Dr. Faran Vahedian earned her Ph.D. in Civil and Environmental Engineering from the Colorado School of Mines in 2024, where she conducted advanced research on PFAS contamination in vadose zones, funded by the Department of Defense’s Strategic Environmental Research and Development Program (SERDP). She holds a Master’s in Water Engineering from the University of Guelph, Canada (2021), focusing on water quality and sustainable water management. Her undergraduate degree is a Bachelor of Science in Civil Engineering from Shahid Beheshti University, Tehran, Iran (2014), where she first gained foundational knowledge in environmental and civil engineering. Dr. Vahedian’s academic journey has equipped her with specialized skills in laboratory analysis, groundwater modeling, and environmental systems, allowing her to contribute significantly to research on PFAS contamination and remediation strategies.

Experience 

Dr. Vahedian has a diverse and extensive background in environmental engineering and hydrogeology. From 2021 to 2024, she worked as a Graduate Research Assistant at the Colorado School of Mines, leading a SERDP-funded project on the fate and transport of PFAS in vadose zones. She conducted lab experiments, numerical modeling, and collaborated with HYDRUS developers to refine models for groundwater systems. Prior to that, from 2016 to 2021, she worked as a Hydrogeologist, conducting field characterization, groundwater quality assessments, and developing Python-based tools for groundwater data analysis. Her experience extends to Wastewater Treatment Plant Design Engineer (2014-2016), where she optimized water treatment systems, conducted water sampling, and ensured compliance with environmental regulations. Dr. Vahedian’s practical skills in hydrological modeling, GIS analysis, and environmental risk assessments complement her research expertise, particularly in sustainable water management and environmental remediation projects.

Research Focus 

Dr. Vahedian’s research focuses on the environmental fate and transport of PFAS (Per- and Polyfluoroalkyl Substances), particularly in the context of aqueous film-forming foam (AFFF) contamination. Her work seeks to understand the mechanisms behind PFAS contamination in vadose zones and groundwater, exploring air-water interfacial partitioning and solid-phase sorption processes. She has applied numerical modeling and laboratory experiments to simulate PFAS movement and develop remediation strategies. Additionally, Dr. Vahedian has worked on groundwater flow modeling and sustainable water management, with particular emphasis on modeling hydraulic cross-connections in bedrock aquifer systems and evaluating the impact of fertilizers on groundwater quality. Her research aims to improve understanding of subsurface contamination, develop tools for environmental monitoring, and enhance strategies for the remediation of contaminated water systems. She collaborates closely with model developers and researchers to refine tools and models for groundwater contamination analysis.
