Dr. William Acree is currently Professor of Chemistry at the University of North Texas. He has published more than 560 scientific research articles, plus five books, six book chapters and four encyclopedia articles. He serves as a member on the Editorial Advisory Boards of eight journals and has been a manuscript reviewer for over 60 leading international journals. Professor Acree’s research interests involve developing quantitative structure-property relationships and linear free energy relationships to describe partitioning processes of chemical, environmental and pharmaceutical importance. To date he has derived expressions for predicting the solubility of drug molecules in water and in more than 70 organic solvents of varying polarity, for predicting the distribution of organic compounds and drugs between select rat (and human) tissue samples and blood, for predicting the toxicity of organic compounds to several aquatic organisms, and for predicting the solute partitioning between water and numerous organic solvents.
