I am a research professor (ZAP-BOF) in elementary particle physics at the Vrije Universiteit Brussel, working at the Interuniversity Institute for High Energies - IIHE (ULB-VUB). We are trying to experimentally answer questions like: how did the universe evolve? What are the smallest constituents of matter and are they really the smallest? What is the nature of space and time? What, really, is mass?

My research interests include the search for signs of new physics using the large hadron collider at CERN. My focus is on detection of new physics, such as for example Super-Symmetry (SUSY), using precision measurements and direct searches, focusing on the top quark sector. I work in the Compact Muon Solenoid (CMS) collaboration, where I am active in top quark physics and the search for new particles that decay to top quarks. I have been responsible for leadership of many research teams at CERN and CMS, the most prominent probably the start of the Beyond-Two-Generations (B2G) physics group, a physics coordination group dedicated to searches in the top quark sector in the CMS experiment. 

In 2013, I was actively involved with the LHC Physics Center at Fermilab as a LPC distinguished researcher.

I regularly use social media, so take a look at my twitter feed freyablekman and follow me if you like.

One only really understands physics when one can explain it to the barmaid in the local pub

[Ernest Rutherford (1871-1937)]

The explanation of the concepts of basic research to non-experts is usually referred to as outreach. Nowadays, with the dwindling number of students choosing scientific subjects is in sharp contrast with the demand of scientists in all different roles of society (so not only to work at universities or research labs like CERN). Science is considered either hard, or boring or both. This is particularly interesting as the jobs that scientists hold are typically not boring at all, these are some of the more wanted jobs society but some way or another this concept is not conveyed to high school students when they choose or plan their future.

 

At CERN I've been active in the CMS outreach committee, and am a certified CERN and CMS guide. One of my contributions was the Dutch version of the CMS brochure. The CMS brochure is aimed at advanced high school students, and explains in two pages what CMS is trying to measure, why this is interesting and also relevant for people who are not directly contributing to basic particle physics research. 

Some recent appearances 

My outreach heavily focuses on using social media and modern media outlets. You can follow me on twitter with handle freyablekman.

Other social media

I am also part of a select group of CERN physicists that answer questions on twitter. Use hash tag #askCERN to @CERN or just directly to @freyablekman
In March 2016 I curated the twitter account @_moriond_ of the famous particle physics conference Rencontres De Moriond

Recent videos

 

I was one of the scientists featured at CERN during a extremely successfull youtube video series on the restart of the large hadron collider in 2015. 

I was one for the organisers and interviewed when the Belgian-Dutch technology website tweakers.net visited CERN and reported this in a three-part youtube documentary.

Blogs

During the LHC startup in 2008-2009, I made some blogging attempts:

The Higgs blog which accompanied the excellent Higgs documentary for which I was one of the scientists who contributed 
The Quantum Diaries blog effort

Experimental Physics / Experimentele fysica

This is the obligatory experimental physics laboratory for students in the first year of the bachelor Physics and Astronomy. The teaching language is Dutch. More course information can be found here.

Simulation of Physics Phenomena and Detectors in Modern Physics

This elective course is particularly suited to second year Masters students who have already followed the course "Experimental techniques in particle physics". It is part of the standard curriculum for the Master Physics and Astronomy at the VUB and UGent. The course focuses on actually using all concepts and techniques, including programming, that have been taught in the physics curriculum and gives an excellent preparation for a masters project. Students with a masters thesis project in particle physics or astroparticle physics are strongly encouraged to register. 

 

Anyone interested in this course should contact freya.blekman@vub.ac.be in advance for further information, including teaching schedule.  The teaching language is English. More course information can be found below and here.

Course material:

useful: root settings by downloading (and untarring in your home dir) this tar ball

Week 1: slides and macros.

Week 2: slides

Week 3: slides

week 5: slides and the particle data group review on particles passign through matter (more theoretical).

Week 6: pdf macros and the (very short) wikipedia entry on pdfs.

External Mobility for students in the Research Master Physics and Astronomy

Together with Prof. Steven Lowette I coordinate the assignment of the obligatory mobility courses, e.g., the 12 ECTS credits assigned for courses taken not at the VUB. These courses can be incorporated in international exchanges as well. Much more information on external mobility can be found here.

Measurement Techniques in Nuclear Science (Master, VUB/UGent)

Course information can be found here. This course is intended for bioengineers in a masters traject, interested in nuclear medicine applications. It explores the physics principles behind radioactivity and radiation, and the technologies necessary to detect these phenomena. Anyone interested in this course should contact freya.blekman@vub.ac.be in advance for further information, including teaching schedule.  The teaching language is English. 

Course material: will be supplied electronically after each lecture
