AI for Maternal and Child Health: Develop and test AI applications to predict pregnancy complications and improve vaccination coverage and child development.
-
Digitalizing Health Information Systems: Examine the challenges and opportunities of implementing digital health information systems to improve data interoperability and public health decision-making.
❤️ Non-Communicable Diseases (NCDs) and Mental Health
As populations age and lifestyles change, NCDs and mental health conditions are becoming the dominant global health challenge.
-
Cancer Burden and Control: Assess the cancer burden and the effectiveness of control strategies in specific regions, such as the South-South region of Nigeria.
-
Time to Treatment and Quality of Life: Investigate the link between the time span from symptoms to treatment and the quality of life of cancer patients in different settings, like South India.
-
AI and Suicide Risk: Research the potential exacerbation of suicide risk among vulnerable populations due to generative AI.
-
Climate Change and Mental Health: Explore how the determinants of health, including climate change, inequality, and poor nutrition, are shaping mental health outcomes globally.
👩👧👦 Maternal, Child, and Adolescent Health
Protecting the health of women, children, and adolescents is a cornerstone of global public health.
-
Predicting Pregnancy Complications: Develop and validate models to predict pregnancy complications using clinical features assessed by community health workers.
-
Gestational Diabetes and Neonatal Outcomes: Examine the impact of factors like height, weight, and gestational weight gain on gestational diabetes and neonatal outcomes.
-
Early Infant Diagnosis of HIV: Research strategies to improve the uptake of early infant diagnosis of HIV in primary care settings.
-
Reserve Capacity and Adolescent Health: Explore how “reserve capacity” and other adolescent pathways contribute to socioeconomic inequalities in mortality and education across generations.
⚕️ Health Systems and Global Health Governance
A functioning health system is the backbone of any public health effort, making this a crucial area for research.
-
Health System Resilience: Evaluate the resilience of health systems in low-income countries to the convergence of climate-related shocks and chronic stressors.
-
Universal Health Coverage (UHC): Investigate the barriers to achieving Universal Health Coverage, particularly in fragile and conflict-affected states.
-
Infectious Disease Prevention in Crises: Determine the most effective combinations of interventions to increase child health in the acute phase of humanitarian emergencies.
-
Health Workforce Development: Research strategies for building a resilient and equipped multi-sectoral health workforce to prevent, detect, and respond to emerging diseases.
