Dr. Lertmemongkolchai has spent the last 25 years working on neglected tropical diseases, specifically melioidosis and more broadly sepsis and diabetes mellitus. Her core expertise is in human cellular immunology, and her laboratory has underpinned major collaborative research with international collaborators in 14 countries worldwide to study human cellular immunology, host-pathogen interactions and biomarker research by analyzing human immune functions, blood signatures from whole genome expression profiling, large scale T cell epitope mapping and B cell epitope discovery. Her research group has expanded the studies of human cellular immune functions in response to Burkholderia pseudomallei, non-tuberculous mycobacteria (NTM) and TB, particularly pro-inflammatory cytokines, cytokine producing cells, memory T and B cells, primary macrophages and neutrophils in the context of diabetes mellitus, anti-diabetic medication, haemoglobinopathies and elderly in times of PM2.5 with increasing rates of antimicrobial resistance leading to host susceptibility to the infections.
