Areas of Expertise

Dominik Barz has academic and professional experience in areas encompassing both Mechanical and Chemical Engineering subjects. He worked as a laboratory engineer in a Mercedes Benz endowed fuel cells lab for five years and gained much experience in Electrochemical Engineering. Thereafter, his interests have been focused on the development of Lab-on-a-Chip Technologies including research on Microfluidics, Transport Mechanisms, and Surface & Interface Phenomena. The research consists, on one hand, of mathematical modeling and numerical simulations. On the other hand, his research always includes experiments to verify the theoretical models and assumptions that have been developed.

Research Opportunities For Graduate Students

Master's Project: Surfactant-Induced Interface Phenomena in Nonpolar Liquids

Supervisors: Professors D. Barz and C. Escobedo, Chemical Engineering, Queen's U.

We are looking for a highly-motivated domestic Master’s student with the ability to work independently for research projects in the area of surfactants. An important feature of surfactants is that they can be used generate electrical charges in nonpolar liquids which can hardly be achieved otherwise. These attributes are used for the safe transport of oil in pipelines as well as modern electronic display technologies. In the proposed research, we aim to explore the charge generation mechanisms in surfactant/nonpolar liquid mixtures. This research project is suitable for a student with affinity to experimental work. Experience and skills in wet chemistry, interface science, electrochemistry, analytics and measurement of electrical quantities are an asset.

Qualified applicants should have a  Bachelor degree in Chemical Engineering, Chemistry or another related discipline. Interested candidates with demonstrated excellence in academics and/or with relevant research experience should send their CV, recent academic history, and contact information for two professional references to Dr. Barz. Anticipated starting date is May or September 2017.

Please understand that we will only contact those applicants who will be considered for an interview.
