Interests

Whether it's training a neural network or tempering chocolate, I keep returning to the same question: how does this actually work? These pages collect the writing that came out of that curiosity.

Research & AI

My PhD focused on using deep learning for prostate cancer diagnostics. These posts cover the research, the datasets, and the competitions that came out of it.

Jan 2022 AI for diagnosis of prostate cancer: the PANDA challenge Artificial intelligence (AI) for prostate cancer analysis is ready for clinical implementation, shows a global programming competition, the PANDA challenge.

Feb 2020 The potential of AI in medicine: AI-assistance improves prostate cancer grading In a completely new study we investigated the possible benefits of an AI system for pathologists. Instead of focussing on pathologist-versus-AI, we instead look at potential pathologist-AI synergy.

Jul 2019 The public PESO dataset: prostate H&E whole-side images for epithelium segmentation Public dataset of prostatectomy whole-slide images for epithelium segmentation, licensed under a BY-NC-SA Creative Commons license.

Jul 2019 Pathologist-level Gleason grading using artificial intelligence (AI) & deep learning We developed a fully automated deep learning system to grade prostate biopsies using 5759 biopsies from 1243 patients, and showed that this system achieved pathologist-level performance.

Recipes

Mostly chocolate, mostly dessert. I test recipes until they work reliably, then write them up so others can reproduce the results.

Blueberry cheesecake ice cream (Sous vide) Rich ice cream with a fresh tangy blueberry swirl. Using a dehydrator we can add an extra dimension to the blueberry swirl.

Sous vide ice cream base: a foolproof method The ice cream base is the most important part of ice making, but can be difficult to get right. Heating the base sous vide helps to reduce errors.

Chocolate entremet (mousse cake) with Amarena cherries This dark chocolate entremet is a great way to end a dinner. Sour Amarena cherries nicely complement the richness of the chocolate.

Ruby chocolate bonbons Tutorial on making ruby chocolate bonbons with various fillings.
