Diego studied Mathematics at the Universities of Valladolid (2002) and Kaiserslautern (2003, double degree program). He obtained a PhD degree in Mathematics at the University of Valladolid in 2007. He was a postdoctoral researcher at the University of Kaiserslautern (2007) and a H.C. Ørsted postdoc fellow at the Technical University of Denmark (2008). He has been an assistant professor (2009-2012) and an associate professor (2013-2018) at Aalborg University. Diego has been a Ramón-y-Cajal fellow (2018-2023) and, since June 2023, he is an associate professor at IMUVA-Mathematics Research Institute, University of Valladolid.

Here (and also here) you can see me at AAECC-18 (Fortunately, I was not misbehaving at that moment).
And here another picture, this time not so blurred.

I am a member of the European (EMS) and Spanish (RSME) mathematical societies.
