We would like to bring to your attention the opening of 2 Early-Stage Researcher (PhD) positions in the Centre for Research in String Theory at Queen Mary, University of London. These are part of the Innovative Training Network of the European Commission SAGEX, or "Scattering Amplitudes: from Geometry to Experiment". Please consult the SAGEX website https://sagex.ph.qmul.ac.uk for more details of the network overall, while detailed descriptions of these positions (ESR1 and ESR2) can be found at https://sagex.ph.qmul.ac.uk/?page_id=4. Applications must be made through the official link https://webapps2.is.qmul.ac.uk/jobs/job.action?jobID=3297, which also contains crucial details about eligibility requirements, salaries and other aspects of the positions. The preferred start date for both posts is 1st October 2018, and in any case no later than 1st May 2019. The deadline for applications is May 29, 2018. Informal enquiries should be addressed to Professors Andreas Brandhuber and Gabriele Travaglini, who will supervise these positions, at a.brandhuber@qmul.ac.uk and at g.travaglini@qmul.ac.uk. General information about the School can be found at www.ph.qmul.ac.uk and about the Centre for Research in String Theory at www.strings.ph.qmul.ac.uk. The School currently has six academics working in the area of scattering amplitudes: Andreas Brandhuber, Ricardo Monteiro, Bill Spence, Gabriele Travaglini, Congkao Wen and Chris White. Technical questions regarding the application procedure must be directed to Ms Jazmina Vaca Ortiz on j.vaca-ortiz@qmul.ac.uk Two reference letters should also be sent to the same email address, to arrive by the deadline. Given the timing of the current PhD hiring cycle, we would be extremely grateful if you could pass this on to any student you think might be interested.
