Megan Goldberg

Assistant Professor of American Politics

Cornell College

American Politics, Elections & Campaigns, Public Opinion Poll

Assistant Professor of Politics at Cornell College in Mount Vernon, Iowa. Ph.D. in 2019 from the department of political science at the Massachusetts Institute of Technology, graduate student affiliate of the MIT Political Methodology Lab. Studies American politics, focusing on state politics, political messaging, public opinion, and quantitative methodology.

Her work examines the dynamics of state politics in an increasingly nationalized context. Studies how governors and state parties shift their rhetoric towards elections, and how the mass public reacts to such shifts.  Looks for changes in ideological heterogeneity among political elites as elections approach, and how often governors use national politics to frame issues. Finally, examines the public’s response to the governor’s “going national.” Uses social media data, text analysis, and survey experiments to answer these questions.

Research addresses the relevance and consequences of a federal system when it comes to state politics and political behavior. This question is increasingly important as we are faced with evidence that state political idiosyncrasies are disappearing.

Methodologically, work looks to bring text and social media to answer this question in ways we are unable to do with existing data sources, such as state of the state addresses or state party platforms.

Dr. Raphael Gottardo is a computational biologist who specializes in applying rapidly evolving ideas in data science to solving problems in cancer and related diseases. As scientific director of the Translational Data Science Integrated Research Center, he is at the center of the busy intersection of biology, data science and technology at Fred Hutchinson Cancer Research Center.

His goal is to expand data-driven innovations for patients by cultivating a cross-disciplinary environment in which doctors and laboratory scientists work seamlessly with their colleagues in biostatistics and computational sciences to take advantage of the flood of information made possible by advanced technologies. 

The aim is to bring scientific discoveries from research labs to the bedside sooner using data-driven approaches. To do so, bench scientists and clinical researchers from many corners of the Hutch work collaboratively with experts in data science.

Much of his work is focused on profiling the cellular components of the human immune system – using data science to understand how to make immunotherapies work better for patients. 

“It’s when you get into the details that it really becomes interesting,” he said. “The immune system is very complex, and it turns out we don’t know a whole lot about it yet. Looking at these single-cell technologies generating massive amounts of data has brought me to really cool statistical and computational challenges.”

Dr. Gottardo’s own research involves the development of computational tools for vaccine and immunology studies, including high-throughput experiments that may use flow cytometry or high-speed genome sequencing. His current studies include:
•	Statistical and computational analysis of flow cytometry data
•	Development of statistical and computational methods for single-cell genomics
•	Immune responses to malaria and HIV infection and immunization within the Human Immunology Project Consortium (HIPC)
•	Development of the HIPC database and research portal (
•	Contribution to the Bioconductor project, an open computing resource for genomics
•	Leadership for the Vaccine and Immunology Statistical Center of the Collaboration for AIDS Vaccine Discovery of the Bill and Melinda Gates Foundation
•	Leadership for the Vaccine Statistical Support (VSS) Global Health Vaccine Accelerating Platform (GH-VAP) of the Bill and Melinda Gates Foundation

Dr. Gottardo is the J. Orin Edson Foundation Endowed Chair at Fred Hutch and a member of the Vaccine and Infectious Disease and Public Health Sciences Divisions. He, along with other Fred Hutch researchers, is co-leading a collaboration with the Allen Institute for Immunology to chart the human immune system by harnessing big data and emerging technologies.

An affiliate professor of statistics at the University of Washington, he teaches courses in stochastic modeling, bioinformatics and statistical computing and supervises biostatistics and statistics doctoral students on statistical-methods research for high-dimensional omics data analysis

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.
