Dr. Karen C. Dannemiller
I am an Associate Professor at Ohio State University with a joint appointment in Civil, Environmental, and Geodetic Engineering and Environmental Health Sciences. I also have a courtesy appointment in Microbiology and am a core faculty member in the Sustainability Institute. My interdisciplinary research integrates engineering with microbiology and addresses emerging health challenges and environmental concerns using -omics approaches. Within the indoor environment, we are simultaneously exposed to thousands of chemicals and microorganisms which compose our indoor exposome. Broadly, the goal of my work is to understand these exposures, their sources, and their impact on human health while fostering student engagement. My unique background combines training in both engineering and public health to tackle difficult questions, particularly with regards to exposures in the built environment, where we spend 90% of our time.
Prior to my current position, I graduated with honors in Chemical and Biochemical Engineering from Brown University and earned my M.S., M.Phil, and Ph.D. at Yale University in Chemical and Environmental Engineering. During this time, I completed an internship at the California Department of Public Health in the Indoor Air Quality Program. I was also a Microbiology of the Built Environment Postdoctoral Associate at Yale University. My work improved our understanding of human exposures linked to childhood asthma development and severity. My research also elucidated resident microbial populations and fundamental transport processes occurring in homes. My current research is on microbial activity in house dust, indoor exposures, and asthma.
In addition to a fundamental background in engineering and quantitative sciences, my skill set in microbiology includes phylogenetics, metagenomics, and transcriptomics and allows for exploration of microbial communities and biological processes. I have extensive experience with next-generation DNA sequencing of fungi and bacteria and using this data I have also addressed relevant challenges bioinformatics, including software development, and in statistics, to demonstrate complex associations with human health outcomes.
I teach classes in Risk Assessment, Probability and Statistics for Engineers, and another class titled Engineering Design for Environmental Health.
I was awarded the Denman Distinguished Research Mentor Award in 2017 and the IMR Early Career Innovator of the Year in 2019. In 2020 I also received a five-year Faculty Early Career Development (CAREER) award from the National Science Foundation, the Lumley Engineering Research Award, and the Buckeye Engineering Women in Executive Leadership (BEWEL) Leadership in Innovation Award.
