The topic of this workshop, and of all previous workshops of the same project, was for-mal reasoning and computer programming based on type theory: languages and computerized tools for reasoning, and applications in several domains such as analysis of programming languages, certified software, mobile code, formaliza-tion of mathematics, mathematics education. The workshop was attended by more than 100 researchers and included more than 40 presentations. We also had three invited lectures, from A. Asperti (University of Bologna), G. Dowek (LIX, Ecole polytechnique, France) and J. W. Klop (Vrije Universiteit, Ams-terdam, The Netherlands). From 27 submitted papers, 19 were selected after a reviewing process. Each submitted paper was reviewed by three referees; the final decisions were made by the editors. This workshop is the last of a series of meetings of the TYPES working group funded by the European Union (IST project 29001, ESPRIT Working Group 21900, ESPRIT BRA 6435). The pro-ceedings of these workshops were published in the Lecture Notes in Computer Science series: TYPES 1993 Nijmegen, The Netherlands, LNCS 806, TYPES 1994 B˚astad, Sweden, LNCS 996, TYPES 1995 Turin, Italy, LNCS 1158, TYPES 1996 Aussois, France, LNCS 1512, TYPES 1998 Kloster Irsee, Germany, LNCS 1657, TYPES 1999 L¨okeborg, Sweden, LNCS 1956, TYPES 2000 Durham, UK, LNCS 2277, TYPES 2002 Berg en Dal, The Netherlands, LNCS 2646, TYPES 2003 Turin, Italy, LNCS 3085, TYPES 2004 Jouy-en-Josas, France, LNCS 3839, TYPES 2006 Nottingham, UK, LNCS 4502, TYPES 2007 Cividale del Friuli, Italy, LNCS 4941. ESPRIT BRA 6453 was a continuation of ESPRIT Action 3245, Logical Frame-works: Design, Implementation and Experiments. TYPES 2008 was made pos-sible by the contribution of many people. We thank all the participants of the workshops, and all the authors who submitted papers for consideration for these proceedings. We would like to also thank the referees for their effort in preparing careful reviews. March 2009 Stefano Berardi Ferruccio Damiani Ugo de’Liguoro Organization Referees A. Abel J. Adamek T.
