Introduction
I am a Post-doctoral researcher at the University of Trento, Italy, in the Solid and Structural Mechanics Group of the Department of Civil, Environmental and Mechanical Engineering. In the past, from 2019 to 2022, I participated in the INSPIRE ITN project funded by the Horizon 2020 framework programme, for the purposes of obtaining my PhD in structural mechanics. In 2019 I got my Diploma in Naval Architecture and Marine Engineering from the National Technical University of Athens (NTUA).

With recent advances in variable-length structures for use in soft actuation, energy harvesting, energy dissipation and metamaterials, the mathematical modelling and numerical simulation of physical systems with time-varying domains is becoming increasingly important. The planar nonlinear dynamics of one-dimensional elastic structures with variable...
An elastic rod, straight in its undeformed state, has a mass attached at one end and a variable length, due to a constraint at the other end by a frictionless sliding sleeve. The constraint is arranged with the sliding direction parallel to a gravity field, in a way that the rod can freely slip inside of the sleeve, when the latter is not moving. I...
A highly deformable rod, modelled as the extensible elastica, is connected to a movable clamp at one end and to a pin sliding along a frictionless curved profile at the other. Bifurcation analysis shows that axial compliance provides a stabilizing effect in compression, but unstabilizing in tension. Moreover, with varying the constraint's curvature...

A biomimetic semi-activated oscillating-foil device with multiple foils in a parallel configuration is studied for the extraction of marine renewable energy. For the present investigation, an unsteady boundary element method (BEM) is used for the simulation of 3D lifting flows. For this work, the device is assumed to be submerged far from the free...
The propagation and transformation of water waves over varying bathymetries is a subject of fundamental interest to ocean, coastal and harbor engineers. The specific bathymetry considered in this paper consists of one or two, naturally formed or man-made, trenches. The problem we focus on is the transformation of an incoming solitary wave by the tr...
In the present work a biomimetic flappingfoil device is studied for the exploitation of marine renewable energy resources. For this purpose a GPU-accelerated Boundary Element Method (GPU-BEM), in its 3-dimensional version is developed. The lifting body is
submerged far from the free surface, neglecting the interaction with the additional boundary....
