Science communication is the discipline that studies anything related to communicating science.
I do my best to communicate science.
I do my best to communicate science to non-scientists, and I also do my best to communicate with scientist from other fields.
We visits all kinds of events to share our citizen science project, the Tick App, and recruit neighbors.
When speaking and writing you target your audience. This is also the case in online communications. Many online communications are available to anybody and therefore I target an in-between audience. The level of communication is above 8th grade (the average US-reading level), but I try to avoid jargon or at least explain the gibberish words.
For example: I (try to) maintain a blog containing notes about my research, and work-related life. In addition, this website does not have the traditional scientist style and on Twitter you will find a similar voice.
Science speak is almost like a different language. Similar to most languages, every science discipline has its own dialect. People speaking different dialects don't necessarily understand each other. An ecologist can have trouble understanding an epidemiologist, and a veterinarian can confuse engineers in a heart beat. I do my best to bridge these gaps. *
