Arnold graduated in Molecular Biology (2004, Comenius University in Bratislava, Slovakia). As an exchange student at Wageningen University and Research (WUR) in the Netherlands, he followed courses in bioinformatics and worked on his masters thesis in bioinformatics (Comparative genome analysis of White spot syndrome virus isolates).

He started his PhD research on comparative genomics of fungi and later focused on (phylogenetic) sequence-based clustering methods and data integration at the Laboratory of Bioinformatics, WUR (2009). In close collaboration with SURFsara, he used the Dutch Life Science Grid to compute a comprehensive matrix of corresponding genes (called orthologs) for all species with sequenced genomes. For this, he developed an efficient graph heuristics and an integrated protein resource.

As a postdoctoral researcher at the Department of Ecology and Evolution, University of Lausanne, Swiss Institute of Bioinformatics, he focused on genome-wide detection of positive selection in animal genomes using the Swiss Multi-science Computing Grid. Arnold returned to the Netherlands where he joined the Department of Genetics, Erasmus University Medical Center to study cellular effects of (non-)ionizing radiation using mass spectrometry-based proteomics.

In 2015 Arnold joined the team at the eScience Center. His interests include optimized (linked) data handing, analytics and/or efficient scientific workflows.
