Harrison B. Smith is a researcher at the earth-life-science-institute (ELSI), Institute of Science Tokyo. He co-developed (with lana-sinapayen) the agnostic population-statistics biosignature detection method based on panspermia and environmental modification assumptions, published April 2026. The method detects life across exoplanet populations via statistical correlations without requiring knowledge of life’s specific chemistry. See src-panspermia-agnostic-biosignature-2026-04.
