Dr. Deiner is co-Investigator on NIH (R01/R21) and other grants using search, social media, mobile health, deep learning, digital surveillance, and large clinical registry datasets to remotely study infectious, inflammatory, pediatric, and age-related eye conditions.  His team has found significant correlations of social media data (Twitter, Google Search, Wikipedia) with clinically validated seasonality of eye disease and with detection of worldwide ocular epidemics.  They have studied the potential impact of the COVID-19 pandemic on global eye health and on other communicable disease, using search and social media.  They have begun using deep-learning analysis of social media images to validate reported disease. They also have recently begun use of targeted social media campaigns to identify and recruit study subjects for interactive components of their digital surveillance studies.  Dr. Deiner is also a Research Associate in the department of Ophthalmology, at the San Francisco VA Medical Center.
