CERN Accelerating science

New Staff members and fellows: January - March 2018

Erica Brondolin

Erica Brondolin

I am an experimental particle physicist and my research interests revolve mainly around software event reconstruction, Higgs physics and sensors characterisation. In my PhD thesis, I mainly worked in the track reconstruction of the CMS experiment for the High Luminosity LHC era. I joined the EP-LCD group in March. My involvement in the group is two-fold: on one side, I will contribute to the software development and operation of the future CLIC experiment, and on the other side, I will work on the characterisation of silicon sensors and modules for the CMS High Granularity calorimeter.

I am currently active within the ATLAS experiment, analysing the data from Run2 of the LHC and looking in particular for exotic decays of the recently discovered Higgs boson, as well as overseeing attempts to find exotic metastable (long-lived) particles that may decay within the detector. I am currently involved in assessing how sensitive our existing searches, which were targeting exotic short-lived particles, might have been to the presence of such particles given that a fraction of these theoretical long-lived particles would decay quickly. Prior to starting as a fellow I was a research associate with Brookhaven National Laboratory, and I have headed up the Analysis Software Group of ATLAS, where I have developed tools that are used across the entire collaboration

I started as a fellow in the ATLAS magnet group (EP-ADO), aiming at the technical design report of superconducting magnet system for BabyIAXO project, which is foreseen as an intermediate step towards the International AXion Observatory (IAXO). Being about one order of magnitude smaller and cost efficient, the 40 MJ BabyIAXO, with 10 m length and comprising only one 0.6 m diameter detection channel, allows investigating the optimal magnet design and demonstrating it experimentally at a rather low construction risk. BabyIAXO will have to demonstrate the maturity of the technology before undertaking the fully fletched IAXO.

I recently joined the DT-DI unit as Fellow in February 2018. Prior to this, I was a Ph.D. student at Telecom ParisTech, France, working on network measurements at scale and I was a visitor of the Center for Applied Internet Data Analysis (CAIDA), UC San Diego. At CERN, I focus on the data acquisition (DAQ) system and we aim to integrate a large distributed key-value store that would allow to decouple the lifetime of the analysis and filtering processes from the cycle of the accelerator.

I’m an experimental nuclear physicist studying the structure of exotic nuclei far from the line of stability. I started working as a fellow at the ISOLDE facility in March shortly after completing my PhD in Jyväskylä (JYFL, Finland). At ISOLDE I’m involved in experiments studying exotic nuclei with the MINIBALL spectrometer and the ISS (ISOLDE Solenoidal Spectrometer) using post-accelerated radioactive ion-beams of HIE-ISOLDE as well as at IDS (ISOLDE Decay Station) to study their decay properties.

Carlo Pandini

I'm an experimental particle physicist working with the CERN ATLAS EP-ADE-ID group as research fellow. I joined the ATLAS Collaboration in 2013 with the LPNHE group in Paris, and my focus has been the study of the Higgs boson and its properties in the bottom-quark pair decay channel. I will continue the investigation of the Higgs coupling to fermions, moving to its decay to tau lepton pairs. In parallel I will be involved in detector R&D and testing for the Pixel detector in the ITk tracker upgrade, towards the preparation of a new ATLAS inner detector for the HL-LHC.

Chris Ø. Rasmussen

Chris Ø. Rasmussen

I am a physicist and have worked on the ALPHA experiment at CERN since 2010. In January 2018, I joined EP-SME as a research fellow to continue this effort. Over the course of this fellowship, I will work on the construction and commissioning of the ALPHA-g apparatus, as well as make improvements to the 1S-2S spectroscopy of antihydrogen.

I recently joined the CLIC detector group to carry out physics potential studies for CLIC. Before coming to CERN, I worked on the first evidence for Vector Boson Scattering with ATLAS for my PhD at the TU Dresden, as well as on Higgs properties and grid computing as a postdoc at the University of Freiburg. In my fellowship, I'd like to find out the prospects for measuring the properties of the Higgs boson and for exploring the mechanism of electroweak symmetry breaking at CLIC, as well as get involved with detector development and optimization.

I am a computer scientist that joined the EP-SFT group in 2015 as a senior fellow to work on the ROOT project. Since January 2018 I am a staff member of EP, and my current areas of work include ROOT parallelization and programming model, the ROOT Python bindings and the SWAN notebook service. I am also one of the administrators of the Google Summer of Code student program (GSoC) at CERN-HEP Software Foundation and I give technical training for ROOT and the CERN School of Computing.

Pedro Miguel Vicente Leitao

Pedro Miguel Vicente Leitao

I joined the EP-ESE-ME section back in May 2013 as an electronics engineer. For the past 5 years I’ve worked for the GBT project framework, a radiation hard optical link for the LHC experiments’ readout. As a staff member I continue in the same section but I am working as an ASIC designer in the ABCStar front-end chip for the ATLAS Inner Tracker (ITk). I am looking forward to continue to make a valid contribution to high energy physics.

Simon Sels

I recently joined the EP department as a senior fellow working on the MIRACLS project at ISOLDE. The goal of this project is to develop a new laser spectroscopy technique for studying exotic nuclei. In this project, I will focus on design, simulation and construction the experimental setup. Outside of physics, I enjoy running, skiing and playing field hockey.

I joined the EP Neutrino group as research fellow in January 2018 and I am involved in the upgrade of the T2K Near Detector, in particular on the R&D of a novel plastic scintillator detector, and on the design of the DUNE Near Detector. In the past I have been a member of the T2K experiment, where I worked on the precise measurement of the neutrino oscillation parameters as well as on the search for CP violation in the leptonic sector.

Stefan Weber

I am a physicist and joined EP-DT-CO in February 2018 as a PhD fellow working on the Cosmics Leaving Outdoor Droplets (CLOUD) experiment. By having needed functionality and future requirements of the experiment in mind, I am currently reevaluating, updating and improving the integrated CLOUD data acquisition system. My main project is however concerned with studying the gas as well as ion mixing and uniformity inside the CLOUD chamber in order to understand its impact on measurements. Related to this, I will also perform computational fluid dynamics simulations of the CLOUD chamber to optimize the critical mixing parameters, such as fan speed and direction.

Anna Zaborowska

I have started my fellowship working on the Future Circular Collider hadron experiments. I participate in the design and performance studies of the calorimetry system, in particular of he electromagnetic calorimeter based on liquid argon. This includes the simulation studies, as well as the development of simulation and reconstruction software, which I have been working on previously as a doctoral student.

Joschka Pfeifer

I am Joschka Pfeifer, 27 years old, from Germany. As a new PhD Student at CLOUD, I am happy to join CERN and EP/DT. Before joining CERN I studied Meteorology at the Johann-Wolfgang von Goethe University in Frankfurt am Main (Germany). I will work as the Deputy Run Coordinator in collaboration with Hanna Manninen. During my PhD thesis, I will, among other things, quantify the effect of charge on clouds during CLOUD 14.
