Research Interests

Research focus includes:

  1. Current and past freshwater contributions into the Antarctic Ocean and effects on ocean circulation (the first results from this research were recently published by Nature Geoscience and EPSL).
  2. Climate influences on Northern Europe and effects on migration and endemism.
  3. Climate-driven human evolution, innovation, and dispersal through Africa.
  4. Major climatic boundary thresholds through geological time.
  5. Understanding biogeochemical cycling using isotope techniques.
  6. Development of stable isotope techniques in relation to current environmental issues.
  7. Developing research within the International Continental scientific Drilling Program (since UK became a member in April 2012): Lake Ohrid (UK-PI), Lake Challa (Co-I), Hominin evolution (Co-I), Mochras and Tanzania (Co-I). The broad themes that these projects address are climate influences on the Earth and its inhabitants through geological time.
