Gina Poe, Ph.D.

Biography

Gina Poe has been working since 1995 on the mechanisms through which sleep serves memory consolidation and restructuring. Dr. Poe is a southern California native who graduated from Stanford University then worked for two post-baccalaureate years at the VA researching Air Force Test Pilots’ brainwave signatures under high-G maneuvers. She then earned her PhD in Basic Sleep in the Neuroscience Interdepartmental Program at UCLA under the guidance of Ronald Harper then moved to the University of Arizona for her postdoctoral studies with Carol Barnes and Bruce McNaughtons looking at graceful degradation of hippocampal function in aged rats as well as hippocampal coding in a 3-D maze navigated in the 1998 space shuttle mission. She brought these multiunit teachings to answer a burning question of whether REM sleep were for remembering or forgetting and found that activity of neurons during REM sleep is consistent both with the consolidation of novel memories and the elimination of already consolidated memories from the hippocampus, readying the associative memory network for new learning the next day. Moving first to Washington State University then to the University of Michigan before joining UCLA in 2016, Poe has over 80 undergraduates, 9 graduate students, and 8 postdoctoral scholars, and has served in university faculty governance as well as led 5 different programs designed to diversify the neuroscience workforce and increase representation of people of the global majority in the STEM fields. At UCLA she continues research and teaching and Directs the COMPASS-Life Sciences and BRI-SURE programs and co-Directs the MARC-U*STAR program. Nationally she has served as course director of the Marine Biological Lab’s SPINES course and co-Directs the Society for Neuroscience’s NSP program which earned the nation’s highest mentoring honor in 2018. These programs have over 1000 PhD level alumni.

Research Interests

The Poe lab investigates the mechanisms by which sleep traits serve learning and memory consolidation. Memories are encoded by the pattern of synaptic connections between neurons. We employ tetrode recording and optogenetic techniques in learning animals to see how neural patterns underlying learning are reactivated during sleep, and how activity during sleep influences the neural memory code. Both strengthening and weakening of synapses is important to the process of sculpting a network when we make new memories and integrate them into old schema. Results from our studies suggest that while synaptic strengthening can be efficiently accomplished during the waking learning process, the synaptic weakening part of memory integration requires conditions unique to sleep. The absence of noradrenaline during sleep spindles and REM sleep as well as the low levels of serotonin during REM sleep allow the brain to integrate new memories and to refresh and renew old synapses so that we are ready to build new associations the next waking period. Memory difficulties involved in post-traumatic stress disorder, Schizophrenia, Alzheimer’s disease and even autism involve abnormalities in the sleep-dependent memory consolidation process that my lab studies. Keywords: Sleep, learning and memory, PTSD, memory consolidation, reconsolidation, REM sleep, sleep spindles, Norepinephrine, LTP, depotentiation, reversal learning, optogenetics, electrophysiology, tetrode recordings, hippocampus, prefrontal cortex.

Beate Ritz, M.D., Ph.D.

Biography

Beate Ritz joined the faculty of the School of Public Health at UCLA in 1995 and is currently Professor and Vice Chair of the Epidemiology Department and holds co-appointments in the Environmental Health department at the UCLA School of Public Health and in Neurology, UCLA School of Medicine; she is a member of the Center for Occupational and Environmental Health (COEH), the Southern California Environmental Health Science Center (SCEHSC), and co-directs the NIEHS-funded UCLA Center for Gene-Environment Studies of Parkinson’s disease.

Dr. Ritz received her MD and a PhD in Medical Sociology from the University of Hamburg Germany in 1983 and 1987; she was a research fellow and resident at the Psychiatric University-Hospital in Hamburg from 1987-1989, and received doctoral training and a PhD degree in Epidemiology in 1995 from UCLA.

Her research focuses on the health effects of occupational and environmental toxins such as pesticides, ionizing radiation, and air pollution on chronic diseases including neurodegenerative disorders (Parkinson’s disease), cancers, and adverse birth outcomes and asthma. She previously investigated the causes of cancer in chemical toxin and radiation exposed workers and assessed the impact of ergonomic work-place factors on musculo-skeletal disorders. For the past decade, she studied the effects of air pollution on adverse birth outcomes as well as asthma in children in Southern California. In 2006, she received the Robert M Zweig Memorial award for outstanding achievement in air quality and medicine from the South Coast Air Quality Management District. She also spend the past 15 years investigating the long-term effects of pesticide exposures on Parkinson’s disease and cancers and is currently conducting a project to implement a Parkinson’s disease registry required by a new law in California.

In her research she uses geographic information system (GIS) modeling of environmental exposures including pesticide use and traffic related air pollution in California and investigates links between genetic susceptibility factors and environmental exposures in populations. She is directing and collaborating in a large number of federally (NIH, DOD), state (California Air Resources Board), and foundation (Michael J Fox Foundation) funded research projects.

Felix Schweizer, Ph.D.

Biography

Felix E. Schweizer was born in Basel, Switzerland and conducted his graduate research in the laboratory of Prof. Max M. Burger under the direction of Dr. Theo Schafer. He received his PhD degree in biochemistry summa cum laude from the University of Basel in 1989. From 1990 to 1994, he was a post-doctoral fellow in the Department of Molecular and Cellular Physiology at Stanford University in the laboratory of Prof. Richard W. Tsien. From 1994 to 1998, he was postdoctoral fellow in the Department of Neurobiology at Duke University in the laboratory of Professor George J. Augustine. Dr. Schweizer joined the Department of Neurobiology in the David Geffen School of Medicine at UCLA in 1998 as Assistant Professor and was promoted to Full Professor in 2010. Dr. Schweizer’s research interests concern the molecular mechanisms by which neurons communicate, the regulation of communication by neurons and how alterations in neuronal communication might contribute to neuronal diseases. The Schweizer laboratory uses electrophysiological and optical tools to investigate the dynamic molecular mechanisms underlying the regulation of neurotransmitter release. We are particularly interested in the role of protein ubiquitination in regulating neuronal excitability and synaptic transmission. In collaboration with Dr. James Wohlschlegel, we used multiplexed SILAC and identified synaptic proteins that are dynamically regulated. More recently, in collaboration with Dr. David Krantz, we are using pesticides linked to neuro-degenerative disorders as unbiased tools identify novel pathways that might be involved in early signs of degeneration. In addition, we are characterizing transmission at the first synapse of the vestibular system, i.e. between utricular sensory hair cells and primary afferent neurons. In collaboration with Dr. Larry Hoffman we are finding that changing the gravitational load alters synaptic structures. We are now using serial EM and EM tomography in addition to physiology and cell biology to define in more detail the transfer function between head-movement input and afferent nerve-firing output.

Steve Shoptaw is a licensed psychologist and Professor in the UCLA Departments of Family Medicine and Psychiatry and Biobehavioral Sciences. Dr. Shoptaw joined the Department of Family Medicine as full professor in 2005. Prior to this, Dr. Shoptaw was a Research Psychologist with the Integrated Substance Abuse Program in the Dept. of Psychiatry & Behavioral Science since 2003. Dr. Shoptaw earned his BA (1982) in Psychology and MA (1985) and Ph.D. (1990) in Psychology at UCLA. His dissertation was nominated for the Gingerelli Award for Excellence in the Department of Psychology. Dr. Shoptaw completed his postdoctoral training in Psychophysiology at the UCLA NPI/VAMC in Sepulveda, CA in 1991. Following that, Dr. Shoptaw worked for 10 years as a Principal Investigator with Friends Research Institute, Inc., during which time, his program of clinical research with substance abusers supported opening several treatment research clinics in Rancho Cucamonga, Hollywood, South Los Angeles, and West Hollywood. Dr. Shoptaw received the FRI Daniel Mendelsohn Young Investigator Award in 1996 and a mentoring award in 2000. In 1996, Dr. Shoptaw opened Safe House, a 24 bed facility that provides emergency, transitional and permanent housing to persons living with HIV/AIDS, chemical dependency, transitional and permanent housing to persons living with HIV/AIDS, chemical dependency, and mental illness who are homeless or at risk for homelessness. He continues with this program as a volunteer Executive Director. These linkages of clinical research and community collaboration have led Dr. Shoptaw???s work to influence practice guidelines in intervening with substance abusers, especially those at high risk for HIV transmission, locally, nationally and in emerging international epidemics.
