Past-President: Harry Poe

Harry (Hal) Poe is Charles Colson Professor of Faith and Culture at Union University in Jackson, Tennessee. He co-edited with Stan Mattson the science and religion papers from the 2002 C. S. Lewis Summer Institute that will be published as What God Knows: Time, Eternity and Divine Knowledge, and is also a descendant of Edgar Allan Poe. As a theologian, Hal belongs to ASA to take part in the conversation with people in the sciences who have a commitment to Christ but whose theology of science may be determined by traditions they are not even aware of.


President: Keith Miller


Keith Miller is currently a research assistant professor in geology at Kansas State University. He grew up in Lancaster County, Pennsylvania, a rural area west of Philadelphia that is home to large Amish and Mennonite communities. His parents were strong Christian models and encouraged Keith’s interest in the sciences. Since he always enjoyed nature, (collecting rocks, shells, and insects), Keith had an early interest in geology. He attended Franklin & Marshall College where he became fascinated with paleontology, then pursued that subject as a graduate student at SUNY Binghamton and the University of Rochester. Keith’s research interests have included the preservation and paleoecology of marine invertebrate communities, the record of short-term cyclicity within the geologic record, and models for sea level and climate change in the US mid-continent during the Pennsylvanian & Permian Periods. In his free time, Keith enjoys nature and landscape photography.

Vice-President: Johnny Lin

Johnny Lin is a Professor of Physics at North Park University in Chicago. He graduated from Stanford University with a B.S. in Mechanical Engineering and an M.S. in Civil Engineering-Water Resources. After working as an environmental engineer, he returned to school and received his Ph.D. in Atmospheric Sciences from UCLA. His atmospheric science research is focused on stochastic convective parameterizations, ice-atmosphere interactions in the Arctic, and simple frameworks for modularizing climate models. He is also interested in issues of Christian environmental ethics. His interest in the intersection between faith and science stems from a conviction built-up, starting in college and graduate school, that God made us to love Him with all of our being, including through our limited thinking about how creation works. His favorite ice creams are daiquiri ice and French vanilla.

Secretary-Treasurer: Lynn Billman

Lynn L. Billman retired in September 2013 from the National Renewable Energy Laboratory (NREL), a Department of Energy laboratory in Golden, Colorado.  Lynn grew up in Chicago, and loved chemistry, physics, and math in high school.  She graduated with a BS in chemistry from the University of California, Berkeley, and is a member of Phi Beta Kappa.  She went to work as an analytical chemist with Chevron, and later moved into management analysis and planning.  Making a big move with her husband from California to Colorado, she landed a job (finally!) as a science writer with what later became the National Renewable Energy Laboratory.  During more than 26 years of service, Lynn’s work spanned all technology and mission areas in support of NREL executive management, research program planning, campus design and sustainability, communications, and energy market and policy analysis.  Her career is a testimony to all the different ways a person can apply a chemistry degree!  She became a Christian at a women’s retreat in 1990, and has served in a variety of churches since then.  Lynn’s passion is helping people succeed, and has taken on the challenge of developing the ASA affiliate group "Christian Women in Science.”  She lives in Lakewood, Colorado with her German Shepherd Toby, and enjoys having all her children and grandchildren nearby.

Member: Stephen Moshier

Steve Moshier traces his interest in science to the first American spaceflight in 1961 (he was in kindergarten and his grandmother gave him a toy rocket that afternoon). Following the Apollo explorations of the Moon and developing a love of the outdoors through Boy Scouting led to a major in geology at Virginia Tech. At the same time, encounters with Christians in the dorm and geology department led him to faith in Christ. After completing an MA in geology from SUNY Binghamton, Steve entered the world of oil and gas exploration and development. The research question for his eventual PhD dissertation came to Steve during an oil company assignment in North Sumatra. As an Alumni Foundation Fellow at LSU, he studied the formation of microporosity in limestone petroleum reservoirs in the Middle East and Indonesia. Steve joined the ASA when he was at LSU, where he appreciated the fellowship of ASA members there on the science faculty. After completing his PhD in 1986, Steve joined the geology faculty at the University of Kentucky and in 1991 moved to Wheaton College, where he serves as chair of the Department of Geology and Environmental Science and Director of the Wheaton College Science Station. At Wheaton, Steve enjoys the opportunity to mentor future scientists and help students of all majors navigate the currents running between science and faith. Over the past 15 years, Steve has engaged in field geoarchaeological research in the Sinai, Egypt and Israel, and has created maps showing the land as it appeared during biblical history.

Early Career Rep: Hannah Ryan

Hannah Ryan grew up in the sunny central coast of California. She attended Westmont College, graduating in 2013 with a double major in chemistry and biology. Hannah first started to pursue science because she wanted to become a physician, but was captivated by the elegant and mysterious world of molecules that she discovered in her education. She conducted research in physical chemistry with Dr. Allan Nishimura while at Westmont, and then moved to Colorado to pursue graduate studies in chemistry. She now attends the University of Colorado Colorado Springs and is working on her masters degree in computational chemistry. She adores reading theology and Jane Austen; in her spare time, she enjoys hiking in the Rocky Mountains, playing the violin, and cooking Italian food.
