Dr. Hayes is the author or co-author of more than 185 reports, 24 chapters, and 177 abstracts, the following of which
are the most recent. He is co-inventor on 9 patents, and several discoveries in his lab currently have marketplace
applications, eg. discovery of a taurine requirement for cats and infant primates led to taurine inclusion in all cat foods
and human infant formulas. ALPO cat food originated from research in his lab, and currently most supermarkets in the
USA carry SMART BALANCE, a trans fat-free margarine designed to improve the LDL/HDL ratio.
