Our Team

Lara Bates, Executive Director

Lara graduated from Indiana University in 2004 with a bachelor’s degree in Public Affairs. For nearly a decade, she served as the Environmental Education and Media Specialist for Lake County’s Solid Waste District. Students referred to her as “The Worm Lady” as she turned their classrooms into a compost heap of exploration. Shortly after completing her master’s degree in Public Management, Lara was presented with an opportunity to work on an unprecedented project to create a Heritage Area for the Calumet region. As the Calumet Heritage Communications Specialist for The Field Museum of Natural History, she devoted two years working towards the designation of the proposed Calumet National Heritage Area, which is still under review through the National Park Service. Lara is over-the-moon to be a part of the Challenger Learning Center team and enjoys each day she gets to blast-off into a voyage of discovery with students that visit the center. When she’s not in space, her favorite past times include traveling with her husband to see their favorite band Phish, spending time with family and relaxing in nature while bird watching. Although Lara doesn’t have any human children at this time, she is a loving mother to her 10-year-old English Bulldog named Icculus.

Karen Cearing, Finance Manager / Sales Coordinator

Karen was born in South Chicago Heights, Illinois, but, has lived in Northwest Indiana since the 6th grade. Karen’s family currently resides in Dyer, Indiana. Karen graduated from Lake Central High school in St. John, Indiana and also attended Purdue University Northwest, taking accounting classes to further her career.  The majority of her professional career has been spent working for local CPA firms where she specialized in non-for-profit and small business accounting. After spending the last two years working for the Crossroads Regional Chamber of Commerce in Merrillville, Indiana, as their Marketing Director, Karen was happy to accept the Business Manager position at Challenger Learning Center. Karen and her husband are very proud of their two beautiful daughters, one who is a teacher and one who attends Indiana University. 

Valerie Hunter, Lead Flight Director

Valerie grew up in the Southeast Side of Chicago, and she remembers always wanting to be a teacher. She graduated from DePaul University in 2005 with a degree in Elementary Education. She spent the next 13 years in the classroom at 3 different elementary schools through the Archdiocese of Chicago Catholic Schools. She has experience with grade levels from second all the way to eighth, but mostly enjoyed the fifth graders she has taught over the years. Valerie loved trying out new ideas in the classroom and having the opportunity to impact the lives of her students. Valerie was interested in joining the team at the Challenger Learning Center because of the opportunity to reach students in new ways and to teach STEM in such fun and creative ways.

Outside of the Challenger Center, Valerie lives in Highland with her husband Brian. They are loving fur-parents to their dog Jake, an adorable and crazy Australian Shepherd they adopted in 2015. It is well-known how much she loves Better Than Ezra (her favorite band, who she has seen in concert almost 50 times!) and the Cubs. She and Brian have so much fun just spending time with their families, whether it’s getting together to watch the Cubs, attending a concert, or visiting her sister in Kentucky.

Emma Rose, Communication and Events Coordinator

Emma Rose isn’t an astronomer, she doesn’t come from the museum world, and before starting at Challenger, she knew very little about space. But a lot has changed in 5 years that she has worked at CLCNWI! Emma is a 2018 graduate from Purdue University Northwest with a degree in Human Development and Family Studies and minors in Psychology and Sociology. She has lived in NWI her entire life and graduated from Lake Central High School in 2014.  Outside of the Challenger Center, Emma is an avid Disney fan and foodie.  She loves to go on vacations with her family and her dog, who is also named Emma!  Emma spends her time at Challenger planning summer camps, running the gift shop, and coordinating public and fundraising events.  She is extremely passionate about her job, and as a part of the CLC team she loves showing people why space is so awesome!

Greg Karas, Flight Director

Commander Greg earned his Bachelors from Valparaiso University in 1976 and his Masters from Indiana University in 1986. For 37 years he served as a fourth-grade teacher in Valparaiso. Through coaching, summer school, Student Council and the Kiwanis K-Kids program, he was fortunate to work with students at every grade level (K-12) during his teaching career. He has had a lifelong interest in space exploration and can vividly remember watching the televised flights of the Mercury astronauts in the basement of Elliott school in Munster when he was a student there. In the 1980s he applied for NASA’s Teacher in Space program and was a semi finalist for the state of Indiana. Greg is the past president and charter member of the Sunrise Kiwanis Club of Valparaiso. He has served on the board of the United Way agency Family House for 25 years. (Family House helps children who have been victims of abuse and neglect.)

Greg’s wife Liz is a Registered Nurse at Porter Regional Hospital. They have two married children named Nick and Natalie and two beautiful granddaughters named Olivia and Miriam, plus amazing twin grandsons, Benny and Lando. Greg loves to read, write, hike at the Indiana Dunes, and take long bike rides on the trails in Porter County. Commander Greg is proud and happy to guide kids at this wonderful STEM institution, because he knows it provides them with a unique and powerful learning experience.

Amy George, Flight Director 

Commander Amy Graduated from Indiana University Northwest with a degree in Elementary Education.  After graduating from college, she taught in the East Chicago Public School system for eight years and in Portage Township Schools for one year.  While teaching, she continued her education and added Middle School Science and Kindergarten Endorsements to her teaching license.  During her time as a classroom teacher, she served as a Science Olympiad Coach and loved teaching her students hands-on science lessons.  Amy is currently a substitute teacher within the Portage Township and Duneland School districts. 

Amy learned about the Challenger Center while she was working on her continuing education classes.  She had the opportunity to visit the center and complete a mission with her classmates and to visit the planetarium.  This unique opportunity is when she realized that she had a passion to study space and pass the knowledge on to her students.  Amy also had the opportunity to bring her 6th grade students to the Challenger Center to participate in a moon mission and her 2nd grade students to participate in a lesson in the planetarium.  Commander Amy is thrilled to join the Challenger team as a Flight Director and is looking forward to watching the excitement of the students build as they work through the tasks of the missions.

When Amy is not teaching, or flying a mission, she enjoys camping, hiking, biking and traveling with her husband. She also enjoys scrapbooking, doing puzzles and baking during the winter months.

Elijah Weathersby, Flight Director

Commander Elijah (or Eli for short) was born on an Easter Sunday in Chicago Heights, Illinois. At about the age of 7 they moved with their family to the Region, to a quaint home in Schererville, Indiana where they attended elementary, middle, and high school. During middle school, Eli had the privilege of attending the Challenger Learning Center, getting first-hand experience with the missions/programs that CLC offers. Having been influenced at a young age by their mother (a nurse in practice for as long as Eli can remember), Eli has always wanted to be in the healthcare field, but generally has appreciated all STEM related work. Post high school, Eli attended Indiana University Northwest from 2014 to 2018 and obtained a Bachelor's Degree in Chemistry with a minor in philosophy/ethics.

Through high school and college, Eli has begun to understand the impact and importance of education in all its facets, hoping that someday each child can surpass their true potential through means of their education. Eli believes that with an educated public, any and every future can become possible. They appreciate not only what the Challenger Learning Center has done for them, but also what they have done for others and what the CLC will continue to do.

Eli is youngest of three siblings (but the middle child if you include two precious dogs) and is a self-acclaimed "baba" to two wonderful nieces. Outside of STEM related work and activities, Eli loves to bust a move and dance, appreciates a challenging sewing project, and loves cosplaying their favorite video game characters.
