Research Interests

Prof. Franco’s main research interests are in theoretical high energy physics. More concretely, he works on String Theory and Quantum Field Theory. His work spans a broad range of topics, ranging from formal aspects of String Theory to new scenarios for physics beyond the Standard Model. He has made seminal contributions in various areas, most notably: String Phenomenology (he introduced Intersecting Braneworlds, which have become one of the most successful and thoroughly studied scenarios connecting String Theory to particle physics), the AdS/CFT correspondence (he discovered the first infinite families of explicit AdS/CFT pairs, drastically changing the status quo of the correspondence), the connection between geometry and quantum field theory in String Theory and particle physics model building (mainly in the context of supersymmetric extensions of the Standard Model).


At present, a great part of Prof. Franco's research is devoted to charting the vast space of quantum field theories, exploiting string theory tools to determine their dynamics and uncovering new dualities.
