Substrate Services Core Research Support

Substrate Services Core Research Support logo


The Substrate Services Core Research Support (SSCRS) was developed in 2014 to serve as a centralized processing core and storehouse for research samples for large clinical, consortium-based collaborations and for basic, discovery science. We meet the increasing need for high-quality, well-characterized biological samples to be utilized by researchers working in clinical and translational research, ultimately enhancing the diagnosis and treatment of future patients.

The SSCRSS produces quality translational science through validated, standardized methodology and protocols that are implemented across studies, reducing non-relevant variability in results. To support this standardization, the core is in compliance with internationally recognized Good Clinical Laboratory Practice (GCLP) and 21 CFR Part 11. Reproducibility across supported research is achieved through continued monitoring of the quality system by the Quality Assurance for Duke Vaccine Immunogenicity Programs (QADVIP), an independent quality assurance unit.

Jennifer Cheeseman-Janes, MS, Senior Director

Jennifer has over 14 years of experience in the scientific and technical management of clinical, basic science, and translational research, and has extensive knowledge in proposal development, financial planning, project management, regulatory and institutional compliance, and improvement of organizational efficiency within the academic setting at both divisional and departmental levels. She has spent the last 3 years at Duke University developing research support via core services, improving and developing core infrastructure, improving long-term strategic planning and promotion of collaborative and transformative research with collaborators both internally and externally. She serves as the biobanking lead of two Department of Defense biobanking consortiums in collaboration with Duke University, the Department of Surgery, and the Surgical Critical Care Initiative (SC2i), supporting precision medicine in wounded warriors and the Vascular Composite Allograft Collaborative Initiative (VCAci), supporting translational research in hand transplantation. Prior to joining Duke, Jennifer served as the Director of the Emory University Transplant Center Biorepository where she developed and implemented an Integrated Research Support Service that encompassed study development around sample and clinical data collection and linking, financial planning, project management, clinical regulatory and institutional compliance, improving on organizational efficiency within the academic setting at both divisional and departmental levels. Jennifer earned her BS and MS from the University of Florida and is currently completing her MBA at North Carolina State University.

Mary-Beth Joshi, MPH, Assistant Director

Mary-Beth has spent more than 20 years directing complex, multi-faceted, multi-institutional, and multi-disciplinary clinical, translational, and basic science as well as clinical outcomes research projects in oncology. For more than two decades she has been instrumental in the development, implementation, and management of biospecimen and clinical data repositories and associated experimental data with the ability to transform working hypotheses into fully executable projects with defined benchmarks, goals, and measurable objectives. She has extensive experience in operations management effectively streamlining and optimizing project processes and resources to meet defined benchmarks and timelines. Mary-Beth earned her BS in Biology and Sports Medicine from Wingate College and her MPH in Public Policy from AT Still University.
