He has been a postdoctoral fellow of the Social Sciences and Humanities Research Council of Canada, a visiting scholar at the Institute for Medieval History (Boston University), the Institut Milà i Fontanals (Consejo Superior de Investigaciones Cientificas, Barcelona) and the Institut d'Estudis Catalans (Barcelona).
Until 2012, he was an Associate Professor of History at the University of California Santa Cruz (cross-appointed to Jewish Studies). In 2009-10 was a Visiting Associate Professor of Spanish and Portuguese at the University of Colorado at Boulder. Presently he is an Associate Professor (and Director of Undergraduate Studies) at CU Boulder (affiliated with History, Humanities and Jewish Studies), a Research Associate in Humanities at the University of California Santa Cruz , a project member at the Institut Milà i Fontanals (CSIC, Barcelona), and an external faculty member of the Università di Messina (Italy). Recently, he collaborated in a multi-year project sponsored by the Université de Paris, entitled "Elites rurales méditerranéennes au Moyen Âge (Ve-XVe siècle)." He regularly delivers lectures, talks and conference papers in North America, and Europe (over 90 to date), and organizes conferences and panels at academic meetings (over 20 to date).
He has been awarded grants, fellowships, honors and prizes from the Spanish Ministry of Exterior, the Spanish Ministry of Education, the Catalan government, the University of California, the University of Toronto, the Government of Ontario, the IODE , the Canadian Association of University Teachers, and the American Historical Association. In 2005 he received a UC President's Research Fellowship in the Humanities in support of an archival project, "Conflicts of Interest: Minority Administrative Elites in 14th-Century Aragon."

Fagg Prize, and it was been selected by the American Historical Association for the "Premio del Rey" in 2007. In 2009–10 he held a research fellowship from the National Endowment for the Humanities. This led to the publication of Muslims of Medieval Latin Christendom, ca. 1050-1614 ( Cambridge University Press, 2014), a book that received the Middle East Studies Association Albert Hourani Prize in 2014. Infidel Kings and Unholy Warriors: Power, Faith and Violence in the Age of Crusade and Jihad, a "cross over" book, meant for a popular as well as a scholarly audience was published by Farrar, Straus & Giroux in August 2014.

The Mediterranean Seminar has an editorial and advisory board made up of leading authorities and new scholars in a range of disciplines, and over 600 affiliates worldwide. Programs Catlos and Kinoshita have co-directed under the aegis of the Mediterranean Seminar include a long-standing research group at UCSC, a 14-week Residential Research Group at the UC Humanities Research Group, a France-Berkeley exchange program with the Université de Paris and the Université Marc Bloch, three NEH Summer Institutes for College and University Professors (2008, 2010, and 2012, with the fourth proposed for 2015), and a workshop at the 13th Mediterranean Research Meeting, hosted by the European University Institute (Florence & Montecatini Terme, Italy), as well as many other programs. They established the UCSC Center for Mediterranean Studies in 2009 and the Mediterranean Consortium, a loose organization of Mediterranean Studies programs around the world. In 2010 he began as PI and co-Director (with Kinoshita) of a 5-year Multi-Campus Research Project in Mediterranean Studies, which has received a $500K grant from the University of California. The core of the MRP Program consists of a series of workshops, conferences and other activities aimed at fostering national and international scholarly collaboration, original research and pedagogical development. This program concludes in June 2015. In 2012 Palgrave/MacMillan asked Catlos and Kinoshita to launch a new series, Mediterranean Studies, which they now edit. In 2010 he received an Innovative Seed Grant from the University of Colorado at Boulder to launch a Mediterranean Studies group there, and in collaboration with the UC project and the Mediterranean Seminar.

Here, he established the CU Mediterranean Studies Group at the University in collaboration with Claire Farago (Art & Art History, CU Boulder). Nearly 40 faculty and graduate students from 13 departments at CU Boulder and neighboring institutions participated in the first year's program, which was supported by a number of CU Boulder programs and departments. In 2011-12 they expanded the program with the support of an Innovative Seed Grant, establishing an advisory board and putting together a program featuring local faculty, visiting scholars, and a conference in conjunction with the University of California Mediterranean Studies Multi-Campus Research Project. The 2013-14 and 2014-15 programs featured workshops, round-table events, film screenings and visiting scholars (see program here).
In July 2012 he resigned his position as Associate Professor of History at UCSC, having accepted an appointment as a Research Associate of the Humanities Division. This was renewed in 2014. He continues as co-Director of the UCSC Center for Mediterranean Studies, and the UC Mediterranean Studies Multi-Campus Research Project.

In 2009 he edited a festschrift in honor of this dissertation supervisor, Worlds of History and Economics. Essays in Honour of Andrew M. Watson (Valencia: Universitat de Valencia). His essay, ""Accursed, Superior Men": Political Power and Ethno-religious Minorities in the Diverse Medieval Mediterranean" was co-awared (together with a work by Thomas F. Glick), the 47th Annual Walter Prescott Webb Essay Prize from the University of Texas at Arlington, and will be published in Comparative Studies of Society and History.
A number of articles are at press, and several book projects are in progress, including Paradoxes of Plurality: Ethno-Religious Identity in the Medieval Mediterranean and Beyond and The Crucible of the West: Al-Andalus and the Muslims of Spain, 650–1650 [working title] (Basic Books; for Fall 2016)The Crucible of the West: Al-Andalus and the Muslims of Spain, 650–1650, both under contract with Basic Books.

Other current undertakings include a number shorter archival studies on the Muslims and Jews of late Medieval Christian Spain, various projects connected to Mediterranean Studies, and work on a general theory regarding the social and economic interaction of majority and minority ethno-religious groups based on the principle of "conveniencia," in development as Paradoxes of Plurality.
