Peter Lammers is Research Professor in the School of Sustainable Engineering and the Built Environment at Arizona State University. Current funded research addresses renewable energy production with an emphasis on a mixotrophic extremophile known as Galdieria sulphuraria. A second focus area is  for mixotrophic wastewater treatment. Lammers is Principal Investigator for two Department of Energy awards: “Realization of Algae Potential” (2014-2016) and “A Novel Platform for Algal Biomass Production using Cellulosic Mixotrophy (2016-2018). Lammers is also the Chief Scientist for the Algae Testbed Public Private Partnership (ATP3). He serves as associate editor of the journal Algal Research.  Previous positions include Vice President for Biotechnology at Solix Biosystems (2009-2010), Research Professor at New Mexico State University (2010-2014) and Assistant, Associate, and Full Professor of Biochemistry at New Mexico State University (1985-2009).
