Personal profile
Short bio
Experienced chemical engineer with a Ph.D. and 15+ years of R&D experience in green chemistry, sustainable materials, and cutting-edge manufacturing processes (dry jet-wet spinning, hollow fibers, 3D printing). Skilled in nanomaterials characterization (certified at top-tier institutions, including Aalto University, Stanford, and UC Berkeley) and industrial processes including work in cellulose biotechnology (Rubi Laboratories, Stanford, California)). Recognized for contributions to lignocellulose waste regeneration and carbon capture and utilization strategies, with a track record of successful project management, five inventions, and supervision of six graduate students' theses. Academic experience includes serving as a professor, researcher, executive manager, and founder of the Chemical Engineering program at the University of Bío-Bío(Chile), and R&D experience in the ceramic industry(Colombia). Published over 25 papers in top-tier journals such as Advanced Materials and collaborated with over 40 researchers, professors, and engineers on multidisciplinary academy/industry projects with institutions such as Aalto University, Living Sea Sculpture, Eastman Chemical Company, Futamura, University of Bío-Bío, and The University of British Columbia. I am passionate about making a positive impact on the industry of sustainable and functional materials and excited to apply my skills and expertise to new challenges.
