Current team members:

  • Pablo J. González (Senior Researcher)
  • Yu Jiang (COMET and University of Liverpool PhD researcher funded by CSC China Scholarship, 2017-2021). Yu works on the mechanics of continental normal faults applying satellite geodesy and bayesian inference methods.

In addition, we have enjoyed working with our lab visitors, and past team members.

Work with us:

The Estación Volcanológica de Canarias is a research group within CSIC, Spain’s largest research-intensive institution. CSIC is not an academic institution and does not award PhD degrees. However, we are able to supervise, e.g., early career researchers a) who are enrolled in Environmental and Earth Sciences PhD programs at Spanish universities, b) postdoctoral researchers (Marie Curie, Juan de la Cierva, etc), or c) otherwise self-funded researchers who want to spend time in Tenerife for a time-limited project.

If you are interested to collaborate, please contact me and come to research in Tenerife.
