My Journey in Medicine

I chose sleep medicine because sleep affects all aspects of a person’s life, from their physical and mental health to their relationships and well-being. I felt sleep medicine was the best way for me to affect my patients’ lives.

Soon after completing my medical training, I began teaching future doctors, first at UCSF and then Yale for the past decade. I enjoy switching between instructing, helping patients with sleep conditions, and conducting research. 

My areas of clinical and research interest include complex sleep-related breathing disorders and sex differences in sleep-disordered breathing and hypersomnias. I’ve found in my research that females experience sleep and sleep deprivation in diverse ways compared to males. Changes that we go through—such as menstruation, pregnancy, and menopause—all have a big impact on sleep, and I find it a fascinating subject. I love being able to add to the body of knowledge about women’s health as it relates to sleep.

When I see patients, I listen to each person to understand their unique circumstances and needs so I can develop a comprehensive treatment plan. Treating sleep disorders can be a complex process that requires specialized care and attention; it’s really not just about taking a pill! So, I always take time to explain the different treatment options so that patients can make informed decisions about their care. 

At Flo, I advise on health content related to sleep, and I’m grateful to spread scientific knowledge that helps millions of users worldwide sleep better and live overall healthier lives.
