Dany Vohl

Thank you for landing on my personal research site. If you do not readily know me, here is a brief introduction to myself and my academic background.

I am a Canadian researcher operating in the fields of astronomy and astrophysics. I grew up in Québec, Canada. Hence, my mother tongue is French, and I am Québécois. I hold a MSc degree by research in Computer Science from Université Laval (A/Prof Danny Dubé, Prof Laurent Drissen), Quebec City, Canada, and a PhD degree by research in astronomy completed at the Centre from Astrophysics and Supercomputing, Swinburne University of Technology (Prof Christopher J. Fluke, and co-supervision of A/Prof David G. Barnes [Monash University], and Dr Amr H. Hassan) in Melbourne, Australia. Links to my theses are listed in the work section.

I currently work at the Anton Pannekoek Institute for Astronomy at the University of Amsterdam (UvA) and ASTRON, the Netherlands Institute for Radioastronomy with Prof. Jason Hessels (UvA / ASTRON) and A/Prof Harish Vedantham (University of Groningen / ASTRON) on searching for compact radio sources in the International Low-Frequency Array (LOFAR) LoTSS survey. I previously worked at the Netherland Institute for Radio Astronomy (ASTRON) on data processing and analysis of the ALERT survey (Joeri van Leeuwen, ASTRON / UvA), searching (and finding!) for Fast Radio Bursts with the Westerbork Synthesis Radio Telescope and LOFAR, both located in the Netherlands.

A curated list of scientific articles and related publications I have either written or co-authored can be found under the work section. For each item listed, a link to the publication is included. A similar (possibly more up-to-date) list can be found via the astrophysics data system.

Academia provides the opportunity to present our work at different conferences around the world. A list of my previous presentations is included on this site.

Finally, a core part of my work has involved software development, and sometimes software training. A list of projects I worked on in the past years, along with software releases, can also be found in the following section.

In the hope that this page can be useful to some of you.
