Curriculum vitae

Gustavo Adolfo Ken Arroyo Ohori was born on June 12, 1985 in Mexico City. He graduated in 2003 from the Bicultural High School (‘Preparatoria Bicultural’) programme and in 2007 from the BSc in Computer Science and Technology programme (‘ITC01: Ingeniería en Tecnologías Computacionales’) at the Mexico City campus of the Monterrey Institute of Technology and Higher Education (‘Instituto Tecnológico y de Estudios Superiores de Monterrey’).

Arriving to the Delft University of Technology in 2008, Ken graduated from the MSc in Geomatics programme in 2010 with his thesis on the Validation and automatic repair of planar partitions using a constrained triangulation, which later evolved into some of the data repair ideas exposed in Chapter 10 of this thesis.

In 2011, Ken started his PhD project on the Higher-dimensional modelling of geographic information, supervised by Jantien Stoter and Hugo Ledoux, working under the umbrella of the project 5D Data Modelling: Full Integration of 2D/3D Space, Time and Scale Dimensions of the Dutch Technology Foundation (STW). In October 2012, he visited Guillaume Damiand, collaborating on the incremental construction method that later became Chapter 7 of this thesis.

In 2016, Ken started working as a postdoc in the same 5D Data Modelling project, focusing on 4D visualisation and in the integrated modelling of space and time.
