My research mainly focus on vaccine preventable diseases in various aspects of epidemiology, disease surveillance, vaccine effectiveness, and economic evaluations. Currently, I have been working on pneumococcal diseases and Japanese encephalitis. My expertise in infectious disease consultation and clinical research, as well as my experience working with tropical medicine, make me well-suited to contribute to my research by providing clinical insights and expertise in clinical and epidemiological data collection, and data analysis. My expertise in epidemiology and statistical analysis, including statistical analysis methodology and sample size estimation, will be invaluable for the proposed study, particularly in the collection, curation, and analysis of clinical and epidemiological data.
