Sandra is the founder of Genentech Women in Science and Engineering (gWISE), whose mission is to help Genentech become the leader in advancing the role of women in biotech. Sandra recruits women of colour to attend and participate in gWISE-sponsored events and developed strategies to find, retain and address the needs of women, and in particular women of colour, in scientific roles at Genentech. gWISE sponsored unconscious bias training for executives, and she has developed policies designed to encourage those leaders to think more about creating a level playing field for recruiting and hiring women, and in particular women of colour. Sandra is a Genentech Diversity and Inclusion Ambassador, regularly serving as a panellist, and mentors for the Genentech Leader-Intern Exchange (gLINX) Programme. She also serves as a Keynote Speaker for internal organizations such as the South East Asian Club. She has also spoken at organisations such as the Society for Chicanos and Native Americans in Science and at National Latino Cancer Summit. She frequently serves as a panellist for many different minority-focused organisations at leading universities, such as UC Berkeley and SFSU helping place many students in laboratories and industry internships.
