Mark Williamson Research
Welcome to the research page for Dr. Mark Williamson.
Dr. Mark Williamson is a research assistant professor in the Department of Population Health, statistician and core coordinator for the DaCCoTA, and the director of the ROAR Radon Chamber. His research is focused on 5 areas.
- Experimental Radon Test Chamber Studies
- Statistical Designs for Epidemiology
- Omics, Microbiomes, and Interpretation
- Epidemiological Taxonomy
- Technological Applications in Epidemiology
Radon Test Chamber
The UND Experimental Radon Chamber is being designed for radon exposure experiments on cell and animal models. The chamber will consist of an air-circulation system that carries radon gas from radioactive sources to enclosed cages and then vents to the outside via a fume hood. It will be built and operated to fulfill the safety and ethics guidelines from both the Office of Safety (radiation, biology, etc.) and via established experimental IACUCs. In short, the radon chamber will be set up to provide radon exposure environments for a variety of in vitro and in vivo experiments. The specific setup will depend on the specific experiment, but the general procedure is a closed environment with an adjustable concentration of radon gas. ETC.
The radon chamber is currently under development. Check back later on the following items.
- Information on submitting a project to the Radon Test Chamber
- Virtual tour of the Radon Test Chamber
Statistical Designs for Epidemiology
