Dr Craig Marshall

Senior Lecturer, Department of Biochemistry

Dr Craig MarshallCraig's research is focused on cold adaptations; specifically, organisms that live in cold places. Most of the world's organisms tolerate freeze-thaw cycles—some freeze, others super cool; all have strategies to cope with sub-zero temperatures.

In particular, Craig's work centres on:

  • What pathways are important in cold tolerance?
  • How do proteins protect against freezing or ice damage?
  • How do enzymes function at low temperatures?
  • What other factors cause stress at low temperatures?

Craig's work also involves identifying proteins important in ice formation, and in identifying genes that are associated with freezing and thawing in an Antarctic nematode, Panagrolaimus davidi.
