DESCRIPTION:I will present an overview of recent developments in source de
 tection and estimation in randomly growing graphs and diffusions on graphs
 . Can one detect the influence of the initial seed graph? How good are roo
 t-finding algorithms? Can one engineer messaging protocols that hide the s
 ource of a rumor? I will explore such questions in the talk. This is based
  on joint works with Sebastien Bubeck\, Ronen Eldan\, Elchanan Mossel\, Ja
 cob Richey\, and Tselil Schramm.&nbsp\;
