The main goal of this project is to detect longitudinal changes in physiological biomarkers in vivo using fiber-based optical spectroscopy techniques. The optical endpoints will be optimized to serve as early predictors of treatment response in solid head and neck tumors that are undergoing radiation and/or chemotherapy. Profs. Nimmi Ramanujam and Mark Dewhirst serve as mentors on the project.

While many outstanding applications were received, the awards committee felt that Dr. Yu's proposal was one that best explained how this award would enhance his professional growth. A poster announcing the award winners will be displayed at the Spring Fling this Friday, May 9, from 4-6 pm at the French Science Center. Dr. Yu will receive $1,000 for his research activities.

2007:

  • The Carolinas Photonics Consortium (CPC) has selected BME post doctoral researcher Quincy Brown to receive $10,000 in seed funding for Endls Optics, the Duke spinoff company developing technology to measure the removal of breast tumors during breast conserving surgery.  Associate BME Professor Nimmi Ramanujam leads the project. Brown received a Duke Cancer Center Young Investigator Award earlier this year.
  • In September of this year, The NIH awarded BME post doctoral researcher Bing Yu and associate BME professor Nimmi Ramanujam with a phase I Small Business Technology Transfer (STTR) grant. This will be a collaborative project between Endls Optics and Duke University. The research will focus on technology development and optical surveillance of surgical tumor margins in patients undergoing breast conserving surgery for cancer.

These probes will provide increased depth-sensitivity to epithelial tissues, thereby increasing the sensitivity and specificity of optically based diagnosis of epithelial pre-cancers.
  • J. Quincy Brown, a postdoctoral associate working for Ramanujam, has been awarded an NIH NRSA postdoctoral fellowship from the National Cancer Institute for his project entitled "Multi-label molecular FLIM of breast cancer".
