The 21st annual Public Health Research Day conference is hosted by Brown University’s School of Public Health and highlights the research accomplishments of our students, trainees, and partners across campus. One of several events held to celebrate National Public Health Week, April 6-12, 2020, the poster session encourages interaction among members of the greater Brown community and external partners. After the Conference, an awards ceremony acknowledges winners in four categories: Best Undergraduate Poster,Best Master’s Poster, Best Doctoral Poster, and Best Post-doctoral Trainee Poster. The poster session will begin at 1:30 pm and the awards committee will begin reviewing posters at that time. Visitors are encouraged to discuss posters with students, fellows, staff, faculty, and affiliates. We expect approximately 100 posters.
