My teaching is not gender biased, is it?

Gender bias and underrepresentation in society are likewise pervasive in Science, Technology, Engineering, and Math fields and are difficult to balance out. In Aquatic Sciences, large efforts have been made to increase awareness on Diversity, Equity, Inclusion, and Justice and yet, gender- and diversity-gaps remain. Reducing these gaps requires work in different dimensions: individual, community, education, and society. As scientists, we can act at all those levels in various ways and one effective approach is through education. When teaching and supervising students we can be role models, actively, consciously, and explicitly including diverse and historically underrepresented scientists in our teaching material or creating an inclusive class environment. But, where to start?
