Why Stability Matters for Early Childhood Development
Join the Center on the Developing Child’s upcoming webinar to explore why stability plays a critical role in shaping young children’s health and development.
Drawing on insights from the new working paper, From Resources to Routines: The Importance of Stability in the Developmental Environment, the conversation will examine how stability—or the lack of it—across children’s developmental environments can affect their well-being in the moment and across the lifespan, and highlight strategies to promote stability for young children and their caregivers.
The conversation will be moderated by our Chief Science Officer, Lindsey Burghardt, MD, MPH, FAAP, and feature Nathaniel Harnett, PhD, Assistant Professor in Psychiatry at Harvard Medical School, and Natalie Slopen, ScD, Associate Professor of Social and Behavioral Sciences at Harvard T. H. Chan School of Public Health.

CHDS Seminar with Christopher Jackson
Join the Center for Health Decision Science for a seminar with Christopher Jackson from the University of Cambridge, UK, titled, “Making Semi-Markov Multistate Models for Intermittent Observations Easily Usable.” Multi-state models for changes in a state (e.g. of health or illness) often assume that the transition rate is constant with time spent in the state (the “Markov” assumption). In this seminar, Jackson proposes a new method and software package to relax this often-unrealistic assumption, using hidden states known as “phases.” This is motivated by applications such as modelling the duration of infections, modelling time in a detectable state in cancer screening, and modelling cognitive impairment in studies of ageing.
Christopher Jackson is a Senior Statistician at the MRC Biostatistics Unit, University of Cambridge. His research involves incorporating statistical methods in models to combine evidence to inform population health policy. His publications cover Bayesian evidence synthesis, survival analysis, multi-state modelling, longitudinal data, decision theory, and model comparison. He has also developed several popular R packages, and co-authored two textbooks, “The BUGS Book” and “Value of Information for Healthcare Decision-Making.”

Center Member Research Presentation: Hannah Healy, PhD
Join us for a Center Member Research Presentation by Dr. Hannah Healy. Following a brief presentation entitled “Monitoring microbial risks from tap to sewer,” there will be time for all participants to engage in a cross-disciplinary discussion with Dr. Healy and each other.
Summary: Drinking water and wastewater infrastructure are vital to the protection of human health. In this talk, Dr. Healy will discuss how understanding drinking water microbiomes can help prevent waterborne opportunistic infections and how surveilling wastewater metagenomes can serve as a leading indicator of disease prevalence. Finally, she will present the H2O Lab’s current research initiatives and initiate a discussion on synergies with other NIEHS Center research.
About the speaker: Dr. Hannah Greenwald Healy is an Assistant Professor of Environmental Health and Exposure Science at the Harvard T.H. Chan School of Public Health with a secondary appointment in Environmental Science and Engineering in the School of Engineering and Applied Sciences. She runs the Healy Health ‘Omics (H2O) Lab, which aims to improve public health by monitoring and controlling pathogens and their broader microbiomes in engineered water systems. Dr. Healy is trained as an Environmental Engineer, receiving her BS from Georgia Tech and MS and PhD from the University of California, Berkeley. Prior to her faculty appointment, she completed a Gaylord Donnelley Postdoctoral Fellowship at Yale University.
This event will be held in person in HSPH Bldg. 1, 1302 and via Zoom. Register here

Housing and homelessness: Solutions at the intersection of public health and public safety
Presented jointly with the Initiative on Health and Homelessness
As the cost of living rises across the United States, a record number of people experienced homelessness in 2024*, and shelter, housing, and support services are struggling to meet the need. Join leaders across public health and public safety for a conversation that moves beyond emergency response toward prevention, housing-first strategies, and long-term solutions. Grounded in lived experience and evidence, this panel explores cross-sector solutions with a focus on dignity, safety, and sustainable housing.

Abstract
It is well established that the environment during pregnancy can have a long-term impact on cardiometabolic and neurodevelopmental outcomes in offspring and increase risk of non-communicable diseases (NCDs) in later life. There is growing evidence from preclinical studies and some clinical studies that the preconception period in both females and males and the early pregnancy phase are periods of high sensitivity to environmental perturbation. The Healthy Life Trajectories Initiative (HeLTI) was developed to translate new knowledge in the area of developmental origins of health and disease (DOHaD) and improve the health of mothers, infants and children. The HeLTI consortium includes harmonized trials in Canada, China, India and South Africa designed to evaluate the impact of an integrated evidence-based intervention package, delivered through the preconception, pregnancy and postnatal period on, 1) reducing adiposity and obesity, and improving neurodevelopmental and cardiometabolic development in infants and children to 5-years of age and, 2) improving maternal health and pregnancy outcomes. All trials have completed recruitment and combine harmonized data and biospecimen collection. The HeLTI-India trial will be described in detail. Findings from the HeLTI studies will have profound implications for public health policy but will also allow determination of the mechanisms that underlie intergenerational transmission. HeLTI is funded by the Canadian Institutes for Health Research and International funding agencies (India, China and South Africa) and is partnered with WHO.
About the speaker
Stephen Matthews, PhD, FCAHS, is Canada Research Chair in Early Development and Health, Professor of Physiology, Ob-Gyn and Medicine at the University of Toronto and a Senior Scientist at the Lunenfeld-Tanenbaum Research Institute, Sinai Health. He served as Chair of the Department of Physiology (UofT; 2007-2014). He is currently Director of Research at the Alliance for Human Development, LTRI, and Director of the Ontario Birth Study. Matthews is also the Canadian lead PI of the CIHR/DBT-funded Healthy Life Trajectories (HeLTI) trial in India.
His fundamental research program is determining mechanisms by which early interventions and exposures can impact long-term neurologic and endocrine function in offspring across multiple generations. With a focus on epigenetics, his research team is determining the molecular mechanisms by which this occurs. In a parallel program, his group is investigating drug and hormone transport mechanisms in the placenta and fetal brain, with a focus on developing novel treatments to protect the developing fetal brain.
Professor Matthews is committed to translating fundamental research to improve human health. In addition to leadership of the HeLTI-India trial and the Ontario Birth Study, he co-founded the MAVAN program, which followed neurocognitive development in children following adverse early experience. He has secured over $40M in research funding, published 265 full papers and has received >300 invitations to present his work around the world. He was elected a Fellow of the Canadian Academy of Health Sciences (2019). He has served as elected President of the Society for Reproductive Investigation. In 2015, he co-founded DOHaD Canada and served as elected President (2018-23).
