Research Contributions

My research bridges health systems strengthening, maternal and child health, and infectious disease surveillance, informed by a multidisciplinary foundation in public health science. I focus on uncovering systemic barriers to healthcare and advancing equity-driven solutions that improve outcomes, especially in underserved and resource-limited settings.

Before entering academia, I led initiatives at the San Antonio Metropolitan Health District, including the Fetal and Infant Mortality Review (FIMR) and Maternal Mortality and Morbidity Review (MMMR) programs. These initiatives focused on community-based strategies to reduce perinatal disparities, which has profoundly influenced my applied research approach. I managed cross-sector collaboration, maintained HIPAA compliance, and provided evidence-informed recommendations rooted in HRSA guidelines.

Today, my academic work continues to build on that momentum. I apply theoretical models such as the Three Delays Model, Health Care Access Barriers Model, Logic Model, Socio-ecological Model/Framework, and the International Health Regulations (IHR) to examine how legislation, geographic access, institutional readiness, and care quality influence maternal outcomes and public health capacity in multiple and diverse settings. From Alabama’s rural prenatal care access to vaccine-preventable diseases in West Africa, my research focuses on turning data into actionable pathways to inform policy and practice.

Current Research Projects 

1.       Barriers to Prenatal Care Access: A Latent Class and Mixed Methods Study on Pregnancy Intentionality 

This study analyzes how pregnancy intentionality shapes timely prenatal care engagement. Utilizing latent class analysis within the Health Care Access Barriers model, this study examines structural and attitudinal factors that influence care-seeking behavior and provides actionable strategies to promote early and equitable access for women of reproductive age. 

2.       Measles Epidemiology and Immunization Challenges in Somalia

Focused on infectious disease control in humanitarian settings, this project investigates measles transmission dynamics and barriers to immunization. It aims to generate practical insights for enhancing surveillance and vaccination strategies in the face of systemic public health challenges.

              3.         Evaluation of Tuberculosis and TB-HIV Co-infection Challenges in Fragile Health Systems. 

Augmenting broader efforts in disease control, this project emphasizes surveillance, service integration, and recovery strategies across resource-challenged and post-conflict settings to advance health security. 

4.   Evaluating Surveillance and Laboratory Capacity for Measles Control in West Africa

This study examines the impact of national surveillance and laboratory capacities on controlling measles in West African countries. Through this analysis, this research aims to provide valuable insights that can inform the development of effective regional strategies and targeted investments. The ultimate goal is to enhance readiness to manage vaccine-preventable diseases and promote healthier communities.
