Current Lab Members:




Claire Clelland, PhD, MD, MPhil

Primary Investigator


Dr. Clelland is a physician scientist. As a neurologist she treats patients with cognitive symptoms and dementia in the UCSF Memory & Aging Center. As a scientist she is devoted to developing treatments for neurodegenerative diseases and the patients she sees in clinic, and mentoring trainees and students. She is parent of two young children.

Dr. Clelland grew up in a small town in Oregon. She graduate from the University of Portland with a BA in biology and a BS in Philosophy. She completed her PhD through an international collaboration she established between Rusty Gage's lab at the Salk Institute and Roger Barker's lab at the Cambridge Centre for Brain Repair. She then went on to medical school at UCLA and residency at UCSF in neurology. Her graduate work was funded by a Jack Kent Cooke Foundation Fellowship for high achieving low-income students and a Marshall's Scholarship from the Marshall Aid Commemoration Commission.

About science she says: “Understanding the human brain is the next great scientific frontier. Our lab thrives in the Bay Area surrounded by our collaborators and fellow leaders in CRISPR technologies and dementia research, the rich biotech and venture culture, and from the dedication of the amazing trainees that strive to further our shared vision of curing diseases of the brain."


Bankole Aladesuyi Arogundade, PhD

Postdoctoral Scholar

Dr. Aladesuyi was born in Peterborough, England and immigrated to America when at 4 years old. Although he lost his English accent, he had great experiences in Illinois, such as  discovering his passion for understanding how our biology affects our lives as a psychology undergraduate major at the University of Illinois at Urbana-Champaign. He received his PhD in 2020 from UC San Diego Neurosciences Graduate Program. His PhD work in the Ravits lab focused on unraveling some of the mystery surrounding multiple pathological markers of disease like RNA foci and misfolded proteins caused by the C9orf72 mutation that are central to C9-FTD/ALS pathology. He is now turning his attention towards modeling disease using iPSC-derived neurons from patients, and investigating how gene editing approaches can be translated into effective therapies. Although visiting only once, Bankole feels strong ties to his family’s native Lagos, Nigeria and he hopes that his work will take him aborad in the future to have a positive impact on people from diverse backgrounds and the African diaspora.

What sparks Bankole’s scientific interest: I believe our recent progress in understanding how genetics influence disease and the newly accessible tools to correct genetic mutations will soon empower us to create a cure for ALS/FTD and other neurodegenerative diseases.

What Bankole loves about the Bay Area: I love living near the water and taking my dog down the bay bridge trail. When I'm not in the lab you will probably find me doing activities like sports and training martial arts or simply relaxing. I also like the diversity and culture that comes from living in San Francisco, there's a lot to explore and it's surprising how much can be packed into seven or so square miles.


Sally Salomonsson, PhD

Postdoctoral Scholar

Sally is originally from Sweden, though has lived in the UK (Scotland and England) for many years. She carried out her PhD work in the Isaacs lab at UCL, with a scholarship from the UK Medical Research Council, investigating C9orf72-associated ALS/FTD mainly in patient-derived iPSC-motor neurons. After completing her PhD in June 2022, Sally started a postdoctoral position in the Clelland lab and has chosen to work on therapies for FTD associated with genetic mutations, such as GRN.

The closely connected and collaborative scientific and clinical communities at UCSF attracted Sally, since she aspires to conduct neuroscience research with high clinical impact, and to work more closely with families affected by neurodegenerative diseases. Outside of work, she enjoys travelling, hiking and exploring, home microbiology (e.g. making sourdough bread and kombucha) and creating and experiencing art preferably together with others.
