    Collapse overview
    Dr. Clelland, PhD, MD, MPhil, is an Assistant Professor in the UCSF Department of Neurology. As a neurologist, she specializes in caring for patients with dementia and cognitive symptoms at the UCSF Memory & Aging Center. Her lab at the UCSF Weill Institute for Neurosciences develops novel therapies for neurodegenerative diseases. Her current work centers on creating novel CRISPR gene therapies for genetic forms of neurodegenerative diseases such as frontotemporal dementia (FTD), Alzheimer's disease (AD), Parkinson's disease (PD) and amytrophic lateral sclerosis (ALS). Her lab utilizes patient iPSCs to model disease, advanced sequencing technologies and cutting-edge CRISPR technologies to develop first-in-class gene therapies for CNS diseases. The Clelland lab is committed to promoting equity and justice in science in medicine. One of the pillars of the Clelland lab is the mentoring and advancement of trainees from underrepresented backgrounds to become the next generation of scientific leaders.

    Altmetrics Details PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication.
