I am a philosopher of science. I work as a research fellow at the Philosophy of Science Department in the Institute for Philosophical Research at the Bulgarian Academy of Science, Sofia. At present I am a Visiting Fellow at the Center for Philosophy of Science at Pittsburgh University and I try to come up with an alternative epistemic conception to the standard empirical revisability in natural sciences.


During the last several years I have worked on the epistemological problem of thought experiments in science and on various issues in contemporary analytic epistemology, mainly a priori knowledge and justification. I am interested in philosophy of mathematics, philosophy of physics and the problems of space and time. I am developing a non-standard version of a priori justification for both mathematics and naturals sciences and I believe that Hugh Everett's Relative State interpretation of quantum mechanics deserves even greater attention than it actually receives today.


I have defended my first PhD in Philosophy of Science department at the Institute of Philosophy, Bulgarian Academy of Science, in February 2006. At present I am concluding my second PhD, this time in analytic epistemology,  at the Central European University in Budapest on topic "A priori Principles and Scientific Knowledge" with advisor Nenad Miscevic. During the winter of 2004 I have worked with Jim Brown on the problems of a priori knowledge and TE at the University of Toronto. Every April I participate in the annual Philosophy of Science Conference in Dubrovnik, Croatia. Among my non-academic interests are videography, filmmaking, scientific journalism, and amateur sport car racing. Here you can find some additional bits about me and my work on the Pittsburgh Center for Philosophy of Science website. Here is the link to the web site of my and my brother's independent film company SofiaFilm. You can reach me at









… the answer is, in essence, that during this century of science’s greatest achievements, most physicists and philosophers have given  up on the idea that the purpose of science is to discover how the world really is. Instead they want to regard it as a mere instrument for making predictions and achieving pragmatic goals.
