Casting a Male and Female lead for non-speaking Scientist roles in online promotional video

A short online commercial to help inspire/remind researchers why they got into science–their dream was to cure disease, to help people, and through partnerships we can help them achieve this. This commercial follows a male and female scientist through a typical day of their lives working in science, whose teams come together at the end to achieve what they couldn’t do alone. They are both non-speaking roles (as a voice over will be recorded afterwards).
The male lead [30-45 years old] is the principal investigator of his research lab, he has a family, and is also active. He will be featured working in a lab, cooking with his family, running along the sea wall, and collaborating with other research groups. The female lead [28-43 years old] is a scientist, will be shown working in a lab, reading journals in a coffee shop, and practicing yoga.
