Dr. Arlos’s research is truly interdisciplinary. Her roots and skillsets are in Environmental Engineering, but she has a diversity of projects that span environmental chemistry, nanotechnology, and ecotoxicology. In 2018, she completed a diverse Ph.D. project at the University of Waterloo that involved studies on 

  1. Fate and transport modelling of emerging contaminants; 
  2. Environmental risk assessment of wastewater-derived estrogenic compounds; and 
  3. Bench-scale testing of novel titanium dioxide nanomaterials for water treatment. 

She has won numerous awards and scholarships, including the William B. Pearson Medal for creative PhD research. 

Dr. Arlos dedicates her entire career to water research. After having been awarded the ETH-Zürich and NSERC postdoctoral fellowships, she moved to Switzerland and worked on ecological effects modelling at the Swiss Federal Institute of Aquatic Science and Technology for two years (2018-2020). As an Assistant Professor in Environmental Engineering here at UAlberta, she focuses on addressing the unique water challenges that Alberta and Canada face. She particularly has a strong focus on the emerging issues associated with municipal wastewater-derived micropollutants, substances released at low concentrations into the receiving environments. Also, her work on fate/ transport and toxicokinetics modelling has benefited many aspects of ecotoxicology, and she is looking forward to contributing more to the potential remediation and regulation of trace organic contaminants in Canada.
