Presentation

I am a chemical engineer with a strong background in bioenergy. My research focuses on the analysis of different biomass residues streams to harness them for energy production, value-added products or fertilizer, exploring their various applications and uses. Over the years, I have worked across different areas, with a primary focus on anaerobic digestion for biogas production. Initially, my research involved traditional substrates such as cattle and swine manure, later expanding to dedicated energy crops and now I am exploring the potential of crop residues and agro-industry by-products and co-products, pivoting my research between biorefineries, circular economy, sustainable low-carbon production, sistems analysis, among others.

I believe that there are different options for the use of residual biomass, whether for the production of biogas or for the production of value-added products, this depends on the context, process economics, sustainability, legislation among others. In some cases, converting residual biomass only into biogas may not be the most suitable option, highlighting the need for a tailored approach to maximize its potential for integration into biorefinery schemes.

I am also deeply interested in working with rural communities in the Andean and Amazonian regions to explore opportunities for emissions trading and offsetting through the development of models for the proper utilization of livestock waste and agricultural residues, with a focus on biogas production. My previous experience outside the academic and scientific fields allows me to combine scientific research with practical applications, bridging the gap between theory and aplication for real-world problem-solving.

Cooperation

We currently have close collaboration with the Biogas Solutions Research Center, Sweden (BSRC) and Linköping University (LIU) to develop research related to the sustainable use of residual flows from agricultural production and their integration into biorefinery schemes, as well as the possibility of using intermediate crops in biogas production with a focus on systems analysis.

Throughout my research career, I have built strong collaboration networks including the Federal University of Itajuba (NEST Reseach group), Technical University of Denmark (BioConversion Research group), Peruvian Amazon Research Institute, La Molina National Agrarian University (Renewable Energy Laboratory), San Cristobal de Huamanga National University, Federal University of Uberlandia, These collaborations have facilitated joint research efforts, knowledge exchange, and interdisciplinary projects at various stages.

Background

  • PhD in Bionergy. Federal University of Uberlândia, Brazil
  • MsC in Energy Engineering. Federal University of Itajubá, Brazil
  • Chemical Engineer. National University of San Cristóbal de Huamanga, Peru

Before transitioning into the scientific and academic field, I worked with international technical cooperation organizations. At the Netherlands Development Organization (SNV), I served as an advisor for rural development projects, promoting biogas solutions in isolated communities of the Amazon. I also collaborated with Practical Action and Green Empowerment as a renewable energy specialist and consultant, conducting studies on alternative uses of wastewater from the coffee industry through anaerobic digestion and developing small-scale energy programs along the Peruvian coast. Additionally, I have hands-on experience in the construction and installation of household and medium-scale biodigesters (tropical biodigesters). 

Former volunteer: Caritas Denmark, Center of excellence in rehabilitation and oriented work Brazil, COVID-19 volunteers Brazil.
