David Mulder completed his Ph.D. in Biochemistry in 2010 from Montana State University after receiving a B.S. in Chemistry at Calvin College in 2005. At Montana State under Professor John Peters, his research revolved around structure-function studies of metalloenzymes, specifically investigating the maturation of [FeFe]-hydrogenases.

Dr. Mulder's main thesis work involved utilizing a wide array of biophysical techniques and x-ray crystallography to characterize an intermediate form of green algae hydrogenase, which shed light on the mechanism of [FeFe]-hydrogenase activation along with basic principles as to how complex metal clusters in general assemble in nature. At NREL, his current research includes developing a high-throughput screen with the goal of identifying oxygen-tolerant bacterial hydrogenases. These studies use ongoing structural studies as an approach to identify basic and specific properties of hydrogenases vital toward improving the enzyme's overall tolerance to oxygen.
