Digital technologies have changed many aspects of our society dramatically for decades. In the era of digitalization, people have to think about new questions in a different way than before. Thus, the importance of multidisciplinary research is undisputable. Journal of Digital Life aims to be a foundation to help academic researchers, private companies, and public entities think and act across disciplines. We publish scholarly literature in social science, life science, engineering, and frontier science. Research fields of our editors and editorial board members are diversified into various areas, including, but not limited to, medicine, biochemistry, physiology, sports science, education, business management, information science, and civil engineering. By making scientific literature open to the public, we are building bridges for researchers with varied specialities.
