Clinical & Research Interests

Dr. Björn Oskarsson's objectives are to help people with neuromuscular diseases by finding the correct diagnosis, utilizing the best medications and other interventions available today, and developing better treatment for the future.

Dr. Oskarsson directs the UC Davis ALS clinic, a multidisciplinary clinic that is a Certified Center of Excellence providing comprehensive ALS care. Dr. Oskarsson collaborates with therapists and other specialists, and connects patients with resources in the community.

Dr. Oskarsson is Board certified in Electrodiagnostic Medicine and performs EMG/NCS.  Dr. Oskarsson is also Board certified in Neuromuscular Medicine and cares for most types of neuromuscular disease including performing muscle and nerve biopsies. He is also Board certified in Clinical Neuromuscular pathology he interprets muscle and nerve biopsies.

Dr. Oskarsson’s research interests include studies developing better treatments of ALS and studies aimed at gaining a better understanding of why ALS occurs. Dr. Oskarsson works with the UCD Center for Regenerative Cures to develop stem cell treatments for ALS. He is also actively involved in clinical trials in other neuromuscular diseases.
