Erica Hartmann's Bio:
Dr. Erica Marie Hartmann is an environmental microbiologist
interested in the interaction between human-made chemicals and
microbes. Her career began at the Johns Hopkins Bloomberg School of
Public Health, where she worked on mass spectrometry-based methods
for detecting microbial enzymes necessary for bioremediation. She
then moved to Arizona State University where she was the first
graduate of the interdisciplinary Biological Design PhD program.
She when to France on a Fulbright, studying microbes that degrade
carcinogenic pollutants at the Commission for Atomic Energy. She
began leading studies antimicrobial chemicals and microbes found in
indoor dust at the Biology and the Built Environment Center at the
University of Oregon and is currently continuing that work as an
assistant professor at Northwestern University.
Assistant professor of civil and environmental engineering at
Northwestern University, Erica Maria Hartmann, joins the show to
discuss the interesting reactions that occur between antimicrobial
chemicals and antimicrobial resistance.
Tune in to discover the following:
Antibiotic resistance is one of the biggest global health threats right now, and according to Hartmann, the cleaning products we use, the way we clean, and the assumptions we make about microbes are not helping. Much of her work revolves around trying to understand how the use of specific chemicals impacts the microbes in indoor environments.
She explains that while most people operate under the assumption that all microbes are bad, the vast majority of microbes are neutral if not good; ironically, it is the chemicals we use and the way in which we use them that can sometimes be more detrimental to our health, and actually foster the development of antimicrobial resistance.
The main goal of Hartmann’s work is to identify the specific impacts of specific cleaning products on different microbial communities, and thereby be able to determine whether the appropriate cleaning agent is being used in the correct way. For example, depending on the specific microbe that's being targeted by a cleaning agent, soap and water might be all that’s necessary, as opposed to a harsh chemical such as bleach.
Hartmann is a wealth of knowledge on environmental microbiology
and these other incredibly relevant topics, so press play to hear
