Dr. Nixon is board certified in anatomic, clinical, and neuropathology—specializing in diseases of the central nervous system and muscles. His advanced training includes a fellowship in Neuropathology at UCSF, including extensive training in diseases of the central nervous system (CNS) such as tumors, inflammatory diseases, infectious diseases, and neurodegenerative diseases (i.e. dementias and movement disorders), as well as in diseases of skeletal muscles such as muscular dystrophies, inflammatory diseases, and metabolic diseases.

Dr. Nixon holds a PhD in Biochemistry, and has performed research on Creutzfeldt-Jakob disease with Drs.

His research in Biochemistry resulted in the development of new clinical tests that lead to the identification of previously unknown inherited coagulation diseases.
