Biography and Research Information
OverviewAI-generated summary
Luke R. Howard's research focuses on the chemical composition and health benefits of berries and other plant-based compounds. His work investigates the phytochemical content of various berries, including blueberries, blackberries, and black raspberries, and their potential effects on cell models of inflammation and oxidative stress. Howard has also explored the volatile compounds in berries, their biosynthesis, and their impact on bioavailability and health. His research extends to agricultural applications, including a role as Co-PI on an NSF grant focused on creating a workforce pipeline for agriculture drone operators and remote sensing technicians.
His publications examine the antiproliferative effects of berry extracts on cancer cells, the influence of harvest time and fruit firmness on berry quality attributes, and the polyphenolic profiles of wild berries. Howard also investigates the impact of agricultural practices, such as sulfite levels and yeast inoculations, on fermentation processes in grapes. He leads a research group and collaborates with multiple researchers at the University of Arkansas at Fayetteville, including Renee T. Threlfall, Sun‐Ok Lee, John R. Clark, and Margaret Worthington.
