Shin Murakami, PhD, FGSA
I received PhD from Kyoto University, Japan. I then worked at the University of Colorado-Boulder, University of Michigan-Ann Arbor, University of Louisville, among others and is currently a Full Professor at Touro University-California. My expertise includes aging, stress resistance and dementia. My work on aging and stress resistance has been widely referred to in major medical textbooks (including Harrison’s Internal Medicine; Hazzard's Geriatric Medicine and Gerontology). Current research interest is anything related to genes and aging to investigate middle life the transition of aging processes and age-related comorbidities, using real-time quantitative imaging systems, systems biology and machine learning. I have formulated the multiplex stress resistance theory of aging, which has been extended to the "middle-life crisis theory of aging" (Murakami et al., 2011; Murakami, 2013). A list of publications is available at: https://www.researchgate.net/profile/Shin-Murakami/research. My national and international roles include Editor-in-Chief, Editorial Board, AFAR National Scientific Advisory, NBOME National Faculty, ACGME Task Force, among others. Areas of teaching include Medical Biochemistry, Medical Genetics, Molecular Biology and other related areas at medical and graduate schools. He is a founding director/organizer of the outreach program, Biotech Academy Touro Summer Internship, which is an innovative educational approach for high school students and early level college students. My goal is to create an outreach loop ("big-helping loop") from basic and medical sciences to the community.

Highlight: This is the first comprehensive validation of Alzheimer's disease genes. The work provides the genetic basis of AD that shows the complex comorbidities and explains why the diagnosis of AD is often difficult. The work significantly increases the number of C. elegans AD genes from 17 to more than 400 genes. Link: https://doi.org/10.3389/fgene.2017.00055
