Hobbies: I love watching movies and playing video games. I am a TECH fanatic. When not scoping or seeing patients, I spent time building a top-end gaming rig, my own home theater and streaming service, a Network Attached Storage (NAS), and a smart home system. 

Favorite things to do in Rochester: Even though I grew up in a metropolis in China with a population of 6 million, I was pleasantly surprised by the diversity of Rochester. Mayo Clinic is a vibrant presence that brings in people from all over the world while maintaining the intimacy of communities. Summer is most gorgeous, but we do outdoor activities all year long. Every weekend there are numerous free activities organized by community individuals and groups. We love taking our kids to hike, bike, and camp, and really enjoy the Olmstead County Fair. Authentic Asian food/ingredients can be accessed through "secret" community markets and I'd be happy to introduce you to the group!

Why Mayo: I chose Mayo for its outstanding clinical training and unparalleled research opportunities. At this world-class referral center, fellows learn alongside legendary clinicians and research pioneers to care for the most complex cases. Intra- and inter-disciplinary care takes place on a regular basis to enrich learning. There is a perfect balance between clinical workload and protected learning time. Mayo is at the forefront of clinical and translational research. Just go to DDW or ACG to appreciate Mayo's deep roots in the soil of gastroenterology. All fellows get 12 months of protected research time and collectively we are a very productive bunch!

Future plans: I will be continuing at Mayo Clinic for advanced training in esophageal diseases.

Many of the Mayo Clinic values mirror my training in medical school at the Royal College of Surgeons in Ireland.

Hobbies: Playing drums, collecting records, going to concerts/festivals, and supporting local (micro) breweries

Favorite things to do in Rochester: Attending the (surprisingly numerous) music events at different venues (usually breweries and DIY-venues)

I had no intention to pursue training in the United States then, but the superb quality of the clinical teaching pushed me to obtain my USMLE's and apply to Mayo Clinic for residency. Fast-forward three years and my choice for fellowship was very easy thanks to the incredible organization of Mayo as an institution, the approachability of the 80+ GI faculty, and the culture that strongly emphasizes patient care above all.

Future plans: I have a profound interest in pancreatic diseases, both benign and malignant. I want to pursue a career in academic medicine that combines advanced pancreatic procedures (ERCP, EUS) with medical pancreatology.

Why Mayo: Mayo Clinic truly embodies the three shields (patient care, education, and research) remarkably well. Not only do you have exposure to bread-and-butter gastroenterology and hepatology cases, but you are able to see (and manage!) complex patient cases throughout your time as a fellow. The collegiality and camaraderie amongst fellows, faculty, and staff is second to none. Everyone truly places the needs of the patient first. Endless research and educational opportunities, as well as support, abound at Mayo Clinic so that you may find your area of interest as you begin your career as a gastroenterologist and/or hepatologist!

Future plans: I'm still somewhat undecided. I am contemplating an advanced IBD year and pursuing a career in academic medicine versus practicing gastroenterology in a community-based setting.

Favorite things to do in Rochester: I'm still new to the area, so I'm looking at what's around and it seems like there are a ton of natural parks and hikes here! 

Why Mayo: I found a place that had the mentors I wanted (for research and clinical practice) at Mayo. I connected with them during my interview and on subsequent meetings. Mayo is the best place for me to grow into becoming the best physician-scientist I can be, and it comes with a host of opportunities to nurture that growth.
