Hello, world

I am Dr. Samuel R. Mendez, a researcher and artist focused on media, technology, and science communication. I recently got my PhD in public health from Harvard. And I have a background in media arts and media studies. I aim to support better science communication online. I do that through research, teaching, and media technology. Here are some highlights:

• A study of public health agencies using Twitter, from 2012 through 2022.
• Digital Safety Kit for Public Health: A guide to decrease the harm of online harassment.
• "Public Health 🛟" feed on BlueSky
