Philosophy of Care

Empathy is not an occupational hazard for me. The treatment of my patients' diseases may be impersonal, but the education and care of every patient I have is completely personal. Find the courage to change your health and lifestyle, and then find me to do a clinical trial of one. When you can't breathe, nothing else matters.

Clinical Interests

Dr. Louie is a pulmonologist and asthmatologist with special interests in severe asthma, the asthma-COPD overlap syndrome, and chronic obstructive pulmonary disease (COPD). 

Research/Academic Interests

Dr. Louie directs the UC Davis Asthma Network (UCAN) and the ROAD Center. ROAD (Reversible Obstructive Airway Diseases) includes COPD and the asthma-COPD overlap syndrome.
