Graduate students in the Division meld molecular and structural biology with physical, organic and analytical chemistry to understand the molecular basis of biological processes and human disease. Research in the Biological Division focuses on the structure, stability and function of proteins, membranes, DNA, RNA, macromolecular complexes and viruses, natural product biogenesis, synthetic biology, and genomics.
Students are a constant source of new hypotheses for mechanisms underlying cellular machines like the ribosome, spliceosome, and as well as protein and RNA folding. Students tackle these problems using biochemical methods, chemical biosensor technologies, protein and nucleic acid crystallography, in vitro and in vivo evolution, multi-dimensional NMR spectroscopy, surface chemistry, atomic-force microscopy, fluorescence spectroscopy, and high-resolution mass spectrometry.
Doctoral students in our Divsion leave the Department broadly trained for leadership roles in academia and industry.
Recent Research Results
Interest in layered organohalide perovskites is motivated by their potential for use in optoelectronic devices. In these systems, the smallest and largest quantum wells are primarily concentrated near the glass and air interfaces of a film, thereby establishing a gradient in the average values of the bandgaps.
Chemistry Professor, Dorothy Erie, collaborates with researchers to conduct research on how proteins MutL and MutS prevent DNA replication errors by creating an immobile structure that calls more proteins to the site to repair the error
