Manu Seyfzadeh is of German and Persian descent. He grew up in Germany and Iran during his early years and emigrated to the United States at age twenty to study medicine. After four years of premedical college education and eight years of medical and science training at the University of California, Irvine, he earned his M.D. and Ph.D. degrees and went to Baylor School of Medicine in Houston, Texas, for his internship. From 1996 to 2001, he specialized in dermatology and participated in the UCLA S.T.A.R. program to train as a medical scientist researching in the field of molecular immunology and targeted anti-cancer drug design.

Since 2002, he has worked as a clinical dermatologist in private practice
and at various clinics in California, Arizona, Texas, Idaho, and Wisconsin.
He led the Medical Global Brigades on three charity missions to Nicaragua
and Honduras and co-founded a charity called Esperanza 4 U with Elia
Favela Gutierrez to serve orphans and the poor in Tijuana, Mexico.
His entry into Egyptology and ancient civilizations came with reading
a book, The Orion Mystery, by Robert Bauval and Adrian Gilbert, and
watching a documentary film, The Pyramid Code by Carmen Bolter. These
impressions inspired his studies of archeoastronomy, relearning geometry
and architecture, and eventually self-teaching the hieroglyphic language of
the ancient Egyptians with the book Middle Egyptian by James Peter Allen.
Since 2016, Manu has authored a book about the architecture of the
Great Pyramid and published several papers with Robert Schoch and Robert Bauval about the Great Sphinx, pyramid architecture, the Inventory Stele, and the symbols on the T-shaped pillars at Göbekli Tepe. With Under the Sphinx, he is making his findings available to a wider audience with the goal of bringing the public at large closer to the magic and meaning of numbers and words in ancient Egypt and to help advance the progress of knowledge about how they seeded the origin of ancient civilizations.
