Data-derived Search Strategies
I'm a particle physicists and work since begin 2006 for the ATLAS experiment at CERN (Geneva). I was a member of
the DØ experiment at Fermilab (Chicago) between 2004 and 2006
and a member of the
H1 experiment at DESY (in Hamburg) between 1998 and 2004.
My research objective is the discovery of a signal of physics
beyond our current theory of the microscopic world (the so called Standard Model).
Select some of the research topics from the menu bar.
- A complete list of my papers (also with ATLAS, D0 and H1) can be found :
- My Outreach work and some review articles
- Interested in really old stuff? My Ph.D. thesis and diploma thesis at the RWTH Aachen can be found here.
- For those even more interested in my physics life: An ultrashort CV
RESEARCH: ATLAS EXPERIMENT
This is a collection of work that I am doing in ATLAS (including some links to notes, papers and relevant webpages):
Monte Carlo studies, Data analysis, software, trigger, upgrade activities:
RESEARCH: DATA SCIENCE & MACHINE LEARNING IN PARTICLE PHYSICS
I work on the following topics:
- A database for high-parameteric data in the fields of Astro and Particlephysic : Prototype at idarksurvey
(based on SPOT developed with the Dutch escience center)
- Using Machine Learning and advanced data analysis to identify the nature of Dark Matter. We initated the worldwide first workshop and build a community. Go to
- The the idark project with the Dutch escience center
- The BSM-AI project to use machine learning to learn the global model-data: susy-ai & bsm-ai
- The ASTRO-AI projec to use ConvNets for Astrophysics, a first paper is : ConvNets for gamma-rays
- Data-derived searches for New Physics and search algorithms:
