- Dr. Stockwell strongly believes in the power of active learning with an emphasis on self-guided discovery. Because of this, she incorporates various aspects of team-based learning into all of her courses. In doing so, students learn to work collaboratively in the application of course concepts to solve “real world” inspired problems.
- Dr. Stockwell supports inquiry-based learning at the K-12 level through a variety of ongoing activities:
- Science education outreach to Page County Middle School: Activities include leading 7th grade biology students in inquiry-based microbiology experiments and hosting 8th graders for a day of hands-on science activities at JMU.
- Visiting instructor for the annual Shenandoah Biotechnology Symposium hosted by Eastern Mennonite High School.
- Judge for the Biochemistry and Microbiology Divisions of the Shenandoah Valley Regional Science Fair and the Virginia Junior Science and Humanities Symposium
- Together with Dr. Louise Temple (JMU, ISAT), Dr. Stockwell leads an NSF-CCLI funded summer workshop for regional small four-year undergraduate colleges community college, and high school faculty members. Focused on the use of microarray technology in teaching fundamentals of molecular biology and discovery-based science, this week-long workshop involves performing and analyzing the result of microarray experiments, developing teaching and assessment materials, and creating important relationships between regional faculty members. More information about this workshop and the JMU Microarray Project as a whole can be found at: http://microarray.cisat.jmu.edu/
- Visiting faculty for the inaugural 2011 Citizen Science Program at Bard College, NY
- JMU Honors Faculty Fellow; College of Integrated Science and Engineering (2011-present)
- ISAT Honors Liaison (2012-present)
Scholarly Interests/Research Topics
- Dr. Stockwell pursues her interest in host-bacterial interactions through two main avenues of research—Bordetella avium/turkey pathogenicity and Bradyrhizobium japonicum/soybean symbiosis. In understanding how microbes attach, adapt, and impact their eukaryotic hosts (for better or worse), much can be learned about pathogenesis and symbiosis as a whole. This information can be ultimately used to block or transform harmful host relationships and enhance beneficial ones.
Ongoing Research Projects
- Work to understand the molecular and genetic requirements for B. avium pathogenicity is done in close collaboration with Dr. Louise Temple (JMU, ISAT). B. avium, in the genus of bacterial pathogens that cause diseases such as whooping cough and kennel cough in various mammals, is an economically important pathogen of birds. Together with undergraduate researchers (approximately 7-10 each semester), Dr. Stockwell and Temple work to identify and characterize various B. avium genes involved in turkey tracheal attachment and host cell toxicity. Such studies are guiding the development of B. avium live-attenuated vaccines for use in the poultry industry.
- Stephanie Stockwell maintains a research program involving the molecular characterization of the B. japonicum/soybean symbiosis. As an extension of work done in the laboratory of Mary Lou Guerinot, Ph. D. (Dartmouth College), this program is focused on the genetic and molecular characterization of the symbiotic interaction between Gram negative soil bacterium, Bradyrhizobium japonicum, and it leguminous host plant, soybean. During the symbiosis, the bacteria fix atmospheric nitrogen for use by the plant, thereby decreasing the need for supplemental nitrogen fertilizers in large-scale agriculture. Work in the Stockwell lab includes creating mutant B. japonicum strains lacking iron uptake and signal transduction genes, critical for the adaptation to and survival within the host environment. These mutant strains serve as tools for identifying in planta specific signaling networks required for a functional symbiosis. The role of the dual-function ferrichrome uptake receptor, FegA, is of particular interest in both iron uptake and symbiosis.
