Paris – Physicist and science communicator Julien Bobroff, a professor at Université Paris-Saclay, recently shared a surprisingly relatable sentiment on Instagram: a dislike for the sound of his own voice. The post, simply stating “JE DÉTESTE MA VOIX” (I hate my voice), resonated with followers, garnering over 400 likes and sparking a conversation about self-perception and the often-jarring experience of hearing oneself recorded.
Bobroff’s work centers around making complex scientific concepts, particularly in quantum physics, accessible to a wider audience. He leads the research team “La Physique Autrement” (“Physics differently”) at the Laboratoire de Physique des Solides, focusing on innovative methods of science education, and popularization. His dedication to communicating science extends beyond academic research, encompassing a significant online presence and a commitment to engaging the public with the wonders of the physical world.
The Instagram post, made on March 14, 2026, is a brief but humanizing moment from a figure dedicated to explaining the universe. It highlights a common experience – the disconnect between how we perceive our own voice and how it sounds to others. This phenomenon, often attributed to the way sound travels through the body versus through the air, can be particularly pronounced when listening to recordings.
Bobroff’s career spans decades of research in areas including superconductivity, magnetism, and condensed matter physics. He earned his PhD in 1997 from Université Paris-Sud (now part of Université Paris-Saclay) with a thesis focused on nuclear magnetic resonance (NMR) in high-temperature superconductors. His work has been published in prestigious journals such as Nature Nanotechnology and Physical Review Letters, demonstrating his contributions to the field. A 2017 publication in Nature Nanotechnology, titled “Reimagining Physics,” showcases his innovative approach to science communication.
Beyond his research, Bobroff has received recognition for his work in science mediation. He was awarded the Prix Jean-Perrin in 2011 and the Médaille de la médiation scientifique du CNRS in 2022. Most recently, in 2023, he received the Prix Roberval Grand public, acknowledging his success in bringing science to a broader audience. His website, vulgarisation.fr, serves as a hub for his various projects and provides links to his social media channels, including YouTube, where he shares educational content.
The post’s simplicity belies the broader context of Bobroff’s work. He actively uses platforms like YouTube, Bluesky, Instagram, Facebook, and TikTok to disseminate scientific knowledge. His YouTube channel, Julien Bobroff, features videos explaining complex physics concepts in an accessible manner. This commitment to digital outreach underscores his belief in the importance of making science engaging and understandable for everyone.
The Instagram post serves as a reminder that even those who dedicate their lives to understanding the universe are not immune to everyday insecurities. It’s a small, personal moment that humanizes a prominent figure in the scientific community and offers a relatable point of connection for his followers.
As Bobroff continues his work in physics research and science communication, his online presence will likely remain a key component of his outreach efforts. The ongoing development of new platforms and communication strategies will undoubtedly shape how scientists engage with the public in the years to reach, and Bobroff’s innovative approach positions him as a leader in this evolving landscape.
