Research Interests

Fundamentals of phase changes, especially crystallization. Polymer science, chemistry and processing. The creation and use of novel polymers and polymer additives to improve polymer properties and processing. Energetic materials and high pressure chemistr

Research Overview

Research work started in pharmaceutical science working on psychotropic drugs before moving industries into the field of Energy and materials with Esso, Exxon, ExxonMobil and Infineum.

Expertise has been built in phase change reserach and technology, especially crystallization, oils and fuels, auto research and engineering, polymers and polymer processing, ???green??? chemistry and energetic materials.
