1. Lineages, Biological Classification, and Evolution - The concept of “lineages” is taken for granted in many biological and philosophical discussions, but a closer look suggests that it has different meanings, scientific roles, and ontological assumptions depending on the context. These differences have significant ramifications for biology and philosophy, such as the idea that there are multiple kinds of lineages in the natural world. I explore this and other ideas in my dissertation and related papers (see below). Currently, I also investigate how borderline and complex cases of evolution by natural selection change our understanding of lineages, persistence, and other key concepts in biological classification and evolution.    
2. Race, Human Classification, and Values Are races real? I investigate how social values influence the answer of philosophers, scientists, and citizens to this question. For instance, recent defenses of biological racial realism are pluralistic (Hardimon 2017, Spencer 2019). Racial realism is pluralistic because it accepts that more than one concept of race is legitimate. How can we distinguish legitimate from illegitimate concepts of race? I consider whether and how social values play a role in answering this question. I am currently finishing my first manuscript about this issue (see below). In the future, one of my goals is to develop a comparative analysis of race concepts in Brazil and North America, exploring their intersections with migration issues.
