Email: maryam.shahmansoori@ubc.ca / LinkedIn

Maryam joined Dr. Mohseni’s research group as a part of her Ph.D. program in Chemical Engineering at Sharif University of Technology, Iran. Her doctoral research focused on the synthesis of green bio-composites as promising adsorbents and photocatalysts for AOPs applications. She started working as a postdoctoral research fellow at the University of British Columbia after completing her Ph.D. Since then, Maryam has been involved in managing, supervising and participating in multiple projects related to providing and developing innovative and effective methods for measuring atmospheric ionic deposition and also water treatments with UV/VUV AOPs and Ion Exchange resins. She has also dedicated a part of her research to removing emerging contaminants, such as per- and polyfluoroalkyl substances, from water with novel techniques.

Maryam is looking forward to turning her research and innovations into practical solutions that enhance the quality of life in communities, drawing on over a decade of academic and industrial experience.

Rachel Boyer

Email: rachel.boyer@ubc.ca / LinkedIn

In her current role, Rachel works with Indigenous communities in British Columbia to understand water security risks and climate vulnerabilities, and co-develop adaptation and mitigation strategies. She also coordinates the parallel work at the NFRF partner institutions, University of Colorado Boulder and the Oslo School of Architecture and Design (with partner communities in Kenya, South Sudan, Norway and Alaska), to achieve the overall project goal of creating a Global Water Security Toolkit.

Rachel has practical experience working with and learning from rural communities and small-scale drinking water systems around the world, including in Colombia, Malawi, Nepal and now, Canada. During her M.A.Sc., she used both qualitative and quantitative research methods to improve microbial water quality monitoring in resource-limited contexts. Rachel has also held consulting roles for UNICEF and In Exchange, where she gained further insight into how research is practically applied to create meaningful impacts. Additionally, she gained management experience while coordinating the national graduate training programme, WASH Canada. As a non-Indigenous settler, Rachel is committed to continuous learning and unlearning in support of reconciliation.

Photochemical degradation of PFAS in enriched aqueous streams

Email: sesa@student.ubc.ca / LinkedIn

After earning my undergraduate degree at Sharif University of Technology in materials engineering, I moved to Vancouver to further my academic journey. At Simon Fraser University I completed an M.Sc. in chemistry, designing a custom electrochemical cell with conductive-polymer electrodes to achieve energy-efficient water desalination. That work sparked my passion for sustainable water-treatment technologies and brought me to the SWIRL Group at UBC, where I now investigate photochemical pathways for removing PFAS from enriched aqueous streams.
Outside the lab, you’re likely to find me tutoring undergraduate students, strolling along the beach, experimenting with new recipes, or hanging out with friends.
