As the Associate Director I work closely with the SERC team and our partners at institutions across the country to improve the undergraduate experience for students of all backgrounds in STEM and related fields. My work is primarily in project management, professional development and dissemination, community visioning and bringing science into broader use. I have become increasingly involved with SERC's research efforts and planning in next steps for increasing the reach of work from projects such as the InTeGrate STEP center.

Example Projects

Go to
The EDDIE Earth and Ecosystems project continues the work done in earlier Environmental Data-Driven Inquiry and Exploration projects working with undergraduate faculty to create teaching modules that expand the range of environmental data and approaches to working with data that students use in environmental science, limnology, ecology, hydrology and geology courses. The project is developing and validating a much larger suite of curricular modules to 1) improve student quantitative reasoning, 2) develop a community of practice to engage faculty members and foster a pedagogical orientation that favors open inquiry with large datasets and, 3) determine what mechanisms contribute to shifts in an instructor's pedagogical orientation.

Go to
The InTeGrate Implementation program is an example of a project with a significant project management component that is indicative of SERC practices. This is a program within the InTeGrate STEP center focused on using and adapting curricular material, developed and tested by InTeGrate author teams, to new contexts. We solicit proposals from, and then support, teams of faculty members using InTeGrate modules or approaches in improving cross-disciplinary learning, broadening access and workforce preparation in undergraduate students. We are supporting faculty members building interdisciplinary programs, redesigning majors and minors, bridging or developing pathways for two-year/four-year school transitions and using online or blended delivery mechanisms, and helping them evaluate the outcomes of their projects.

Go to
In 2013 the Association of Public and Land-grant Universities launched a national discussion on university-based STEM Education Centers. With university partners, and spearheaded by APLU, this project has grown into an effort to build a network of STEM centers to foster communication and interaction among STEM Education Centers to facilitate synergy and increase capacity among centers. I was involved in planning the second national meeting of this group and now am a member of the project steering committee.

Go to
The LSAMP IINSPIRE program was formed as a consortium of 16 colleges and universities in the Midwest, and primarily Iowa, to broaden the participation of underrepresented minorities in science, technology, engineering, and mathematics (STEM) education. They set out to double the number of graduates from underrepresented groups in STEM disciplines across their schools. SERC has been working with LSAMP, and particularly members at Grinnell College, to host workshops for IINSPIRE faculty on using evidence-based practices in their courses. In 2014 I worked with IINSPIRE members on workshops focused on increasing authentic research experiences for undergraduates, especially at two-year schools.
