    What pesticides are in our food? 

    Is there lead in our paint, and if so, does it get into our soil too? 

    Dr. Radford’s research is centered on questions like these.  These topics are part of exposure science, in which we learn about our environment, what contaminants are in it, and how these contaminants can affect our health.  Research in exposure science uses a broad range of tools, including extractions and chromatography for pesticide analysis, and acid digestion and atomic absorption for metals analysis.


    Dr. Radford’s research on exposure has broadened to include not only, “What environmental toxicants are we exposed to?” but also, “What happens when students are exposed to active learning techniques?”  Dr. Radford is interested in how Process Oriented Guided Inquiry Learning (POGIL) and Community Engaged pedagogy helps to develop not only a student’s content knowledge, but their whole person.  Dr. Radford studies how through these engaged teaching practices, students learn skills such as leadership, civic-mindedness, critical thinking, and communication.
