Ada Lovelace Day Live!

Join us to celebrate the 15th year of Ada Lovelace Day Live.

Ada Lovelace Day logo

Ada Lovelace Day Live is back! The annual ‘science cabaret’ returns with a fantastic line-up of women in science, technology, engineering and maths (STEM), who will share their experiences, insights and expertise, inspiring and empowering the next generation of women in STEM.

Hosted by comedian Helen Arney, the show will feature Jennifer Rohn, head of the Centre for Urological Biology, University College London, Azza Eltraify, senior software engineer at Ultracell Networks Ltd, Sophie Carr, mathematician, Bays Consulting Limited, Aarathi Prasad, writer, broadcaster, geneticist and Anjana Khatwa, Earth scientist and presenter, Antonia Pontiki, biomedical engineer at King's College London, and Rosie Curran Crawley, presenter at L'Oreal Young Scientist Centre. For full details of all our speakers and their talks, take a look at the Ada Lovelace Day website.

Now in its 15th year, Ada Lovelace Day Live is a global celebration, highlighting and honouring the achievements of women in STEM. It is named after Ada Lovelace, the world's first published computer programmer.

Whilst we celebrate in London, other groups will organise their own events around the world, raising awareness of women’s accomplishments and inspiring girls to pursue careers in STEM, shaping a more inclusive future together.

Ada Lovelace Day would like to thank our host, the Royal Institution, and our media partner, Stylist, Redgate, The Information Lab's Data School and dxw, for their support this year. Find out more about them on the Ada Lovelace Day website.

About Helen Arney

A woman is posing with an object on her head.

Writer, science presenter, geek songstress and ‘Voice of an Angle’ Helen Arney has appeared on TV, radio and in theatres across the world with her unique mix of stand-up, songs and science. You might have seen her explaining physics while riding a rollercoaster for BBC2 Coast, electrifying Sandi Toksvig on QI, singing the periodic table on Channel 4, smashing a wine glass with the power of her voice live on Blue Peter, hosting Outrageous Acts Of Science on Discovery Channel, or touring with science comedy phenomenon Festival of the Spoken Nerd. She also features as the voice of the bubble chamber in several collaborations between artist Yu-Chen Wang and CERN, and as the voice of the Periodic Table on Amazon Alexa in the US. 

Helen is currently working on several full-length musical theatre projects about astounding women in STEMM, and has filled several notebooks with rhymes for Uranus (none of which are printable here). 

About Jennifer Rohn

A woman smiles towards the camera

Prof Jennifer Rohn is Head of the Centre for Urological Biology, University College London.

Jenny is Head of the Centre for Urological Biology in the Department of Renal Medicine in the Division of Medicine at University College London. Jenny runs a research laboratory studying urinary tract infection, an incredibly common malady that afflicts hundreds of millions of people each year and inflicts a tremendous healthcare burden. Despite this, like many diseases primarily affecting women, UTI has been historically understudied, and there have been no new therapies developed since Alexander Fleming discovered antibiotics nearly a century ago. Jenny and her team are working hard to find better ways to treat this notoriously tricky infection, where the bacteria have evolved many devious strategies to subvert our immune defences. 

A dual USA/UK citizen, Jenny earned her PhD in Microbiology at the University of Washington, Seattle USA in 1996. After a postdoctoral fellowship at the Cancer Research UK London Research Institute and a group leader position in a start-up biotech company in the Netherlands, she re-joined academia at University College London in 2006 with a Wellcome fellowship and was promoted to Professor in 2021. 

In her not-so-spare time, Jenny is also a science writer/communicator and public speaker, and frequently appears on radio, television and other broadcast and print media as a scientific expert in infectious diseases. She is the author of three published ‘lab lit’ novels about scientists (Experimental Heart, and The Honest Look, both from Cold Spring Harbor Laboratory Press, New York; and Cat Zero, from Bitingduck Press), and various published short stories. She also founded and edits, a website dedicated to scientific culture, literature and all things “geek chic”.

About Sophie Carr

A woman is smiling

Dr Sophie Carr is the founder and director of Bays Consulting. Sophie’s first love was Lego, then aeroplanes and her career followed suit. She trained as an engineer and whilst working full time took a PhD in Bayesian Belief Networks and has worked in data analytics ever since. Or to put it another way, Sophie has made a living out of finding patterns. Outside of work, Sophie is the Vice President for education and statistical literacy at the Royal Statistical Society and the World’s Most Interesting Mathematician.

About Aarathi Prasad
