Associate Professor of the Department of Philosophy and member of the Center for Research and Training in Artificial Intelligence (CinfonIA) of the Universidad de los Andes. Since 2002 he manages the Research Group on Logic, Epistemology and Philosophy of Science (Philogica) and he is the coordinator of the recently created Latin American Network of Legal Epistemology. His recent research is focused in two large areas: legal epistemology and the philosophy of Artificial Intelligence. In the first, his publications have dealt with the epistemological problems of testimonial, expert and reputational evidence, of the standards of proof and the effects of cognitive biases in the decisions of judges. In the second, his main interest is in the interaction between humans and autonomous artificial systems, in particular, in the factors that favor our understanding of their operation and generate confidence in their decisions.
