ARTURO JARAMILLO GIL

ABOUT ME

My name is Arturo Jaramillo Gil. Since September of 2018, I am a postdoctoral researcher in a collateral agreement between the universities of Luxembourg and Singapore. I work in collaboration with the research group of professors Ivan Nourdin, Giovanni Peccati, Adrian Roellin and Louis H.Y. Chen on topics of stochastic analysis and Stein's method.

In 2006, I studied my Bachelor in science, specialized in mathematics, at the University of Guanajuato (UG). My bachelor thesis advisor was professor Daniel Hernández and my thesis was oriented to the application of differential geometry and stochastic analysis in infinite dimensions, to the study of interest rates and bonds. In 2011, I started studying my master in science, specialized in probability and statistics at the Center of Research in Mathematics (CIMAT). My master thesis advisor was professor Juan Carlos Pardo Millán and my thesis consisted on the study of central and non-central limit theorems for multiple Skorohod integrals. In 2018 I obtained my PhD in mathematics at The University of Kansas (KU). While studying in KU, I conducted research on limit theorems and Malliavin calculus under the supervision of professor David Nualart.
