Pedro Miguel Etxenike (Pamplona, 1950) is a full professor of Condensed Matter Physics at the University of the Basque Country. He began teaching at the University of Barcelona in 1978, leaving in 1980 to dedicate himself to politics. For four years he was the spokesperson and director of Education for the Basque Government. In 1984 he resumed his research activities at the University of Cambridge.

Etxenike has centred his research on explaining, using mathematical and computer models, the behaviour of the particles that make up solid bodies and their interaction with external loaded particle beams. Specifically, he has demonstrated the energy losses experienced by electrons according to the distance that separates them from a surface or solid interface. This discovery has been key in understanding what occurs in the scanning tunnelling microscope discovered by Binning and Rochrer, for which they received the Nobel Prize for Physics. Honorary Member of the American Physics Society, Etxenike has been the recipient of diverse honours, standing out among which are the "Euskadi" for Research and the "DuPont" for Science.
