Area of expertise in study, research, and teaching:
Dr. Gerardo Montero, Research Assistant Professor/Co-Principal Investigator of Textile Extension & Applied Research Department at the College of Textiles, North Carolina State University. Dr. Montero has been working in the Supercritical Fluid Technology Field for the past seven years. He is a member of several scientific and professional societies, including the American Institute of Chemical Engineers (AIChE), American Chemical Society (ACS), American Association of Textile Chemists and Colorists (AATCC) and International Society for the Advancement of Supercritical Fluids (I.S.A.S.F.). Dr. Montero completed (March 1996) the work for his Ph.D. Degree and his research was focussed on the supercritical extraction soil remediation project. Dr. Montero was nominated and won the Thomas M. Weser Award at Vanderbilt University on May 31, 1996. Dr. Montero also co-authored, “Removal of Hazardous Contaminants from Soils by Supercritical Fluid Extraction,” the first-place winner in the School of Engineering’s annual research paper competition. He has approximately 10 scientific publications in the areas of petroleum, chemical and textile engineering and has materially participated in 4 funded research projects with total direct costs of $ 490,000. In addition to his research effort obtaining both his M.Sc. and Ph.D. degrees, Dr. Montero has spent five years in the petroleum industry as a chemical engineer involved with engineering operation and research and development. In May 1996, Dr. Montero commenced work as a research associate and then later as a Visiting Assistant Professor in the College of Textiles at NCSU. Recently, Dr. Montero become as a Research Assistant Professor at NCSU and his primary duties involve working with the Research and Development on Supercritical Fluid Technology in the Textile Processing Project and the CO2 dyeing Consortium.
