Evolution of a smile: 400 million year old spiny fish overturns shark theory of tooth origins

We wrote an article in The Conversation explaining the significance of our paper on tooth development in the "spiny sharks".

The paper was also covered in Nature Today, among other outlets

I was also interviewed on SAfm sunrise, the South African Broadcasting Corporation's morning radio show.

Placoderm jaw evolution covered in Nature Today [in dutch]

A write-up of our paper on Bayesian dynamic homology methods and placoderm evolution.


Outreach talk live on facebook cooperating with Readerland on 27th June . The talk examined the environment and climate during the age of dinosaurs, a fascinating event called the “Palaeocene-Eocene thermal maximum” and the aftermath of the two greatest extinction events in history: the Permian-Triassic, also known as the “great dying”, and the end-Cretaceous, which famously wiped out the dinosaurs. Talk was live-streamed, and the video can be viewed here

Gall wasp life cycle

I recently dug up this video I made as a teenager, which shows the complete life cycle of the gall wasp Andricus kollari, including footage of the asexual generation emerging from the gall. This fascinating species shows alternation of asexual and sexual generations, which look completely different, and live in different species of oak. Click here to see the raw footage of the asexual generation emerging (if you dare)!

Our article about electroreception in the conversation

We wrote an article for The Conversation about our paper on the origins of electroreception

A primer on Bayesian inference

Together with Mike Lee, I wrote a primer to Bayesian inference at The Conversation. This article has received more than 70,000 views, and is useful for both undergraduates and the general public.
