In a recent publication by Genomic Psychiatry, Dr. Jeremie Poschmann of INSERM and Université de Nantes unveils his transformative journey from nursing to systems biology. His unconventional career path has significantly influenced his pioneering research into the circulating immune system. By employing multi-omics tools—genomics, transcriptomics, and proteomics—Dr. Poschmann's team investigates how immune states vary across different patient populations. This innovative methodology not only sheds light on disease heterogeneity but also holds promise for infectious diseases, psychiatric conditions, and vaccine responsiveness. Additionally, Dr. Poschmann advocates for improved research infrastructure, emphasizing the importance of stable contracts and interdisciplinary collaboration in advancing science.

Dr. Poschmann’s laboratory centers on analyzing blood-derived immune cells at the molecular level. Utilizing advanced computational techniques, his team deciphers the intricate dynamics of immune responses. Their work reveals patterns shaped by past infections, environmental exposures, and genetic predispositions, offering insights into why individuals react differently to pathogens or treatments. For instance, understanding why some people develop severe symptoms from SARS-CoV-2 while others remain asymptomatic could revolutionize personalized medicine. Through the lens of systemic readouts provided by blood samples, Dr. Poschmann envisions creating immune signatures capable of predicting disease risks or therapeutic outcomes.

Beyond scientific breakthroughs, Dr. Poschmann champions a compassionate leadership style rooted in mentorship and inclusivity. Having initially trained as a nurse, he prioritizes mindset over academic credentials when assembling his team. This approach fosters creativity and innovation within his lab. Moreover, he emphasizes the necessity of addressing structural challenges faced by researchers, particularly postdocs and support staff in Europe, advocating for long-term stability to ensure continuity in scientific endeavors.

Dr. Poschmann’s reflections extend beyond the confines of the lab. Engaging in activities such as surfing along France’s Atlantic coast allows him to balance professional demands with personal rejuvenation. He draws parallels between the perseverance required in both science and surfing, underscoring the value of grit, patience, and timing in achieving success. His narrative reflects a broader trend toward integrating diverse disciplines in modern science, aiming to bridge biological, computational, and medical domains.

This interview forms part of the Innovators & Ideas series, highlighting trailblazers who are reshaping contemporary science. By combining cutting-edge research with personal anecdotes, these profiles engage readers while educating them about the scientists influencing the future. Dr. Poschmann’s story exemplifies the potential of data-driven discovery to enhance clinical care and promote preventive healthcare models. As we strive to integrate complex data into actionable solutions at the point of care, dismantling existing barriers becomes crucial for realizing truly personalized health strategies.
