Computer Laboratory

Diana Andreea Popescu


I am a PhD student in Computer Science and a Marie Curie Early-Stage Researcher in the Networking and Operating Systems Group at the University of Cambridge, Computer Laboratory, and my advisor is Dr. Andrew Moore. I am currently working on assessing the impact of network latency on typical cloud applications' performance. I am interested in data centre networking, network measurement, SDN and programmable data planes. My work is funded by the Marie Curie ITN project METRICS.

I did my undergraduate degree in Computer Science at the University Politehnica of Bucharest, Romania, and my master degree in Computer Science at École Polytechnique Fédérale de Lausanne, Switzerland. I interned at Google twice, in Zurich in 2013 and in Mountain View in 2015, and at CERN in 2013, where I completed my master thesis.

I am a member of Churchill College. I serve as postgraduate representative and media chair on the women@CL committee. I was awarded a Women Techmakers Scholarship by Google in 2017.

Work Experience

  • Software Engineering Intern at Google, Mountain View, USA, June 2015 - September 2015
    I worked in the Platforms Networking team on improving a network monitoring system used in Google's data centers.
  • Site Reliability Engineer Intern at Google, Zurich, Switzerland, August 2013 - January 2014
    I worked in the Social Storage SRE team on measuring the CPU usage of individual user queries in order to estimate the cost of a query.
  • Master Thesis Intern at CERN, Geneva, Switzerland, February 2013 - July 2013
    Research on parallelisation techniques for the library used in the design of the Final Focus System of the future accelerators, International Linear Collider (ILC) and the Compact Linear Collider (CLIC).
  • Intern at CERN openlab, Geneva, Switzerland, July 2010 - August 2010
    Performance monitoring of the software frameworks for the Large Hadron Collider experiments.
