[3] Despite his position in times of serious economic crisis, he achieved important milestones in teaching infrastructures, research, education and use of the Basque language in the university.

This work was the basis of his doctoral thesis, entitled "Partially Visible Part Recognition via Artificial Vision in Industrial Environments" in 1987.

In February 2017 he was appointed the first visiting professor in the Eloise Garmendia Bieter at Boise State University (BSU) where he taught a course under the title "Nation making: Education, Science and Media".

In 2011 he was co-author with Maider Huarte and Purificación Saiz of Basque-language books Telekomunikazio-sare eta zerbitzuak: Teoria (English: Telecommunication Networks and Services: Theory) and Telekomunikazio-sare eta zerbitzuak: Ariketa ebatziak (English: Telecommunication Networks and Services: Problems Solved).

In 1986 he set up the company Adicorp, S.A. with a view to commercially exploiting the results of his doctoral thesis in the field of artificial vision.
