DEAP-3600 (Oct 2016 - present): My role in this experiment is based on creating simulations for calibration sources and using the gained knowledge to fit energy calibration data, coming up with new methods to improve the fit and providing vital input for the experiments physics publications. During my time I took on several leadership roles as co-convener of the energy reconstruction group and co-convener of the event reconstruction group. Thus, I have experience coordinating and assigning work and providing input on peoples work. As a Run Coordinator I made decisions on what data the experiment needs to take and how frequent it should be taken, deciding on other peoples data proposals and making decisions based on their validity. My on-call work as a DAQ expert involved timely problem solving of the experiments data taking software and incorporating improvements. NEWS-G (Sep 2018 - present): My work in NEWS-G is focused on simulating detector backgrounds from different construction materials that are to be used for the experiment. I have also built a simulation of their neutron calibration source and conducted studies on lab backgrounds based on simulations for the experiment. Furthermore I am responsible for writing the source documentation for one of their calibration sources and getting it approved by the lab for use in the experiment. Show less

My research at the SNO+ experiment included building a simulation of the optical calibration system of the detector, which was designed to measure the Rayleigh Scattering of light on the detector materials. I demonstrated with using this simulation, that the Rayleigh Scattering in the detector could be measured with a 1.1% accuracy using this system. Using a cut-based analysis approach, I designed a measurement of the two main expected backgrounds for the experiment. I demonstrated, that by utilising all of the early data-taking phases, the accuracy of the measurment can be improved to statistically limited uncertainties of 27.6% and 4.1%. Additionally, I was involved in the data processing and data flow processes at the experiment, monitoring production of official Monte Carlo samples, handling issues with grid resources and maintaining the code and documentation.

Part of my studies involved a term at the SNO+ experiment during which I contributed to the detector construction. I was involved in the installation and first commissioning of the hardware for the fiber injection system my optical analysis for my Ph.D. thesis is based on. Additionally, I was involved with the preparation of the mounting plates on which the optical fibers will be installed in the detector and the database software used for logging of the installed fibers. Furthermore my tasks included Helium leak checking of the system the detector material is purified with and general preparation for the first running phase of the detector in the clean room environment surrounding the detector. During my time at SNOLAB I also had the opportunity to be involved in teaching the local undergraduate students the basics of our detector simulation software. Show less

Tutor for Specification Laboratory
-
Oct 2011 - Feb 2012
As a final year project student I was given the opportunity to take part in teaching at the TU Dresden. I was responsible for a laboratory experiment for students specifically interested in Particle Physics. The lab gave the students insights to the proton collisions as they happen at the LHC at CERN, specifically simulating the details of the ATLAS detector. The goal of this laboratory is to show students how analysis of particle physics events are done, and what computing skills are involved in processing the data. It teaches them how to track the particles in the ATLAS detector, and how to interpret results. Participating as a tutor was a great opportunity to demonstrate teaching skills and required a good knowledge of standard model particle physics and the tools used for data analysis, such as ROOT and C++.
