When will the next course be held?

We typically run our PARAFAC course bianually in person. However, under the current conditions, we may hold online courses more freqently. Please monitor this space and our ResearchGate projects for updates.

About this course

We regularly offer a course called “Parallel Factor Analysis for DOM fluorescence”. In the last edition (Octbober 2020) it was an online course run by Kathleen Murphy (Chalmers University of Technology), Urban Wünsch (Technical University of Denmark), and Colin Stedmon (Technical University of Denmark).

In our course, you will learn how to analyze the fluorescence composition of dissloved organic matter using PARAFAC.

This course provides instruction on best-practice application of PARAFAC to fluorescence datasets, demonstrated using the drEEM toolbox for MATLAB.

The course is currently mainly delivered online using written documents, recorded lectures and videos. Participants are expected to upload an assignment during each week of the course. You can bring your own data or use the datasets provided. The expected workload is 10-30 hours per week depending on prior experience. All participants need to have access to MATLAB (2018 or later) and the ability to install the drEEM toolbox for MATLAB (admin rights not required).

The course is part of a long-term collaboration between researchers at Chalmers University of Technology and the Technical University of Denmark.

After completing the course, the student should be able to independently produce a validated PARAFAC model from fluorescence and absorbance measurements using the drEEM toolbox in MATLAB.

Students demonstrate their progress in the course by uploading assignments. A certificate recommending the award of 5 ECTS (Higher Education Credits) will be sent to participants that complete all three assignments.

Specific learning goals

  • Describe the theory of PARAFAC for fluorescence and its underlying assumptions
  • Describe why inner filter effects occur and how to deal with them
  • Clean a fluorescence dataset (identify and eliminate bad data)
  • Model a fluorescence EEM dataset
  • Validate the model using internal and external methods
  • Interpret a PARAFAC model of FDOM

What will be covered? What will we discuss?

  • Content covered in videos/lectures
  • Content covered in papers where instructors were co-authors
  • Using the drEEM toolbox
  • Cleaning and modelling EEM datasets.
  • Validating and exporting PARAFAC models
  • Interpreting PARAFAC models of DOM fluorescence.

What we will not cover

The list of topics that users want to discuss is very long. Unforntunately we cannot cover everything. From previous experiences, we have to refrain from the following topics in the interest of time:

  • Using and calibrating your fluorometer
  • Measuring and applying spectral correction factors
  • EEM calibration, i.e. conversion to RU or QSE units
  • Implementing PARAFAC using different software platforms: e.g. PLS_Toolbox, staRdom, DOMFluor.

Private consultations can be booked to discuss topics within the scope of the course.
