    Biography

    I am a medical oncologist specializing in the treatment of patients with non-small cell lung cancer. My research focuses on strategies for improved understanding and treatment of lung cancer. I have several specific areas of research focus, which include:

    • Acquired resistance to targeted therapies (EGFR, ALK, etc) in lung cancer
    • Targeted therapies and clinical trial design for rare lung cancer genotypes
    • The biology of lung cancer diagnosed at a young age (under the age of 50)
    • Familial lung cancer in non-smokers
    • Noninvasive lung cancer genotyping through analysis of free floating DNA in the blood
