Cancer Surveillance Team

Lihua Liu

Principal Investigator, Director

As Director, Dr. Liu is responsible for leading CSP to fulfill its legally mandated obligation to collect cancer diagnoses and monitor cancer risk patterns and trends among the diverse populations of Los Angeles County.

1. If you had to give up one, would you give up your smart phone or car?

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.

2. Where are you from?

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.

Andrea Sipin​-Baliwas

Director of Registry Operations, Program Manager

As Director of Registry Operations, Andrea oversees the operational units of CSP to ensure high quality, complete, and timely collection and processing of cancer data from hospital and non-hospital reporting sources in Los Angeles County. She oversees electronic pathology reporting activities, rapid case ascertainment for long-term research studies, and contributes to other efforts that support near-real-time data collection and utilization. Andrea serves in leadership roles at the state and national level and is an advocate for professional development and strengthened communications across the cancer surveillance community.

Who are you inspired by?

My late grandmother, Constancia, inspires me to not be afraid to think unconventionally and always serve others. She started and sustained a Manila-based transportation company in a male-dominated field and served on committees in the public sector, all while raising a large family.

 I unwind by…

Listening to my “Sunday Afternoon” playlist on Spotify while cooking (Happy to share it, let me know!)

My dad, for his resilience, gentleness and diligence.

2.  If you had to give up one, would you give up your smart phone or car?

My children

She counsels them on the availability and appropriateness of registry data for their needs, and assures that necessary approvals (including Institutional Review Board human subject approvals as well as  administrative approvals) are obtained. 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.

1. I unwind by…

. . .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.

2. How do you stay active?

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!

Dianne M. Kerford

IT Manager

As MIS Manager, Dianne manages Information technology and programming projects at the CSP. Dianne oversees technical support, confidentiality and security compliance, project management of hardware and software upgrades, programming support for various cancer research studies and data submissions to national programs.

1.  At what battery percentage do you plug in your phone?

During the week I don’t let my phone go below 50% but on the weekend it usually dies on me. 

2. Favorite song at the moment?

I’m all over the place as far as music goes but my all-time favorite is Sweet Emotion by Aerosmith.  Memories of my first concert.
