CV

PhD Researcher

Imperial College London

• I work on neutrino interactions, oscillations, detector analysis, and ML reconstruction techniques with Fermilab’s (American) flagship collaborations - DUNE (Deep Underground Neutrino Experiment) and NOvA (NuMI Off-axis νe Appearance) programs - under the supervision of Dr Linda Cremonesi. On NOvA I work on a variety of physics analyses.

Research Scientist Intern

Singularity Quantum · Internship

• I work alongside the research team across fluid dynamics, computational modelling, machine learning, software, quantum algorithms, and data analysis for cardiovascular computational fluid dynamics (CFD): blood-flow simulation, haemodynamic analysis, and the reconstruction problems underlying both.
• I build the mathematical and computational models, simulations, quantum algorithms, software, papers, and technical reports that carry that work: from first formulation through to something reproducible.
• I contribute to the research, development, testing, and documentation behind our cardiovascular products, principally FFR-CT and plaque analysis.
• I design, train, and evaluate physics-informed machine-learning models. Foundational models where they earn their place; physics constraints where the data runs out.
• I research tumour microcirculation, cancer-cell biology, and drug delivery, tracking the academic literature alongside the technologies, markets, and competitors moving in the same space.
• I take on quantum computing research and the quantum engineering, analysis, and business work that sits around it.

Graduate Researcher

Imperial College London

• I’m conducting cross-disciplinary research by fusing particle physics-style modelling, Machine Learning (ML), and bioengineering to decode atrial fibrillation (Afib), using spatiotemporal reconstruction and data-driven simulations to map Afib wave dynamics and reveal the underlying electrical mechanisms. To do so, my primary focus has been on utilising and implementing various Physics-Informed Neural Networks (PINN) and to architect my own framework.
• For my current PINN research project, I’m collaborating with Prof. David Colling (Imperial HEP group) and Dr. Nick Linton (Imperial Department of Bioengineering).
• Built end-to-end ML code “AtriPINN” (PyTorch): modular Wave and Eikonal and EP-PINNs backends with one shared data → train → viz pipeline.
• Delivered real-time mapping: ~78 ms end-to-end latency, ~1.6 mm RMS localisation error (sub-2 mm target), ≥ 0.99 channel cross-correlation.
• Software-engineered time-shifted kNN blending for inter-electrode signals + differentiable cross-correlation objective function for physiologic timing consistency.
• Implemented local plane-fit velocity extraction and advection-based velocity fields, and implemented coordinate-agnostic features (Cartesian, cylindrical, spherical) into my code AtriPINN.
• Scaled Neural Network training with AMP mixed precision, RAR and adaptive collocation, Adam → L-BFGS optimisation, gradient clipping, and curriculum scheduling.
• Shipped v1–v11.2 with CLI tooling, robust logging, and edge-deployment optimisations (GPU memory and throughput).
• Currently producing reproducible releases (configs, sample data, animations) to support clinical translation and benchmarking.
• Tech used: Python (PyTorch), NumPy, SciPy, Matplotlib, CUDA/GPU, CLI tooling, Git.
