    About Dr. Samantha Radford


    • B.S. in Chemistry, Berry College
    • Ph. D. in Chemistry, Emory University


    Dr. Samantha Radford is native to a Georgia, where she lived her whole life before moving to Pennsylvania to build a life and career at Saint Francis University.  Dr. Radford's doctoral work took place at Emory University in Atlanta, GA.  During graduate school, she studied the degradation of insecticides in food and how this topic affects the quantification of people's pesticide exposure.  While Dr. Radford's Ph.D. is in chemistry, she performed her research in the Rollins School of Public Health at Emory with colleagues and mentors with experience with the Environmental Protection Agency (EPA) and the Centers for Disease Control and Prevention (CDC).  Therefore, Dr. Radford has a unique interest in the intersection of chemistry and public health.  


    Since moving to Pennsylvania, Dr. Radford has also become interested in more local exposure science problems, such as children's lead exposure through paint, water, and soil.  Dr. Radford is also interested in acid mine drainage research, another concern specific to this region.  Dr. Radford lives in Duncansville, PA with her husband and three children.

    Research & Teaching

    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.
