Infectious Disease in Public Health

Welcome to the Infectious Diseases Epidemiology Group in the Department of Epidemiology and Biostatistics at the Drexel University Dornsife School of Public Health.

Our distinguished infectious disease faculty have experience in the biological, behavioral, and social aspects of infection and diseases, with work in social epidemiology and geospatial analysis of infection in urban and other regions, classic studies to unravel pathogenesis (biological path from infection to disease), identification of risk factors for acquiring infection, and predictive modeling of infection incidence that combines knowledge in all of these areas of enquiry.

We are a diverse group with interests that range from COVID-19, to healthcare associated infection (C. diff), to HIV and STI prevention, to neglected tropical diseases, to the natural history of chronic viral infections, to evaluation of vaccine efficacy and vaccine preventable diseases, to HIV clinical trials.

We hope that we can excite you about the study of infectious diseases—the etiology, modeling of incidence, and intervention design/strategies.

What is Infectious Disease?

Infectious Disease is the study of human and animal diseases caused by microorganisms.

Students studying infectious disease at Drexel University Dornsife School of Public Health take courses in areas such as microbiology, epidemiology, health surveillance and patient safety.

Why Study Infectious Disease at Drexel Dornsife?

Drexel Dornsife's award-winning faculty in the Department of Epidemiology and Biostatistics and faculty in the Department of Environmental and Occupational Health conduct infectious disease research in communities across the United States and the world. They teach infectious disease through principles and practice to students in infectious disease programs.

Today's critical need to understand infectious disease is translating into career opportunities for public health professionals. Data shows that "40% of infection preventionists are expected to retire in the next five to 10 years," according to Sarah Smathers, MPH, CIC, FAPIC, affiliate faculty and co-director of Dornsife's Certificate in the Infectious Diseases Prevention and Control.

A career in Infectious Disease means "you’re always learning. You never know everything there is to know in this field. And just when you think you do, there’s a new pathogen to learn about," Smathers told Infection Control Today about her work as a system director at the Children's Hospital of Philadelphia.

Dornsife Alumni Career Outcomes

Job titles and companies that Dornsife alumni work for include:

  • Infection Preventionist at the Children's Hospital of Pennsylvania
  • Director of Infection Prevention and Control at Temple Health
  • Epidemiologist at Colorado Department of Public Health
  • Statistician at U.S. Department of Agriculture
  • Infection Preventionist at University of Pittsburgh Medical Center

Infectious Disease Programs

Master's in Infection Prevention and Control

New! This fully online Master of Science (MS) in Infection Prevention and Control prepares students for leadership positions in the fast-growing field of infectious disease.

Certificate in Infectious Disease Prevention and Control

The fully online Certificate in Infectious Disease Prevention and Control, designed for working professionals, focuses on fundamental content in infectious disease, epidemiology and surveillance, and patient safety. Credits from this online certificate can then be rolled into the MS in Infection Prevention and Control.

"Pathogens I & II were the most comprehensive courses I've had, and they were the most impactful to my current position. I really appreciate all the work that Dr. Chernak put into the certificate courses."

-- Certificate in Infectious Disease Prevention and Control student Sara Spear

Infectious Disease and Population Health Minor

The Infectious Disease and Population Health Minor is intended to prepare students to work in the field of infectious disease prevention and control in public health, health care, and other nonprofit settings. It is open to all Drexel graduate students in all schools and colleges.

“The Infectious Disease minor prepared me and allowed me to jump right into my position.

Compared to another colleague who started around the same time, I really feel like the courses from the I minor gave me an edge. Dr. Chernak’s Microbes class and textbooks have been a huge resource for me. I also think Professor Smather’s class was a huge help since she covered a lot of the NHSN definitions and caveats through the exercises we worked on in her class.”

Core Faculty in Infectious Disease at Drexel Dornsife

Joseph Amon, PhD, MSPH

Ester Chernak is the director of the Center for Public Health Readiness and Communication (CPHRC) at Dornsife and co-director of Dornsife's Certificate in the Infectious Diseases Prevention and Control.

Her work focuses on initiatives that enhance public health and health care capacity at the local and state level, improve the preparedness of at-risk communities, build community resilience through partnerships between public health and community health care and social service organizations, and facilitate emergency risk communication.

With a background in biomedical informatics, Neal Goldstein focuses on computational approaches in complex data settings to understand infectious disease transmission among vulnerable populations including children and sexual and gender minorities. This has been demonstrated through his work in HIV, healthcare associated infections, and vaccination and vaccine-preventable diseases.

Micheal LeVasseur's primary area of research in epidemiology is in HIV and health disparities among sexual and gender minority populations.

He is also interested in the intersections of data science and public health.

Thersa Sweet, PhD, MPH

Thersa Sweet’s work prior to joining Dornsife was primarily in virology, molecular biology, and cancer biology. Since arriving at Dornsife, she has been involved in epidemiologic studies involving HIV risk in sexual minorities.

She has conducted analyses to identify increased rates of adverse mental health conditions among MSM who have been sexually abused as children—and linking these mediators to incident HIV infection or other STIs in MSM study participants.

Infectious Disease Faculty in the News

Experts in Drexel Dornsife's Infectious Diseases Epidemiology Group are routinely called upon by the media to offer commentary and analysis on infectious diseases.

For example, Neal D. Goldstein, PhD, assistant research professor, and Michael LeVasseur, PhD, assistant teaching professor, authored a guest post for the Drexel News Blog, The Pandemic Will End, but We’re Probably Stuck With the Coronavirus. Additionally, LeVasseur was recognized by New York State for his efforts to provide government officials with analyses and forecasts during the pandemic. More news articles are linked below.
