About Me
I am currently a DPhil student in the Particle Theory group of the Department of Physics at Oxford under the supervision of Professor Andre Lukas (his personal webpage is here). I was previously a student at the University of Cambridge, having completed Parts I and II of Natural Sciences Tripos (NST) and Part III of Mathematical Tripos. Here is my CV.
Research
Current Research
Broadly speaking, my main research interests lie in the intersection of mathematics and physics. The particular area I am mostly involved in is something known as "String Phenomenology". This involves using algebraic and differential geometric techniques to analyse phenomenological models from string theory. In simple words, we try to see whether we can get the Standard Model from string theory.
String theory remains the only consistent Quantum Gravity (QG) model that mathematicians and physicists can study and manipulate. Our group is interested in obtaining viable models directly from superstring theory, ultilising a technique called 'string compactification'. Namely, we reduce the ten-dimensions in superstring theory down to four-dimensions where we reside. The six-dimensions, known as the 'compactifified' dimensions, have specific topological and geometrical properties which determine the low-energy (real-world) data. Currently, I am mainly interested in the details of non-pertubative effects that arise in heterotic E8xE8 string compactifications on line bundles of CICYs, as well as ultilising Data Science techniques to search through viable models that can appear in heterotic compactifications.
Reading Group
In Hilary Term 2023 I had organised a reading group on AdS/CFT with the other DPhil students. The reading group page can be found here. Note that the reading group has ended since Trinity 2023.
Teaching
I am currently teaching Supersymmetry and Supergravity, lectured by Dr. Michèle Levi. You should be able to the sign-up to the classes on Moodle. There will be additional notes given after each class. The details are on the Moodle page.
In Hilary 2023 I am the teaching assistant (TA) for Strings I. In Michaelmas Term of 2022-24 I was a tutor for Groups and Representations.
Old Research
I previously completed a project with Dr Michal Kwasigroch, a temporary college lecturer in Trinity on Mean Field Theory analysis of RKKY and Kodo interactions in a Kondo lattice. A temporary detailed report can be found here.
In 2020 I did a summer poject on lubricated icesheet perturbation analysis with Dr Katarzyna Kowal in DAMTP. A short report can be found here.
Outreach
QCPhO Training materials
In the summer of 2020 I taught a short course in my secondary school on Newtonian physics and some mathematical techniques. The course book can be found in the link below:
Problem Book on Classical Mechanics
I was also the tutor and then the advisor for the student-run QCPhO Training Course from 2015-2017. Some notes that I have made throughtout the years can be found below.
Notes on Simple Harmonic Motion
DSE Physics
I have been helping (unofficially) students in my secondary school in their DSE preparation during the COVID-19 pandemic. Here are some useful resources.
Conceptual Questions Answers will be added soon!
Other Fun Stuff
I am an enthusiastic triathlete (and perhaps one of the only asian faces in the club...)! I am involed in the Oxford University Triathlon Club and am the Men's Captain in year 2024-25. Our club webpage can be found here.
I also compose music (here is a link to my Youtube Channel).
I did an Undertale Medley arrangement for an ensemble when I was in Cambridge. I had arranged and orchestrated the pieces we are going to perform. Here is an example.
