• Physical Oceanography PhD (Gothenburg University) PhD

I graduated in Physical Oceanography from Gothenburg University in 1999 and undertook my PhD in physical oceanography at the same university between 2008-2004. I stayed in Gothenburg as a research associate for a further year before moving to Bangor to start as a post-doctoral researcher on the structure of turbulence in shelf seas.  In 2008 I was awarded a NERC Advanced Fellowship investigating the effects of sea-level change on the dissipation of tidal energy in the past, present and future and how that may impact on climate. In 2013 Bangor offered me position as Senior Lecturer in Physical Oceanography, and in 2016 I was promoted to Reader.

I am a physical oceanographer using models and observations to explore how the tides interact with other components of the Earth system and how these interactions change over long timescales. I especially focus on how tidally driven mixing influence large-scale ocean circulation and climate; effects of sea-level change (on short time scales) and continental drift (on geological time scales) on the tides; ice-ocean-climate interactions and how melting ice-sheets will affect the earth system; the influence of the tides to allow the ocean to evolve and host life, including tidal dynamics during extinction events.  

 teach physical oceanography, numerical methods, and dynamics, with focus on masters level.

I have been lead supervisor for 3 PhD students to completion, and co-supervised a further 2. Currently, I am leading 4 PhDs and co-supervising a further 4:
