Right now I am working on several things, all related to the health of the democratic public sphere.  One line of work involves social influence in collective behavior. It's been clear for a long time that digital media facilitate citizen-driven mass behavior in which formal organizations play different roles than they did in the mass media era and before it. In addition to continuing to write about these structural changes in the way mass behavior works, I'm trying to understand better how this affects who gets involved in public life and who does not. This involves understanding who is most likely to be affected by peers and social influence. 

Another line of research involves political homophily, which is the tendency to prefer to be associated with people who have similar political values and views. Related to this is selective exposure: the tendency to prefer news that reinforces one's attitudes and opinions.  

I've also jumped into analysis of "fake news" and am trying to understanding which people take steps to verify suspect news claims and which do not.  My research here compares the US, UK, and France.

Here are some recent articles about these topics.
