Chris Petzold

Deputy Vice President of Technology and Director of Functional Genomics

Research Focus

Chris Petzold is a staff scientist with Berkeley Lab’s Biological Systems and Engineering Division. He obtained his Ph. D. in Chemistry from Purdue University with emphasis in gas-phase ion chemistry and mass spectrometric methods development. After graduating from Purdue, he performed his post-doctoral work at UC-Berkeley focusing on application of mass spectrometry to glycomics and lipidomics research. Chris joined Jay Keasling’s research group in 2005 as part of the team tasked to understand the impact of metabolic engineering on the host microbe via systems biology.

As director of JBEI’s Functional Genomics Research Group, his focus is on developing mass spectrometric solutions to problems facing biofuel production. Recent work has focused on applying quantitative proteomics to metabolic engineering efforts. This work furthers rational design and optimization of novel metabolic pathways for a wide variety applications.

Projects

  • Develop targeted and shotgun proteomics methods for biofuel-producing hosts
  • Integrate analytical technologies with the metabolic engineering Design-Build-Test-Learn cycle
  • Apply proteomic methods to help reach JBEI research goals
