 Brief Bio

Dr. Yashiro is a PHaSER scientist in the Solar Phyisics Laboratory (code 671) of NASA Goddard Space Flight Center. He has extensive experience in Solar Physics research in the analysis of Yohkoh, SOHO, and TRACE satellites, as well as writing Interactive Data Language (IDL) software. Dr. Yashiro's research work is focused coronal mass ejections, solar flares and coronal heating.

Dr. Yashiro' has created and maintans an online catalog of coronal mass ejections which is extensively used by the solar phyisics and space weather research communities in the US and around the globe.
