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.

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.
Darjeeling, bergamot & lavender bonbons Dark Callebaut chocolate (54%) bonbons, filled with a milk chocolate ganache infused with Earl Grey Darjeeling tea and lavender
