Puthoff co‑founded the Stanford Research Institute's remote viewing program and later conducted research on zero‑point energy as a potential energy source. He contributed to the Advanced Aerospace Threat Identification Program.

Puthoff earned a PhD in electrical engineering from Stanford University. He worked at Stanford Research Institute and later founded EarthTech International to research advanced physics concepts.

Notable works: Numerous papers on zero-point energy, quantum electrodynamics, and remote viewing.

Representative statement: Puthoff has suggested that some UAP may utilize propulsion systems based on modifications of spacetime geometry.

Puthoff's work spans mainstream physics and controversial topics. His government‑funded research on remote viewing and UAP has made him a polarizing figure, respected by some for his openness to unconventional ideas and criticized by others for engaging in pseudoscience.

Puthoff continues to influence both the remote viewing community and UAP research through his publications and government contracts.
