Olgica Bakajin is the CEO and Founder of Porifera Inc., a San Leandro, California-based company pioneering forward osmosis membrane technology for the food, beverage, and industrial water sectors. A physicist by training - B.A. from the University of Chicago and Ph.D. from Princeton - she spent nearly a decade at Lawrence Livermore National Laboratory developing carbon nanotube membranes that move water 1,000x faster than conventional materials. Her 2006 Science paper on carbon nanotube desalination became the most-cited chemistry article in the journal. In 2009 she spun Porifera out of LLNL, and the company now serves 100+ customers across 20+ countries, helping breweries, coffee roasters, and winemakers concentrate their products without heat, preserving flavor, aroma, and nutrients while slashing energy use by up to 80%.
