Linda Randall is a Professor Emerita of Biochemistry and Wurdack Chair Emerita of Biological Chemistry at the University of Missouri.[1] Her research has shown unexpected and complex details of the movement of newly made proteins from the cytosol across membranes into the organelles of the cell.  In particular, she found that the entire protein was kept unfolded by association with a chaperone and not just directed to cross membranes by its terminal leader sequence.[2] In 1997, she was elected to the National Academy of Sciences of the USA because of the excellence of this work.  She has received a number of other honors and awards.[2]

Education

[edit]

Randall received her BS from Colorado State University in Zoology and her PhD at the University of Wisconsin in Molecular Biology.[1]

Academic research career

[edit]

Randall was a professor at the University of Uppsala for eight years before joining the faculty at Washington State University, WSU, in 1981.[3] After twenty years at WSU, she moved to the University of Missouri.[4]

Randall's research focuses on the mechanism of protein export in the bacterium Escherichia coli.[5] Her laboratory demonstrated the role of chaperones in the transport and folding of proteins.[2][5]
