'''Kees Joost Batenburg''',<br/>
a Dutch computer scientist and mathematician with M.Sc. degress in mathematics and CS, and Ph.D. in mathematics from [[Leiden University]],
researcher at [https://en.wikipedia.org/wiki/Centrum_Wiskunde_%26_Informatica Centrum Wiskunde & Informatica],
[https://en.wikipedia.org/wiki/Science_Park_Amsterdam Science Park Amsterdam],
[https://en.wikipedia.org/wiki/The_Netherlands The Netherlands],
and professor at Vision Lab, [https://en.wikipedia.org/wiki/University_of_Antwerp University of Antwerp],
[https://en.wikipedia.org/wiki/Wilrijk Wilrijk], [https://en.wikipedia.org/wiki/Belgium Belgium].
His research interests include [https://en.wikipedia.org/wiki/Discrete_tomography discrete]
and [https://en.wikipedia.org/wiki/Electron_tomography electron tomography],
[https://en.wikipedia.org/wiki/Combinatorial_optimization combinatorial optimization],
[[Genetic Programming#EvolutionaryAlgorithms|evolutionary algorithms]],
[[GPU|GPU computing]] for large-scale scientific computing, [https://en.wikipedia.org/wiki/Image_processing image processing],
[https://en.wikipedia.org/wiki/Computer_vision computer vision] and [https://en.wikipedia.org/wiki/Inverse_problem inverse problems].
He is member of the research team behind the ''Little Green Machine'' a [[GPU]] [https://en.wikipedia.org/wiki/Beowulf_cluster Beowulf cluster] <ref>[https://www.nwo.nl/en/research-and-results/research-projects/i/66/5966.html A Little Green Machine for High Performance Parallel Multipurpose Supercomputing Using Graphical Processing Units]</ref>,
and the [https://en.wikipedia.org/wiki/Fastra_II FASTRA II] desktop supercomputer designed for tomography.
=Nonograms=
Along with [[Walter Kosters]], Joost Batenburg researches on [[Nonogram|Nonograms]], picture logic puzzles where a pixel grid has to be filled with black and white pixels,
based on a description that indicates the lengths of the consecutive black segments for each row and column.
In this puzzle type, the numbers are a form of [https://en.wikipedia.org/wiki/Discrete_tomography discrete tomography]
that measures how many unbroken lines of filled-in squares there are in any given row or column.
While the Nonograms that can be found in puzzle books can typically be solved by applying a series of highly local reasoning steps regarding single rows and columns,
the general Nonogram problem is [https://en.wikipedia.org/wiki/NP-hard NP-hard].
