This event will be held in person (HSPH Bldg. 1, 1302) and via Zoom. Register here
About the speaker
Dr. William Mair is a Professor of Molecular Metabolism at Harvard, and Director of the Harvard T.H. Chan Healthy Aging Initiative. He received his BSc in Genetics and PhD in Biology from University College London, and completed his postdoctoral training at the Salk Institute for Biological Studies in La Jolla, CA. The Mair lab studies mechanisms that mitigate the risks of aging, with a focus on metabolism and how changes to food intake can impact the aging process. They are defining how nutrient and energy sensors in cells become dysfunctional with age, leading to metabolic inflexibility and accelerated aging. Dr. Mair’s work aims to develop therapeutics that maintain healthy metabolic function, thereby enabling our bodies to process the food we eat effectively as we age to prolong healthy aging. Dr. Mair has won numerous awards for his work on aging and geroscience, including the American Federation Breakthrough in Gerontology Award, the Glenn Medical Foundation for Medical Research Scholar Award and the Ellison Medical Foundation New Scholar in Aging Research Award. He is co-founding director of the MBL Biology of Aging Summer Research Course, and organizes several international conferences on geroscience and aging biology.

Center Member Research Presentation: Peng Gao, PhD
Join us for a Center Member Research Presentation by Dr. Peng Gao on Mapping the human exposome: From population pattern to cellular resolution. Following a brief presentation, there will be time for all participants to engage in a cross-disciplinary discussion with Dr. Gao and each other.
Summary: This presentation will explore cutting-edge approaches in environmental health that integrate chemical exposomics with multi-omics technologies to understand how environmental exposures influence human health. Dr. Gao will discuss our recent work on precision environmental health monitoring, including longitudinal profiling of personal exposomes and their connections to disease outcomes, with particular emphasis on applications in cancer, neurodegeneration, and respiratory health research. The talk will highlight opportunities for cross-disciplinary collaboration in advancing exposome science across scales, from population-level patterns to individual monitoring and down to molecular and cellular mechanisms.
About the speaker: Dr. Peng Gao is an Assistant Professor of Environmental Health and Exposomics at Harvard T.H. Chan School of Public Health. His research focuses on characterizing the human exposome, the totality of environmental exposures and their biological responses, and understanding its role in chronic disease development. Dr. Gao’s lab develops and applies advanced analytical chemistry and computational approaches to measure chemical and biological exposures in environmental and biological samples, integrating these with multi-omics data to investigate disease etiology. Before joining Harvard, he was an Assistant Professor at the University of Pittsburgh School of Public Health and completed his postdoctoral training at Stanford University School of Medicine.

U.S. Life Table Program: Data Challenges, Methodological Solutions, and Moving into the Future
Join us on Wednesday, November 19th for the Epidemiology Seminar Series, featuring Dr. Elizabeth Arias discussing U.S. Life Table Program: Data Challenges, Methodological Solutions, and Moving into the Future.
Abstract: The presentation will provide a historical overview of the U.S. Life Table Program and a summary of the data challenges and methodological solutions employed over the years. The talk will include a description of the US National Vital Statistics System with its inherent challenges and limitations. Specific topics covered will include old age data quality, racial and ethnic misclassification, and small geographic area estimates. The goals for the future of the program will be discussed.
Bio: Dr. Elizabeth Arias is the Director of the US Life Table Program and the Mortality Statistics and Research Team Lead in the Division of Vital Statistics, at the National Center for Health Statistics (NCHS). Dr. Arias received her Ph.D. in Sociology (Demography) from the University of Wisconsin-Madison. At NCHS, Dr. Arias has worked to expand the US Life Table Program’s racial, ethnic, and geographic coverage, developing methods to address data quality limitations. Under her leadership, the program has expanded from two race groups to five race and Hispanic origin populations, annual state life tables, and life tables by census tracts. Dr. Arias also conducts research on racial and ethnic mortality disparities with a special focus on the Hispanic population.

Brown Bag Seminar: Thyroid cancer prevention in radiological emergencies
Yoshitaka Nishikawa, MD, PhD, is a physician-scientist, Takemi Fellow at Harvard T.H. Chan School of Public Health, and associate professor at Kyoto University Graduate School of Medicine. His work focuses on developing and disseminating health information to protect people from disasters and diseases, particularly cancer and gastrointestinal diseases. He leads two reporting guidelines: CAST-D (case studies in public health and medicine related to disasters) and WATER (wastewater analysis and tracking in epidemiological reporting). His Takemi project examines stable iodine implementation after radiological emergencies at individual, community, and national policy levels.

Brown Bag Seminar: The air we share: Lessons from a career in pulmonary and global health research
William Checkley is a physician-scientist and global health expert whose research focuses on chronic respiratory diseases, particularly chronic obstructive pulmonary disease (COPD), in low- and middle-income countries (LMICs). He is a professor of medicine at Johns Hopkins University with joint appointments in International Health and Biostatistics, and he directs the Center for Global Non-Communicable Disease Research and Training. He has authored >400 publications in peer-reviewed journals, with more than 24,000 citations and an h-index of 77.
Checkley’s work addresses the global burden of COPD, which disproportionately affects LMICs. His work spans a wide spectrum—from observational cohort studies identifying risk factors such as household air pollution and low lung growth and development, to randomized controlled trials testing interventions to improve disease outcomes in real-world settings. In collaboration with international partners, Checkley has led studies like the Global Excellence in COPD Outcomes (GECo) trial, which evaluates the effectiveness of community health worker-delivered self-management interventions for COPD in Nepal, Peru, and Uganda. These studies aim to improve COPD care in underserved populations. He has also developed and validated simple, cost-effective screening tools for COPD to facilitate early diagnosis and management in resource-limited settings.
Checkley is also committed to building research capacity in LMICs. He co-leads Fogarty International Center-funded training programs in Peru and elsewhere, focusing on environmental exposures and chronic pulmonary diseases, to mentor the next generation of researchers in these regions. Through his work, Checkley aims to reduce the global burden of chronic respiratory diseases by developing scalable, evidence-based interventions and fostering international collaborations.
