Fellowship in Data Analyst and Machine Learning


Company Description

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact and provides insights into the fundamental laws of nature. Find out more on http://home.cern.

Diversity has been an integral part of CERN's mission since its foundation and is an established value of the organisation. See how we’re improving this further here. The international and multi-disciplinary environment makes CERN a truly unique place to work and learn.


Job Description

We are collaborating with Hoffman La Roche in the framework of CERN OpenLab to explore possible synergies in data analysis and machine learning in High Energy Physics and Epidemiology. Within this framework we are studying possible application of Reinforcement Learning to the LHCb experiment and to Epidemiology.

Concerning the LHCb experiment we are studying full data interpretation. We are developing an agent whose task will be to assign particle identifications to secondary vertices, classifying probabilities of the various decays.

Regarding Epidemiology we will focus on multimorbidity patients. Guidelines for these patients are not clear and often contradictory, especially for oncology patients affected by serious chronic illnesses. 

The successful candidate will collaborate with researchers from the department of Physics and the Institute of Epidemiology and Biostatistics of the University of Zurich.

There are 2 projects available:

  1. For 12 months, implementing Gb Generative Models to be used in an existing simulation for both Public Health and High Energy Physics data. This requires good knowledge of Generative Models such as Generative Adversarial Networks and/or Variational Autoencoders.
  2. For 24 months, a project implementing various techniques to be used in an existing simulation for both Public Health and HEP data. We require a good knowledge of Reinforcement Learning.



Eligibility criteria

  • You are a national of a CERN Member or Associate Member State;
  • You have a Bachelor or Master’s degree in Computer Science, Engineering or other related field;
  • You have no more than 4 years’ experience after completing your highest diploma.

Essential skills and experience

  • Good knowledge of Machine Learning and Deep Learning;
  • Good Knowledge of Tensorflow and/or Pytorch;
  • Passionate about data analysis and enthusiasm to work in an interdisciplinary collaboration
  • Good knowledge of Generative Models OR Reinforcement learning
