  • When you want travelling, but could not.

    A selection of short documentary movie and editorials I've been made while travelling :

    Longest long house in malaysia! , said. uma belor

    Kayan language speaking people dwell in this beautiful long stretched house. Uma Belun(Belor) Leodian, Sungai Asap, Sarawak, Malaysia length = 625m (claimed 1km) This is a one of the resettlement of bakun hydraulic power project in 1990's. In Sungai Asap village, there are 15 long houses includes this one, and all are built by government. Lands for fields also provided, but people claimed that it is not enough for their next generations. This video is to introduce their environment and atmosphere there. It takes 2hours car ride from bintulu. Also operates some home-stay which is very nice. If you are interested in their culture and modern history, society, definitely you should try. I had 3night and 4 days there.

  • What I Do

    Enthusiastic engineer working on how to manage zoonotic infectious disease such as knowlesi malaria using drone, IoT, manipulation, sensor technology.

    • Multidisciplinary approaches to strengthen vector borne disease transmission study
      Vector borne disease study has been suffered due to insufficient researchers working on vectors, and is becoming incompatible with emerging infectious diseases. By introducing various new technology such as 3D printing, IoT, micro-climatorogical survey, I have been active on optimising field monitoring of mosquito activity and calling attention of researchers to join to this field of research from related fields of study.
    • Updating and sharing drone technology for field sciences

      By develop, maintenance, utilize survey technologies applicable with drone, I have been active to introduce new types of observing and sampling ecological data which has been innaccessible to the field sciences, then expand the region of non-human-centric knowledge and findings. I have been co-organizing research group on this topic which has more than 1000 membership.
