Current Projects

AI Agent Ecosystems and AI-Human Scientific Workflows

Goal: Study how AI agents, governed collaborative memory, oversight, and human-in-the-loop workflows shape scientific reasoning

Methods: AI-human interaction analysis, agentic research workflows, collaborative memory governance, audit design, and evaluation of AI-supported scientific cognition

Impact: Positions the lab at the intersection of AI-human interaction, agent governance, scientific decision support, and applied epidemiology.

Spatial Shifts in HIV Epidemics in Sub-Saharan Africa

Goal: Identify and characterize evolving HIV hotspots across multiple African countries

Methods: Geostatistical interpolation, Bayesian smoothing, HIV care-cascade mapping, and AI-supported evidence synthesis

Partners: University of Cincinnati, Harvard, local ministries of health

Output: Targeted maps for national program use; publications in Lancet HIV, BMJ Global Health

RTRI for Precision Public Health in Sub-Saharan Africa
Funding: NIH (2023-2027)

Goal: Use rapid tests for recent infection to support precision public health strategies amid changing HIV epidemiology

Methods: Recent-infection indicators, spatial risk mapping, implementation analytics, and dashboard-oriented translation

Impact: Supports next-generation HIV hotspot targeting and program adaptation in sub-Saharan Africa.

Health Service Access and NCD Burden in HIV-Endemic Regions

Goal: Analyze joint burden of HIV and non-communicable diseases using population-level geospatial data

Methods: Hotspot mapping, spatial autocorrelation, multilevel modeling

Use Case: South Africa, Zambia

Past Projects (Selected)

Mapping HIV Testing Gaps in Zambia

Identified critical spatial disparities in HIV testing using DHS data. Supported targeted resource allocation for provincial health planners.

Geospatial Modeling of Malaria-HIV Co-Infection

Developed one of the first mechanistic models for disease interaction at a systems level. Helped shape understanding of interdependent disease burdens.

UNAIDS 95-95-95 Progress Mapping

Created fine-scale geospatial analysis of ART access, diagnosis rates, and viral suppression. Published results directly influencing subnational HIV programs in SSA.

Epidemic Metric Index for HIV

Proposed and validated new epidemiological indicators to prioritize intervention zones. Widely cited in strategy documents and used in dashboarding projects.
