Flu vaccines can be something of a shot in the dark. Not only must they be given yearly, there's no guarantee the strains against which they protect will be the ones circulating once the season arrives. Read More
PROVIDENCE, R.I. [Brown University] -- Tuberculosis is the leading cause of death among HIV-positive Ghanaians, with one study blaming TB for 57 percent of HIV-related deaths in the mid-sized West-African nation. To tackle the problem, a partnership between Brown University and the University of... Read More

Back in 2013 I built a Wall of Polio in my laboratory – a large stack of six-well cell culture plates that have been used to measure the concentration of polioviruses in various samples by plaque assay. It became a focal point of the lab at which many guests came to have their photographs taken.... Read More
