Research Interests

How stars like our Sun are formed? How life comes about? These are the questions continuously being asked by every one of us but not fully solved yet. My research is related to the understanding of the formation of stars, namely the condition and early evolution during their formation, particularly for stars much more massive than our sun. I am also interested in the chemical environments which massive stars are formed from and which they consequently shape. The large amount of dense and hot molecular gas in massive star forming regions provides us an access to probe the interstellar chemistry in warm conditions, especially for those minor but interesting organic trace species. In order to facilitate and achieve these research goals, I am involved in developing software tools for millimeter and submillimeter interferometric observations as well as for molecular line radiative transfer.
