Yesterday marked my installation as Professor at Karolinska Institutet I’m extremely grateful to my family, friends, and lab members who joined to celebrate this milestone. Excited for the journey ahead! @ki.se

Saddened to hear of Sir John Gurdon’s passing at 92. His pioneering work in nuclear reprogramming laid the foundation for modern stem cell biology. A true giant of developmental biology and an inspiration to generations. Nobel Laureate (2012, with Shinya Yamanaka). 👇🏼being grilled by him :)

Thanks @societymucosalimm.bsky.social for highlighting our work! Kudos to Francisca and Bianca for an amazing job!

This is how we experience the Nobel Prize announcement every year, with excitement! This year was extra special, as we celebrated the immunology and Treg! 👇🏼 Listening to our department prefect and lab neighbor, Marie Wahren, beautifully explaining the motivation behind this year’s #nobelprize
