Jennifer Eglin-Mosley

Jennifer Mosley has taught students and has been a teacher-leader and mentor in schools of diverse populations for 16 years. One of her main goals is to always make positive, productive, and pertinent contributions to conversations that affect the lives children and educators alike. She presently works in Aldine ISD, where she has been recognized for student growth, as being an "Extra-miler" two years in a row, and was voted Teacher of the Year for her campus in school year 2019-20. She continues to do her best to equip and empower her students and encourage her colleagues daily.

Dr. Lori Feaga

Dr. Lori Feaga received her Bachelor of Science degree with High Honors in Astronomy from the University of Maryland in 1997.  She then continued her education at the Johns Hopkins University where she successfully defended her doctoral thesis and received her Ph.D. in Astrophysics in 2005.  

Currently an Associate Research Scientist at the University of Maryland, Dr. Feaga is a planetary scientist focusing on the molecular composition and distribution of ice and gas surrounding small bodies in the Solar System (e.g., comets, asteroids, and Kuiper Belt objects) and how they relate to the protoplanetary disk from which the Earth formed. Her observing techniques include ultraviolet to infrared spectroscopy, visible imaging, and time-domain surveys.  Dr. Feaga has extensive NASA mission experience, having held instrument, science, and outreach roles on the Deep Impact, EPOXI, Comet Hopper, and Rosetta missions, and intends to lead her own small satellite mission in the future.  

From an early age, Dr. Feaga received encouragement and support from her family to pursue a career in astronomy, yet often found herself immersed in male dominated STEM classes and professional settings.  It is because of these experiences, combined with her interest to share her own science, promote science literacy, and inspire others to enter the STEM fields, that she continually engages in education and outreach and enthusiastically presents her work to students of all ages.

Dr. Jen Nekrease

Dr. Neakrase currently teaches 8th grade science in the Science Magnet program at Sierra Middle School in Las Cruces, NM. Previously she taught mathematics (and one year of music) at a private elementary school for gifted and talented children.

After earning her Bachelor's in Astronomy and Astrophysics and her Masters in Physics, she went on to earn her PhD in Science Education. She was particularly interested in how students were learning astronomy and physics, which led her into curriculum development.

Her research focuses on the pedagogical content knowledge, practices, and nature of science beliefs of in- and out-of-field teaching for physics and elementary teachers.

Emily Olsen

As a twenty-year educator, Emily has spent the bulk of those years in high-needs, low socioeconomic schools.  Her experiences have focused not only on the academic needs of her students, but more often on their emotional, behavioral, and social needs.  Though she started out teaching elementary school students, she quickly found her “home” in middle school (and she will tell you it is not for the faint of heart, but she loves it.)  “I grew up in a neighborhood similar to the ones my students live in.  I have seen and experienced much of what they are going through and use that to connect with them.  I encourage my students to set their goals high and try to give them the tools they will need to fulfill them.”  

Macie Rains

Macie is a science teacher from College Station, Texas. She has seven years of experience teaching math, science, and robotics classes to 4th-8th grade students. Currently, she teaches 7th grade science in the Odyssey STEM Academy housed within Bryan ISD. In 2018 she completed coursework to earn her national STEM certification through The National Institute for STEM Education, and in 2020 she earned her masters degree in education administration from Texas A&M University.

Amber Roberts

Teaching is a second career for Amber. She discovered this passion 15 years ago when she rejoined the workforce after staying home to raise her young children.  "There is nothing more satisfying and rewarding than building relationships with the families in my community," she says. "Teaching science is really my vehicle for connecting with people." Currently, Amber teachers middle school science at a small, rural district in northern New York.
