Qualifications

September 2017 - October 2013

Awarded PhD in Geomatics, School of Engineering, Newcastle University, UK, “Morphology-based landslide monitoring system with a UAV”.

Aim: To investigate the potential of a consumer grade UAV system to provide accurate time series of 3D landslide information in the absence of physically established control points. A morphological-based strategy was developed applying surface morphological attributes in combination with the scale-invariant feature transform (SIFT) algorithm to generate pseudo control information and co-register multi-epoch UAV datasets for landslide monitoring.

Supervisors: Prof J.Mills, Prof P.Moore, Dr P.E.Miller (The James Hutton Institute) and J.E.Chambers (British Geological Survey).

Funding: This research was jointly funded by a Natural Environment Research Council (NERC) BGS BUFI award (S241) and an Engineering and Physical Sciences Research Council (EPSRC) DTA award (EP/L504828/1).

September 2013 - August 2011

School of Build Environment, Stockholm, Sweden. 
Thesis: “
Precision Analysis of 3D camera

Aim: To investigate calibration parameters of a Time of Flight camera and assess the output accuracy with benchmark observations. Rubin Prize winner for the best thesis in 2013.

October 2000 - July 2006

BSc/MSc (5-year Diploma) in Rural and Surveying Engineering, National “Metsovio” Technical University of Athens (NTUA), Greece.

Research

Research projects

May 2018 - Present

In collaboration with Dr Wen Xiao to the NERC-funded project Flood-PREPARED. The main activities are analysis and utilisation of CCTV and social media imagery for flood extraction and traffic monitoring, including the precise identification of flooded areas as well as detection and tracking of vehicle and pedestrian movements.
