David Dowdy[Email]

David Dowdy is the B. Frank and Kathleen Polk Assistant Professor of Epidemiology at Johns Hopkins. His primary research explores the epidemiology, dynamics, and economics of TB diagnosis and treatment. David finished his MD/PhD at Hopkins and a residency in internal medicine at UCSF before returning to the faculty at Hopkins in 2011. He is a member of the steering committee of the Gates Foundation's TB Modeling and Analysis Consortium (TB-MAC), sees patients in internal medicine at East Baltimore Medical Center (an urban outpatient clinic), and receieved the International Union Against TB and Lung Disease's 2012 Young Investigator Award. David has particular interests in mentoring a new generation of TB modelers, exploring relationships between biology and human behavior with respect to diagnostic testing, seeing the outdoors, playing tennis/basketball, and expanding the Moshi Monster collection of his 9-year-old daughter, Chesapeake.

Maunank Shah[Email]

Maunank Shah is an Assistant Professor in the Division of Infectious Diseases, Center for TB Research at Johns Hopkins University. Maunank previously completed his MD at UCSF and residency in internal medicine at Emory University, where he served as Chief Resident at Grady Memorial Hospital. He subsequently completed an Infectious Disease fellowship at JHH, and PhD in Clinical Investigation at JH School of Public Health and joined the faculty in 2010. He remains active clinically and serves as an attending physician on the HIV/ID service at Johns Hopkins Hospital, and is Medical Director for the Baltimore City Health Dept Tuberculosis Program. He has a particular interest in implementation research, including evaluating the cost-effectiveness and population impact of novel TB diagnostic and case-finding strategies. To this end he is increasingly engaged in TB modeling, and has received an NIH K23 grant to study emerging TB diagnostic tests and strategies in resource-limited settings. He has additional interests in medical education and mentors public health and medical students and serves as Co-Director for the microbiology and Infectious Disease block at Johns Hopkins Medical School.

Postdoctoral Fellows

Alice Zwerling[Email]

Alice Zwerling is a post doctoral fellow working with Dr David Dowdy at the Johns Hopkins Bloomberg School of Public Health. Her current research projects include TB diagnostics and treatment evaluations with a focus on economic evaluations and modeling TB control interventions. Other research interests include understanding the dynamics of TB transmission. Alice holds a PhD in Epidemiology from McGill University, Montreal, Canada and an MSc in Epidemiology also from McGill University. Her doctoral research focused on the evaluation of Interferon-gamma release assays for use in screening health care workers for latent TB infection in both high and low TB incidence settings. Previous work in TB include projects bridging molecular epidemiology and geographic distribution of TB and The BCG World Atlas.

Colleen Hanrahan[Email]

Colleen Hanrahan is a post doctoral fellow in Epidemiology working with Dr. David Dowdy. Her current work focuses on operational research on the implementation and patient impact of new and existing TB diagnostics as well as active case finding approaches for TB. She is also interested in economic evaluation of TB control interventions. She received her PhD in Epidemiology from the Johns Hopkins Bloomberg School of Public Health, and her dissertation examined the patient impact and cost effectiveness of the introduction of a new diagnostic test for MDR-TB in South Africa. Colleen has spent 3 years living in South Africa, and brings a wealth of “on the ground” research experience as well as a deep love for the African continent. She also holds a MS degree in microbiology and firmly believes the world belongs to bacteria and humans just live in it! In her spare time, she enjoys running and adventurous cooking.

Parastu Kasaie[Email]

Parastu Kasaie is a PhD candidate at the department of Operations, Business Analytics and Information Systems, University of Cincinnati. Her research interests include simulation modeling and analysis of infectious diseases, and her current research focus is on agent-based simulation of Tuberculosis epidemics.

Andrew Azman[Email]

Andrew Azman is a post doctoral fellow in the Department of Epidemiology at Johns Hopkins Bloomberg School of Public Health. Andrew shares his time between working on studying the 'slow' dynamics of tuberculosis and much 'faster' enteric diseases like cholera. Andrew's general interests lie in understanding how complex computational and statistical models can inform smart disease control policy. In addition to spending time in front of the computer, also works on the design of empirical studies to help further our understanding of disease dynamics and control. Andrew received his PhD in Epidemiology and an MHS in Biostatistics from Johns Hopkins University in 2014. Prior to becoming an Epidemiologist, Andrew was an environmental engineer working on water and sanitation related issues.

Graduate Students

Liza Bronner[Email]

Liza Bronner is a PhD Student in Infectious Disease Epidemiology at Johns Hopkins Bloomberg School of Public Health. Liza is completing her doctoral research with Dr. David Dowdy by studying patient pathways to care and practitioner practices for diagnosing TB in the private sector in India. This study combines her primary research interests of TB diagnostics, implementation science, patient access to care and operational research. Liza completed an MPH in Global Epidemiology from Emory University Rollins SPH in 2010. Prior to starting at JHU, Liza worked with the U.S. CDC doing operational TB research in South Africa. Liza's other interests include the evolutionary aspects of infectious diseases, hiking, cooking, and chatting with friends.

Kristen Little[Email]

Kristen Little is a PhD student in the Infectious Disease Concentration at the Johns Hopkins Bloomberg School of Public Health’s Department of Epidemiology. Her current research is focused on the yield and cost-effectiveness of active case finding strategies for TB in high- and low-prevalence areas of South Africa. Kristen completed her MPH in Global Health at Emory University, and spent several years as an Epidemiology Assistant and Fellow at the Centers for Disease Control and Prevention, where she worked on perinatal HIV transmission and neglected tropical disease research.
