Three complementary disciplines.
Data science to advance health for all.

To understand health and disease today, we need new thinking and novel science—the kind we create when multiple disciplines work together from the ground up. Read More



The 6th Annual DBEI Research Day

February 27, 2024 (8:00 a.m. to 4:00 p.m.)

Biomedical Research Building, Glen Gaulton Auditorium
Registration for the 6th Annual DBEI Research Day is open. Researchers from the Department of Biostatistics, Epidemiology and Informatics (DBEI) will convene on February 27, 2024 to showcase and share the impact of their research with the greater Penn community. Comprised of a keynote lecture, research and faculty spotlight presentations, a poster competition, and networking, this engaging event is an excellent opportunity to learn more about how the DBEI is leading the way in the biomedical and population health data sciences, and to foster connections and future collaborations across the Perelman School of Medicine and the University. Space is limited, so register to secure a spot.

September 2023

Joel Gelfand, MD, the James J. Leyden, M.D. Endowed Professor in Clinical Investigation of Dermatology and Epidemiology, and colleagues at Penn found that adults and children with atopic dermatitis (AD) are more likely to develop inflammatory bowel disease (IBD) than their peers. In a new study published in the journal JAMA Dermatology, Dr. Gelfand and his team compared data from more than 409,000 children and 625,000 adults with atopic dermatitis and compared them to more than 1.8 million children and almost 2.7 million adults without the disease. Upon analysis, the scientists reported a “statistically significant” increased risk of incident or new-onset IBD among 44% of children and 34% of adults with atopic dermatitis, compared to the control groups.

"Less work has been done with atopic dermatitis, which is a very common skin disorder, and IBD. Both atopic dermatitis and IBD are diseases with barrier dysfunction, microbiome alterations, and chronic inflammation suggesting commonalities between the two diseases,” said Dr. Gelfand in a recent interview with Medical News Today. According to Dr. Gelfand, these findings are important for better understanding the health trajectories of people with atopic dermatitis.

Elizabeth Nesoff, PhD, MPH discusses her recently published study in the Leonard Davis Institute of Health Economics (LDI) blog investigating neighborhood features that were correlated with fatal opioid overdoses among the homeless population in New York City. Dr. Nesoff uses these discoveries to make important policy recommendations with respect to targeted outreach and other interventions.

February 2023

Jeffrey Morris, PhD and Jeffrey Gerber, MD, PhD, MSCE collaborated with researchers to examine measles serostatus among pregnant persons about to give birth and whether rubella serostatus, which is routinely assessed during pregnancy, can serve as a proxy for measles serostatus.

The DBEI distinctively brings together expertise in biostatistics, epidemiology and informatics, to advance population-health science.

About Us

To understand health and disease today, we need new thinking and novel science —the kind  we create when multiple disciplines work together from the ground up. That is why this department has put forward a bold vision in population-health science: a single academic home for biostatistics, epidemiology and informatics.
