For the UCLA Logic Seminar, in April 2016, I gave the lecture Categoricity in Non-Elementary contexts – The Role of Large Cardinals.

For the CUNY Logic Workshop I gave the lecture The Model Theory of some j-functions, in March of 2016.

At the IPM Institute in Isfahan (Iran) I was invited to give a lecture on Semantics on Sheaves (Topological, Metric, etc.) in November 2015.

In November 2015, this colloquium lecture at the IPM Institute in Tehran, called Model Theory, now becoming more geometric? The case of modularity.
Here are (very sketchy) notes for a minicourse called Model Theory of Abstract Elementary Classes: some recent trends. I gave that minicourse at the IPM in November 2015. The four two-hour sessions were:

Durante el Festschrift en honor a mi padre, José Luis Villaveces, en la Academia Colombiana de Ciencias Exactas, Físicas y Naturales, tuve el honor de dar una charla. Fue la primera vez que hablé sobre conexiones entre la teoría de modelos y la química, y lo hice de manera (en ese momento) muy tentativa. La charla se tituló ¿Existe una teoría de modelos de la química? (un diálogo, tres décadas – química y matemática).
De la charla salió también el artículo en un volumen de la Academia en 2017: ¿Hacia una teoría de modelos de la química?

For the Logic Seminar at the University of Turin in June 2015 I gave the lecture Categoricità, dalla teoria dei modelli alla teoria degli insiemi? (Categoricity, from Model Theory to Set Theory?)

During the Helsinki Model Theory Days (University of Helsinki, Mathematics Department) in May 2015 I gave the lecture Model Theory for Modular Invariants.

The Helsinki Collegium for Advanced Study invited me to give a lecture in the interdisciplinary meeting Getting There and Falling Short, where a number of art historians, linguists, mathematicians, philosophers, artists, etc. were invited to reflect on language’s ability of grasping concepts and its own shortcomings. My lecture (Grasping smoothly and letting go: categoricity and location) focused on categoricity and the problem of location.
