Dennis Wilson received his Ph.D. in Mechanical Engineering from the University of Texas at Austin in 1977. He has more than 40 years of experience in industry, government, and university research and has over 60 peer-reviewed technical publications. His expertise includes: energetic materials, nanomaterial synthesis, hypervelocity physics and aerothermodynamics.
Prior to entering the private sector in 1999 he was a professor in the Mechanical Engineering Department at The University of Texas at Austin for 22 years.
In March 2005, he accepted Jesus Christ as his Lord and Savior. Before that his worldview was most closely identified with a secular humanism and religious pluralism.
Sarah Salviander received her Ph.D. in Astrophysics from the University of Texas at Austin. She was a researcher at UT for sixteen years, where she specialized in the study of quasars, supermassive black holes, and galaxies. She is the author of several peer-reviewed journal papers and a comprehensive Astronomy & Astrophysics homeschool curriculum. She is currently writing a book on the most common scientific attacks on Christianity and how to refute them.
Sarah was raised atheist in a secular country (Canada), and was influenced by Objectivist philosophy. She converted to Christianity while studying for her doctorate, in large part because of the compelling evidence for God she observed through her scientific work. Sarah retired from UT in 2017 to focus on her ministry work. She now spends most of her time writing and lecturing on topics of science and religion, but remains active in scientific research at a small, private astrophysics institute.
John earned a Masters of Electrical Engineering at the University of California Santa Barbara. His career has focused on the design of hardware and software for real-time, asynchronous computer controlled systems. This has included radar jamming (ECM), cellular switches, and high-speed options trading.
John became a Christian in his freshman year of college after learning that God’s merit could not be earned by good deeds, but only by trusting in the work of Jesus Christ for him on the cross. John has been involved in apologetics for over 30 years. His areas of interest include Islam, Mormonism, Jehovah’s Witnesses, science, philosophy, and theology.
Ed LaBelle received his B.S., Electrical Engineering from Texas A&M University in 1989. He has worked in the semiconductor industry as a process and project engineer since graduation. He was fortunate to get his first job at Advanced Micron Device in Austin, Texas (now Cypress Semiconductor.) He currently works for the semiconductor equipment manufacturer Applied Materials as a consulting engineer.
Ed was brought back to his Christian faith in 1997 through conversations with one of his customers at Motorola Austin. Ed subsequently became a member of Hope Presbyterian Church where he and his wife taught Children’s Church on Sunday mornings. Later he moved to Bethany United Methodist Church and became involved as a Faith Friend for confirmation students. He has been a high school Sunday school teacher and is currently a co-coordinator for Bethany’s confirmation class.
Ed finally got around to buying his first telescope in 2009 and immediately started connecting with other amateur astronomers in the Austin area. He started going to astronomy outreach events where he found deep joy in sharing his passion for astronomy with people. Ed would also take his telescope to church related events where he would quote Psalm 19:1-2:
“1 The heavens declare the glory of God; the skies proclaim the work of his hands.
2 Day after day they pour forth speech; night after night they reveal knowledge.”
After a Walk to Emmaus retreat in September 2015, Ed was left with a nagging question: Why limit Psalm 19 to just church related events? Why not quote these verses for secular events too? The Holy Spirit used this retreat to convince Ed that he needed to share Psalm 19 with everyone that looks into his telescope. So in March 2016 a new sidewalk astronomy ministry was born called Psalm 19 Astronomy. The mission is “sharing the beauty and majesty of God’s universe through astronomy.”
Ed along with other friends host a Psalm 19 Astronomy event about once a month at the Pfluger Pedestrian Bridge near downtown Austin. They set up telescopes and invite the public to see the beauty and majesty of God’s universe and use this opportunity to share their faith in Jesus Christ. This ministry has expanded to other locations in Texas and North Carolina as word gets out about using astronomy to “declare the glory of God.”
You can learn more about this ministry at the Psalm 19 Astronomy Facebook page or contact him at firstname.lastname@example.org.

Born a sinner in 1966, Victor Vigorito found an America engulfed in political and social turmoil. Not surprisingly, doubt and uncertainty characterized his place in the world until he was 20 years old. Along the way, when Victor was nine, Christ revealed Himself and made the youth a saint. His ultimate future secured, Victor nevertheless struggled with doubts over the uniqueness of Christianity, amid the competing truth claims of the world’s religions. His early interest in history and science, eventually leading to an M.A. in history at Texas State, was partly born out of his desire for a grounded, tested faith that was impervious to the assaults of evolution, pluralism, and post-modernism. To his pleasant surprise, Victor found the evidence of legitimate science, along with God’s apparent hand in shaping history, very supportive of Christian faith. In pursuit of defending that faith, Victor obtained an M.A. in Theological Studies from Austin Graduate School of Theology. He presently equips saints through two Bible studies at Hill Country Bible Church. He is also an adjunct professor at ACC, equipping saints and sinners with historical perspective.
