In her free time, Monica enjoys making candle molds and chalkboard art. We are so pleased to have Monica in our department!
Leighton Wilson entered the Applied and Interdisciplinary Mathematics Ph.D. program in 2015. Leighton's love of science and math was inspired by his grandfater who spent his career as a civil engineer and still pulls out his old calculus and differential equations textbooks to do math for fun. Leighton enjoys playing the banjo because of its cultural importance and rich history. Leighton also enjoys the tactile experience of playing and collecting vinyl records. Leighton enjoys Americana, progressive rock, most artists with ties back home to Alabama, and pre-war blues. Leighton completed the Trans-Zion Trek, a 47 mile backpacking route in Zion National Park. "It was quite honestly the hardest thing I've ever done, but the views were spectacular." We are grateful to have Leighton in our department!
