Together, they know all the things

Meet Our Educators

Our educators stay busy finding innovative ways to bring science to young minds. You'll find them on the Lower Level in the Learning Labs teaching classes, taking care of our live animals in the Children's Museum, getting their hands dirty in the field, or going on field trips to nature parks for our Jr. Master Naturalist program — the list goes on and on.

Jessica Liken

Senior Lead Educator — Physical Science and Chemistry

Jessica earned Bachelor of Science degrees in biochemistry, neuroscience, and biology from Brandeis University in Waltham, Massachusetts. During her undergraduate career, she worked in a research laboratory studying the chemistry of proteins involved in neurodegenerative disorders. Specifically, Jessica worked with a yeast model to study how mutations in a protein called FUS/TLS may cause Amyotrophic Lateral Sclerosis, also known as Lou Gehrig’s Disease. A native Texan, Jessica returned to the Dallas area after college and began working as an educator at the Museum of Nature & Science at Fair Park. She has held several positions at the Perot Museum since its opening in 2012, including her current role as Senior Lead Educator — Physical Science and Chemistry. When she's not on the 5th floor working on curriculum or collaborating with other departments, she can be found teaching programs in the Learning Labs, presenting auditorium shows at schools across North Texas, or training Museum Educators on exciting new physics and chemistry demonstrations. In her spare time, she enjoys cheering on the Texas Rangers, working on her wobbly yoga skills, and baking science-themed cakes and cookies.

Chris Strganac, Ph.D.

Lead Educator — Paleontology and Earth Science

Chris earned his M.S. and Ph.D. in Earth Science from Southern Methodist University. He specialized in vertebrate paleontology, applying chemistry to fossils to understand the age and environments of the ancient coast of Angola. Chris participated in field expeditions to Alaska’s North Slope, the Antarctic Peninsula, and the African countries of Ethiopia and Angola. Prior to this, Chris spent two seasons as an interpretive park ranger at John Day Fossil Beds National Monument in Oregon. When Chris isn’t at his desk writing curriculum or reviewing Museum content, he is teaching in the Learning Labs, getting his hands dirty with rocks and soil, or looking up at the day’s clouds.

Jessie Crowley

Lead Educator — Naturalist

After graduating from the University of Illinois with a Bachelor of Science degree in animal science, Jessie worked as a herpetologist at the Dallas Zoo. While there, she worked with over 300 different species of reptiles and amphibians, both exotic and native to Texas. While employed by the zoo, she traveled to Panama, Anegada (British Virgin Islands), and Australia to participate in various research projects. Jessie accepted a job at the Perot Museum in 2012 as the Lead Naturalist Educator. When she is not teaching school programs or camps, you can find her writing curriculum, taking care of the live animal collection, or leading the Jr. Master Naturalist program. Being an active Texas Master Naturalist, she enjoys volunteering her time to educate youths and adults about local flora and fauna. Jessie’s other interests include running, rock climbing, yoga, sewing, hiking, and photographing nature.
