- | I have been a postdoctoral researcher at QuIC, ULB since January 2018 working on quantum algorithms under the supervision of [[http://quic.ulb.ac.be/members/jroland|Jérémie Roland]]. Before that, I received my PhD in December 2017 from University of Lisbon, where I was affiliated to the Physics of Information and Quantum Technologies Group, supervised by Yasser Omar. During my PhD I was a visiting researcher at QuSoft, CWI Amsterdam from June 2017 - Dec 2017, hosted by Stacey Jeffery. | + | [[https://sites.google.com/view/shchakra|Shantanav Chakraborty]] is an FNRS postdoctoral researcher at [[http://quic.ulb.ac.be/|QuIC]] (October 2019-present) working on quantum algorithms with [[http://quic.ulb.ac.be/members/jroland|Jérémie Roland]].
