He has received awards from the Ministry of Health, American Academy of Neurology, World Federation of Neurology, and Havana School of Medicine. University College London awarded him a training experience on Global Mental Health. Llibre created and oversaw the Cognitive and Behavior Research Unit at the National Institute of Neurology in order to help meet the needs of the aging population and was tapped to help in the National Strategy for Dementia and Alzheimer Disease. Llibre was funded by the World Federation of Neurology to develop a dementia-training program for health care providers in Cuba. He joined the Global Brain Health Institute at the Memory and Aging Center, UCSF, where received fellowship training in Behavioral Neurology and Global Mental Health. His research focuses on health disparities in dementia, biomarkers, and neuropsychology of Alzheimer’s disease. Recent work focuses on the influence of African Ancestry markers on cognitive decline in AD.

Davis C Ryman, MD PhD

Vice President, Clinical Development
Levo Therapeutics

Skokie, IL 60077-1047

Email: dryman@levotx.com

After working with Dr Bateman on the DIAN OBS study and associated ADAD research projects during research rotations in his final two years of neurology residency, Davis became the first DIAN-TU Clinical Research Fellow from 2013-14. He learned a great deal about design and execution of clinical trials throughout this experience, which he has continued to apply to research in other rare neurological disorders.

From 2014-17 he worked as Medical Director at AbbVie Pharmaceuticals, where among other projects he partnered with C2N Diagnostics to initiate the first clinical trials of an anti-tau monoclonal antibody for treatment of sporadic AD and progressive supranuclear palsy (PSP). In 2017 he became Executive Medical Director at AveXis, one of the first gene therapy companies to achieve clinical success in developing an AAV9 gene therapy for spinal muscular atrophy, the most common genetic cause of infant death. Following acquisition of AveXis by Novartis in 2018, he became Vice President of Clinical Development at Levo Therapeutics, where he is currently working on development of symptomatic and disease-modifying therapies for Prader-Willi syndrome, a currently untreatable orphan disorder linked to loss of function of a paternally imprinted region on chromosome 15.
