DRI Cytomechanics Core

Researchers at the Delaware Rehabilitation Institute will pursue a multidisciplinary, collaborative approach to address the cellular level of osteoarthritis (OA) along with prevention and treatment. The continuation of this pursuit is afforded by COBRE funding through the National Institutes of Health.


The overall goal of the proposed COBRE is to expand and develop the research capabilities and infrastructure for University of Delaware faculty to enable a multi-scale approach, addressing the problem from a cellular level (Cythomechanics Core) to a larger system’s scale focusing on muscle and joint function (Patient-Specific Modeling Core).

Voucher Program

The CytoCore Voucher Program is designed to provide use of the DRI Cytomechanics Core for faculty who need bridge or pilot funding. The program provides fee to cover the cost of using core facilities. Our goal is to help faculty between grants or just starting new projects, enabling them to collect sufficient data for competitive proposals and not loose ground on their research when grants expire.

There are no due dates for proposals. Vouchers are valid for a period of not more than one year and may be renewed. Voucher applications should be submitted to Karen Hough at khough@udel.edu and will be reviewed by Tom Buchanan, DRI Director, and/or Randy Duncan and Liyun Wang, Co-directors for the CytoCore.

All questions should be submitted to Karen Hough or Tom Buchanan (buchanan@udel.edu).
