**Engineering Social Networks**Nicole Immorlica, Northwestern University**networks:**exogenous, endogenous, … or designed?**example:**designing networks to engineer diversity.**initially,**a regular directed graph blue and yellow nodes**at time t,**link to mR nodes at random 1. 2. link to mS nodes via color- biased searching**parameters:**q, fraction of blue to yellow mR, # of random neighbors mS, # of biased neighbors**question:**what is the diversity as a function of q, mR, and mS?**argo tea observations:**(joint with B. Lucier and B. Rogers) steady-state diversity is independent of mS 1. 2. speed of convergence is function of mR/mS**lesson:**a centralized designer can enforce diversity by insisting that people have a few random friends.**killer app #1:**Schelling model of segregation**question:**(joint with Kleinberg2 and Sinclair) can we decrease segregation by teaching tolerance? who should we target?**killer app #2, 3, 4, …:**(half-baked) poverty traps information cascades fostering collaboration
