Self-introduction message

Contemporary biomedical research is characterized by ground-breaking discoveries and revolutionary technologies. One of the feats of the century, CRISPR-Cas9 technology, undeniably changed the way scientists study life in the planet and gives us the power to manipulate the central dogma of molecular biology.
It enables us to elegantly study the functions of the "working molecules" of the cell - the proteins - bridging the unseen submicroscopic world with the observable phenotype and physiology.
To learn the process and applications of the gene-editing technology for molecular tagging of our protein-of-interest is one of the objectives of my research at Keio University School of Medicine and KGRI. It is my academic career objective to acquire and utilize novel innovative techniques for the study of biomolecular mechanisms in glial cell biology, metabolism, and stress signaling.
