Events will be hosted January – December, 2025, usually on the last Wednesday of every month, 12:00 – 14:00 pm ET. Presented over Zoom.
After each talk, we will continue the discussions in an informal social meeting with MSE. All speakers and members of the audience are welcome to join the social meeting.
Hosted by: Sue Ishaq, MSE, and finacially supported by the University of Maine Institute of Medicine and the UMaine Cultural Affairs/Distinguished Lecture Committee.
Summary:
Microorganisms are critical to many aspects of biological life, including human health. The human body is a veritable universe for microorganisms: some pass through but once, some are frequent tourists, and some spend their entire existence in the confines of our body tissues. The collective microbial community, our microbiome, can be impacted by the details of our lifestyle, including diet, hygiene, health status, and more, but many are driven by social, economic, medical, or political constraints that restrict available choices that may impact our health. Access to resources is the basis for creating and resolving social equity—access to healthcare, healthy foods, a suitable living environment, and to beneficial microorganisms, but also access to personal and occupational protection to avoid exposure to infectious disease. This speaker series explores the way that microbes connect public policy, social disparities, and human health, as well as the ongoing research, education, policy, and innovation in this field.

“Healthy Soils: Our Hope for a Warming World”
Dr. Kristen DeAngelis, PhD
Sept 24, 2025 12:00 EDT. This event has passed, watch the recording here.

Kristen got her PhD in Microbiology from the University of California Berkeley, and was trained in microbial ecology and environmental microbiology as a postdoc at the Lawrence Berkeley National Laboratory and at the Joint BioEnergy Institute. Born in Massachusetts, she has worked at UMass Amherst since 2011, where she is the lead of the Molecular Microbial Ecology Lab in the department of Microbiology. In the past 5 years alone, she became an Elected Fellow of the American Academy of Microbiology, she’s been awarded Distinguished Lecturer from the American Society for Microbiology and UMass, she received the Chancellor’s Medal from UMass, and she was the Harvard Forest Bullard Fellow.
Kristen loves teaching (and learning) bioinformatics and computer programming, crosswords, drawing, and hiking western Mass with her two kids and crazy dog Suki. Her lab website is here.
Kristen was one of the earliest members of MSE, contributing to a science communications piece and the paper which introduced MSE to the world!
