Dr. Murakami received his Ph.D. from Kyoto University, Japan. He then worked at the
University of Colorado-Boulder, University of Michigan-Ann Arbor, University of Louisville,
among others. His expertise includes aging, stress resistance, age-related memory
impairment (AMI) and dementia in basic and medical sciences. The most significant
findings may be the roles of the insulin/IGF-1 pathway and the serotonin pathway in
aging, stress resistance and cognitive functions. In fact, the work has been widely
accepted and referred in major medical textbooks (including Harrison’s Internal Medicine;
Hazzard's Geriatric Medicine and Gerontology). His outreach internship program provides
summer course related to the work and has been repeatedly highlighted in the media
news. He has been actively mentoring students in research (10+ students per year
at TUC). His areas of teaching include Med Biochemistry, Genetics, Nutrition, Pathophysiology
and a broad range of related areas, including Gerontology and Geriatrics (see Teaching).
They fit well to his background of training (Biochem, Molec Biol, and Genetics/Genomics)
with clinical exposure. His educational role has been progressively expanding to
bridge basic sciences to clinical and patients through Gerontological Society of America,
NBOME (National Board of Osteopathic Medical Examiners) and his educational, service
and research activities.
Current research interest is to understand the transition of aging processes from normal aging to disease (including Alzheimer’s disease, AD), using semi-automated imaging systems (Machino et al., 2014) and big data analysis of dementia genes in humans and C. elegans (Vahdati et al., 2017). He has formulated the multiplex stress resistance theory of aging, which has now been extended to the middle-life crisis theory of aging. Importantly, the middle-life crisis theory predicted the outcome of one or more clinical trials in the Alzheimer's disease. Service commitment includes not limited to 7 Editorial Board/Advisory Board, 4 Executive Committees, Grant/Manuscript Reviewer and NBOME National Faculty. He is a founding organizer/director of the outreach program, Biotech Academy Touro Summer Internship, which is designed for high school and college students. The internship uses an innovative educational approach to introducing osteopathic medicine, global health and research. It has been repeatedly highlighted by media since it has been started.

Recently he accepted new national leadership roles, including Public Policy Representative
of BS Section Executive Committee (Gerontology Society of America); and Committee
and Task Force/New Comprehensive Foundational Sciences Examination (NBOME).
Significance to TUC initiatives/strategic plan:
Metabolism and Nutrition:
Our AD genes are involved in metabolism (glucose, lipid, and cholesterol metabolism) and in diabetes. The genes should reveal the role of the metabolism and diabetes genes in dementia. We include patients to obtain feedback to our research.
Community Outreach and Inclusion:
The Biotech Academy Touro Summer Internship has 94% of the intern students from the underrepresented group. It motivates students to osteopathic medicine and other areas taught at TUC.

Recent Book and Paper:
1. Murakami, S. Editor (2017) Research Topic: Biology of cognitive aging: model systems, technologies and beyond. Publisher: Frontiers Media SA. ISBN: 9782889451449 eBook
Highlight: This covers various model systems from nematodes, fruit flies, bees, snails, fishes, rodents and beyond. It has an emphasis on research toward the benefit of patients.
2. Vahdati Nia B, Kang C, Tran MG, Lee D, Murakami, S. (2017) Meta Analysis of Human AlzGene Database: Benefits and Limitations of using C. elegans for the Study of Alzheimer’s Disease and Co-Morbid Conditions. Front. Genet. 8:55. doi: 10.3389/fgene.2017.00055
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.

Highlight: Motor deficits were not well described in Alzheimer’s disease (AD). The work provides a clear evidence for motor deficits in AD model systems with neural amyloid deposits.
