Early life and education

Williams was born in Australia and moved to the United States in 1978[2].

Williams graduated from the University of Melbourne with a Bachelor of Sciences, with honors, and a Master of Science in Mathematics[3]. Williams went on to earn her Ph.D. from Stanford University in 1983, under the supervision of Chung Kai-lai.[4][5]

Recognition

Williams was president of the Institute of Mathematical Statistics from 2011–2012.

Williams is a member of the National Academy of Sciences and a fellow of the American Academy of Arts and Sciences, the American Association for the Advancement of Science, the American Mathematical Society, the Institute of Mathematical Statistics, the Institute for Operations Research and the Management Sciences,[6] and the Society for Industrial and Applied Mathematics.[7] In 1998 she was an Invited Speaker of the International Congress of Mathematicians in Berlin.[8]

Her other awards and honors include:

  • Alfred P. Sloan Fellow (1988) [9]
  • Guggenheim Fellow (2001)[10]
  • Best Publication Award of the INFORMS Applied Probability Society (2007), jointly with Amber Puha and H. Christian Gromoll[11]
  • John von Neumann Theory Prize (2016), jointly with Martin I. Reiman for "seminal research contributions over the past several decades, to the theory and applications of stochastic networks/systems and their heavy traffic approximations".[11][12]
  • Honorary Doctorate from the University of Melborne (2018) [2]
  • Award for the Advancement of Women in Operations Research and the Management Sciences (2017), annual INFORMS meeting[11]
  • Honorary Doctor of Science degree from La Trobe University in Australia[11]
  • National Science Foundation Presidential Young Investigator[11]
gollark: Well, I wouldn't trust a computer which had (has?) ransomware on it which has not gone through a reinstall.
gollark: Most modern x86 computers, that is.
gollark: I think most stuff boots using UEFI now. Though it's probably the same concept.
gollark: Hmm, so possibly not then. you should definitely reinstall though.
gollark: If it's a ransomware thingy, it is possible that you have already lost some of your files to it.
