Research Description
DNA damage arising from exposure to environmental toxins and cellular metabolites thwarts DNA replication and leads to genome instability, cell death, and diseases including cancer. Our laboratory uses the tools of structural biology and biochemistry to investigate molecular mechanisms of proteins involved in repairing DNA damage and maintaining replication fork progression. We primarily use X-ray crystallography as a starting point to understand how these proteins recognize and manipulate DNA structure to carry out their particular functions. Current work focuses on base excision repair of DNA alkylation damage by DNA glycosylases, repair of stalled replication forks by structure-specific DNA translocases, and the coordination of DNA unwinding and synthesis during eukaryotic replication. The long-term goals are to understand the fundamental processes underlying genome maintenance and to develop new therapeutic strategies that target genetic diseases.

Available Postdoctoral Position Details
Posted: 8/19/2016

Postdoctoral positions are available to study the structures and molecular mechanisms of proteins involved in progression and maintenance of eukaryotic DNA replication forks and repair of DNA alkylation damage. 

 A Ph.D. in biochemistry, biophysics, structural biology or related field and at least one first-author publication are required. Experience in X-ray crystallography, electron microscopy, and insect and mammalian cell expression systems is highly desirable.

To apply, please email CV, a cover letter describing why you are interested in the lab, reprints of recent publications, and names of 3 references to Brandt Eichman (
