Emilio Elizalde (born 8 March 1950) is a Spanish physicist working in the fields of gravitational physics and general relativity.
His well-regarded book Ten Physical Applications of Spectral Zeta Functions (1995) was written during the period of his association with CSIC.
Elizalde received the Gold Medal of Tomsk State Pedagogical University, where he also obtained an honorary professorship.
[1] As of November 2013[update], the Astrophysics Data System lists 3035 citations to his publications (self-citations excluded), giving him an h-index of 38.
On 8–10 March 2010, in celebration of Elizalde's 60th birthday, a conference was organized to discuss current progress in the main areas of his research: cosmology, quantum vacuum fluctuations and zeta functions.
