Front cover of "Amsterdam Diaries, Life Writing and Identity: Urban Lives"
First page of my chapter, titled "fetching dogs from depositions"
A little while ago my very first publication came out - a chapter in a book on life in Amsterdam through the ages. It's based on a bit of my master's research on dogs in the Dutch capital. It explores methods of uncovering animal history and shows a glimpse of dogs' lives. Open access is pending!

After two weeks of travel I'm finally reunited with my rats :D
A print depicting a man reading in a train with a ghostly devil next to him. The text reads "Danger forever remains your invisible travelling partner. Insure yourself against travel accidents with Fatum" (my translation)
A print depicting a city in disarray: a bus drives into a pit, a car hits a lamp post, a piano is about to fall onto a pram, a man is falling out of a window, and many more disasters. Above it all hangs a bloody sword marked "accidents". The print is captioned "this sword hangs over all your heads! Insure yourself in a timely fashion with the M-Z" (my translations)

The ‘Loyalty in the Medieval World’ network welcomes proposals which explore the intersections between the concept of ‘loyalty’ and the IMC 2026 theme of ‘temporalities’. Was there a shift in how the concept of loyalty was used and perceived by people across the Middle Ages? To what extent, if at all, were bonds of loyalty an archaic predecessor to the coercive potential of a centralising medieval ‘state’? How did the language (e.g. treue, fides, leal), theories, and practices of loyalty change or stay the same in the medieval period? What can the study of loyalty do for the historian of medieval political society? Submissions could reflect on: • Emotional frameworks of loyalty • Political frameworks of loyalty • Ethical and legal frameworks of loyalty • The theory and practice of loyal behaviour • Loyalty and identity • Loyalty and power • Horizontal loyalties and solidarities • The material culture of loyalty • Contested and/or multiple loyalties • Disloyalty , such as women, children, exiles, and migrants. Please send a paper title, affiliation, and abstract of up to 150 words to Eleanor Bailey ejbailey98@outlook.com, Katy Bennett katy.bennett@york.ac.uk, AND Jenny McHugh j.mchugh@lancaster.ac.uk. Deadline 15th September.
Call for Papers @imc-leeds.bsky.social 2026 ‼️ The 'Loyalty in the Medieval World' network welcomes papers which explore the intersections between the concept of ‘loyalty’ and the conference theme of ‘temporalities’, c.500-1500! Get in touch by 15 September

It's #worldratday! To celebrate, I wrote a pretty fun post for the @archaeorattus.bsky.social project blog about #rats nibbling on #archive material. Check it out! sites.google.com/york.ac.uk/r...
A screenshot of a news broadcast featuring a photo a group of protesters, with me prominently in the centre holding a sign that says "Rich Tice? I'd rather have head lice"
My beautiful sign and I have become the face of #antifa in English rightwing media this weekend after a peaceful protest against #ReformUK in #York! I couldn't be more proud :)
