Research Interests

Broadly, my research focus is on pyrolysis of organic waste and biomass. I am currently interested in the development of new and/or improved thermochemical processes for biofuels and bioproducts. 

Specifically, we are now developing a carbon-negative pyrolysis system with autothermal operation. Operational tests are ongoing. We seek to further develop and scale-up this idea, ideally with an industry partner.

Simultaneously, I work in the development of integrated valorization approaches of various agricultural or animal residues via pyrolysis, and its integration with biomethane production.
I have also collaborated in the development of the Flash Carbonization technology developed by Professor Michael J. Antal at University of Hawai’i as a Visiting Scholar, and worked at Instituto de Carboquímica (Spanish National Research Council), both in postdoctoral positions
Previously to my PhD research, I also worked in gasification (fluidized bed and downdraft reactors) at demonstration scale
