Biography and Research Information
OverviewAI-generated summary
Ken Coffey's research explores novel therapeutic interventions for cardiovascular disease, particularly atrial fibrillation. His work has investigated the use of pulsed field electroporation for ablating ganglionated plexi, a key target in managing cardiac arrhythmias. This includes computational and pre-clinical evaluations of catheter designs for epicardial application.
Coffey also studies the cardioprotective properties of phytochemicals, such as quercetin, in mitigating cardiotoxicity induced by fescue toxicosis in lambs. His research extends to the impact of dietary protein levels on lamb performance, meat quality, and gene expression.
With 115 publications and an h-index of 17, Coffey collaborates with researchers at the Arkansas Agricultural Experiment Station, including Brittni P. Littlejohn, C.R. Looney, E.B. Kegley, and Jeremy G. Powell, with whom he has co-authored multiple publications.
