Academic Year Adjunct Lecturer
BS, James Madison University
As an instructor, I aim to engage students in active learning by providing hands-on laboratory and field experiences and by providing opportunities for students to use data to better understand Earth systems concepts. I believe a well-designed science course should provide all students with strategies for constructively engaging with science in their everyday lives, and students who are considering the possibility of pursuing a career in science and technology should leave the course with confidence that such a career is within reach.
My research is focused on using the geochemistry of deep-sea sediments to reconstruct the sea-surface temperature and paleoclimate histories of the past ~13 million years. This time interval spans a large range of climate conditions—from the warmer-than-modern times of the late Miocene and early Pliocene to the ice ages of the Pleistocene. I am drawn to studying these long time-scales because they allow us to investigate a much larger range of climate states than is possible with more recent climate records.
