The Journal of Computer-Aided Molecular Design provides a form for disseminating information on both the theory and the application of computer-based methods in the analysis and design of molecules. The scope of the journal encompasses papers which report new and original research and applications in the following areas: theoretical chemistry computational chemistry computer and molecular graphics molecular modeling protein engineering drug design expert systems general structure-property relationships molecular dynamics chemical database development and usage. Contributions on computer-aided molecular modeling studies in pharmaceutical polymer materials and surface sciences as well as other molecular-based disciplines are particularly welcome.
