Dr. Julian Vance
Dr. Julian Vance is an academic researcher, earth scientist, and investigative writer dedicated to exploring the intersection of empirical science, ancient history, and wave mechanics. He holds a Ph.D. in Geoarchaeology and Earth Sciences, where his doctoral research focused on the structural transformation of crystalline minerals and historical supply chains. Driven by a deep curiosity about how ancient cultures interacted with the physical world, Dr. Vance also earned an M.Sc. in Applied Acoustics, bridging the gap between historical architecture, physics, and neuroscience. With over a decade of fieldwork spanning artisanal mining sectors in East Africa to analyzing acoustic resonance patterns in ancient historical sites, Julian brings rigorous fact-checking and data-driven analysis to alternative disciplines. As the Chief Editor and Lead Researcher at 3Diamond, his mission is to separate empirical scientific fact from modern misinformation, offering readers deeply researched, ethical, and intellectually stimulating perspectives on mineralogy, sound physics, and ethnobotanical history.
