Meet our talented team

“In the Inukshuk statue, each stone is a separate entity, each individual with its own significance; yet each is also supporting and being supported by the stones above and below it. It’s strength lies in its unity; its significance comes from its meaning as a whole.”
Dedication. Expertise. Passion.
Principal Investigator
Dr. Sara Beck joined the Department of Civil Engineering of the University of British Columbia as an Assistant Professor in April of 2021 with a research group focused on understanding and preventing pathogen transmission at the confluence of public health, water quality, and innovative water treatment solutions. She and her team use microbiology tools to improve water treatment and reuse processes and bridge the gap between knowledge and practice. Before joining UBC, Dr. Beck evaluated cost-effective decentralized water reuse technologies at the Asian Institute of Technology near Bangkok, Thailand, and at Eawag, the Swiss Federal Institute of Aquatic Science and Technology near Zurich, Switzerland.
Dr. Beck earned her Ph.D. in Environmental Engineering from the University of Colorado Boulder in 2015. Her doctoral dissertation on Wavelength-Specific Effects of UV Light on Microorganisms and Viruses for Improving Water Disinfection received the Outstanding Doctoral Dissertation award from the Association of Environmental Engineering and Science Professors (AEESP) in 2016. She received an M.S. in Environmental Engineering from the Georgia Institute of Technology and a B.S. / B.A. in Aerospace Engineering / Studio Art from the University of Colorado Boulder. She supported the Space Shuttle and International Space Station programs in her first career as a NASA flight controller.

Undergrad Co-op Student - 2023
Harkirat is studying biochemistry with a focus on neuroscience. He has a variety of research experiences ranging from cognitive psychology to biological fieldwork. His first paper was published in his first year at UBC in which Harkirat explored the air permeability of face masks using fluid dynamics (https://dx.doi.org/10.14288/1.0398551). At the Beck Lab, Harkirat's focus is on quantifying the viral load before and after disinfection via different methods.
