Dr. Matero was born into a bicultural and bilingual family in Finland where he completed his primary education. He moved to the United States planning to pursue a career in physics but ended up studying both physics and theology. “Science alone was not satisfying to me, I experienced the ‘humanities suck’…what else does one do with such an undergraduate degree but go into medicine”, he comments. He completed medical school at Northwestern University and then moved to St. Louis and specialized in Emergency Medicine at Washington University. While there he developed an interest in Concussion- research and did some R and D work in this field as well. He was accepted to a faculty position at the University of Colorado School of Medicine in 2006. While the realm of MTBI continues to interest him, he has made and intentional move into the realm of education. He is currently the Associate Director of the 3rd year Medical Student CORE block in Emergency Medicine, the Emergency Medicine Intern Coordinator and is involved in resident education. Dr. Matero is most fascinated by questions regarding medical decision making and medical epistemology in particular with regard to the realm of Emergency Medicine.
