Dr. Builes main research interests are the applications of molecular modeling to solve and/or obtain a better insight of industrial problems. The scope of his research is mainly focused on applications of these atomistic simulation to separation processes and catalysis. Through the use of computer simulations it is possible to observe and understand materials and processes on a molecular scale. Atomistic simulations can be applied for different materials, such as: meso- and nano-materials tailor-made for specific applications, well-structured mesoporous materials and amorphous materials.
