About the position 

The postdoctoral fellowship position is a temporary position where the main goal is to qualify for work in senior academic positions.  

Ugelstad Laboratory ( at Department of Chemical Engineering ( has a vacant Post.Doc. position within development of Computer Vision methods for real-time detection and classification of microfluidic generated droplets, bubbles and solids.

Ugelstad Laboratory covers a range of fundamental and applied research within surface, colloid and polymer chemistry. The group is active within topics such as characterisation of complex fluids and interfaces, surfactants and biopolymers, particle synthesis, gas flotation and multiphase flow in porous media. In recent years microfluidic platforms have been used to prepare and characterise dispersed systems, and image-based analyses have provided information about coalescence in emulsions (, drop-bubble attachments (10.1021/acs.energyfuels.8b02236), transport of emulsions in porous media ( and synthesis of nanoparticles (

In parallel, deep neural networks have been shown to be even more effective at feature extraction than widely used tools within Matlab/Python libraries and ImageJ for the detection and classification of droplets (

The Project

We are now looking for a Post.doc. fellow that can continue to develop the synergies between machine-/deep learning methods and high-throughput imaging on microfluidic platforms. The goal is to develop real-time computer vision tools for detection, classification and tracking of drops, bubbles and solids.

The candidate will work in close collaboration with other researchers in the group that will carry out experimental microfluidic work related to i) controlling interfacial properties to optimise drop/bubble stability/separation, ii) controlling synthetic conditions to optimise nanoparticle properties, and iii) following transport and retention of drops and particles flowing in porous media. Hence, we primarily want a post.doc candidate with strong programming skills and good understanding of experimental work that can collaborate with one or more of these researchers and utilise their data for the development of analytical tools. 

You will report to Professor Gisle Øye.

The latest startup of the project should be 01.08.2023 due to collaboration with other research projects in the group.

Duties of the position

  • Develop real-time computer vision tools for detection, classification and characterization of drops, bubbles and solids.
  • Present project results at project meetings, workshops, and conferences.
  • Train MSc and PhD students to use the developed tools.
  • Assist MSc and PhD students with developing optical tools for characterizing transport and deformation of suspended droplets and solids.
  • Prepare user-friendly manuals for the developed tools.
  • Prepare scientific papers.
  • Contribute to preparation of grant proposals.

Required selection criteria

  • PhD within computer vision methods or related topics
  • Strong programming skills with working knowledge and documented experience with Python/Matlab
  • Good written and oral English language skills
  • You must meet the requirements for admission to the faculty's doctoral program Chemical Engineering (

The appointment is to be made in accordance with Regulations on terms of employment for positions such as postdoctoral fellow, Ph.D Candidate, research assistant and specialist candidate.

Preferred selection criteria

  • Experience in PyTorch/TensorFlow.
  • Good knowledge of chemical engineering, surface and colloid chemistry or microfluidic methods (including device design).
  • Experience with developing theoretical models for rationalization.
  • Experience with scientific writing.
  • Good written and oral Norwegian language skills.

Personal characteristics

  • Self-motivated, pro-active and goal oriented.
  • Good communication skills with both experimentalists and theorists.
  • Good collaborative skills with both experimentalists and theorists.
  • Organized and patient with problem-solving mindset.

Emphasis will be placed on personal and interpersonal qualities.
