Personal Statement

As University of Hawaiʻi Cancer Center Director, I oversee all research activities and direct operational activities of the center, including allocation of space, appointment of faculty, and management of budgets and finances. I serve as the principal investigator for the P30 Cancer Center Support Grant and lead strategic planning initiatives as they relate to the Cancer Center.

Research Focus

1. Health services research in oncology
Quality-focused research has included description of a novel compensation model for clinical oncologists, development of a new tool to monitor adherence to evidence-based guidelines and proposal of new paradigm for consideration of healthcare quality. Additional research studies have focused on patient-reported outcomes, and specifically on the influence of demographic and structural factors that non-variably affect patient satisfaction scores, a critical element in value-based reimbursement models. These studies advance the field of health services research both for oncology and for healthcare overall.

2. Wnt signaling in colon cancer
We were the first to describe the selective expression of LEF1 in colon cancer and more recently described a novel Wnt-dependent pathway that controls the distribution of specific TCF isoforms. We have also identified a novel Wnt-stimulating ligand, Norrin that may control angiogenesis in the colon tumor microenvironment. These studies have advanced the understanding of Wnt signaling as a highly regulated signaling pathway that not only promotes carcinogenesis but also influences tumor invasion and metastases.

3. Role and mechanisms of action of natural products for cancer treatment and prevention
Laboratory studies demonstrated that resveratrol suppresses Wnt signaling in vitro. This led to a clinical trial of resveratrol, a dietary study of grape consumption that demonstrated that the primary effects were on normal mucosa, suggesting that the principal effectiveness may be in cancer prevention, rather than cancer treatment. Biological endpoints confirmed the activity of a resveratrol-containing whole food modulates Wnt signaling in patients, particularly those at increased risk for the development of colon cancer. This line of investigation has significantly contributed to our understanding of the role of natural products for cancer treatment and prevention, particularly with respect to their suppressive activity on Wnt signaling.

"University of Hawaiʻi Cancer Center CCSG"
The Cancer Center Support Grant (CCSG) is the foundational infrastructure that supports two Cancer Center programs, Cancer Biology and Population Sciences in the Pacific, and five shared resources including Analytical Biochemistry, Biostatistics, Genomics and Bioinformatics, Nutrition Support, and Metabolomics. The CCSG also supports translational and clinical research services involving an extensive network of oncology care sites across the State. The mission of the University of Hawaiʻi Cancer Center is to reduce the burden of cancer through research, education, patient care and community outreach with an emphasis on the unique ethnic, cultural and environmental characteristics of Hawaiʻi and the Pacific. Because of the unique population in Hawaiʻi, UH Cancer Center investigators examine questions that are not easily addressed within the continental states with impact on patient care on a local, national, and global level. Moreover, UH Cancer Center directs cancer prevention and control research activities across the Pacific.
I assumed the position as University of Hawaiʻi Cancer Center Director in October, 2016 and have oversight over all research and operational components.
