Dr Memos’s research interests include conventional and probabilistic water wave mechanics, port structures behaviour under seismic action, wave interaction with submerged coastal structures. He has conducted an array of basic and applied research projects on these and related topics and led extensive physical and mathematical modelling projects in research centres such as Wallingford, UK; CEDEX, Spain; Imperial College, UK; NTUA, Greece; TUDelft, the Netherlands. He directed 25 funded fundamental or applied research projects in such topics as those mentioned below, while in 5 more he was member of the research team.

Internally funded or sponsored research areas include:

• The formation of bores
• Diffraction of water waves
• Optimization of port storage capacity
• Wind-wave interactions & wave statistics
• Wave transformations in shallow water
• Theoretical and experimental investigation of the interaction between surface and underground waters
• Stochastic representation of sea waves in shallow waters
• Environmental design of coastal works
• Stochastic beach dynamics in the lee of submerged breakwaters
• Nonlinear Boussinesq–type wave models
• Kinematics inside porous submerged breakwaters.
