Epi Book Spine Poetry

Dear friends and colleagues,

In a world full of distractions and challenges, our faculty, staff, and students continue to push boundaries and deliver impactful work. A few statistics from FY25:

  • Faculty submitted 77 proposals totaling $17 million
  • We on-boarded 2 new assistant professors
  • Graduate student enrollment has held steady in the ~90 range

Beyond the numbers, we've been intentional about building community within our department. Our monthly coffee gatherings have become a cherished space for connection, where we come together not just as colleagues but as people who enjoy creating alongside one another. These gatherings have featured seasonal craft-making and, in a particularly memorable session, a trip to the Epi library where we crafted book spine poetry (pictured above):

This issue celebrates the remarkable productivity and innovation happening every day in the Department of Epidemiology. From groundbreaking research on brain health and road safety to reaffirming the safety of maternal vaccinations, their efforts speak volumes about resilience and dedication.
