Originally, "Dr. Michelle Lin" was envisioned only as a Grey's Anatomy guest star.

But fans of actress Lynn Chen, 44, now have a lot to look forward to: "Dr. Lin" is becoming a main character on the series. Here's what to know about the likeable actress.

"Dr. Michelle Lin" has high expectations on Grey's Anatomy

"Dr. Lin" appeared in the current Grey's Anatomy season for the first time as the new head of plastic surgery at Grey Sloan Memorial Hospital.

It quickly became clear that she has high expectations for the staff. In fact, "Dr. Lin" almost rejected the job offer because the hospital interns weren't meeting her standards.

However, training director "Richard Webber" promised "Dr. Lin" he'd get the young doctors up to speed. In the end, she agrees to take on the lead role with the hospital.
