Kylie Boenisch-Oakes

Kylie Boenisch-Oakes (in progress) co-advised with Professor R. Scott Summers.
Email: kybo6048@colorado.eduÌý|
Kylie received her BS in Environmental Engineering from Oregon State University in 2020. At Oregon State, Kylie researched the fate and transport of nanoparticles and nanoplastics in environmental systems. After graduating, they worked as an environmental compliance engineer for Intel Corporation, primarily focusing on air-related projects.ÌýAfter working in industry for two years, Kylie decided to pursue graduate school in environmental engineering with a focus on water reuse. Her research focus is disinfection by-products in the distribution system and premise plumbing,Ìýespecially in water reuse scenarios. She thinks wastewater treatment is super cool, so please reach out if you have any interest or questions! Outside of school, Kylie enjoys rock climbing, mountaineering, skiing, hiking, and playing with her dog, Bon.Ìý

Abdulrahman Aljadani (in progress)
Email:Ìýabal5845@colorado.eduÌý
Abdulrahman finished his BS in Civil Engineering from King Abdulaziz University in 2017 in Jeddah, Saudi Arabia. During his early years in BS, Abdulrahman focused on structural engineering fields such as structural analysis and design. In his last two years, Abdulrahman's interests shifted to water resources and hydrology. He researched floods' potential effects on urban areas and how to maintain and minimize these effects. After his graduation, Abdulrahman worked with the Civil Engineering Department at King Abdulaziz University to investigate multiple valleys surrounding Jeddah city. He looked through the solutions that would prevent the city from possible disasters because of floods. He started his MS with new interests and passions to study environmental engineering and research drinking water treatment, water reuse, and water scarcity in developing and arid countries. Currently, he works with Professor Masters in researching lead fate and treatment in consumer tap water. During his free time, Abdulrahman loves baking and making pizza, watching all kinds of sports, hiking, and exploring nature.

Email:Ìýclbo4168@colorado.eduÌý
ClaireÌýis originally from the mountains in ÃÛÌÇÖ±²¥. She received her BS in Chemistry from Cal Poly SLO in 2020. At Cal Poly,ÌýClaireÌýresearched the synthesis of oxime ethers. She decided to come back to ÃÛÌÇÖ±²¥ and is now pursuing a chemistry graduate degree at ÃÛÌÇÖ±²¥ Boulder. Despite her background being organic synthesisÌýClaireÌýcurrently researches corrosion control treatments (CCTs) to prevent lead from leaching into drinking water. She primarily uses advanced imaging techniques (XRD-CT and uCT) to obtain unprecedented characterization of the lead pipe scales. Outside of school, she loves toÌýski, climb, hike, camp, and hang out with her two cats!
