Hometown: Concepción, Chile
Education: B.Sc. Marine Biology 2003, University of Concepcion (Chile); Diploma in Environmental Analysis and Management 2004, University of Concepcion (Chile); PhD 2009 University of Concepcion (Chile)
I graduated as a Marine Biologist in the University of Concepcion, where I also received my PhD in Environmental Sciences on 2010. I have been interested principally in native fish reproduction biology and the effects of industrial wastewater on it.
Since 2006, I have participated in several studies related the effects of pulp and paper mill effluents in across Chilean freshwater basins and in coastal waters with issues related to oil spills. In fish populations, I have worked in a series of responses such as fish condition, growth, alterations of gonad size and increases in liver size that can result in changes at a reproductive level on sexual maturity and fecundity.
I have been working trying to fill the gap in basic biological data of Chilean native ichtyofauna collecting reproductive (steroid hormones, gonad histology, ovarian size, length frequency) and metabolic data (condition, liver size, metabolic activity) describing natural variability in the two most abundant freshwater species Bagre (Trichomycterus areolatus) and Carmelita (Percilia gillissi) and in coastal fish species as the redspotted catshark (Schroederichthys chilensis).
As a graduate student in EULA Centre for Environmental Sciences I have collaborated with Canadian Rivers Institute since 2006 working with Dr Kelly Munkittrick and with Environment Canada collaborating with Dr Mark McMaster.
During my graduate studies I have been recipient of awards from Foreign Affairs Canada under the Graduate Student Exchange Program, under the theme of Canada-Chile Leadership Exchange Scholarships, INNOVA Biobio graduate student Award for Innovative Thesis and Graduate Exchange award from the Chilean Embassy in Italy, spending also 2 month of research at University of Siena, Italy.
