Projects

Persona Selection Covert Red TeamingSeptember 2026 - Present
SPAR Fall 2026 Research Fellowship Project
  • Inducing emergent misalignment via covert prompts that shift models off the assistant persona, with white-box probes to measure the shift; mentored by Ben Maltbie (Pivotal Research / MIT).
Timescape Cosmology vs. Dark EnergyJanuary 2026 - May 2026
Masters Project as a part of curriculumAvailable on GitHub
  • Investigation into performance of inhomogeneous and dynamical dark energy cosmological models.
  • Constructed data pipelines to combine overlapping catalogues of Supernovae and large-scale galaxy distribution.
  • Optimised performance of model fitting by 10x using interpolation methods and parallel-processing, enabling improved parameter fitting and modelling with larger datasets.
  • Tested Markov-Chain Monte Carlo and nested-sampling fitting methods, validating performance against known benchmark models.
  • Found timescape fits individual datasets well, but struggles to generalise to joint-probe fits, with a discrepancy in inferred void fraction between early- and late-universe fits.
  • Awarded school prizes for best research project and project poster in astrophysics, preparing paper for publishing with supervisors.
Margnap - AI Text ClassifierJuly 2026 - Ongoing
Independent project to develop ML skillsAvailable on GitHub
  • Fine-tuned DistilBERT classifier using publicly available multi-domain AI/human dataset from Hugging Face.
  • Identified in-domain 99.9% accuracy collapsing to random chance (50.05%) out-of-distribution as confounding signals in training data.
  • Evaluated acceptable FPR/FNR thresholds to balance accuracy with high impact of falsely flagging human-written content as AI, prioritising minimal FPR ≤ 1% at expense of FNR.
  • Tested performance using OOD data and adversarial perturbations (paraphrasing, word choices, character usage).
  • Differentiated discrimination failures from calibration errors across domains, recognising where threshold tuning vs. retraining could recover performance.

Leadership Experience

Elected School President of Physics & AstronomySeptember 2024
  • Concentrated on holistic school engagement program with more student-staff social initiatives such as continued ’Pints with Professors’ events. Led mid-semester intervention on disrupted module teaching, working alongside student and staff representatives to organise a targeted approach to course-correcting.
