Putting resources and knowledge in the hands of pediatric cancer experts poised for the next big discovery.

Our Mission

Our mission is to empower pediatric cancer experts poised for the next big discovery with the knowledge, data, and tools to reach it.

We construct tools that make vast amounts of data widely available, easily mineable, and broadly reusable.

We train researchers and scientists to better understand their own data and to advance their work more quickly.

The Data Lab upholds the values of creating kind and supportive environments for childhood cancer research and democratizing access to tools and data in all settings.

Our Story

The Childhood Cancer Data Lab was established by Alex’s Lemonade Stand Foundation (ALSF) in 2017. ALSF recognized that pediatric cancer researchers face hurdles that impede the pace of research. A massive amount of childhood cancer data exists, but collecting, sharing, and utilizing it can be a challenge. Far too often, data is not available in a ready-to-use format or found in easily accessible locations, making it difficult for researchers to carry out analyses and answer their scientific questions. ALSF introduced the Data Lab to empower researchers and scientists across the globe by removing roadblocks, supporting opportunities for collaboration and sharing, and developing resources to accelerate new treatment and cure discovery.

More about Alex’s Lemonade Stand Foundation

Alex's Lemonade Stand Foundation Logo

Alex's Lemonade Stand Foundation (ALSF) emerged from the front yard lemonade stand of 4-year-old Alexandra “Alex” Scott, who was fighting cancer and wanted to raise money to find cures for all children with cancer. Her spirit and determination inspired others to support her cause, and when she passed away at the age of 8, she had raised $1 million. Since then, the foundation bearing her name has evolved into a national fundraising movement. Today, ALSF is one of the leading funders of pediatric cancer research in the U.S. and Canada raising more than $200 million so far, funding nearly 1,000 research projects, and providing programs to families affected by childhood cancer.
