I am Professor of Physical Oceanography in the School of Ocean Sciences, Bangor University which has been my base for many years. I am a seagoing Oceanographer with an enthusiasm for making new measurements to test theories and models but I also get involved in theoretical developments and enjoy the challenge of inter-disciplinary studies.

I have a broad range of interests in the physical processes that control I have a broad range of interests in the physical processes that control the environment in shelf seas and estuaries and their impact on biological and sediment processes in the water column. In particular, I have contributed to the study of 

(i) the interaction between buoyancy input and tidal stirring and the resulting tidal mixing fronts and 

(ii) the effects of freshwater input to estuaries and the shelf seas. Currently I am much involved with my research group in making innovative measurements of turbulent processes in the shelf seas and in lakes and using the results to test hypotheses and models of vertical mixing. I am also trying to apply understanding, acquired in the European shelf seas, to gain insight into the workings of other shelf sea regimes such as those in polar regions and in the tropics.
