Hi! I'm Gideon Koekoek. I have a Master's degree and a PhD in theoretical physics, both of which I obtained at the Vrije Universiteit Amsterdam, the Netherlands. During the last years of my studies I focused on theoretical cosmology, most notably temperature effects in the theory of cosmic inflation; this I did mostly at the Universiteit van Amsterdam (UvA). Right now I am stationed at Nikhef, the Dutch national institute for nuclear and high energy physics, where I do theoretical research in the field of gravitational waves emitted by binary systems. During working hours I enjoy my work, coffee, and discussing physics with my office mates. Teaching is also one of my passions. I have recently finished my PhD-thesis on a new and improved geodesic deviation method to describe motion in a curved spacetime and its application in calculating gravitational waves, and I am currently looking for a new position. I would enjoy a position in physics, for instance in (but not limited to) the field of gravitational waves, general relativity, and/or cosmology. I am also very interested in obtaining a teaching position in the field of physics, mathematics, or related. Finally, I would be very interested in a position that would allow me to use scientific knowledge and reasoning in practical applications.

Curriculum Vitae etc.
December 2011: been awarded the Jan Kluyver Prize, given annually by Nikhef for the PhD-thesis that best satisfies the following three criteria: 1. Clarity of the prÃ©cis; 2. Scientific quality of the underlying research; 3. Originality of the research method.
May 2011: finished PhD thesis: "Relativistic epicycles and gravitational waves", supervised by prof. dr. Jo van den Brand (Nikhef, VU) and prof.dr. Jan-Willem van Holten (Nikhef, Leiden University).
March 2011: paper "Geodesic deviations: modeling extreme mass-ratio systems and their gravitational waves" put on ArXiv; authored with Jan-Willem van Holten. It concerns the application of the geodesic deviation method to the extreme mass-ratio double star system and the production of gravitational waves. The paper can be found at: http://arxiv.org/abs/1103.5612 , and it is accepted for publication in CQG.
March 2011: the paper "Epicycles and Poincare Resonances in General Relativity" (for description: see below) published in Phys.Rev.D15, volume 83. issue 6.
November 2010: paper "Epicycles and Poincare Resonances in General Relativity" put on ArXiv; authored with Jan-Willem van Holten. It concerns a covariant and fully relativistic expansion series of geodesic motion in a general curved spacetime, with special emphasis on bound geodesic orbits in a Schwarzschild spacetime. The paper can be found at: http://arxiv.org/abs/1011.3973 .
April 2006-present: working on PhD research on gravitational waves emanating from binary systems, using a geodesic deviation approach in full Schwarzschild background; supervised by prof. dr. Jo van den Brand (VUA, Nikhef) and prof. dr. Jan-Willem van Holten (Leiden University, Nikhef; previously: VUA)
April 2006: received Masters degree in Theoretical Physics (Cum Laude), VUA
January 2006: finished Master thesis: "The warm inflation model", supervised by prof. dr. Jan Smit (UvA)
April 2004: finished literature study: "From Big Bang model to inflationary universe", supervised by prof. dr. Jan-Willem van Holten (Leiden University, Nikhef; previously: VUA).
May 2003: finished Bachelor thesis: "Classical solitary waves and solitons", supervised by prof. dr. Piet Mulders (VUA)
