  • Conducted research related to enabling technologies to scale up processes dedicated to pollution prevention and clean energy production.
  • Successfully mounted and ran several customized bench and pilot-scale reactors involving slurries and solid suspensions. I also co-developed the process control of custom equipment.
  • Facilitated the activities of a research group comprising scientists of diverse backgrounds to meet challenging deadlines.
  • I also developed catalysts for performing heterogeneous Catalytic Wet Peroxide Oxidation to mineralize recalcitrant organic pollutants representing textile effluents.
  • I worked on my Ph.D. at University de Buenos Aires in Industrial Chemistry, oriented to the design and fluid dynamic characterization of reactors.
  • I was able to complement my basic science training with the assembly and operation of pilot-scale equipment, adding to my skills in designing non-invasive tomography experiments.
  • The application of industrial tomography techniques, such as Radioactive Particle Tracking (RPT) and gamma densitometry, is valuable for extracting macroscopic information from underlying flow regimes in conditions frequently encountered in many industrial processes difficult to obtain by other means due to complex rheology and opacity.
  • I used the tomographic data to validate simulations to describe multiphase flows.
  • I tested my data processing skills to verify models aimed at describing key processes for producing clean energy, such as biomass-based hydrogen and second-generation bioethanol.
  • As a docent, I was the first to conceive and teach green chemical engineering courses. Some of the classes are uploaded to my YouTube channel (so far, in Spanish only):
  • I also embraced the practical side of 3D-Printing beyond the production of amusing designs. My role in this context was as a supplier of a crucial part that otherwise would have been prohibitively expensive for a laboratory located in a developing country with scarce access to resources for research.
