My general interest is to investigate how changes in patterning mechanisms have contributed to morphological diversity.
I completed my Ph.D in the laboratory of Professor Sumihare Noji at the University of Tokushima in Japan, where I studied the molecular mechanisms underlying leg regeneration in cricket, Gryllus bimaculatus. As a postdoc in the Noji lab, my research was focused on how changes in patterning mechanisms have contributed to morphological diversity, where I studied molecular mechanisms of the cricket early embryogenesis, especially focused on cellular dynamics involved in anteroposterior and dorsoventral axis patterning.
I joined the Extavour lab in 2013 as a postdoctoral fellow, to investigate the following major questions: (1) the role of positional information and Hox genes in determining where Gryllus PGCs form in the abdomen. (2) the mesodermal origin of Gryllus PGCs: do they transition from one cell fate type to another? (3) the dynamics of PGC migration: how do the PGCs congregate to gonads in abdominal segments 3-4?
I am also interested in applying new technology for genome modification such as TALENs and CRISPR/Cas systems to investigation ofthe gene-regulation function of a cis-regulatory module in developmental evolution. Outside of the lab I enjoy participating in marathon races and hiking in natural environments.
I believe the cricket Gryllus bimaculatus is a wonderful new model organism to study not only Evo-devo, but also regenerative medicine.
I am the recipient of a postdoctoral fellowship from the Japanese Society for the Promotion of Science (JSPS).
