CERN Accelerating science

New Staff members and fellows: October - December 2019

Nordin Aranzabal

I am a CERN Fellow working on the integration tests and commissioning of the Phase-1 Upgrade of the ATLAS Liquid-Argon (LAr) calorimeters trigger readout. New electronics for this trigger system will be installed on ATLAS during the 2019-2021 long shutdown (LS2). The design of all the electronics boards is completed and tests are currently on going to validate production boards before their imminent installation. I will contribute on the effort to code the required functions expected for the trigger readout chain into the various powerful top-of-the-line field programmable gate arrays (FPGA) and the required tasks for the system installation and commissioning.

During my PhD I was involved in the ATLAS ITk Pixel project - in particular in test beam studies of pixel sensors for the ITk upgrade. In this project I was developing software for the data acquisition (DAQ) as well as particle track reconstruction and analysis of test beam data. After a short side trip into the world of calorimetry, where I was studying technologies for highly granular calorimeters, I am back to working with pixels. I joined CERN to work in the ATLAS Pixel Operations team, devoting myself not only to day-to-day operations business, but also contributing to DAQ development. I also hope to participate in the ongoing ITk upgrade, linking the current detector to the future one.

I am a Microelectronic Engineer, having just recently completed my PhD at The University of Edinburgh. I am a new senior fellow in the EP-ESE back-end section, under the principal supervision of Dr. Jan Troska. The fellowship project consists of designing a new driver ASIC (application specific integrated circuitry) for a new generation silicon photonic communication modulators for future LHC experiments. I will be involved in device-level simulations and laboratory testing of the silicon photonics, in order to generate electrical models of the device, which will be used to validate the ASIC design

After finishing my PhD in physics at the University of Heidelberg, I joined the CERN LHCb group as a research fellow in November. My scientific interests have revolved around the rich phenomenology of multi-body beauty and charm meson decays. These decays provide an excellent laboratory for the spectroscopy of excited hadronic states and studies of CP violation. Besides working on physics data analysis, I am keen to participate in upgrade activities to contribute to the long term success of the experiment.

I am a mechanical designer for the ATLAS Experiment. As a staff in the Technical Coordination (EP-ADO-PO), I have to design systems for detector components, such as supporting structures, tooling, & platforms. The aim is to prepare the upgrade of ATLAS for LS3. I am also involved in the integration and the maintenance of the 3D CAD environment, with reverse engineering activities.

After doing my PhD at LAPP (Annecy) on Higgs boson measurements in the diphoton channel, I am joining the CERN ATLAS team as research fellow. I will continue my research work on measurements of the Higgs boson properties, focussing on the ZH cross section within the H to bb group. In parallel I will participate in the testing of the ITk pixel detector which will be installed in ATLAS for the HL-LHC.

Michael Pitt

I am an experimental particle physicist, and I started as a research fellow at the EP Department in September 2019. I did my Ph.D. at the Weizmann Institute of Science, where I worked on data analysis and R&D of particle detectors, and now I joined the CERN-CMS group. As a research fellow, I will focus on studying the properties of the top quark, and I will explore new research opportunities in the physics of diffractive processes, using combined data collected by the CMS detector and the CMS-TOTEM precision proton spectrometer. I will also work on the Phase II upgrade program of the CMS Level-1 trigger system.

Thorben Quast

My doctoral thesis was focused on the experimental validation of the silicon-based CMS HGCAL design through beam tests and on fast simulation of its data using state-of-the-art generative modelling techniques. Now, as an applied fellow I will be extending this work hereby contributing to the realisation of the ambitious HGCAL project. In particular, I will be working on the timing capability aspects to establish a realistic calibration strategy, on the qualification of the final sensors and readout electronics, and on the development of the associated experimental infrastructure as well as the respective data reconstruction algorithms.

I am a new research fellow at CERN joining the ATLAS team. I completed my PhD in CEA-Saclay (France) and spent the last three years at DESY-Hamburg (Germany), as a research fellow. During these years, I worked on QCD precision measurements, dark matter searches, and photon and b-jet identification. At CERN, I plan to get strongly involved in the Level-1 trigger operations and to search for deviations from the standard model in ATLAS data. My interests include probing the nature of the Higgs Yukawa-like couplings, their possible connection with dark matter, and alternative mass generation mechanisms, e.g. involving Majorana terms.

I have joined the EP-LBC group as a fellow working on LHCb’s software build, release, and test infrastructure. I have obtained my PhD in Physics at the Warsaw University of Technology, working on femtoscopic correlations in heavy-ion collisions, and event display in ALICE. Afterwards, I joined the LHCb Core Software Group as a postdoctoral researcher at the University of Chinese Academy of Sciences. My work was focused on the framework for measurements of the software performance.
