Daryl J Murry is a Professor of Pharmacy Practice and Science at the University of Nebraska Medical Center, Omaha, NE, USA. He holds a B.Sc. in Pharmacy and a Pharm.D. from the University of Iowa. His research focuses on identifying sources of variability for drug response, including pharmacokinetic and pharmacogentic determinants of drug clearance. In addition to identifying the pharmacokinetic variability, he has worked to identify the sources of this variability in children and develop strategies in individualized drug therapy based on pharmacokinetic/pharmacodynamic variability. More recently his group has included pharmacogenomics in our efforts to further individualize cancer drug therapy.
