Closing the Diagnostic Gap: Leadership, Equity, and Global Health with Devasena Gnanashanmugam
In this episode of She Leads Biotech, I sit down with Devasena Gnanashanmugam, VP of Medical Affairs at Cepheid, for a deeply thoughtful conversation about diagnostics, equity, and what it really means to lead in global healthcare.
Devasena’s journey spans medical training in India, pediatric infectious disease at Stanford, work at the NIH, and now industry leadership in molecular diagnostics. But at the center of it all is one consistent mission: improving access to timely, accurate diagnosis for the patients who need it most.
We talk about tuberculosis, HIV, COVID, and the persistent global diagnostic gap — and why identifying the problem correctly is often the most powerful intervention of all.
This episode is about science, yes. But it is also about humility, collaboration, and the responsibility that comes with leadership.
