The ASF Scientific Advisory Committee (SAC) is responsible for overseeing research grants funded by the ASF. The ASF SAC is currently comprised of Angelman syndrome researchers and professionals from both academia and industry, clinicians who work with AS patients, and experts from related fields such as psychology, communication and education. SAC members donate their time and talent to review all research applications submitted to the ASF for funding, work with ASF staff to conduct an annual Scientific Symposium, and work with the ASF on research collaboration.
The ASF and the ASF SAC play a strong role in networking researchers and funding research that pursues promising avenues of discovery. ASF SAC membership is evaluated and renewed on two-year terms, ensuring that a range of voices and opinions are expressed during the research funding process.
