Dr Bhim Gopal Dhoubhadel, MBBS, MTM, DipPaed, DTM&H, PhD

I am a physician–scientist working in the field of pediatric infectious diseases, vaccines, and global health, with extensive research experience in Japan and Nepal. My work focuses on generating clinical, laboratory, and epidemiological evidence to support infectious disease prevention, vaccine policy, and antimicrobial resistance control across diverse healthcare settings.

​​

From 2015 to 2024, I held academic appointments at Nagasaki University as Assistant Professor and subsequently Associate Professor at the School of Tropical Medicine and Global Health and the Institute of Tropical Medicine. During this period, I contributed to teaching and academic supervision across diploma (DTM&H), master’s (MPH, MSc, MTM), and doctoral (PhD) programs. My teaching and supervision covered clinical tropical medicine, infectious disease epidemiology, vaccine evaluation, and research methodology, with a strong emphasis on quantitative and translational research.

​

My research work spans pneumococcal disease, pneumonia, typhoid fever, antimicrobial resistance, and vaccine effectiveness, and has contributed to the peer-reviewed literature in international journals such as The Lancet Infectious Diseases, Emerging Infectious Diseases, Thorax, Vaccine, Vaccine X, Vaccines, and Tropical Medicine and Health. A central focus of this work has been the infectious disease epidemiology and evaluation of real-world impacts of vaccines in Nepal, alongside complementary studies of adult in Japan.

​

​One of my research interests is the development and application of high-throughput laboratory assays for epidemiological studies. This includes nanofluidic real-time PCR–based assays for simultaneous detection and quantification of up to 70 pneumococcal serotypes from a single sample, as well as 24-plex microsphere-based immunoassays to quantify serotype-specific antibody responses against 24 common vaccine serotypes. These methodological approaches support large-scale vaccine impact and immuno-epidemiological research.

​

I currently serve as Director of Research at Siddhi Memorial Hospital in Nepal, where I support ethically conducted clinical research and the integration of research evidence into local health practice, while continuing collaborative work with academic partners in Japan and internationally.
