical neurobiological approaches, including electrophysiology and neuroanatomy, with endocrine and genetic techniques to better understand biological events at the level of the organism.
