Research Summary

The Bharti lab investigates the underlying links between humans, pathogens, and the environment. We work to identify the mechanisms that give rise to heterogeneities in host disease burden and risk across scales, across spatial and temporal scales. We study the dynamics of host-environment interactions that drive movement and contact patterns as they relate to to pathogen transmission and access to health care.

News Articles Featuring Nita Bharti

Vector-borne diseases shaped human history and reveal race disparities

Vector-borne diseases (VBDs), such as plague, malaria and yellow fever, have significantly shaped society and culture, according to an international team of researchers. In a study published in Ecology Letters on Jan. 27, the team used historical evidence interpreted through an ecological lens to illustrate how VBDs have influenced human history, with particular attention to how VBDs have reinforced and exacerbated racism.

Take Note: Epidemiologist Dr. Nita Bharti On Safety And Effectiveness Of New COVID-19 Vaccines

The COVID-19 vaccine is slowly rolling out across the country. Some people still have concerns about these new vaccines and their safety.

Can the NBA win its rematch with COVID-19?

As the pandemic wreaks havoc on the NCAA and NFL, the 2020-21 NBA season offers new hopes and fears

Football is back in Happy Valley. The Coronavirus never left.

Not quite a mile form Beaver Stadium, there's an off-the-grid building encircled by a tall metal fence. Surrounded by fields, unmarked on maps, it looks like a tiny jail north of the Penn State campus. The gate is locked.

Heading down to the Linc Sunday for the Ravens-Eagles game? Here’s what you need to know

So you’re an Eagles season ticket holder who opted in for 2020, instead of deferring for a year, and then you secured a “pod” of two to six tickets to Sunday’s game against the Baltimore Ravens — the first game this season in which fans will be allowed at Lincoln Financial Field. What can you expect?

The NFL expects to play a full season despite coronavirus concerns

Training camp amid the pandemic went better than even some of the most optimistic NFL observers would have predicted, with the league’s COVID-19 reserve list dwindling steadily from 66 players at the end of July to fewer than half a dozen as the week of the season openers arrived.

Measles outbreaks in Niger linked to rainfall and temperature, study finds

Rainfall and temperature drive agricultural activity, which, in turn, influences patterns of measles outbreaks in the West African nation of Niger, according to an international team of researchers. The findings may be useful for improving vaccine coverage for seasonally mobile populations within Niger and other countries.

Faculty funded to study how people's movement impacts COVID-19 transmission

Nita Bharti, Lloyd Huck Early Career Professor and assistant professor of biology at Penn State, and her collaborator Anthony Robinson, associate professor of geography at Penn State, have been awarded seed funding from the Huck Institutes of the Life Sciences at Penn State to study how monitoring the movement of people can potentially be used as a predictor or early indicator of COVID-19 transmission and guide health policy decisions.

Penn State is about to turn Centre County into a massive coronavirus research project

Tens of thousands of students are scheduled to return to Penn State’s main campus in central Pennsylvania next month, swelling its host county’s population by more than a third. And during a historic public health crisis, that’s a research opportunity.

Huck Institutes tackles pandemic with true 'We Are' spirit

For faculty, staff and administrators working across Penn State’s Huck Institutes of the Life Sciences, the idea that the whole is greater than the sum of its parts is more than an abstraction. It’s an everyday reality.
