Education and academic training:

• 2019, Alexander von Humboldt Fellow, Institute of Coastal Research, Helmholtz-Zentrum Hereon, Germany.

• 2013 - 2014, Postdoc, Dept. of Atmospheric and Oceanic Sciences, University of California, Los Angeles, USA.

• 2013: David Crighton Fellow, Dept. of Applied Mathematics and Theoretical Physics, University of Cambridge, UK.

I am a Senior Lecturer (Associate Professor) in the School of Science and Engineering at the University of Dundee. My research is primarily curiosity-driven; I typically formulate reduced-order physical and mathematical models of various problems encountered in fluid dynamics, especially pertaining to geophysical and environmental flows. Some of my talks/lectures are available on Youtube: GFD Lecture-1, GFD Lecture-2, Synchronization and Instability and Hamiltonian fluid dynamics.
