Prospective Student Opportunities
Ph.D. research assistant positions are available. Students with interest in the environmental impacts or applications of colloids or nanomaterials, environmental surface chemistry, organic geochemistry, and environmental analytical chemistry are encouraged to apply. Dr. Louie’s projects lie at the interface of these research areas. Please contact Dr. Louie with your CV, including GPA and GRE scores (and TOEFL scores, if applicable). Visiting scholars and undergraduate and graduate students are also encouraged to contact Dr. Louie regarding research opportunities.
Awards & Honors:
Our group’s research contributes to the fields of environmental nanotechnology and environmental fate and transport of nanoparticles, colloids, and emerging contaminants. We are evaluating and improving nanotechnologies for advanced wastewater treatment applications. We are also assessing the environmental health and safety implications of nanomaterials, including the inherent risks of the nanomaterial itself and the role of nanomaterials as delivery technologies to either alleviate or exacerbate the risks of other emerging contaminants.
Our research is especially focused on surface interactions of particles and the degradation of polymeric coatings or particles in environmental systems, such as wastewater treatment plants or natural waters. Specific research topics include adsorption of natural organic matter and biomolecules onto particle surfaces, experimental approaches to characterize and predict the properties of these adsorbed layers, the effects of surface coatings on the behavior of the particles, and the extent and rate of polymer degradation.
