Can a scan catch the stage before dementia?
3D convolutional neural network for early diagnosis of Alzheimer's disease from 18F-FDG PET brain scans, separating cognitively normal, mild cognitive impairment and Alzheimer's at 92.31% accuracy, and up to 96.91% pairwise.

A surgeon is about to open this knee. What is already inside it?
Web platform where doctors upload an X-ray and a CNN identifies the orthopaedic implant by joint, so the model is known before revision surgery. Seven models on AWS, in use at Luton and Dunstable University Hospital and by orthopaedic surgeons worldwide.

Can a model diagnose through the noise?
A two-level U-Net that strips Gaussian noise from brain MRI scans, lifting PSNR from 11.90 to 30.96 and raising tumour classification accuracy by 23% on average across six CNNs. Published at IEEE ICAST 2022.

Can a network hear a motor disorder in 25 milliseconds of speech?
A hybrid CNN-LSTM that classifies dysarthric speech from 128 MFCC features, reaching 99.59% accuracy on the TORGO recordings of speakers with cerebral palsy or ALS. Published at IEEE ICAST 2022.

Where exactly is the eye leaking?
A Recurrent Residual U-Net that segments exudates, an early sign of diabetic retinopathy, with 93.20% sensitivity and 99.80% specificity at the lesion level on E-Ophtha.

Which of these leaves is sick, and with what?
An ensemble of Xception, InceptionResNet and MobileNet that reads scab, rust, frogeye leaf spot, powdery mildew and complex infections off apple leaf photos from the Plant Pathology 2021 dataset, including leaves carrying more than one disease.

How do you watch one price on many sites, in three currencies, without spamming the buyer?
Telegram bot that monitors digital asset prices across multiple platforms and sends real-time alerts with direct purchase links.

One app, many independent shops. Who gets to approve a sale?
Multi-tenant SaaS for ordering groceries online from local stores, each store running its own catalogue and orders, with an admin panel that authorises sales.

Which shadow matters?
EEF-Net, an enhanced EfficientNet for classifying breast tumours in mammograms, where dense tissue and lesions share the same grey.
