"As a pulmonologist, my mission is to help patients in our community breathe better and be able to enjoy a good quality of life. I joined UCLA Health because I can provide my patients the highest level of care by blending the academic research knowledge of UCLA with evidence-based medicine."

Dr Merchant worked as a private practice hospitalist in Southern California for three years after completing her residency in Internal Medicine at UCSF-Fresno in 2007. She then pursued a fellowship in Pulmonary/Critical Care Medicine at Cedars-Sinai Medical Center.

She is currently a Clinical Instructor of Medicine at David Geffen - UCLA School of Medicine.
