President & Chief Technology Officer

  • Oversees all technical operations, research and development at Pajarito Powder
  • Represents the company externally by promoting our latest research and by developing relationships with partner organizations.

Dr. Barr Zulevi has extensive experience in materials science, both from his academic career and commercialization experience since co-founding Pajarito Powder in 2012. Dr. Zulevi has overseen and led the Pajarito Powder team in developing the world-class VariPoreTM manufacturing platform and VariPoreTM line of Engineered Catalysts and Catalysts Supports. Under his leadership, Pajarito Powder has licensed, scaled-up, and re-engineered catalytically relevant materials, including catalyst technologies from Los Alamos National Laboratories, University of New Mexico, INRS, and Northeastern University. A team of scientists and technicians supports him with extensive expertise in developing catalysts, technology-transfer, scale-up, and manufacturing of electrocatalysts for fuel cell and electrolyzer applications.
