In the UCR he held a professorship in Spanish philology in the School of Philology, Linguistics and Literature and was a researcher at the Institute of Linguistic Research.[6]: 101 [7]
Quesada Pacheco's work on Costa Rican Spanish is rooted in dialectology and historical linguistics. He has investigated the development of Costa Rican Spanish since the colonial era.[8][9] Between the years 1992-2010 he worked on the Atlas lingüístico-etnográfico de Costa Rica (ALECORI) project, the first of its kind for Costa Rican Spanish.[10][11][12]
He later applied his experience with the ALECORI to the Atlas lingüítico-etnográfico de América Central, which aimed at systematically studying the Spanish of Central America by way of dialect surveys.[6] This work cleared the way for the publication of various national linguistic atlases prepared by his students on the Spanish varieties of Belize, Guatemala, Honduras, El Salvador, Nicaragua and Panama.[13]
As for his work with Amerindian languages, Quesada Pacheco has worked extensively on the description of Boruca, Guaymí, Cabécar, Huetar, Chibcha and Paya. His ethnolinguistic studies on the Huetar people and language earned Quesada Pacheco the Premio Nacional Aquileo J. Echeverría en 1997.[2]
