I am a researcher at the Van Swinderen Institute for Particle Physics and Gravity, working in the High Energy Frontier. I participate in the Large Hadron Collider beauty (LHCb) experiment, studying the spontaneous disintegration of rare subatomic particles that contain the heavy beauty quark. These exotic particles are a powerful tool to test the Standard Model of elementary particle physics, describing the fundamental building blocks of our Universe and their interactions. Recent experimental results from the LHCb experiment have found puzzling discrepancies with the Standard Model predictions when comparing select decay paths containing electrons, muons or tau leptons with one another. I would like to understand the origin of these discrepancies, and am therefore setting up a new measurement of a similar but slightly different decay processes: the disintegration of a subatomic particle made from the combination of a beauty and a charm quark into a tau lepton and its neutrino.In addition to analysing the data collected by the LHCb experiment, I am also involved in the construction, commissioning and operation of LHCb's innermost silicon pixel detector, the Vertex Locator. This detector is crucial for identifying particles containing beauty quarks from among the many other particles created in the proton-proton collisions produced by the Large Hadron Collider.Signs for new particle physics phenomena are extremely rare and hence require millions of collisions per second to be analysed in real-time. If we want to continue this search in the future, we wil need to collect more and more data with the LHCb experiment. This requires the development of new technology relying on picosecond timing information to separate the collisions from one other in both space and time. I am involved in the R&D for the next generation silicon pixel detectors, focussing on how we can time-align all individual pixels at the picosecond level.

_{(1) Tests of Quantum Gravity via Quantum Entanglement in a laboratory. I am one of the key proponents of this idea, along with my key collaborators. "Spin entanglement witness for quantum gravity ."  We are aiming to design the tiniest (micron-size nano-crystals) particle accelerator to create the Schrödinger Cat state in a laboratory to test the quantum nature of spacetime. In particular, this will lead to the very first demonstration that the gravitational interaction with the matter is quantum in nature. In the context of a perturbative quantum gravity this would surmount to understand the properties of spin-2 nature of the graviton " Mechanism for the quantum natured gravitons to entangle masses ", and " Locality and entanglement in table-top testing of the quantum nature of linearized gravity ". (2) To test Quantum Gravity induced Entanglement of Masses (known as QGEM protocol), we will need to create a macroscopic quantum superposition with heavy masses, large superposition, and a long coherence timescale. Our group is closely working with experimental groups to realize such a protocol in a laboratory: " Realization of a complete Stern-Gerlach interferometer: Towards a test of quantum gravity ", and " Constructing nano-object quantum superpositions with a Stern-Gerlach interferometer ".
(3) Our group is designing a matter-wave interferometer that can act as an accelerometer " Mesoscopic Interference for Metric and Curvature (MIMAC) $\&$ Gravitational Wave Detection ". One of the key areas of improvement is required in the noise reduction, especially gravity gradient and relative acceleration noise " Relative acceleration noise mitigation for nanocrystal matter-wave interferometry: Applications to entangling masses via quantum gravity " . Furthermore, we will also require ameliorating our background due to Electromagnetic interaction, such as Casimir potential " Quantum Gravity Witness via Entanglement of Masses: Casimir Screening " .
(4) Testing quantum gravity with LIGO/VIRGO data, probing quantum features of gravity from quasi-normal modes & shadow of black holes . I am interested in probing the quantum nature of a compact object which can mimic the properties of a classical black hole.
(5) Resolution of Cosmological & Black hole singularities . Imbedding inflation in the quantum theory of gravity . I initiated ideas on resolving cosmological singularity with infinite derivative theories of gravity which is free from perturbative ghosts. Such theories can potentially resolve the black hole singularity and the information-loss paradox.
(6) Baryogenesis, dark matter, non-topological solitons, thermal/non-thermal phase transitions and gravitational waves . I am interested in how non-trivial phase transitions in the Early Universe can lead to the gravitational wave background in LIGO/VIRGO and LISA experiments.}

I have experience in the detection of high-energy messengers, including neutrinos, CRs and gamma-rays. I have five years of experience in neutrino astronomy, for her PhD and one post-doctoral fellowship on the ANTARES and KM3NeT underwater neutrino telescopes. During my PhD I set the first upper limit on the flux of neutrinos from the supergalactic plane, and later worked on the search for neutrinos from the Fermi-Bubbles. My technical contributions in neutrino astronomy include the development of an online reconstruction algorithm for a real-time optical follow-up of neutrino events and the characterisation of optical properties of deep-sea sites for the installation of future neutrino telescopes in the Mediterranean. I have ten years of experience in the detection of Galactic Cosmic rays, as a member of the Alpha Magnetic Spectrometer (AMS-02). My main contributions to the AMS-02 collaboration are related to the calibration of the electromagnetic calorimeter, and to the analysis of the electron and positron fluxes. I am currently working on the isotopic composition of Galactic CRs. I am a member of the CTA Collaboration since 2015, and I have been working on DM searches from the dSph galaxies. I also have experience in the phenomenology of CR sources and propagation, being the author of several papers on this topic. I am a Rosalind Franklin fellow and tenure-track assistant professor at RUG since 2018.
