A Nonprofit ALS Research Institute
We were founded by a family with ALS, and our research is funded by the ALS community.
About Us About Us
A Nonprofit ALS Research Institute
We were founded by a family with ALS, and our research is funded by the ALS community.
Founded by a Family
Stephen Heywood was diagnosed with ALS at age 29. After finding no treatment options, his brother, Jamie Heywood, realized that a gap existed in the preclinical development of therapies for ALS.
In 1999, Jamie founded the ALS Therapy Development Foundation, now the ALS Therapy Development Institute (ALS TDI), in the basement of his family's Newton, MA home in an effort to bridge this gap and bring effective treatments to people with ALS as quickly as possible.

Though my father did not live to see it, he truly believed that by uniting the community, and working together to fund research, we could find a cure for ALS. Today, his legacy is alive in the ALS Therapy Development Institute and their relentless work to end ALS.”
— Alex Heywood, son of Stephen Heywood, ALS TDI co-founder
Fueled by Our Community
We are the Drug Discovery Engine for ALS. The ALS Therapy Development Institute (ALS TDI) is the largest drug discovery institute in the world focused solely on finding treatments for ALS.
As a 501(c)3 nonprofit biotech, we answer only to the ALS community. ALS TDI is funded by people with ALS and their friends and families – because they believe that our scientists will discover the treatments needed to end it.
We are united in one shared mission – to ensure that everyone with ALS has access to effective treatments.
Tony did a lot of research, when he was able to, about who to donate to and who to partner with, and he felt strongly that because of Jamie Heywood and his situation with his brother, they were also as motivated as he was.”
— Walter Tucker, brother of Tony Tucker who lived with ALS for 18 years

Milestones Over the Years
  • 2023
    2023
    Global Collaboration
    In March 2023, ALS TDI officially launched the ALS Research Collaborative (ARC) – an ambitious global initiative developed to better understand the underlying biology of the disease, and significantly accelerate the discovery of ALS treatments.
    ARC collects natural history data from people with ALS and layers this with additional data that measures their underlying biological processes through omics. This extensive collection of data – that patient participants continue to add to – is made accessible to researchers worldwide through the ARC Data Commons, an innovative data-sharing platform powered by Google Cloud and Google's Looker application.
