Introduction to Practical Experiment Geochemistry (iPEG)

Welcome to the iPEG webpages. iPEG is a three day course introducing the fundamentals of practical inorganic geochemistry. This training course aims to take 1st year PhD and Masters students through the fundamentals of experimental inorganic geochemistry. We will guide students from sample collection to analysis; with sessions covering field work (optional), basic laboratory skills, analytical techniques, data analysis, and data interpretation.

iPEG is based in the Cohen Laboratories within the School of Earth and Environment (University of Leeds). The Cohen labs are a world leading centre for geochemistry. iPEG course was born from a need to train our own PhD students in these skills. We are now opening it up to any PhD or Masters students with an inorganic geochemical focus.

The course runs over 3 days (15, 16, 17th November 2017) and is limited to 14 participants. As an introductory offer, the course will cost £200 per person. This includes tea, coffee, lunch, etc. but not accommodation or breakfast/evening meals.

  • 17, 18, 19th January 2018
  • Cost: £200-300 (TBC)

If you would like any further information please contact Andy Connelly. You can also follow us on Twitter (@CohenGeochem) where we will be giving regular updates.

We will put more information up here over the next few weeks. For now, please see below for an idea of the types of seminars and laboratory session we will be running.
