My research focuses on:
- the DNA methylome of the vascular system in atherosclerosis and in normal physiology
- changes in DNA methylation induced by lipoproteins
and specific lipids.
Collaborative work with Gertrud Lund (CINVESTAV Irapuato Unit, Mexico) aims to identify dietary factors that affect the epigenome during early life and adulthood.
I am a member of the International Programme for Collaboration and Research DOHaD, led by Dr. G. Barbosa-Sabanero (University of Guanajuato, Mexico) and Dr. F. Bolaños-Jiménez (University of Nantes, France).
Our group exploits a variety of tools including NGS, microarrays, genetically modified mice and drug design.
