Hi, I'm Merriah Croston!

  • I’m a PhD student in the Public Health Sciences program at Washington University in St. Louis.
  • I study health information and health behavior diffusion with an emphasis on social media contexts.
  • Current projects use social network analysis and visualization to examine COVID-19 misinformation diffusion compared to other information types on Twitter.
  • I look to collaborate with scholars with interest in influence, information or behavior diffusion, and social media.


  • MPH (2014): Epidemiology (Emory University)
  • BS (2006): Biology (Georgetown University)
