Dr. Katie Witkiewitz is a Professor of Psychology at the University of New Mexico with a joint appointment at the Center on Alcoholism, Substance Abuse, and Addictions.  The underlying theme of her research is the development of empirically-based models of alcohol use disorder, with an emphasis on harm reduction and the application of person-centered models to better understand individual changes in alcohol use over time.  Her recent work has focused on novel definitions of alcohol use disorder treatment outcomes that focus on reductions in drinking, as an alternative to an abstinence-only model of alcohol recovery.

Dr. Witkiewitz is also a licensed clinical psychologist and has worked extensively on the development of a theoretical model of biopsychosocial influences on alcohol use and relapse.  This research has led to her collaborative work on the development and evaluation of mindfulness-based interventions for alcohol and drug use disorders.  She has conducted numerous empirical studies on the prediction of alcohol and drug relapse following treatment, mechanisms of successful alcohol treatment outcomes, as well as the development of behavioral interventions to treat addiction.  Her research has been supported by grants from the National Institute on Mental Health, the National Institute on Drug Abuse, the National Institute on Alcohol Abuse and Alcoholism and the National Cancer Institute, totaling over $22 million in research funding since 2004.   

Dr. Witkiewitz was born in Rochester New York and graduated Summa Cum Laude with a Bachelor of Arts degree in psychology from the State University of New York at Potsdam in 1999. She completed a Masters of Arts degree at the University of Montana in 2000 and her doctoral degree at the University of Washington in 2005 under the direction of Dr. G. Alan Marlatt. To date, she has authored 5 books, over 185 peer-reviewed publications and book chapters, and she has given over 75 presentations and invited talks.

alcohol tolerance, Alcohol Consumption, genetics and addiction, Neurobiology

Professor, Department of Pharmacology, University of Colorado School of Medicine, Aurora, CO.

Research has focused on neural mechanisms of adaptation to alcohol, including tolerance and dependence.  Identified a  role of peptide hormones and brain growth factors to modify alcohol tolerance.  

Discovered that one subtype of glutamate receptor, the NMDA receptor, is very sensitive to alcohol, and that increases in NMDA receptor function are involved in alcohol dependence.  This work has led to many further studies by others that focus on the role of the brain  glutamate systems in addiction to alcohol and other drugs.  

Currently focus on systems genetic analysis, using "big data" to understand the genetic contribution to alcohol-related and other complex behaviors.

Kenneth Sher, PhD

Curators' Distinguished Professor

Research Society on Alcoholism

Alcohol

Kenneth J. Sher, Ph.D., is a nationally renowned scholar, researcher, and mentor whose work has greatly advanced our understanding of the etiology and course of alcohol use disorder (AUD), particularly as it relates to personality traits and their evolution. Dr. Sher has been at the forefront of research on personality, alcohol misuse among college students, and the behavioral pharmacology of alcohol. He is also a highly regarded expert in longitudinal research methodology. Over the course of his career, Dr. Sher has studied a wide range of topics contributing substantially to our understanding of the development of alcohol and other substance misuse. He has examined risk mechanisms that influence AUD onset and progression, premorbid predictors of future AUD (e.g., cognitive mechanisms and individual differences in the psychopharmacological responses to alcohol), and the involvement of family history of alcoholism in multiple etiological pathways to AUDs. 

His diverse research interests include: personality, as well as developmental changes in personality, as predictors of alcohol misuse and AUD; gene-environment interactions in the development of AUD; and predictors and consequences of binge drinking and alcohol misuse among college students (including 21st birthday drinking and other extreme drinking occasions). Dr. Sher has also investigated the phenomenon of “maturing out” of alcohol problems, demonstrating that maturing out is associated with differences in age-related personality changes that are accompanied by decreased impulsivity and neuroticism and is not merely a consequence of constrained opportunity occasioned by the assumption of adult roles. 

Dr. Sher had led two major ongoing longitudinal cohort studies that have followed individuals beginning in their freshman year of college and into mid-life. In addition to the development of AUD, this research tracks drug use and comorbid psychiatric disorders. A particularly innovative aspect of this work is the incorporation of genotyping which may provide key information on individual differences in susceptibility to AUD. 

In addition to using traditional survey approaches, Dr. Sher’s research employs event-based data to capture the momentary moods, motivational states, and cues that precede drinking events. This work is critical to understanding transient influences on drinking behavior and related consequences on a given occasion. 

A major focus of his current work is the critical evaluation of existing diagnostic approaches and development of empirically-based criteria and algorithms for AUD diagnosis. This research holds promise for improving AUD diagnosis in clinical practice, and advancing research on the causes and correlates of AUD.

Dr. Sher has been continually funded by NIAAA for more than 30 years. He has had more than 250 papers published in peer-reviewed journals and he has authored and edited several books. 

Dr. Sher earned his undergraduate degree from Antioch College, his Ph.D. in clinical psychology from Indiana University, and completed clinical internship training at Brown University. He is the Curators’ Distinguished Professor of Psychological Sciences at the University of Missouri, where he directs a pre and postdoctoral training program in alcohol research.

Alcohol, Alcoholism, Drug Abuse, Mental Health

Tom Greenfield, PhD, is Scientific Director of the Public Health Institute’s Alcohol Research Group, in Emeryville California, which involves 15 multi-disciplinary research scientists bringing a broad range of expertise to bear on alcohol, other drug and mental health problems.  Since 1995 Greenfield led and now co-lead the bi-decadal National Alcohol Surveys (NASs) conducted by the NIAAA-funded National Alcohol Research Center, that he directed from 1999 to 2015 (P50 AA005595, Years 20-35). Over time, the NAS has incorporated measures and interview modalities that he helped refine in a series of methodological studies.  Greenfield trained as a clinical psychologist, afterwards adding epidemiological and health services expertise in part through postdoctoral years at the UCSF Department of Psychiatry.  Educated at Caltech, MIT and the University of Michigan, he has authored or coauthored over 250 peer-reviewed articles, chapters, books and monographs.  Many are on health effects of alcohol and alcohol policy, often in collaboration with senior colleagues, early career scientists, and postdoctoral fellows.  In addition to participating in many national and international projects, Dr. Greenfield has led numerous R-mechanism National Institutes of Health projects on such topics as alcohol policy evaluation, health disparities and alcohol-related mortality, alcohol intake measurement, and comparative cross-national studies.  He currently leads two team-based Alcohol's Harms to Others R01 grants funded by NIAAA. One, together with his ARG colleague Dr. Katherine Karriker-Jaffe, examines ways that secondhand drinking can victimize partners, families, children, coworkers, and communities, using metrics such as the damage to mental health, health quality of life, and a family’s finances.  A second is a similar multinational collaboration involving standardized questionnaires in over 30 countries that surveyed victims and perpetrators of alcohol’s harms, and involves multiple PIs and 15 international co-investigators.  Both grants are examining in depth state and national policies, contextual, and protective influences, and ways to best reduce the toll of alcohol’s harms to communities.

Gene Expression and Regulation, Drug Discovery, Receptor Proteins, immune signaling, Neuroscience

I have almost 40 years of experience in the field of alcoholism research, with much of my work focusing on the molecular sites and mechanisms of alcohol action in brain. My group has extensive experience with mouse behavioral models of alcohol consumption and dependence and was involved in some of the initial studies of the neuroimmune basis of alcohol dependence. Profiling brain gene expression is key to understanding addiction, and we were among the first to study the human brain transcriptome. We have implemented microRNA profiling and next-generation sequencing to extend our studies of molecular remodeling by alcohol in human and mouse brain. We study the genetic overlap in human alcoholics and animal models of alcohol dependence and examine the neurobiological systems involved. My research encompasses the fields of genomics, behavior, systems biology, and bioinformatics. Overall, my work has combined functional, structural, behavioral, and genomic approaches to define sites of alcohol action. Currently, I am Associate Director of the Waggoner Center for Alcohol and Addiction Research at The University of Texas at Austin and previously served as Director for 20 years. I am also the Consortium Director for the Integrative Neuroscience Initiative on Alcoholism (INIA)-Neuroimmune, where our goal is to identify and test candidate drugs that may be repurposed to treat alcohol use disorders.

Chang's work focuses on the therapy resistance of cancer stem cells, which has led to several publications and international presentations. Her clinical research aims to evaluate novel biologic agents in breast cancer patients. Chang has worked in the field of tumor-initiating cells for more than 10 years. After her discovery that tumor-initiating cells are chemo-resistant, and that targeting the EGFR/HER2 pathway can decrease this subpopulation, Chang played a key role in demonstrating some of the limitations and mechanisms of tumor-initiating cells. Her work is now focused on the mechanisms that regulate TICs, as well as initiating and planning clinical trials that target this critical tumor initiating subpopulation. She is also interested in characterizing the cross-talk between these different pathways that may lead to mechanisms of resistance, and has identified some of the chief regulatory pathways involved in TIC self-renewal. She is a world-renown clinical investigator, credited as one of the first to describe intrinsic chemo-resistance of tumor-initiating cells.

Erica Ollmann Saphire, Ph.D. serves as President and CEO of the La Jolla Institute for Immunology. She is one of the world’s leading experts in pandemic and emerging viruses, such as Ebola, Marburg and Lassa. Dr. Saphire directs the Viral Hemorrhagic Fever Immunotherapeutic Consortium (VIC), an NIH-funded Center of Excellence in Translational Research. The VIC unites 43 previously competing academic, industrial and government labs across five continents to understand which antibodies are most effective in patients and to streamline the research pipeline to provide antibody therapeutics against Ebola, Marburg, Lassa and other viruses. Dr. Saphire's research explains, at the molecular level, how and why viruses like Ebola and Lassa are pathogenic and provides the roadmap for developing antibody-based treatments. Her team has solved the structures of the Ebola, Sudan, Marburg, Bundibugyo and Lassa virus glycoproteins, explained how they remodel these structures as they drive themselves into cells, how their proteins suppress immune function and where human antibodies can defeat these viruses. A recent discovery revealed why neutralizing antibodies had been so difficult to elicit against Lassa virus, and provided not only the templates for the needed vaccine, but the molecule itself: a Lassa surface glycoprotein engineered to remain in the right conformation to inspire the needed antibody response. This molecule is the basis for international vaccine efforts against Lassa.

Dr. Saphire is the recipient of numerous accolades and grants, including the Presidential Early Career Award in Science and Engineering presented by President Obama at the White House; the Gallo Award for Scientific Excellence and Leadership from the Global Virus Network; young investigator awards from the International Congress of Antiviral Research, the American Society for Microbiology, American Society for Biochemistry and Molecular Biology, and the MRC Centre for Virus Research in the United Kingdom; the Investigators in the Pathogenesis of Infectious Disease Award from the Burroughs Wellcome Fund, and the Surhain Sidhu award for the most outstanding contribution to the field of diffraction by a person within five years of the Ph.D. Dr. Saphire has been awarded a Fulbright Global Scholar fellowship from the United States Department of State and a Mercator Fellowship from the German research foundation, Deutsche Forschungsgemeinschaft, to develop international collaborations around human health and molecular imaging through cryoelectron microscopy.

Dr. Saphire received a B.A. in biochemistry and cell biology and ecology and evolutionary biology from Rice University in Houston, Texas, and a Ph.D. in molecular biology from Scripps Research. She stayed on at Scripps Research as a Research Associate to conduct postdoctoral research and rose through the ranks to become a Professor in the Department of Immunology and Microbiology. In early 2019, Dr. Saphire joined La Jolla Institute for Immunology to establish a molecular imaging facility for cryo-electron microscopy (cryo-EM) at the Institute. The extremely detailed images produced by cryo-EM reveal precisely how essential mechanisms of the immune system operate.

Urology, Urologist, Physician

Dr. Steve Hodges, a pediatric urologist who practices in Winston-Salem, NC, is a leading expert when it comes to children and issues related to toilet training, bedwetting and constipation. His own published research shows that children trained before age 2 have a much higher risk of having accidents compared to those trained later and are more likely to become habitual holders of their pee and poop, which can lead to issues with constipation.

Hodges can discuss how today's today’s modern parents feel societal and financial pressure to toilet train their children before they are developmentally and physically ready. In his opinion, few children are ready to be fully toilet trained before the age of 3.
 
He can discuss how diet affects children's bowel systems: what goes in (food) determines what comes out (poop). A diet full of highly processed foods like crackers, chicken nuggets and hotdogs without lots of vegetables, fruits and fibers often leads to constipation.
 
Hodges can discuss how improper poop or pee posture can affect children's ability to fully eliminate: When it comes to pooping, it’s not enough to have a cute little seat in place because a “squatting” position improves childrens’ ability to fully eliminate. They need to sit on the toilet with their feet on a tall stool, leaning forward, elbows on knees.

And, he can address how parents and caregivers should not ASK if their child has to go to the bathroom because they will likely say NO because they don’t want to stop whatever activity they are involved in. Instead, children should be directed to attempt to pee about every two hours and should be encouraged in a way that works for them individually.
 
When children hold their pee at this young age, this actually leads to smaller bladder capacity which can lead to problems like bedwetting.

“I don’t predict a hurricane season. If a hurricane makes landfall near where you live, that is an active season for you,” says URI Professor of Oceanography Isaac Ginis. Yet predicting the severity of a hurricane can mean the difference between life and death, which is why Ginis makes it his business to predict the power of these ferocious storms. He developed a computer model so successful it was adopted by the National Weather Service. As one of the few scientists worldwide to show the role the ocean plays in hurricanes, Ginis essentially proved that ocean temperature is the most important factor in hurricane intensity and power. Ginis’s research efforts have resulted in pioneering advances in modeling of the tropical cyclone-ocean interactions that have led to significant improvements in hurricane intensity forecast skills. His research group has contributed to the development of the Hurricane Weather Research Forecast model used by the U.S. National Hurricane Center and Joint Typhoon Warning Center for operational forecasting of tropical cyclones in all ocean basins. One of his team’s most recent projects, the Rhode Island Coastal Hazards, Analysis, Modeling and Prediction (RI-CHAMP) system, advances storm model capabilities and develops a real-time hazard and impact prediction system for hurricanes and nor'easters in Southern New England. The system provides actionable information to decision makers in helping to prepare for a storm. When it comes to forecasting hurricanes, the focus is usually on more tropical locales. However, Ginis says, “the farther they move to the north, the more complex they become.”
