The Prevalence and Effects of Misinformation

Through several projects with different collaborators, I've studied the prevalence and effects of misinformation in the realms of tobacco (An empirical research can be seen here, and our theoretical piece here) and vaccines.

Our research on using narratives to correct misinformation was presented and received a top four paper award in Health Communication at the International Communication Association in Prague (2018) and is currently under review. Our book chapter on ways to measure misinformation in the realm of tobacco research can be read in the edited book Misinformation & Mass Audiences

The Framing of Pandemics:

A Crisis and Risk Communication Perspective

In my dissertation, under the guidance of Dr. Joseph N. Cappella, I looked into the coverage of different pandemic outbreaks through the lens of crisis and risk communication perspectives. Specifically, using computational automated methods, I found three themes often in use in the coverage of epidemic - the scientific, the pandemic, and the social. I examined the effects of coverage on perceptions and intentions to comply with CDC during outbreaks. 

A first paper from the dissertation, focusing on automated and manual content analysis of coverage is now available online. 

A second paper looking into the effects of real world coverage and on ways to improve upon it is now available here

The Effects of Anti Tobacco Smoking Messages

As part of my work for the Tobacco Center for Regulatory Science (TCORS) at the University of Pennsylvania we've tested the effects of graphic warning labels on tobacco packages.


Our work on the effect of vividness can be read at Communication Research, on the use of testimonial in Health Communication and in Nicotine & Tobacco Research.


Our theoretical piece on using enhanced correctives against misinformation can be read in Tobacco Regulatory Science, and our book chapter on measuring tobacco misinformation can be read in the edited book Misinformation & Mass Audiences.

Automatic Identification of Media Frames

Together with Dror Walter, I'm studying the use of framing devices in Twitter by Republican candidates during the 2016 primaries and general elections. See our methodological paper, introducing the ANalysis of Topic Model Networks (ANTMN) here. Specifically, we look at the use of strategy and issue frames throughout the campaign and its effects on audiences' reactions to tweets. 

Terrorist Organizations' Use of Media

My work with Gabriel Weimann on websites using narratives to induce support in the Basque terrorist organization ETA can be found here.
