The MCB Department is fully committed to supporting, in every way possible, all members of our department, irrespective of their national origin, religious background, race, color, age, sex, gender, gender identity, or sexual orientation. We are particularly troubled by the recent Executive Order on Immigration because it threatens members of our community and the practice of science. MCB scientists and staff come from many countries and engage in numerous international collaborations. Our research is enhanced by the diversity of perspectives provided by scientists from different backgrounds including international scientists. In addition, everyone’s science benefits when all scientists can travel freely between the U.S. and other countries to communicate directly with each other. We will resist policies that threaten our scientific culture and values.
