Jens E. d’Hondt

Hi there! I’m Jens, a Postdoctoral Scientist at the Barcelona Supercomputing Center. I recently graduated with a PhD from the Database group at the Department of Mathematics and Computer Science at TU Eindhoven.

My research interests are twofold. Currently, I am working on super-resolution models for upscaling atmospheric simulations, with a focus on physics-based neural networks and ML-based simulation emulators. Previously, my doctoral work focused on the design and implementation of efficient algorithms for multivariate similarity search, particularly in the context of high-dimensional data. This involved detection of high-order relationships in large databases, as well as the design of efficient algorithms for similarity search on multivariate data.

Some recent projects I have been working on include:

  • Super-resolution models for upscaling atmospheric simulations using physics-based neural networks and ML-based simulation emulators;
  • Fast detection of high-order relationships in large databases (Correlation Detective library) [1], [2], [3], [4];
  • Efficient similarity search on multivariate data [5];
  • Large-scale evaluations of distance measures for multivariate data [6], [7];

Please feel free to reach out to me if you have any questions or would like to discuss any of my work. I am always open to new collaborations and opportunities.

You can find my CV here.
