Engaging Policymakers

In 2024 CASC Executive Director Kathryn Kelley presented at a Congressional briefing on the need for expanded U.S. investments in supercomputing and AI, highlighting the need for a prepared workforce and government partnership with academic institutions.

Supporting Emerging Leaders

CASC nurtures future computational research and data leaders through grants, scholarships, and mentorship, with a focus on women and underrepresented groups in STEM.

Sharing Best Practices

CASC facilitates knowledge-sharing sessions at member meetings and conferences like PEARC and SC, helping institutions enhance their capabilities.

Providing Thought Leadership

CASC participates in international conferences and discussions, shaping the future of computational research. For instance, we presented the “ABCs of Research Computing” at the EDUCAUSE conference.

Impacting Policy

Inspired by the “Missing Millions” report, our Positions Committee and workgroup on Research Ecosystem Inclusivity are working to foster a more inclusive research computing community. Our Research Data Management workgroup outlines navigation paths for research computing centers, and we regularly invite thought leaders to share insights at our biannual meetings.

Preston Smith

Executive Director, Purdue University Rosen Center for Advanced Computing

Since 2019, Preston Smith has served as executive director of Purdue’s Rosen Center for Advanced Computing (RCAC). Preston has worked in a variety of academic computing roles in 25 years at Purdue, starting his career in the Libraries, then becoming a UNIX system administrator in the Department of Physics right at the advent of Beowulf clusters and “the Grid”. Preston joined RCAC as a systems engineer for grid and distributed computing projects, where he led the systems-facing activities for Purdue’s systems on the NSF TeraGrid and XSEDE infrastructures, as well functioning as the “Chief Condor Evangelist” who managed one of the world’s largest distributed computing environments, the Purdue Condor pool.

After two years managing the R&D team for the Rosen Center, Preston moved from the systems-facing side of the business to lead the researcher-facing operation of Purdue’s community cluster systems. In this role, Preston directed the engagement, support, and outreach to researchers at the university who require high-performance computation or large-scale data storage. Under his leadership, the Rosen Center rolled out a number of initiatives to empower researchers with tools to control their own computing resources, and grew the community cluster program to increasingly greater scale and impact.

Today, Preston’s academic interest include the support of controlled research, developing the workforce in research computing and data, and studying ROI in research computing.
