Research

Dr. Johnson's research interests include the control of breathing in neurological diseases such as mutliple sclerosis and how the body compensates (or cannot compensate) for such disease states (i.e. neuroplasticity).

Clinical Interests

Dr. Johnson's clinical interests include anesthesia and its effects on respiratory physiology as well as the continuing clinical education of veterinary technicians and practicing veterinarians.
