I completed my PhD at the University of Illinois at Urbana-Champaign in 2007 under the
supervision of Anand Pillay. The title of my thesis was Model Theory of Differentially
Closed Fields with Several Commuting Derivations. Currently, I am a postdoctoral fellow
at the National University of Colombia and a part of the Bogota Logic Group.

My research area is model theory of differential fields. I am mostly interested in questions
around Zil'ber's dichotomy, notions of rank in differential fields and differential galois theory.

Model Theory of Differentially Closed Fields with Several Commuting Derivations
My thesis. Contents are summarized in the introduction.

On Subgroups of the Additive Group in Differentially Closed Fields (submitted)
A publishable form of my thesis plus an application to differential algebra, answering
a question of Phyllis Cassidy.

The Group Defined by $\sigma(x)=\delta(x)$
Ongoing project. Trying to prove that the group defined by $\sigma(x)=\delta(x)$ in
an existentially closed difference-differential field is locally modular.
