I am currently a PhD student at the University of Manchester in the Accelerator physics group working with Prof. Roger Jones. My project involves simulation and experimental studies with electrons in energy ranges 50-250 MeV for radiotherapy purposes. Before my PhD studies I finished an MPhys at the University of Manchester.

We investigated how inserts of various densities (0.001-2.2 g/cm3) affect the dose distribution
properties of VHEE beams at ~150 MeV. A range variation comparison was also made with clinical proton beams
using TOPAS/GEANT4 Monte Carlo simulations. In addition, we assess the viability of scattering foils for
optimizing the size of VHEE beams for radiotherapy purposes. The experiments were conducted at CERN's CLEAR user facility.

The new "CERN Linear Electron Accelerator for Research" (CLEAR) facility at CERN started its operation in fall 2017.
CLEAR results from the conversion of the CALIFES beam line of the former CLIC Test Facility (CTF3) into a new testbed for
general accelerator R & D and component studies for existing and possible future accelerator applications.
CLEAR can provide a stable and reliable electron beam from 60 to 220 MeV in single or multi bunch configuration at 1.5 GHz.
The experimental program includes studies for high gradient acceleration methods, e.g. for CLIC X-band and plasma technology,
prototyping and validation of accelerator components, e.g. for the HL-LHC upgrade, and irradiation test capabilities for
characterization of electronic components and for medical applications. An overview of the facility capabilities and a
summary of the latest results will be presented.

A new resist material for electron beam lithography has been created that is
based on a supramolecular assembly.
Initial studies revealed that with this supramolecular approach,
high-resolution structures can be written that show unprecedented selectivity
when exposed to etching conditions involving plasmas.

We investigated the effects of heterogeneous regions on dose deposition of very high-energy electrons (VHEE) using
both Geant4 simulations and experiments performed at the CALIFES facility at CERN.
Small air and acetal plastic (bone equivalent) cavities were embedded in a water phantom
and irradiated with a 197 MeV electron beam. Experimentally determined transverse dose profiles were acquired
using radiation sensitive EBT3 Gafchromic films embedded in the water phantom at various depths. EBT3 Gafchromic
films were found to be a suitable dosimeter for relative dose dosimetry of VHEE beams. Simulated and measured results
were found to be consistent with each other and the largest
discrepancy was found to be no more than 5%. Dose profiles of VHEE beams were found to be relatively insensitive to
embedded high and low density geometries.
