I’m a Chilean Post-doctoral Scientist working on cell-based strategies for improving our understanding of heart development and regeneration under the supervision of Dr. Richard Harvey at The Victor Chang Cardiac Research Institute, Sydney, Australia. I completed my undergraduate research under Dr. Juan Larrain studying the developmental role of the Wnt-PCP pathway and Syndecan-4 in neural tube closure in 2013. Then, I concluded my Ph.D. working on tissue-resident fibro-adipogenic progenitor fate, plasticity, and heterogeneity in muscle and heart regeneration/repair in Dr. Enrique Brandan’s Lab with the co-supervision of Dr. Fabio Rossi at the University of British Columbia in 2019. I’ve been focused on comprehending myopathies and myogenic fate determination and differentiation in the context of fibrosis. My career goal is to advance our knowledge of the mechanisms regulating cellular plasticity, heterogeneity, and behavior. I point to a future where we will be able to translate that knowledge into efficient medical applications.
