He has a passion for science and an extensive expertise in signaling and transcriptional regulation, in fields from developmental biology to immunology, and from pediatric cancer to Down syndrome research. Esteban majored in Molecular Biology back in Argentina and then moved to Spain to get a PhD in Biomedical Sciences. He received postdoctoral training for several years at the UMass Chan Medical School in Massachusetts before settling in Colorado. At a personal level, he enjoys (trail) running, hiking, and riding his bikes, whenever he is not spending time with his two buddies/sons.
