Her research focuses on the feasibility of treatment-as-prevention to achieve Hepatitis C virus elimination among people who inject drugs. She is also interested in modeling fine-scale spatial and temporal dynamics of disease transmission with epidemiologic and pathogen genetic data. Kyra has collaborated closely with many public health authorities, including the US CDC, WHO, MSF, and various ministries of health to study influenza, dengue, yellow fever, Ebola, rotavirus, leprosy, and chikungunya. She has experience in the implementation and analysis of clinical trials in low-resource settings and during outbreak responses.

Kyu is a postdoctoral fellow in the Department of Epidemiology. He works primarily on child health and emerging infections. Kyu has experience with respiratory pathogens (e.g. pneumococcus, influenza) as a micro/molecular biologist and as an infectious disease epidemiologist. He is fluent in Korean and has extensive experience in Kenya and Tanzania.
 



Jowanna Malone

Jowanna Malone

Jowanna is a doctoral student in Infectious Disease Epidemiology at Johns Hopkins Bloomberg School of Public Health. She received her B.A. in Sociology and a Master of Science in Infectious Disease Epidemiology from Harvard University. Her research focuses on HIV prevention and treatment efforts among racial and sexual minority groups (particularly surrounding PrEP use). Jowanna is especially interested in how intersectional marginal identities affect one’s HIV/STI outcomes. Jowanna is currently conducting her dissertation on identifying socioecological challenges (i.e. at the individual, community, and structural level) to achieving viral suppression among men who have sex with men (MSM) in the United States. Jowanna is experienced in qualitative research methods, scientific manuscript development, quantitative data analysis, HIV and STI testing, and survey implementation.
