Just after the summer holidays, I attended a summer school on data assimilation and its applications in Brasov, Romania. I really appreciate that The National IOR Centre of Norway sponsored all the expenses for the summer school. The lectures were closely relevant to my research. The lecturers were all specialists in the field of data assimilation. My classmates were from all over the world. Most of them were PhD students. During the two-week study, the discussions with the lectures and students inspired me a lot and gave me many ideas for my further research. Brasov is a lovely and beautiful city. Hundreds of restaurants and bars are along the main street of the old city centre. Our free times were full of activities. We went to a Karaoke night at an Irish pub one night, visited the Peles Castle and hiked in the mountain areas at the weekend. It is the IOR Centre that provided me the great opportunity to have so much fun while studying.

Two weeks ago, I was honored to present my research to an Indonesian delegation who visited the IOR Centre. It was my third time to present my research on behalf of the IOR Centre. Thanks to so many times of presentations, I become better and better to explain my research to the audiences, especially those who are not familiar with my field of research. Also because of the IOR Centre, I have the chances to meet researches from other institutes and from other countries.

After almost one year of taking courses and reading literatures, my research is gradually developing along the right lines. Recently, I am busy in writing my very first paper. The paper is on the stochastic information packet (SIP). A SIP is an array of possible values of an uncertain variable, representing the distribution of the variable. The traditional treatment of an uncertain variable, where the variable is represented by its average, may lead to severe mistakes during decision making. This is termed the flaw of averages. The use of SIPs can correct the flaw of averages and make it easier to communicate uncertainties, calculate with uncertainties and certify uncertain estimates. At the meantime, I am preparing for the second paper.

Having fun while working hard! It is the impression of my first year as a PhD student at the IOR Centre
