Can we directly measure the local distribution of Dark Matter from - PowerPoint PPT Presentation

Can we directly measure the local distribution of Dark Matter from Earth? Bradley J Kavanagh GRAPPA, University of Amsterdam 17th October 2018 PRISMA Colloquium, Mainz b.j.kavanagh@uva.nl @BradleyKavanagh

Undergraduate (2007-2011): University of Cambridge, UK Studied: Everything from organic chemistry to crystallography

PhD (2011-2014): University of Nottingham, UK Thesis Title: “Confronting astrophysical uncertainties in the direct detection of dark matter” 
 (2014, Supervised by Anne M. Green)

Postdoc #1 (2014-2017): IPhT & LPTHE, Paris, France Spent time worrying about: More ‘particle’ aspects of Dark Matter - how does it interact with nuclei? 
 (Supervised by Marco Cirelli)

Postdoc #2 (2017-): GRAPPA, University of Amsterdam People keep asking me about: Dark Matter, primordial black holes, gravitational waves, neutrinos,… 
 (Supervised by Gianfranco Bertone)

Open Science Papers (and talks) are just propaganda… …research is notes, calculations, data, code . The more we share, the easier life gets for everyone. Plenty of tools to facilitate sharing and collaboration: Aiming in the last few years to share as much as possible. Not always successful. But every small step is a step in the right direction. bradkav.net github.com/bradkav
