Denver Museum of Nature & Science

Meet our Mentors!

Kristen MacKenzie
Position: Earth Sciences Collections Manager

Kristen revels in the challenges of managing 1.25+ million Earth Science specimens at the Museum. Kristen has worked in collections management at Florida Museum of Natural History, Oregon’s Museum of Natural and Cultural History, and the John Day Fossil Beds National Monument. Kristen’s MS in geology is from the University of Oregon, where she described the paleontology and geology of an Oligocene-Miocene vertebrate site in southern Oregon that she discovered in 2006. Kristen is unreasonably fond of early fossil canid, camelid, and rodent alpha-taxonomy and is always enamored with sedimentary basin fill stratigraphy.

Nicole Neu-Yagle
Position: Earth Sciences Assistant Collections Manager

Nicole loves museums and is obsessed with evolutionary biology. She sees fossils and rocks as the key to understanding what we are: with careful study and imagination, we can see what the world used to be like, how it has changed, and make predictions for the future. Nicole studied biology, geology, and art in college, and completed a masters in museum & field studies. She manages the paleobotany, invertebrate paleontology, and geology collections at the DMNS. Her MS thesis research focused on Paleocene mammals, identifying tiny and diverse mammal species which lived in North America after the non-avian dinosaurs went extinct.
