Title Talk
The Role of Plumbing Biofilms in Healthcare Acquired Infections
THIS SPEAKER WILL BE IN PERSON IN FXB 301.
The event will be hybrid.
Speaker Information
Plumbing systems provide ideal growth conditions for polymicrobial biofilms that often contain health-relevant microorganisms. In hospitals, where 1 in 31 patients contracts a healthcare acquired infection, biofilm control is of the utmost importance for infection prevention. In this seminar, Hannah Greenwald Healy, Assistant Professor of Environmental Health and Exposure Science, will present research from several sampling campaigns at Yale New Haven Hospital. Using a combination of metagenomic and culture-based methods, she and her team investigated plumbing biofilms throughout water systems, with broad implications for infection prevention and wastewater surveillance.

The Big Joy Project: Using Daily Microacts to Promote Global Well-Being
On Wednesday, March 11th, 2026, from 1-1:50 PM in FXB G13 and online, we held the fifth installment in our Virtues for Well-being seminar series, featuring leading expert on joy Dr. Emiliana Simon-Thomas.
Event Description
Greater well-being predicts better health, more satisfying relationships, and overall success in life – and it is of utmost importance to most people. Recent scholarship has yielded a growing canon of empirically-tested interventions to enhance well-being, though few are multifaceted or widely, freely accessible. This presentation will share insights from the Big JOY project, an interactive public online program that offers 7 daily well-being micro-acts alongside individualized feedback about momentary and pre-to-post impact. A global, collaborative Citizen Science initiative, analysis of voluntary single-arm Big JOY participant responses sheds light on key patterns of engagement and impact; financial strain predicts drop off, younger people report greater benefit to well-being, and greater adherence ties to stronger endorsement of prosocial mores. Published findings and ongoing examination of the Big JOY dataset promise to inform continued efforts to promote well-being effectively, sustainably, and at scale.

On Thin Ice: stories of trust (and mistrust) in Arctic research and policy
The Office of Field Education and Practice is pleased to host the first Community Engaged Learning Seminar with colleagues from the Harvard Arctic Initiative.
Moderated by Sappho Gilbert, postdoctoral research fellow at Harvard Chan School and research fellow at the Arctic Initiative, this panel will explore the role of trust in research and policy with Arctic communities, focusing on how it is built, sustained, and at times lost and rebuilt. Drawing on examples from knowledge co-production and community engagement, governance, health care, food systems, and infrastructure, panelists will detail the risks of broken trust and the potential of lockstep, community-centered partnerships. Panelists include Harvard Chan student and Rose Service Learning Fellow, Kenzo Kimura and Fulbright Scholars at the Arctic Initiative, Alexandra Middleton, Hans Peder Kirkegaard and Juho Kähkönen.

Metabolic flexibility and healthy aging with William Mair, PhD
Please join the Harvard Chan NIEHS Center for Environmental Health and the Department of Environmental Health for a talk by William Mair, PhD, of the Harvard T.H. Chan School of Public Health. Dr. Mair will discuss “Metabolic flexibility and healthy aging.”
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.
