The 7th International Symposium on Isotopomers 2014 (ISI 2014) will be held on July 1-4, 2014 at Tokyo Tech Front in Ookayama, Tokyo, Japan. The purpose of ISI 2014 is to look into the latest scientific achievements in the measurement and analysis of isotopomers, from planetary science to new applications in environmental and life sciences including food authenticity and biomedical research. Historically, the symposium receives strong contributions from the field of mass-independent fractionation, site-specific distrobitions, and multi-substituted isotopomers measurements, but conventional isotope studies still form a part of the program. PI Naohiro Yoshida is the president of ISI and the initiator of its first symposium held in Yokohama in 2001.
