Seminar in hybrid format in GERAD room 4488 or Zoom.

Conversations over a cup of coffee can go beyond one's expertise. Often, they provide a comfortable environment to discuss problems and question ideas. Thus, in this coffee talks seminar, I will take their naming literally and provide different ideas encouraging the discussion about the need to develop responsible decision support tools. Otherwise, those tools may create inequalities and hurt social welfare. To achieve my goal, I will describe a series of examples where the human connection of decisions will be emphasized. These examples will range from sustainability to education. Then, I will focus on a particular example in the health field, related to kidney exchange programs, and show how decomposition methods can be used to efficiently implement fairness based on theories of justice.
