Synergistic Activities:

  • Over the last two years, I have started a new STEM Scholars Center on campus aimed to increase the recruitment and retentions of underrepresented and underserved student populations. This program has included outreach to local area high schools and the creation of an equipment rental program for high school chemistry classes to be able to engage students in hands-on laboratory activities.
  • For the last five years, I have participated as a Vertical Leader in an NSF Advance Grant entitled, Advancing the careers of women in STEM at predominantly undergraduate institutions. The PI of this grant is Joanne Smieja at Gonzaga University. Participation in this program has allowed me to develop new leadership skills and enhance my undergraduate teaching skills, especially in the development of innovative ways to include undergraduate research in the classroom.
  • I have developed of a new Faculty-Led Study Abroad Program in the Applications of Traditional Chinese Medicine (TCM). This program has successfully brought students to China in the summers of 2013 and 2015 to study the therapeutics of TCM.  Two undergraduate students from this program are currently conducting natural products research within my laboratory.
  • I have developed the Medicinal Chemistry and Pharmacology Emphasis Program in Chemistry at Western Oregon University. This program has helped to triple our enrolment of Undergraduate Chemistry Majors at WOU over the last three years and provides new opportunities for undergraduate students to conduct research within our department.
  • Over the last 9 years, I have trained a total of 26 undergraduate students within my laboratory.
