Physicist with specialist knowledge in machine learning, inverse problems, analytical error propagation, iterative algorithms, and neutron spectrum measurement; as well as a strong aptitude and a unique approach to problem-solving.
PhD project: Modernising neutron spectrum unfolding for fusion applications—Sep 2023
Developed a software to systematically select foils for activation foil neutron spectrum unfolding experiments, to replace the current ad hoc approach of foil selection. Oversaw the complete software development lifecycle, beginning from stakeholders engagement to software quality control.
Derived more mathematically rigorous algorithms for unfolding, which were implemented into an unfolding code suite.
Developed a new visualization technique for presenting gamma-ray spectra based on the statistics underlying their noise distributions (Poisson distribution).
Performed an activation experiment, using GENIE to perform the nuclide identification and analysis, and then using the neutron spectrum unfolding suite developed at UKAEA to perform the unfolding.
Collaborated with other organizations to perform neutron spectrum measurements and unfold their neutron spectra to satisfactory quality.
Presented at various physics conferences, including the IoP and FuseNet.
Master’s project: Neutron spectrum unfolding suite developer (using Neural Networks)—Sep 2019
Developed a novel approach to the long-standing problem of inferring the neutron spectrum in a underdetermined system.
Collaborated with other programmers on the same repository using Git.
Developed and optimized a Neural Network using Google’s TensorFlow framework, which is then incorporated into the unfolding suite along with the appropriate documentations.
Nuclear Physics Laboratory—Dec 2019, Oct—Dec 2018
Identified unknown elements using neutron activation analysis and gamma spectroscopy using a High Purity Germanium detector.
Measured the neutron flux in neutron bath using a BF3 detector.
Analysed the results using Python’s numerical processing capability; and then visualized them graphically via Python as well.
-0.5cm-1.2cm Systematic study of the effect of neighbours on the evolution of intragrain misorientation—Dec 2018
Extracted the simulation results from Abaqus, a commercial thermomechanical modelling software, using Python; and subsequently optimized the extraction speed.
Researched and investigated various mathematical methodologies for finding the average orientation, which is a previously un-explored problem in material science.
Reported simulation result and comparison with results in literature in a paper.
Gained theoretical understanding of and practical experience with Finite Element Modelling.
Modelling of void collapse in 316L stainless steel (final year project)—Mar 2018
Developed the code for plotting (spatial and temporal) variation in grain orientation extracted from Abaqus and calibration of model parameters, as well as animation for the orientation evolution; all automated via Python.
Collaborated with other group members to steer the course of the project using the plotting results, as well as explained the relevant results in the group project report and viva.
Nuclear Talent course on Machine Learning and Data Analysis for Nuclear Physics—Jul2020
A 2 weeks course on machine learning techniques applicable to nuclear physics.
Neural network: Universal approximation theorem, backprop, autoencoders, GANs
Supervised learning techniques: Random forest, logistic regression
Unsupervised learning techniques: PCA
Reinforced learning
Exercises include: Classifying the particle tracks found in a time projection chamber TPC, classifying the number and location of events in a detector
Extracurricularly: created methods of classifying that does not rely on machine learning techniques, reducing the required computational time and resources massively.
Culham Plasma Physics Summer School—Jul2017
Learned about the relevant background knowledge in plasmas physics so to put the importance of fusion materials research in context.
Allows me to take on projects that require background understanding in plasma physics in the future.
Summer Physics internship, School of Physics and Astronomy, University of Birmingham—Aug 2018
Worked on a group project to produce a working prototype of a radiation detection drone.
Gained relevant specialist knowledge about the workings of cyclotron, GPS and radiation detector, as well as radiation protection procedures.
Fusor Group Project, University of Birmingham—Sep 2019
Recruited as part of Fusor Project team, following from an interview selection process.
Worked with 7 other more senior students to build a Farsworth nuclear fusor.
Successfully applied for a grant of £2800 on behalf of the group to cover the cost of the power supply.
Formula Student member, University of Birmingham—Jul 2016
Manufactured, shaped and resized steel and aluminium components of the test car (including Catch can holder, chassis and aluminium arches) based on the technical specification.
Researched the cost model and produced report to demonstrate manufacturing cost of a component.
Produced the cost report (in Microsoft Excel) and collected data for planning to set up factories in Europe.
Light Pollution Surveyor (social study project)—Jan 2015
Surveyed and reported the light pollution situation in Hung Shui Kiu (a region of Hong Kong). It involved using a scientific instrument (luxmeter) on site to collect data about the brightness of the vicinity, and distributing and recollecting questionnaire.
Gained valuable first-hand experience in designing and conducting a scientific investigation, building my positive attitude towards scientific investigation; and this gave me an intuitive understanding of how to operate scientific equipment with accuracy and consistency.
