Siânin Spaur

I am a member of the Aquifer Mapping Group group with a background in stable isotope hydrogeochemistry and paleoclimatology. My research interests lie in understanding the geochemistry of past and modern waters in order to understand interactions between surface water, groundwater, climate, and vegetation.

My master's research focused on reconstructing past precipitation and environmental change recorded by mid-Miocene paleosols in the Española Basin in order to understand how climate change affects the hydroclimate of the southwest US; I hope to continue thinking about how water, climate, and geology interact through my work in the Aquifer Mapping Group.
