While most of his research focused on fluid mechanics and climate change/resiliency, he has done work in material science, geotechnical engineering, and integrating social sciences into engineering environments. He was the president of UNH’s Engineering Honor Society, Tau Beta Pi, and achieved the rank of Eagle Scout.

Ian spends his free time reading, playing games, drawing, and working on his fish tanks.

Wesley Lambert holds a B.S. in Environmental Engineering and an M.S. in Civil and Environmental Engineering from UNH, graduating in 2022 and 2024, respectively. His work at UNH's Coastal Response Research Center focused on oil spill research, with expertise in remote sensing, image interpretation, and stakeholder collaboration.

Wesley developed protocols to validate oil spill remote sensing technologies and advanced the use of UAS-based thermal sensors for detecting and characterizing slick thickness in Arctic and temperate environments. He also built UNH’s Facility for Outdoor Remote Testing, where he tested prototype and response-deployed sensors for detecting crude oil, renewable fuels, and emerging contaminants. Recognized for his contributions, Wesley was nominated as an emerging leader at the 2024 International Oil Spill Conference in New Orleans.
