Professional biography

The smallest but most fun part of my job involves doing research on volcanoes. My research  allocation is 22 days per year (c.28% of a normal OU academic), all of which is spent doing fieldwork with my PhD students.

The largest part of my job is the Staff Tutor role, which roughly comprises three aspects: (1) managing a team of part-time tutors; (2) dealing with a multitude of student issues; (3) teaching.

I am employed by the Faculty of Science and I am based at the OU's National Centre in Edinburgh, Scotland.

 

Research Activity

My research uses volcanology to understand environmental and earth processes. I have a particular interest in exploring the growth and eruptive behaviour of volcanoes that were active during recent glacial periods, as this enables a better understanding of potential future eruption hazards.

Four current projects:

  1. Investigating little-known volcanoes. Projects are currently underway at Tindfjallajökull volcano (Iceland) and Volcán Quetrupillán (Chile). OU PhD project on Tindfjallajökull started September 2014.
  2. Explosive rhyolite eruption from Iceland's largest volcano to determine the cause(s) of explosivity and to determine the local impacts (e.g. flooding) and far-flung impacts (e.g. airspace closure due to ash clouds). OU PhD project started October 2013.
  3. Ar-Ar dating of subglacial volcanoes to provide information on thicknesses of Pleistocene ice sheets. (Manchester-OU PhD project started October 2012.)
  4. Volatile studies of subglacial rhyolites to better understand the mechanisms driving explosive eruptions (with collaborators at Lancaster University).

Other research highlights:

  1. I participated on a scientific expedition to the Grímsvötn crater just two months after the eruption ended.
  2. I was part of a team that carried out the first detailed study (including precise K-Ar dating) of a former ice-covered Icelandic central volcano (Askja).
  3. In June 2012 I walked into the Valley of Ten Thousand Smokes in Alaska exactly one century after start of the largest eruption of the 20th century occurred there.

Teaching interests

  • Line manager of 52 part-time teaching staff (Associate Lecturers).

  • Chair - S390 (Science Project Module). Level 3.

  • Overall responsibility for tutors and students on SXG390 (Geohazards). Level 3.

  • Chair (Award Board) - S339 Understanding the Continents. Level 3.

  • Sub-team lead, Earth & Environment

Impact and engagement

  1. Chair of IAVCEI Comission on Volcano-Ice Interaction.

  2. I was heavily involved in social (and conventional) media during the 2014-2015 Bárðarbunga volcano-seismic crisis which resulted in the largest eruption of lava in Iceland since the 1783 Laki eruption. My role was providing evidence-based scientific information to counter both media and scientific exaggerations.

  3. I was involved with the media during the 2010 Eyjafjallajökull and 2011 Grímsvötn eruptions.
