Research

Major Responsibilities/ Research Interests 

My research focuses on emerging processing technologies and the use of near-critical and supercritical water and carbon dioxide to treat biomass and agricultural materials for use in nutraceutical, food and industrial applications; mathematical modeling and computer simulations of unit operations. Another aspect of my research includes the use of High Pressure Processing and High Pressure Processing assisted by Temperature to treat crops and food products. 

Crops that are currently under study in my research team include potato, flax, wheat, triticale, lentils and peas. Among crops previously studied are barley, canola, coffee and cocoa beans, guarana seeds, carrots, tomatoes, Echinacea roots and tea leaves. Unit operations commonly used by my team are extraction, fractionation, adsorption, reaction, and encapsulation. I maintain fruitful collaborations with researchers from renowned centers and universities in Japan, Germany, The Netherlands and Brazil. Thus, I provide an exciting research program in the area of high pressure processing, nanotechnology and supercritical water technology.

Teaching

Graduate/PDF Career Opportunities

Graduate students and PDFs with interest in supercritical fluid technology are encouraged to apply. Ideal students and researchers will have a degree in food engineering or chemical engineering, but students from other disciplines with interest in supercritical water technology, nanoencapsulation or high pressure processing will also be considered.
