Primary Research Focus
The host immune response is critical for the clearance of head and neck cancer during chemoradiotherapy (CRT). Dr. Powell's research focuses on evaluating human bio specimens to assess targets for novel therapies to augment this response during CRT.
His research also evaluates immune biomarkers in this setting, and evaluates the peripheral blood immunocyte response during standard CRT and during investigational immunotherapy combination CRT clinical studies.
His research assesses patient immune phenotype and functional response during treatment to determine peripheral blood immune response. It also investigates tumor and tumor microenvironment factors that may impact the host immune response.
Working with other labs, Dr. Powell's research uses an immune competent mouse model that harbors HPV and tumors to explore novel immuno-oncology agents combined with CRT.
His goal is to develop a biomarker-driven approach, to include novel therapeutics, into the management of advanced head and neck cancer.

The Impact of PD-1 Inhibition on Immune-Response to Chemoradiotherapy
The Powell Lab performs first-in-human clinical trials combining the PD-1 inhibitor pembrolizumab to curative intent chemo radiation in patients with squamous cell carcinoma of the head and neck.
This study aims to define the factors critical for response to therapy by evaluating peripheral blood immunocyte response and identifying important tumor-based biomarkers.
