I will leave you with what I think is a great quote by Aurora Clark, a chemistry professor with Washington State University.
“One of the beautiful things about conferences is that they provide a platform for showcasing a large group of people working on a problem. If you omit an entire population, then you not only hurt those you omit, but also yourself and your own opportunities to learn and develop a research program, not to mention recruiting new talent to our programs. What if the next Einstein is an undergrad working in your group and she decides she wants to go into Biology because she doesn’t see anyone that respects her ideas or believes in her potential?”
(And yes, I think there is a small diss on Biology here because it is one of a few scientific fields that has about equal (or more) females compared to males.)
