DESCRIPTION:By: Natacha Crooks - University of Texas at Austin\nIC Faculty
  candidate\n\nAbstract:\nCloud storage offers these applications simplicit
 y: the abstraction of a failure-free\, perfectly scalable black-box.  Whi
 le appealing\, offloading data to the cloud is not without challenges. Clo
 ud storage systems often favour weaker levels of isolation and consistency
 . These weaker guarantees introduce behaviours that\, without care\, can b
 reak application logic. Offloading data to an untrusted third party like t
 he cloud also raises questions of security and privacy.\n\nThis talk summa
 rises my efforts to improve the performance\, the semantics and the securi
 ty of transactional cloud storage systems. It centers around a simple idea
 : defining consistency guarantees from the perspective of the applications
  that observe these guarantees\, rather than from the perspective of the s
 ystems that implement them. I will discuss how this new perspective brings
  forth several benefits. First\, it offers simpler and cleaner definitions
  of weak isolation and consistency guarantees. Second\, it enables more sc
 alable implementations of existing guarantees like causal consistency. Fin
 ally\,  I will discuss its applications to security: our client-centric p
 erspective allows us to add obliviousness guarantees to transactional clou
 d storage systems.\n\nBio:\nNatacha Crooks is a PhD candidate at the Unive
 rsity of Texas at Austin and a visiting student at Cornell University. Her
  research interests are in distributed systems\, distributed computing and
  databases. She is the recipient of a Google Doctoral Fellowship in Distri
 buted Computing and a Microsoft Research Women Fellowship.\n\nMore informa
