Short Biography

I joined the dept. of Mechanical Engineering of Nazarbayev University in the summer of 2015. I hold a diploma of Naval Architecture & Marine Engineering from the National Technical University of Athens, Greece.  My Ph.D. in engineering is from the same institution. I have previously worked as a Research Associate in the school of Naval Architecture & Marine Engineering in the National Technical University, as a lecturer in the dept. of Naval Architecture, Technological & Education Institute of Athens and for the last year, before joining, served as an Assistant Professor at the Technological & Education Institute of Athens. I have actively participated in more than 18 EU and national funded research projects and I act as reviewer for several CAD/CAGD and Naval Architecture & marine Engineering journals

Short description: 

This research work focuses on the development of computational tools for optimizing the design of aeronautical and marine/maritime functional free-form surfaces, such as airfoils/hydrofoils, wings, blades, and propellers. As a common feature, the functionality of these products depends on their shape and even small variations of it may have significant impact on their performance. The goal of this proposal is to develop seamlessly integrated advanced tools for modeling and simulation, targeting the materialization of the design-through-analysis concept, which nowadays constitutes a prerequisite for efficient PLM (Product Lifecycle Management) in all industrial sectors producing highly-complex products.

Project’s main objectives list include the following:

  1. To establish new Boundary Element Method (BEM) tools for assessing the design of aeronautical and marine/maritime functional free-form surfaces (airfoils/hydrofoils, wind/tidal turbine blades and marine propellers) based on IsoGeometric Analysis (IGA).
  2. To achieve a seamless integration of Computer-Aided-Design (CAD) and numerical-simulation tools by exploiting NURBS and T-splines technology for the exact and low-cost representation of complex geometries.
  3. To establish an optimization framework that allows the automatic shape optimization of the geometric entities under investigation.
  4. To apply these tools in design, simulation, and optimization of functional free-form surfaces, which are of significance in aeronautical, shipbuilding and green energy technologies.
  5. To demonstrate the enhanced properties of the adopted approach through software prototypes for optimizing the performance of airfoils/hydrofoils, wind/tidal turbine blades and marine propellers.
