    Dr. Ayers is committed to getting the public back in public health, by harnessing big media data (including Internet search queries, news media, social media, and online networks) to listen to the public voicing their health needs in near real time. Beginning in 2011 he showed electronic cigarettes were the most popular smoking alternative on the market, being the first to predict their rise. This study has been followed by several examples of unique discoveries making public health science more responsive to the public and more effective in the process. For instance, his recent JAMA Internal Medicine report describing how Charlie Sheen’s HIV-positive disclosure prompted record-levels of public engagement with condoms, HIV symptoms, and HIV testing was covered in more than 6,000 news outlets and trended on both Facebook and Twitter. The publication of this report was later linked to a significant increase in HIV testing and made more impactful by partnering with several medical device makers to implement follow-up campaigns encouraging at-home HIV testing and condom use. His work has also been trans-disciplinary (e.g., he has published with more than 60 different collaborators, from more than 50 different research institutes representing many fields, such as applied mathematics, climatology, communications, computer science, economics, engineering, political science, sociology, and more). Dr. Ayers has published more than 60 peer-reviewed articles and several commentaries/op-eds, many of which rank in the very top of Altmetric’s research rankings (including one study that ranked among the top 1,000 most circulated articles of all time). He has an h-index of 26 (26 publications with 26 or more citations). Dr. Ayers is a frequently featured expert in the international media, including coverage in traditional news (e.g., ABC, BBC, CBC, CBS, CNN, Fox, NBC, NPR, etc.), tech or business focused news (e.g., Bloomberg, Forbes, Popular Science, Scientific American, Wired, etc.), and entertainment news (e.g., Dr. Drew, Dr. Oz, Perez Hilton, Rolling Stone, Saturday Night Live, etc.). Dr. Ayers is committed to promoting rapid improvements in public health science and leveraging public health science to save lives.
