I am Louis Gros, a Swiss medical oncologist specializing in early-stage lung cancer screening and treatment. I completed a two-year fellowship with Professor Claudia Henschke’s lung cancer screening team at Mount Sinai, New York, while maintaining ties with the CHUV (Lausanne). Now back in Switzerland, I collaborate with Professor Solange Peters, Head of Thoracic Malignancies and former ESMO President. As a clinician, I care for patients daily and actively contribute to lung cancer research. My work focuses on bridging clinical care and public health innovation, including Lausanne’s pilot screening project to address the urgent need for early lung cancer detection.

With a Master of Science in Public Health, I work as a Project Officer in the Prevention and Information Department at the Danish Cancer Society. My work centers on behavior-changing communication, developing targeted initiatives to increase screening participation and improve timely detection among individuals with low engagement. I specialize in qualitative research, conducting focus groups to explore barriers, perceptions, and motivations related to screening participation. Recently, I published an article on attitudes toward risk-stratified breast cancer screening in Denmark.

A registered nurse with a Master’s degree in Nursing Science, I am currently pursuing a PhD in the Humanities and Social Sciences of Medicine and Health. My professional and academic journey reflects a strong interest in public health, particularly in improving access to secondary prevention programs. My research focuses on identifying factors influencing adherence to screening interventions, with the goal of optimizing their effectiveness and acceptability among target populations.
