Introduction In recent years, few areas of biomedical science have generated as much excitement as the study of the human gut microbiome. Once viewed simply as a collection of commensal organisms inhabiting the gastrointestinal tract, the microbiome is now understood to be a dynamic and complex ecosystem that profoundly influences human health. Significant advances in […]Continue Reading

Introduction The reason I chose to work as a Medical Science Liaison (hereafter MSL) was never just the science. Coming from a background in nursing science, I have always been driven by the question of how scientific advances translate into better care for patients. Having now worked in the pharmaceutical industry for some time, I […]Continue Reading

Medical Affairs generates enormous value. Every day, Medical Science Liaisons have high-quality scientific conversations with clinicians who shape practice, influence peers, and test evidence against reality. Few functions in pharma have this level of access, trust, and depth. And yet, much of the potential value from these interactions is quietly lost. Not because MSLs are […]Continue Reading
