About me...

I have worked at the Natural History Museum in London for over ten years in a variety of roles; including running the live tropical butterfly house, as a behind the scenes tour guide, visitor assistant and in the entomology and earthworm research labs and collections. I am also a trustee and tutor for the Earthworm Society of Britain (yes, there is such a thing) and am very passionate about all aspects of natural history but particularly engaging people in the world of the humble but super important earthworm.

About my Talks...

My talks typically last for 40 – 50 minutes with extra time after for any questions but I am happy to tailor the timings and content of my talks to your group and needs.

My talks are typically delivered with a Powerpoint presentation, I have my own laptop  but would need the use of a  projector  OR I can do stand alone talks if you don’t have a projector available.

All of my talks are currently available virtually.


I charge £75 (excluding travel) for my talks, which are typically 40 – 50 minutes long plus time for questions. If you are looking for a longer or tailor-made talk for your group then the fee may vary depending on your requirements, but please contact me and we can discuss this.

Travel expenses claimed would be from public transport.

My Contact Details:


Learn to Love Earthworms

Learn to Love Earthworms – the humble earthworm is arguably one of the most important and influential organisms on Earth today. Most people know what an earthworm is and you probably played with them as a child, we know that they are important for our soils but beyond this most of us know very little about them. In this fun and engaging talk I hope to change that and will discuss the basics of earthworm diversity, biology and look at why they are so important. I will of course also let you know what happens if you chop one in half!

Darwin’s Earthworms

Darwin’s Earthworms – Charles Darwin might be best known for his work on evolution and his time on the Voyage of the Beagle but to me he is the father of earthworm science. After 44 years of studying earthworms, he published a best-selling book dedicated to the group, which is still one of the go to resources for researchers today. In this talk I look back at the history of earthworm science and research and describe some of the experiments Darwin did with earthworms.

Gardening for Earthworms

Gardening for Earthworms – earthworms are extremely important for our gardens and do lots of hard work for us. From composting our kitchen waste to ploughing our flower beds, decompacting our lawns to feeding the birds, I will discuss the jobs in the garden that worms do for us and look at some of the ways that we can help and encourage them.

Beautiful Butterflies

Beautiful Butterflies – over the last 30 or so years many tropical butterfly houses have opened up around the country and they are very popular with visitors of all ages. I have worked on many of these projects most notably the summer exhibitions that were held on the front lawn of the Natural History Museum in London. In this talk I will introduce you to some of the most charismatic and popular species seen in these exhibitions and share some of the behind-the-scenes secrets and “I can’t believe that just happened moments” from the butterfly house world.

Specimens of the Natural History Museum

Specimens of the Natural History Museum – the Natural History Museum in London is home to one of the most important natural history collections in the world. With more than 83 million specimens, the collections are extremely diverse and invaluable to science. In this talk I will look at the stories behind some of the best-known specimens; from Archie the Giant Squid to Sophie the Stegosaurs, and the slice of Giant Sequoia tree to Hope the Blue Whale. I will discuss how these specimens came to be in the museum, what they were like in life and what scientists have learnt from them. (If your group has an interest in a particular specimen or group of animals, I am very happy to include the relevant specimens in this talk where appropriate).
