PROJECT SUMMARY/ABSTRACT (DESCRIPTION) The Case Western Reserve University (CWRU) Alzheimer’s Disease Translational Data Science (ADTDS) Training Program is designed to power therapeutic discovery by producing a new generation of scientists cross- trained in clinical research of Alzheimer’s Disease (AD) and analysis of large scale ‘omics data. Focused on predoctoral PhD and MD PhD students, this training program fills a critical gap between these disciplines in academic graduate programs. The ADTDS builds upon the Cleveland Alzheimer’s Disease Research Center (CADRC), and multiple ongoing national collaborations responsible for generating large-scale multi-omic data on diverse populations with AD. As part of this training program, trainees will: 1) Form multi-disciplinary mentorship teams to expand understanding of AD etiology and disease course through data analysis, 2) Interact with a variety of faculty who are world-recognized leaders in AD genetics, pathology, and neuroscience, 3) Access large-scale data from national initiatives supported by NIA, including the ADSP, ADGC, ADNI, and AMP- AD, to answer translational and basic research questions, and 4) Receive specialized training in responsible conduct and research reproducibility with special considerations for data science. Our cross-disciplinary training program provides strong mentoring and uses state-of-the-art data science experiences within the rich environment of the CWRU School of Medicine and its affiliated hospital systems to develop independent investigators who will lead the next generation of translational research in Alzheimer’s Disease.
