  My PhD adviser, at M.I.T, was Professor Byunghan Kim, who is an expert in the area of simple theories. A simple theory is a structure in which certain amalgamation
properties hold. You can find, here, some geometric pictures of 1-amalgamation and 3-amalgamation (1>2>3), used, particularly, in the second paper. My PhD thesis
was mainly concerned with developing properties of minimal structures in such theories. A minimal structure is, very roughly speaking, an abstract version of an algebraic
curve. Since then, I have been a research fellow at Edinburgh University, The University of Camerino and The University of Exeter, specialising in the geometry of
such curves.
