As a young child, every time Christa told her mom she was “bored” her mom would respond “Well then, you can either play outside or do a chore!” When given the choice, she chose to play outside, exploring the woods and creeks near her house. She also spent most weekends and summer vacations at the lake by her grandparents home or on trips to the ocean. The exposure to water as a child led her down a path of environmental biology with a focus on marine life. Christa worked as a marine biologist in New York, Hawaii, and Australia, studying cetaceans, specifically spinner dolphins and humpback whales. In addition to her research background, she created outdoor education programs and coordinated volunteer efforts for marine non-profits. When she moved to New Mexico it was quite an adjustment! She now loves the dry air, breathtaking mesas, canyons, and bright blue skies. Christa has three children and is thrilled to raise them in such a kind, loving, and beautiful community. Christa joined the PEEC staff in June 2016.
Ashleigh has loved animals for as long as she can remember. Some of her first memories in nature are taking trips with family to Estes Park and Yellowstone. It was while hiking through these beautiful landscapes and seeing the wildlife that lived there that she knew she had found her passion. Ashleigh attended college at Texas A&M University and studied Wildlife Ecology. She also found her love for teaching, minored in education, and student taught in a high school biology class. Prior to graduating, she interned with the Kodiak National Wildlife Refuge in Alaska as an instructor for their outdoor science camp. She enjoys skiing and hiking with her dog, Lincoln. Ashleigh joined the PEEC staff in September 2019.

Mouser Williams
Board Secretary
Growing up in Pojoaque, Linda came to know the Española Valley, Los Alamos, and Santa Fe well. Early years spent hiking, swimming, skiing, and exploring on horseback with her sister and brother gave Linda a deep appreciation of northern New Mexico’s natural and human ecologies, histories, and prehistories. Being a child of an elementary school teacher mother and engineer father taught her the value of life-long learning. As an adult, Linda has continued to enjoy the outdoors with her husband and many friends, backpacking, rafting/canoeing/kayaking, hiking, and skiing while living in Colorado and Utah and since she has returned to northern New Mexico to stay. Board member since October 2018.
Galen Gisler was born under the dark and starry skies of eastern New Mexico and eventually found his way back to his home state. With a Bachelor’s degree in physics and astronomy from Yale University and a Ph.D. in astrophysics from the University of Cambridge (England), Galen went on to postdoctoral positions at the Leiden University Observatory (Netherlands) and Kitt Peak National Observatory (Arizona). He spent two years at the National Radio Astronomy Observatory in Charlottesville, Virginia, where he met his wife Susan. In 1981 he began a 25-year career at the Los Alamos National Laboratory. Galen has been involved in a variety of activities including extragalactic jets, particle beams, plasmas, astronomical transients, adaptive processing, and hydrocode simulations of impact processes and tsunamis. In 2006 he and Susan moved to Norway where Galen held a senior research position at the Center for the Physics of Geological Processes at the University of Oslo. They returned to Los Alamos in late 2012 to enjoy the mountains. Galen and Susan have two children: Andy, an aerospace engineer at ASTRALite in Boulder, and Ellie, an artistic manager at the Caramoor Performing Arts Center in New York. They have one granddaughter, Fiona, who is gradually learning the physics of bipedal locomotion. Board member since October 2019.
Angela Lopez was born in Colorado, however, she has spent most of her life in New Mexico where she has developed a deep appreciation for the Rocky Mountains and desert landscapes. Raised in Pojoaque, she spent long summer days playing in the dirt, watching wildlife on hikes, and exploring new places. Angela attended New Mexico State University and received a Bachelors of Arts and Sciences in Elementary Education (K-6) with an emphasis in Science, endorsements in Bilingual and TESOL Education, and a minor in Spanish. Currently, she is completing her masters in Curriculum and Instruction: Learning Design and Technology. She teaches fourth grade at Barranca Mesa Elementary and enjoys teaching science the most. She has been very fortunate to have PEEC as a learning resource for her students for the past three years. From field trips to the Valles Caldera to learn about erosion and stream ecology to in-class models of aquifers, PEEC has taught her students about nature in such a hands-on and meaningful way! Angela has also helped on the PEEC Education Board and work with nature-loving students as a counselor for PEEC’s summer camps. While teaching and graduate school keep her busy, in her free time she enjoys hiking, camping, fishing, rock climbing, mountain biking, skiing, snowboarding, rafting, kayaking, and traveling to National Parks. She looks forward to using her education background and love of nature as a member of the PEEC Board. Board member since October 2018.
