Q: If you had to give up one, would you give up your smart phone or car?
A: I would rather give up my car than my iPhone. The choice is actually easy – my iPhone is essential to me and I rely on it for a variety of needs constantly, while I can get from place to place without my car.
Q: Where are you from?
A: I am originally from Beijing, China, where I was born, grew up, and completed my college education. I came to the U.S. as an international student for graduate studies.

Q: Who are you inspired by?

She works with registry staff to provide the requested data. In addition, she has extensive experience in collaborating with interested investigators by providing expertise and staffing to conduct fieldwork for patient contact studies, and has also provided expertise on studies involving medical record review.
Q: I unwind by…
A: . . .tending to my landscaping around my house which includes a lot of cactus and succulents. I love to just look at the plants and notice minute changes—a new growth, or new bud that will flower. I attend the San Gabriel Valley Cactus and Succulent Society meetings to learn more about the plants and see slide shows from people who have traveled to see them in their native habitats (i.e. South Africa, Mexico, Peru, etc.). I have been to South Africa myself to see some of them.
Q: How do you stay active?
A: I love to go contra dancing almost every weekend. It is great form of exercise and you have to smile and that alone makes you happy. Hearing the live music and remembering the sequences in the dances helps your brain I think!

Staff In The Spotlight
I am Mexican American, married to a wonderful Chinese husband, who was born in Myanmar. We have 3 great children who we are extremely proud of. My older son is a Doctor at UC Irvine, my second daughter is a Veterinary Student Doctor, and my youngest is a senior at Pepperdine pursuing a PhD in Political Science after her undergraduate studies. I am an identical twin (seven minutes apart!) with so many funny stories I have experienced throughout my life as a twin, but that is another extraordinarily long story to tell.
I grew up helping my dad run the family business in Mexico, and we lived in El Paso, Texas before coming to LA. My mom, my sisters, and I moved to LA when I started Kindergarten for a better education. I have enjoyed traveling back and forth to Mexico, Texas and to LA during all my teen years. My father, who lived an incredibly humble life, passed away a few years ago, and I have not gone back to Mexico or Texas since.
I enjoy listening to my Spotify playlists on my daily walks or runs. I love spending time with my family. I like cooking and I love anything matcha! I love Christmas, so I enjoy cold weather, and I look forward to the winter season every year. On my free time, I travel with my husband, who is now retired. I am blessed to have traveled and experienced dream locations such as Japan, Myanmar, and Shanghai.
I have an educational background in business, various certifications, and have earned “Parent of the Year” volunteer awards. When my kids were born, I decided to spend my time just being a mom, finish college, and volunteer. I volunteered mostly at my kids’ school to be closer to them. I went to every single sport game, school party, and chaperoned their class field trips. And now, they get to spoil me!
I’ve worked at LAC-USC for a few years as an Administrative Assistant for the Department of Epidemiology and Hospital Administration office. I started as a volunteer, worked part-time as a temporary employee, and within a few months, I was offered a permanent position as a county employee. Leaving LAC-USC to come to USC was a tough decision, but fast forward to 25 years later and I’m so appreciative to still be working with CSP.
Currently, I am responsible for downloading from the secure web and uploading every transmit from hospitals in SEER*DMS. I upload new files, modified and XDL cases. I also communicate with and assist hospital registrars via secure web to ensure the efficiency of the transmit process. I oversee the CSPtrans email for incoming notifications and status updates. Additionally, I troubleshoot failed cases, run the cases using Power Automate, correct, re-upload, and submit ZD tickets when necessary. I also process the CSV files (fee for service) from hospitals for the monthly billing. This work comes with challenges; however, I’ve enjoyed my responsibilities and learn something new every day.
