About me

  • I specialize in the epidemiology of chronic diseases and healthcare utilization. 

  • With expertise in leveraging nationwide health databases, including claims data, electronic health records (EHR), and disease registers, I focuse on improving the care for patients with chronic conditions, specifically Chronic Kidney Disease (CKD) and Rheumatoid Arthritis (RA). 
  • More precisely, my research aims to deconstruct the care processes, analyze the disease and care trajectories and address the modifiable determinants for optimal care at the patient, health professional, and system levels.

    I have specific methodological interests in trajectory analyses, integrating and linking data of various sources, and enrich my research with qualitative approaches.
