Division Director

Lance C. Seefeldt is Professor of Chemistry and Biochemistry at Utah State University.  He received his PhD in Biochemistry from the University of California at Riverside and was a Postdoctoral Fellow in the Center for Metalloenzyme Studies at the University of Georgia.  He joined the faculty at Utah State University in 1993.  He is the recipient of the D. Wynne Thorne Research Award and is a Fellow of the American Association for the Advancement of Science.  He is the Utah State University Institutional PI and lead of the Microbial Media and Feedstock Division of CUBES.

Dr. Seefeldt’s research focus is on biological nitrogen fixation.  He has been investigating the mechanism of activation of N2 by the bacterial enzyme nitrogenase.  This work has recently lead to the insight that metal-hydrides are central to the reduction of N2 to NH3.  He is also investigating how to grow nitrogen fixing bacteria with electrodes as a way to accomplish light-driven reduction of N2 and CO2 as a way to capture and make available these resources from the Martian atmosphere.

Postdoctoral Scholar

Artavazd Badalyan received a Diploma in chemistry from the Lomonosov Moscow State University in Russia and a Ph.D. in analytical biochemistry in the group of Prof. Ulla Wollenberger from the University of Potsdam in Germany where he focused on the bioelectrochemistry of molybdenum hydroxylases and on the development of electrochemical biosensors. He was a postdoctoral research associate with Prof. Shannon Stahl at the Department of Chemistry at the University of Wisconsin-Madison in the field of organic electrochemistry where he developed a novel bioinspired electrocatalyst system for the low-potential alcohol oxidation. Following a position at the Draegerwerk AG as a project leader in the field of electrochemical sensors, he joined the group of Prof. Lance Seefeldt at the Department of Chemistry and Biochemistry at the Utah State University and works on the (bio)electrocatalysis for nitrogen fixation.

Yuexiao Shen joined Prof. Peidong Yang’s group at UC Berkeley as a postdoc in October, 2017. He finished his Ph.D. from the department of Chemical Engineering at Penn State in 2016. During his Ph.D., he worked on several projects in the interdisciplinary areas of chemical engineering, biology, chemistry and material science. He was focused on developing bioinspired membranes using membrane proteins that mimic the rapid and selective transport as seen in biological membranes. He extended to explore the potential of mimicking biological channels and lipids using supramolecular chemistry and investigating them using biophysical techniques. Yuexiao finished his bachelor and master degrees at Tsinghua University, where he studied environmental engineering. His academic accomplishments include several high-quality publications in journals such as PNAS, JACS and Journal of Membrane Science (JMS), and have been recognized by nationwide academic organizations with a number of very competitive awards. Yuexiao has already been offered an assistant professor position at Department of Civil, Environmental, and Construction Engineering at Texas Tech.

Graduate Student

Anthony Abel is a Ph.D. student in Chemical Engineering in the Clark Laboratory at UC Berkeley. Previously, he earned his B.S. in Chemical Engineering and M.S. in Materials Science at Drexel University in Philadelphia, PA, where he developed solution deposition techniques for inexpensive semiconductor materials. He has previously worked for the National Renewable Energy Laboratory, where he designed reactors for the sustainable production of hydrogen via photoelectrochemical water splitting. 

Anthony’s research interests lie at the intersection of chemical engineering, materials science, and microbial synthesis. Within CUBES, he will focus on the simulation and design of hybrid bioinorganic reactors and engineering microbes to function optimally within this artificial environment.

In his spare time, Anthony is a mentor for Bay Area Graduate Pathways to STEM, and enjoys reading science fiction and playing squash.

Stefano Cestellos-Blanco is a Ph.D. student in Materials Science & Engineering in the Yang Group under the direction of Professor Peidong Yang at the University of California, Berkeley. He received his B.S. degree in Chemical Engineering from Stanford University in 2016. His research interests lie at the intersection of inorganic materials and molecular biology. He envisions a future in which nanoengineered materials work in cooperation with the natural world. Stefano is investigating biohybrid catalytic systems for the fixation and utilization of CO2 and N2 in the MMFD division of CUBES. 

Ji Min Kim is a 1st year Ph.D. student in Materials Science and Engineering at the University of California Berkeley in the Yang Group. She received her B.S. degree in Materials Science and Engineering from Hanyang University in 2016 and M.S. degree in Materials Science and Engineering from Seoul National University in 2018. Her research interest is focused on the CO2 fixation via a semiconductor nanowire-bacteria hybrid system in the MMFD division of CUBES. The system utilizing light capturing high surface area nanowire array and acetogenic anaerobes enables the photoelectrochemical acetic acid production with long-term stability.

Hao Zhang is a 4th year graduate student in Chemistry at University of California Berkeley with Prof. Peidong Yang. She received her B.S in Material Science and Engineering from University of Science and Technology of China (USTC) in 2014.
Her research is focused on the CO2 fixation via photosynthetic biohybrid systems(PBSs) in the MMFD division. The non-photosynthetic bacteria could be photosensitized by using the semiconductors to reduce the CO2 into multicarbon products, such as acetate, ethanol, and other valuable products. Such PBSs inherits both the high light-harvesting efficiency and the superior catalytic performance from solid-state semiconductors and whole-cell microorganisms, respectively.


Currently Su is a postdoctoral researcher working with Professor Peidong Yang at University of California, Berkeley. His current research focuses on the bioelectrochemical CO2 fixation and N2 reduction. He received his Ph.D. degree in Chemistry on September 2017, with Professor Peidong Yang at University of California, Berkeley. During the Ph.D., he was awarded the MRS Graduate Student Award and the Chinese Government Award for Outstanding Self-financed Student Abroad.
