Trevor Lohman
Neuroscience Researcher
Trevor Lohman is a clinical research neuroscientist, professor, and author whose academic path began in cellular and molecular biology before transitioning into gene expression and aging. Currently serving as an assistant professor at a medical school in Los Angeles, Trevor explores the intersection of neuroscience and cardiovascular disease. Despite a successful scientific career, Trevor experienced a seismic worldview shift. Once a staunch atheist deeply immersed in rationalism, he began to question the very foundation of his beliefs. His journey—driven by curiosity, intellectual honesty, and a deep love of science—led him not away from reason, but toward faith. His debut book, God’s Eye View, challenges the modern cultural divide between science and spirituality and reclaims the spiritual heritage at the roots of scientific inquiry.
