Lectures on Virology and infection immunity, Ph.D. and M.Sc. graduate research


I have been working on researches on prevention measures of arthropod-borne viral diseases, particularly on dengue. My primary research goals are directed toward understanding the basis of the development of an effective vaccine for prevention measures against dengue fever. My previous projects have led to the successful development of in vitro and in vivo models for the dengue vaccine evaluation studies. The novel models have also lead to a better understanding of the immune responses induced after dengue vaccination and infection. Using these novel tools, my future plans are aimed at developing an effective and safe dengue vaccine, to contribute to the reduction of dengue disease burden worldwide.
Research activities of our group, Department of Virology, Institute of Tropical Medicine are as follows:
Field epidemiology on arthropod borne diseases in Vietnam, Myanmar, Philippines, Kenya, Nepal, Malaysia, Sri Lanka.
Vaccine and therapeutic development against dengue and other arthropod-borne diseases
Identification of factor(s) involved in the pathogenesis of dengue and other arthropod-borne diseases
Development of rapid diagnostics for dengue and other arthropod-borne diseases

With rapid globalization and changes in the population dynamics, health problems in tropical regions is changing and diversifying profoundly. Innovative measures are therefore needed to enable solutions to meet rapidly evolving needs and to provide new perspectives to develop effective control measures. In the recent decades, we have seen a surge of global infectious disease epidemics- there is an increasing need for cross-sector and collaborative efforts between different fields to rapidly address challenges and introducing effective control measures. Basic research addressing pathogenicity remains key in developing effective measures, including therapeutics and vaccines. For this reason, our research aims to bring together basic virology reach, from bench to the field, in collaboration with multinational researchers from diverse disciplinary, to explore on innovative solutions against dengue and other arthropod borne diseases.
Here, we would like to engage with students on educational and research activities in the development of effective strategies against major infectious diseases of global public health threat.
