Alarcon, Emilio

Dr. Emilio I. Alarcon is a Scientist in the Division of Cardiac Surgery and Director of the Bio-nanomaterials Chemistry and Engineering Laboratory at the University of Ottawa Heart Institute. He is also an Associate Professor in the Department of Biochemistry, Microbiology and Immunology at the University of Ottawa.


Dr. Alarcon was born in Santiago, Chile. In 2005, he received his B.Sc. in Chemistry under the supervision of Professor Eduardo Lissi at Universidad de Santiago de Chile exploring the chemiluminescent mechanisms of tryptophan oxidation. Shortly thereafter, Dr. Alarcon moved to Pontificia Universidad Catolica de Chile to pursue graduate studies. He received his MSc in Chemistry in 2008 and one year later the degree of PhD in Chemistry with a dissertation on Oxidation mechanisms of proteins mediated by reactive oxygen species. The same year Dr. Alarcon moved to Ottawa with his family for a postdoctoral position at Dr. Tito Scaiano’s laboratory, at the University of Ottawa, where he explored the development of new bionanomaterials for the health sciences and biosensors. In 2011 Dr. Alarcon was promoted to Research Associate that he held until he moved to the University of Ottawa Heart Institute in July 2014. He has published over 83 articles in peer-reviewed journals, several book chapters, and edited two books on regenerative medicine and nanomaterials

Dr. Alarcon is an Associate Editor for Journal Frontiers in Biomaterials. He has been a reviewer for over 450 papers in a number of Scientific Journals.

His laboratory is currently funded by a Natural Sciences and Engineering Research Council of Canada (NSERC) Discovery grant, Canadian Institutes of Health Research (CIHR) program grant,  NSERC Collaborative Health Research Projects (CHRP) grant, the New Frontiers Research Fund, and the Government of Ontario.

Research and clinical interests

Our research is focused on the fabrication, development and implementation of new materials with regenerative capabilities for tissue regeneration of heart, skin, and soft tissues.
