Personal Interests: While most of my time lately is spent obsessing over my young son, I do have a lot of interests outside of him! I love traveling and exploring new cities and countries - my favorite destination thus far has been Thailand. My husband and I love food, and we enjoy trying new restaurants in Nashville. My favorite way to decompress is by working out - I love going for walks around the neighborhood with my dog, taking classes on my Peloton, and doing Pilates. Last but certainly not least, I love watching the latest reality TV shows on Netflix.

Why I Chose Vanderbilt: This fellowship program is the perfect balance of excellent clinical experience and robust academic and research training. The previous fellowship graduates have been productive during their training and have moved on to become well respected leaders in the PHM world. The division is home to wonderful clinicians and researchers that are deeply involved in the fellowship program. During my interview, I could immediately tell that the people in this group are not only intelligent, but also kind, invested, and welcoming.

It is a huge perk that the program is in Nashville, which is such a unique and lively city. I am so excited to get to know both Vanderbilt and Nashville during my time here.

Phoenix, originally from China, completed a combined medical program before pursuing a career in genetics. Inspired by a case involving Duchenne Muscular Dystrophy during her tenure as a Rheumatologist, she transitioned to genetic counseling under the guidance of her mentor from medical school. After obtaining further education in the United States, Phoenix dedicated a decade to serving as a prenatal genetic counselor. Known for her warm-hearted nature and passion for helping others, Phoenix has actively volunteered, providing support to parents at Children's Hospital, caring for ill children at Cavett Camp, and teaching at her local church.

Outside of medicine, Phoenix treasures time with her family and friends, especially her daughter. She enjoys gaming—particularly League of Legends—swimming, cooking, and exploring diverse cuisines.
