Our research is at the interface of molecular biophysics, chemical biology, and synthetic biology. The group has two main intertwined goals: We want to understand how proteins fold and assemble into complex assemblies in their native cellular context, and to exploit the protein synthesis machinery to direct the construction of novel protein-based materials. In the long term, we hope to apply our discoveries to better understand protein-based human diseases and enable sustainable alternatives to plastics and other consumer materials.
Sydney Brenner asserted, "Progress in science depends on new techniques, new discoveries, and new ideas – probably in that order." In keeping with that spirit, to make progress on these challenging fronts, we synthesize new molecular probes, engineer new organisms, and develop new mass spec methods.
Protein Folding in vivo
We want to watch proteins inside cells to understand how physics and biology work together to build the world’s most proficient catalysts and molecular machines.
Cross-linking mass-spectrometry enables molecular interactions to be captured in situ. As an emerging tool, we develop new methods and molecules toward the goal of studying biophysical phenomena in living cells.
We are building a “loopable translator” which can iterate over mRNA sequences like a for loop in order to enable living assembly of programmable, hierarchical protein materials.
Novel Fibrous Proteins
Engineering and evolving new fibrous proteins to offer sustainable alternatives to plastics, concrete, and other consumer materials.
Recent News and Publications
We are grateful and excited that Hopkins is supporting our lab with its own orbitrap mass spectrometer!
Potential future graduate students interested in our projects will have the chance to learn more about our research group then.
