Dr. Kim’s primary research interests include the development of polymeric materials for controlled release drug delivery systems and the modulation of drug release kinetics.  Surface area modulated systems have been extensively developed to overcome a limitation of common dosage form geometry.  To minimize and eliminate the effect of drug diffusion from matrix controlled systems, a change of drug moiety has been evaluated for linear extended release.  A new process to produce biodegradable micro-particles for the delivery of peptides is under development and its operating variables are investigated for a large scale production.  Non-matrix controlled transdermal delivery systems are investigated using sol-gel and thermal gelation processes.  His innovative controlled release technologies at Temple University and UAMS eventually led to fruitful results and reached a major licensing agreement with a pharmaceutical company (the largest licensing agreement in Temple University technology transfer history at that time) and a foreign pharmaceutical company, respectively.
