Our lab studies the atomic structure of proteins using experimental and computational approaches. Our primary experimental tool is X-ray crystallography. We apply our knowledge of structure to help design drugs, deepen understanding of protein structure and function, and address fundamental questions of protein engineering, stability, and solubility. Our lab also develops new techniques for the analysis of X-ray crystallographic data. We are one of the largest research labs at the University of Hawaii.
Congratulations to Michelle for taking first place in the Sciences for her presentation at the campus-wide UROP symposium! She is the second student from our lab to have received this honor.
