🎨 After lunch we had some team-building fun with a sciency embossing workshop 🧑‍🎨 so many creative scientists in the room! Huge thanks to Asma for teaching us a new skill!! #CIOawayday #embossing

🧪 We continued with an engaging afternoon poster session featuring more of our talented PhD students 🐣 Fantastic science, thoughtful questions, and great discussions all around. The future is bright! #CIOawayday

🐣 We followed with our Junior PIs telling us about their questions for the next 5 years 💡 Lots of exciting, cutting-edge new ideas that will hopefully materialise soon and bring even more new questions to #CIO 🤓 🥳 #CIOawayday @galvez-cancino.bsky.social @mjwsim.bsky.social

🌟 Fantastic morning poster session from our DPhil students 📚🧫 so much talent and fresh thinking on display! More to come this afternoon. #CIOawayday

✨ Kicking off #CIOawayday with our senior PIs sharing the experiments that changed their careers 🧑‍🔬👩‍🔬🧫 A reminder that serendipity, curiosity, and pub chats can spark groundbreaking ideas 🤓 Clearly science thrives on kindness and collaboration and we got a lot of that in #CIO 😉🙃 #ScienceLife
