Alexander Thames

PhD Student, Geosciences and Climate Science Dual Title

Alex Thames is an interdisciplinary scientist with interests ranging from the influence of weather on water resource planning to the evolution of Earth's volatile flux as a function of its deep water cycle. Specifically, he is interested in how synthetically generated data sets can provide exploratory insights into poorly constrained physical processes. When not acting as a scientist, Alex can be found watching and critiquing science-fiction, fantasy, and horror content with his wife, doting on his dog, and coding small videogame projects.


Enock Bunyon

MSc Student, Geosciences

Enock Bunyon was born and raised in Ghana. He attended Adisadel College an all-male Anglican boarding high school ranked top 10 in Africa. After graduating from high school, he moved to the United States for his undergraduate studies at Utica University. He was a peer tutor, geology lab technician, and Utica men’s soccer team member. He graduated from Utica University with a Bachelor of Science in Geosciences. Following his graduation from Utica, He worked in the environmental consulting industry as a Junior Geologist for three years. Enock worked on several EPA, U.S Army Corp, and private projects as a geologist. Enock is currently pursuing his master’s in Geosciences at Penn State University. He is a member of Hadjimichael Research Group, and his research focus is on water resources, Hydrogeology, and Hydrology. He enjoys playing soccer, cooking, and listening to music in his free time.


Madison Hernandez

MSc Student, Geosciences

Madison Hernandez is pursuing her master’s in Geosciences at Penn State. Prior, she received a B.S. in Earth and Environmental Sciences at Lehigh University. Her research interests include hydrogeology, water resources, and planning under uncertainty. She enjoys learning how climate change and anthropogenic forces affect water resources in communities. Outside of research, she often spends her time doing yoga, hiking, and reading.


Ava Spangler

PhD Student, Geosciences and Climate Science Dual Title

Ava is pursuing a PhD in Geosciences and Climate Science. Her interdisciplinary research focuses on using decision-making tools to understand how urban environments can most effectively build resiliency against climate change and other stressors. Ava previously earned a B.Sc. in Civil Engineering from the University of Colorado, where her studies focused on hydrology and water resources. Ava is a big fan of chocolate chip cookies, trail running, and cold brew coffee!


Sierra Wright

BSc Student, Geoscience

Sierra Wright is an undergraduate student studying Earth Sciences at Penn State University, with a particular interest in the geoscience processes. She is working with the Hadjimichael Research Group under the organization Multi-Campus Research Experience for Undergraduates (MCREU). Her research is focused on the classification of flash droughts events in the contiguous US.

Hollin Williams

BSc Student, Geobiology

Hollin Williams earned an undergraduate degree in geobiology with a minor in marine science. Her interests include studying how marine populations and ecosystems are impacted by the effects of climate change, if and how they may be adapting, and how mitigation techniques may be able to aid in their success. In addition, she’s interested in how present-day ecosystems differ from those of the past under different environmental conditions and how sustainable they will be in the future.
