Research and Teaching Interests

(I) Machine Learning for Chemical Analysis

     Research in artificial intelligence (AI) has led to the development of many machine learning algorithms for image recognition. Their ability to analyze large amounts of data and extract meaningful hidden structures is unprecedented. My research interest focuses on combining chemical analytical tools and machine learning for qualitative and quantitative chemical analysis.

(II) Super-resolution Microscopy

     We develop high-resolution optical microscopes to investigate biological questions. The resolution of optical microscopy has been limited to ~ 200 nm because of the diffraction limit. Recent developments in super-resolution microscopy has enabled scientists to resolve features as small as 10 nm and visualize cellular structures in unprecedented detail. Our current research is focused on virus-host interactions.

(III)  Surface Properties of Water and Ice Nucleation

     Water has a relatively simple molecular structure, but the interface of water is a very complex system. We study water interfaces relevant to environmental and industrial applications using nonlinear optical spectroscopy.

(IV) Petroleum Surface Chemistry

     Canada’s oil sands reserves, which are estimated at 175 billion barrels, place Canada second in the world ranking of crude oil reserves. However, the large amount of water used in current bitumen extraction processes is a great concern, particularly as the industry is expected to grow over the next 20 years. Our research objective is to understand the competition adsorption of solvents, water, and bitumen on mineral materials to provide molecular-level information for developing a more environment-friendly extraction process. This research project has been funded by the Institute for Oil Sands Innovation located in the University of Alberta.
