Sonia Rios-Ventura
Family Health Navigator, Medicine - Med/Oncology
BioSonia Rios-Ventura is a clinical research coordinator associate for the Stanford School of Medicine, department of Cancer Genetics and Genomics. She received her B.A. in anthropology and intensive sociology from the University of California Santa Cruz.
She is also the family health navigator for the Genetic Information and Family Testing (GIFT) Study. GIFT's mission is to help families beat cancer. It aims to save lives through education and communication about cancer risk and prevention in families. When someone learns they have a genetic mutation that increases their risk for cancer, it means their family members might also be at risk. For too long, the difficult job of talking about family cancer risk has fallen to the cancer patients alone. GIFT is here to make it easier for people to share this important information and give family members an easy way to get genetic testing to learn about their personal cancer risk. GIFT is an online program developed by cancer patients, family members, and doctors that offers a new way to, 1. Share life-saving information about family cancer risk and ways to lower that risk, 2.Connect interested family members to easy, at-home genetic testing. -

Juan Rivas-Davila
Associate Professor of Electrical Engineering and Senior Fellow at the Precourt Institute for Energy
Current Research and Scholarly InterestsModern applications demand power capabilities beyond what is presently achievable. High performance systems need high power density and bandwidth that are difficult to achieve.
Power density can be improved with better semiconductors and passive componets, and by reducing the energy storage requirements of the system. By dramatically increasing switching frequency it is possible to reduce size of power converters. I'm interested in high performance/frequency circuits switching >10 MHz. -
