Biography (Personal Interest): 

I grew up in Costa Rica surrounded by nature. Since my childhood, I have been very curious, especially with science related activities. During my bachelor program, I volunteered for three years for TECHO, which is a youth led non-profit organization in Latin America & the Caribbean. Through the collaborative work of families living in extreme poverty with youth volunteers, TECHO seeks to overcome poverty in slums. During this volunteer work, I had the chance to meet hundreds of families, and work together side by side as equal to make improvements to their communities. My volunteering experience helped shape my character to confront very difficult conditions and to value. Then, I got involved with several research projects that gave me the opportunity to get hands-on learning and research experiences. First, I collaborated on the update of Costa Rica biomass balance founded by the United Nations Environment Programme (UNEP). Through this project, we identified a large quantity of biomass resources that are available in different geographic zones, which at the same time contains high amounts of energy. Second, I got involved with the Center for Agricultural Research (CIA) at the University of Costa Rica (UCR). In this center, I was able to do research on anaerobic digestion, which I later used for my higher degree thesis called “Evaluation of biogas production by means of semicontinuous anaerobic biodigestion using coffee beneficiation residues as substrate.” Third, I contributed in the project DOS ECPA (Department of State Energy and Climate Partnership of the Americas) with Dr. Dana Kirk and Dr. Wei Liao from MSU. This project was a collaboration between the Departments of BAE of UCR and MSU. The goal of the project was identifying the potential and evaluating the feasibility of biomass energy operations in rural areas in Central America, such as solar bio-power systems.
