Yuxin Wang, Ph.D.

B.S., Environmental Science, Sun Yat-sen University, 2010
M.S., Civil and Environmental Engineering, Carnegie Mellon University, 2011
Ph.D., Civil and Environmental Engineering, Carnegie Mellon University, 2014
 
Research Interests: I am interested in environmental risk assessment and water quality. My interest extends not only to water and wastewater treatment, but also to the fate and transport of organic chemicals, like pesticides and pharmaceuticals, in the environment. I am also interested in and have worked on issues at the food, energy, water nexus, and ways to find sustainable solutions for emerging water challenges. 
 
Other Interests: Travel, impressionist oil painting, and cooking.

Ph.D., Environmental Chemistry, ETH Zurich, 2017
 
Research Interests: I am fascinated by how microorganisms use extracellular enzymes to transform large molecules outside a cell. My PhD work helped to better understand the enzymatic hydrolysis and the microbial utilization of synthetic polymers in agricultural soils. The focus of my current research is to decipher the role of extracellular hydrolases in the transformation of micropollutants during biological wastewater treatment.

Thesis Title: Removal of micropollutants in biofilters: Hydrodynamic effects on biotransformation rates
Dissertation Title: Environmental monitoring for micropollutants using high-resolution mass spectrometry and data-driven methods
 
Research Interests: I am interested in improving our environmental monitoring capabilities for organic micropollutants (e.g. pharmaceuticals, pesticides, and industrial chemicals). Today, traditional monitoring practices screen relatively few samples for relatively few micropollutants, which can severely under-represent the true chemical contamination. My research focuses on developing comprehensive micropollutant characterization strategies (i.e. sampling schemes, analytical methods, and data processing methods) to better understand micropollutant sources, fate, and transport in surface waters.
