Her research centers on the use of large-scale longitudinal data to study health outcomes in populations underrepresented in research, particularly people aging with HIV. She focuses on comorbidities such as cardiovascular disease, cancer, kidney and liver disease, diabetes, and hypertension, and uses advanced epidemiological methods to understand the impact of HIV and non-HIV factors on multimorbidity. She has developed best practices for harmonizing data across diverse cohort studies, including NA-ACCORD and IeDEA, and has led the CIVETs collaboration to inform COVID-19 vaccination policy in people with HIV. Her work extends the HIV Care Continuum to include long-term health indicators and informs national strategies such as the US National HIV/AIDS Strategy.

Her recent publications reveal a strong trend in modeling the future burden of multimorbidity in people with HIV, analyzing breakthrough infections post-vaccination, and evaluating cardiovascular risks in aging populations with HIV and coinfections. She also investigates health disparities, transgender health, and data quality tools for global research networks.

Notable scientific awards include the NIH Office of the Director’s Award (2021), the American Journal of Epidemiology’s Overall Best Paper (2020), and multiple Johns Hopkins leadership and research awards. She is an elected member of Delta Omega Honorary Public Health Society.

Dr. Althoff leads major research initiatives including the LITE/ENCORE study on transgender women and HIV incidence, the HEALthy Brain and Child Development Study Design Working Group, and the PEARL model for forecasting multimorbidity. She is deeply committed to translating research into policy and public communication, emphasizing trust-building with lay audiences. She mentors students and early-career researchers and contributes to national and global public health policy through her data-driven insights.
