Dr. Christopher Wellen (PI)

Dr. Wellen is an Assistant Professor with the Department of Geography and Environmental Studies at Ryerson University. Chris is an environmental scientist whose work focuses on the intersection of hydrology and biogeochemistry in human dominated environments. His work has focused on agricultural, urban, and surface mined areas, but the essential questions are typically: How do natural processes and human modifications to a watershed interact to transport water and materials? What are the effects on instream and downstream ecosystems, and how are these effects likely to change in the future?

Dr. Wellen received a PhD from the University of Toronto in 2013 focusing on comparing the phosphorus export dynamics of urban and agricultural watersheds. His postdoctoral work at McMaster University focused on the role of surface mining in affecting selenium release from watersheds. His subsequent postdoctoral work at the University of Waterloo focused on improving the numerical analysis of watershed data from agricultural systems. Dr. Wellen received an MSc in GIScience from McGill University and a BSc in Water Environments and Ecosystems from McGill University’s School of the Environment.

​Dr. Cody Ross
​Post-Doctoral Fellow, co-supervised with Claire Oswald
​
Cody joined the group in January 2021 following a PhD at the University of Manitoba. His work focuses on the development of surrogate models for predicting concentrations of critical water quality parameters. More broadly this work aims to leverage available sensor technologies to better understand high-frequency water quality dynamics and guide future monitoring programs. Fun fact: Cody enjoys cycling and completed a solo, unsupported Winnipeg – California round-trip in 2012.

Dr. Kelly Biagi​
​Post-Doctoral Fellow

Kelly is working to determine the landscape drivers behind nutrient loading dynamics in several headwater streams in Southern Ontario. Kelly joined the team in April 2021 after completing her PhD at McMaster University which focussed on constructed wetland hydrology and hydrochemistry in the Athabasca oil sands region. Kelly loves spending time outside, camping and hiking but also enjoys spending time at home playing board games and trying to improve her green thumb.

​Bhaswati Mazumder
PhD Student
​
​Bhaswati joined the team after completing MSA at Ryerson. Her research focuses on chloride pathways in watersheds due to road salt applications. Current research interests include legacy chloride due to long term road salting in urban and urbanizing catchments, chloride retention in soil, and water quality modelling.

​Larissa Gospodyn
Research Assistant
​
​Larissa joined the lab in May 2018 as a research assistant. She began her MASc degree in the following fall and completed it in August 2020. Larissa's research focuses on isotope hydrology in agricultural catchments and other research interests include water quality and catchment hydrology. ​
