Alexandra (Alex) Apgar's childhood was dedicated entirely to learning more about the world around her. She became particularly enamored by fossils after discovering several rugose corals in her backyard. She also developed an interest in geology after she uncovered multiple turquoise pebbles. Though these pebbles turned out to be from a previous owner's fish tank, her fascination with rocks and prehistoric creatures never faded. Apgar's interests have led her to pursue a Master's degree in the Department of Earth & Planetary Sciences.

Her current work with Professor Gary Weissmann and Associate Professor Jason Moore focuses on using modern analogue rivers to identify and classify the paleoecology of sedimentary basins within the Chinle (Late Triassic) and Nacimiento (Early Paleocene) formations. In addition, Apgar is interested in education and outreach, and she plans to work as a museum researcher and an educational director.
