I build deep learning and representation learning systems for clinical data.

PhD student at Imperial College London working across proteomics, electronic health records, and wearable data to build predictive, interpretable models for Parkinson's disease and related clinical monitoring problems.

Profile

I work on modelling problems where the artifact matters as much as the idea: calibrated prediction, multimodal fusion, interpretable outputs, and tools that can be inspected through papers, demos, and case studies rather than abstract claims.

Projects

Selected projects and case studies.

Research spanning predictive modelling, deep learning, and clinical translation.

Flagship

Plasma Proteomics and Machine Learning for Parkinson's Disease Prediction

Develop machine learning approaches for Parkinson's disease prediction from plasma proteomics and evaluate how the signal generalizes across datasets.

  • Large-scale plasma proteomics data, with external validation in an independent cohort.
  • Supervised machine learning, explainability analysis, calibration checks, and model error analysis.
  • Interpretable risk modelling with attention to robustness and generalizability.
Deep Learning

Multimodal EHR + Proteomics Fusion

Learn shared patient representations from structured EHR and proteomics to improve subgroup discovery and prediction.

  • Longitudinal EHR plus targeted proteomics.
  • Deep learning and representation learning for multimodal fusion.
  • Ongoing work on stratification and interpretable latent structure.
Tool

Agitation Monitoring Demo

Detect and inspect agitation episodes in dementia using remote monitoring signals and an interactive demo.

  • In-home monitoring and longitudinal behavioural sensing.
  • Interpretable ML for episode detection.
  • Publication in The Lancet eClinicalMedicine and a live Hugging Face demo.
Remote Monitoring

Agitation Profiles in Dementia

Characterize heterogeneous agitation patterns from longitudinal in-home monitoring data.

  • Repeated in-home monitoring measurements over time.
  • Longitudinal profiling and interpretable analysis.
  • Distinct agitation profiles reported in Alzheimer's & Dementia.
Flagship Project
Parkinson's Disease

Plasma Proteomics and Machine Learning for Parkinson's Disease Prediction

This project explores whether plasma proteomics can support Parkinson's disease prediction and whether machine learning models can recover clinically meaningful signal from large-scale biomedical data.

  • Research question: can plasma proteomics contribute useful predictive signal for Parkinson's disease, and what can model behaviour reveal about heterogeneity in the data?
  • Large-scale plasma proteomics data, with additional validation in an independent cohort.
  • Supervised machine learning, explainability analysis, calibration checks, and error analysis.
  • The project focuses on interpretability, generalizability, and understanding where models succeed or struggle.
  • Overall, the work is aimed at informing more reliable biomarker-driven prediction tools.
What I Build

Core strengths across modelling, data fusion, and translation.

Work spanning multimodal integration, model development, evaluation across datasets and deployment.

Multimodal Modelling

Prediction and clinical stratification across heterogeneous health data

Combining targeted proteomics, electronic health records, and smartwatch-derived digital biomarkers to improve early prediction and subgroup definition.

Deep Learning

Representation learning for structured and longitudinal clinical signals

Designing deep learning pipelines that learn useful latent structure from multimodal patient data while preserving interpretability and portability.

Deployment Mindset

Cross-cohort evaluation and interpretable outputs

Evaluation spans calibration, explainability, and external validation across large-scale biomedical datasets.

Training

Technical formation across neuroscience, biology, and machine learning.
