Administrative Responsibilities

The associate dean of research, reporting to the senior associate dean, is responsible for advancing the college's research agenda and fostering scholarly excellence.

Key responsibilities include developing research strategies, assistance in garnering funding, supporting faculty development, managing grants and funding opportunities, and overseeing research infrastructure. The associate dean of research facilitates interdisciplinary collaborations, ensures regulatory compliance, and evaluates research outcomes. The role involves promoting external partnerships with funding agencies and industry, while contributing to strategic planning and reporting. They also support student research experiences through teaching and mentorship.

The position focuses on creating a collaborative research environment, helping faculty become independent scientists through extramural funding, and ensuring compliance with institutional policies and regulations.

Background

Lorne Hofseth received his Ph.D. from Simon Fraser University, British Columbia, Canada in 1996.  After completing postdocs at Michigan State University and the National Cancer Institute, he joined the faculty in the University of South Carolina College of Pharmacy in 2004. 

Dr. Hofseth is a professor, director of the Center for Colon Cancer Research, and associate dean for Research in the College of Pharmacy. He has published over 100 times, supports his program through multiple NIH awards, and has founded two companies centering around inflammation and health. Dr. Hofseth's research centers on the ability of diet, complementary and alternative medicines, and drugs to suppress low-grade tissue-specific inflammation and global, systemic inflammation as a means of preventing colorectal cancer.

The Hofseth Lab has recently focused its efforts on identifying dietary ingredients that are pro-inflammatory versus anti-inflammatory, and how we can use this information to drive policy and individual change for healthier outcomes.

Research Interests

  • Chronic inflammation
  • Colorectal cancer
  • Complementary and alternative medicines (CAMs)
  • Cancer disparities

Research Lab

Chronic inflammation is dangerous to human health. It drives many prevalent diseases in our society, including heart disease, diabetes, Alzheimer's, and cancer. Current treatment strategies that have a single target to dampen signs and symptoms of chronic inflammation are limited, and fraught with side-effects.

Our lab is dedicated to identifying novel targets and therapeutic approaches to suppressing inflammation, with minimal toxicity. One way is through the use of common complementary and alternative medicines (CAMs) that have anti-inflammatory properties. Another way is to team up with biochemists who synthesize small molecule inhibitors of specific pro-inflammatory molecules with low toxicity. Our lab also carries out clinical trials to examine the role of anti-oxidants in suppressing systemic inflammation, and improve overall health.

Recent projects have involved the used of genetically modified plants to synthesize microRNAs for chemopreventive properties.  We are interested in colon cancer disparities and are tackling this issue in collaboration with other leaders at the university, including Drs. Hebert, Berger, and Roninson.  Our bench-to-bedside approach and collaborative efforts will have far-reaching health implications on millions of people suffering from auto-immune and chronic inflammatory diseases.
