Description End-to-end deep neural network vertex reconstruction and association algorithm development for the Phase-II Level-1 Trigger Upgrade in the CMS detector 
Organisation Imperial College London
Department Department of Physics
Country United Kingdom 
Sector Academic/University 
PI Contribution Collaborative research with Imperial College London high energy physics researchers towards the Phase-II Level-1 Trigger Upgrade in the CMS detector. I developed and trained a number of machine learning algorithms and compared their relative performance for track-to-vertex association that would be integrated into the end-to-end neural network framework.
Collaborator Contribution Collaborative research with Imperial College London high energy physics researchers towards the Phase-II Level-1 Trigger Upgrade in the CMS detector. My colleagues developed a deep neural network-based vertex reconstruction algorithm for high-luminosity pile-up rejection purposes in the Phase-II Level-1 Trigger Upgrade of the CMS detector.
Impact I received EPR credits within the CMS collaboration to become an author. No paper or technical report has been published, yet, it is still ongoing work. The work is mentioned in Section 3.4 of the newly published "ThMS Level-1 Trigger Technical Design report (Report number: CERN-LHCC-2020-004, CMS-TDR-021).

Description Searching for long-lived heavy neutral leptons in hadronic decays with the CMS detector using a novel deep neural network-based displaced jet tagger 
Organisation European Organization for Nuclear Research (CERN)
Department CERN LHC CMS
Country Switzerland 
Sector Academic/University 
PI Contribution Collaboratively working on the aforementioned analysis using data collected by the CMS detector between 2016-2018. Personally, I am working on training an event-level classifier to distinguish signal events from background.
Collaborator Contribution Collaboratively working on the aforementioned analysis using data collected by the CMS detector between 2016-2018. Some of my colleagues trained a novel deep neural network-based long-lived jet tagger for signal processes we are searching for, as well as evaluating the statistical significance and systematics of the result of this analysis.
Impact We are entering the write-up and review period of the analysis within the CMS collaboration. We expect the analysis to be accepted and published in half a year.

Results and Impact I was invited as a female alumna for a networking online event of the Poynting Physics Society at the University of Birmingham where I conducted my undergraduate degree. I engaged with undergraduate students and presented my journey towards successfully securing a fully-funded PhD in high energy physics at Imperial College London. I talked about my current research, PhD student life and I answered to their questions.
