CERN Accelerating science

New Staff Members and Fellows

Guillermo Brauchli

I joined the CMS Engineering and Integration Group (EP-CMX-EI) as Junior Fellow in September. The general goal of my fellowship is to provide support to the CMS Electronics Coordination Team in the upgrade of the low voltage distribution network for Phase II of the experiment. My work will be mainly focused on the development and deployment of a 400VDC power supply and distribution network in the USC5 service cavern. Additionally, I will interface with the Electrical Engineering Group (EN-EL) and collaborate with them on the overall electrical power distribution scheme at CMS-P5.

Francesco Brizioli

I am a CERN Research Fellow since July 2022 working with the NA62 experiment. I got my Master Degree in Physics in 2017 and the PhD in Physics in 2021 at the University of Perugia (Italy). After that I had Post-Doc position at the Italian National Institute for Nuclear Physics (INFN). Starting from my Master Thesis project, I have been working with the NA62 experiment, mostly focusing on data analysis. I will be continuing working in NA62, and my main research interest is the search for New Physics evidences in the Flavour Physics sector, via the study of ultra-rare processes.

Dimitrios Christidis

Dimitrios first joined the EP department in 2018, working on ATLAS distributed data management operations. Since August 2022, he has taken up a Fellow position, transitioning to a more development-focused role. The work is centred around Rucio, the software originally created for the needs of the ATLAS experiment and now used by numerous other scientific communities. Specifically, the focus is the transition from X.509 proxy certificates to OAuth/OIDC capability tokens. Dimitrios holds a diploma in Computer Engineering and Informatics from the University of Patras, Greece.

Veronika Cavaglieri

I joined EP-AGS-UO in August 2022 as a staff member. Before I have worked as flight attendant in my home country (Czech Republic), followed by 16 years as administrative assistant at EU Institutions in Brussels. In Users Office my main task is to welcome newly arrived guest scientists and provide them assistance with their first steps and establishment in their new working environment and new country. Users Office is the first spot for the newcomers and it is important to guide them and give administrative support. I am proud of being part of CERN and use mix of experience in customer service and administration.

Matteo Ferrari

I am a software engineer and I've worked for several years in a international software corporation. Three years ago I've decided to seek for new challenges and joined CERN as a Fellow. In the last 3 years I've been working for the nTOF DAQ system in the Beam Department. Now I got the possibility to push forward my experience by joining EP-ADT-DQ team as a staff member and I will work on the ATLAS TDAQ, in particular on the Event Filter Farm Orchestrator within the TDAQ Phase-II upgrades with the goal to migrate the server farm towards a reliable and robust solution based on software containers.

Joao Pedro FIGUEIREDO DE SA SOUSA DE ALMEIDA

I am a mechanical engineer junior fellow in the EP-CMX group. I started my journey at CERN as a trainee in June 2020, after completing a master’s degree in my home university of Coimbra, Portugal. Having specialized in the field of thermodynamics, I then spent my 2-year traineeship working on the mechanical integration of silicon sensor modules (for the CMS outer tracker). Now, I am delighted to extend my stay at CERN with this new opportunity where I will be working on the mechanics of the HGCAL cassette, also for CMS. Tasks will mainly focus on assembly related issues (mounting points, cable/piping routing and fixation and overall assembly procedures).

Barbara Maria Latacz

For her Research Fellowship, Barbara Maria Latacz joined the team of the BASE collaboration at the AD-ELENA facility. Within her studies, she will focus on the development and commissioning of a new, highly optimized 4-Penning-trap system with the goal to measure the antiproton magnetic moment with a much higher sampling rate and 10-fold improved precision. Together with an improved measurement of the proton magnetic moment, also planned in BASE, this will result in a new highly precise test of the CPT invariance. She will also contribute to the development of the transportable antiproton trap BASE-STEP and the axion haloscope BASE-CDM.

Peilian Li

I am very excited to join the EP-LBD group as a research fellow in September. I joined the LHCb experiment as a postdoctoral research assistant at the Heidelberg University since 2019, where I was involved in the software trigger development with tracking reconstruction for Run 3 and CP violation measurement in B decays.

I will continue my contribution in tracking reconstruction for the Run 3 data-taking and finalize the measurement of charm production cross section with early Run 3 data. I would like to extend my expertise by contributing to the hardware development and lepton universality measurement.

Aleksandra Onufrena

My name is Aleksandra Onufrena and I joined EP-DT as a thermal / mechanical engineer. I am working within ATLAS ITk upgrade project. I perform a mechanical and thermal design and analysis (ANSYS, Matlab) of beam conditions monitor that is essential for safe operation of the ATLAS detector. Moreover, I am responsible commissioning and operation of a new CO2 cooling testing facility used for sizing and qualification of the capillaries for integration into the cooling chains of ITk Pixel and Strips detectors. I am open to hearing from you if I can help with any questions!

Fernando Perea Albela


Hi! I am Fernando Perea Albela. I am the new Junior Fellowship in the EP department. I will be working for Constructions & Operations section, in the Detector Technologies group. This is my second experience in the EP department. Previously, I did my Technical Studentship working on the TB2S cooling. Now I will carry on with the work on the CMS Phase-2 Upgrade. I will carry out design, production and quality works of the TBPS, in the Outer Tracker. This period will be challenging, and I am very excited about doing my part to achieve all the objectives of the project.

Huilin Qu

I recently joined the EP-CMG group as a research physicist, after completing a senior research fellowship at CERN. My research interests are centered around searches for new physics and measurements of the Higgs boson properties, particularly using novel approaches and advanced techniques such as deep learning. I am currently focused on the study of the Higgs coupling to the charm quark and the Higgs self-coupling with the CMS experiment. In addition, I am also actively involved in the upgrade of the CMS High Granularity Calorimeter for HL-LHC, contributing to the development of reconstruction algorithms and the system tests of the readout electronics.

Nikos Tsipinakis

I am a Computing Fellow with the title of Distributed Computing Infrastructure Engineer in the CMS Computing group (EP-CMG-CO). My duties involve administrating, maintaining and improving the CMS Submission Infrastructure, the service that allows CMS scientists to submit computing jobs to be run by datacenters worldwide. I have a Bsc degree in Informatics & Telematics and I'm active in the open source software scene. I am also actively involved with the ContainerSSH open source project, which I helped develop as part of my previous position as a Technical Student in the IT department.

Lucian Scharenberg

During my Master’s and my time as CERN Doctoral Student, I have worked on readout electronics (Timepix/GridPix and VMM3a/SRS) for Micro-Pattern Gaseous Detectors (MPGDs). With the fellowship in the Gas Detector Development (GDD) team, I will continue to work on MPGDs, but with the goal of exploring new detector technologies, like large area µRWELL detectors, low material budget detectors or hybrid detectors, combining gaseous detectors and solid state technologies.

Szymon Wlodarczyk

I am a mechanical engineer who has also dabbled in aerospace engineering. I came to CERN from Poland as a Technical Student in September 2021 working in TE-VSC-DLM, but now I have continued my time here as a Junior Fellow in EP-DT-EO. Broadly speaking I will be working on the Hi-Lumi upgrade of the LHC. More specifically the new inner silicon tracker systems of ATLAS and CMS. I will be working alongside the people from the engineering office and many others, helping with designing, calculating/analyzing, and manufacturing support structures and thermal and electrical systems for the new silicon trackers. I am excited to be here and eager to help the team finish the project successfully.
