AI method named one of 2019¿s most exciting discoveries in optics research

News: Dec 12, 2019

Optics & Photonics News has picked Saga Helgadottir’s work on deep learning for particle tracking as a top break-through of the year.
“This has been a really good year for me, research-wise. My publication, presenting a new AI method, garnered a lot of attention,” says Saga Helgadottir, PhD student at the Department of Physics.

The research article in question, which is now gracing Optics & Photonics News’ best-of-2019 list, identifies a new way of implementing neural networks and machine learning in order to track particle motion and study surrounding microenvironments.

After the publication in mid-April, Saga Helgadottir was contacted by both national and international press to talk about her discoveries. She has also been invited to visit research groups abroad and was a speaker at the AI in Health and Health in AI conference held in Gothenburg in November.

Currently, Saga Helgadottir is collaborating with a group of scientists at the Wallenberg laboratory. They’re working on new ways of using deep learning in the medical field.

“I started my PhD research studying bio-hybrid micro swimmers, but ended up more within the area of artificial intelligence and optics. I like this work a lot, and the positive response to my publication earlier this year has allowed me to establish myself in the AI-field.”

Original press release about the research:



  • Uppfinningen som gör optiska pincetter tillgängliga för alla

    [16 Dec 2019] A device that could be installed on any microscope and would simplify the use of optical tweezers to study single cells is being developed by scientists at the Department of Physics. After receiving early acclaim for the idea from Venture Cup, the group hopes to launch their company in 2020.

  • Thomas Blackburn acclaimed for research on high-intensity lasers

    [6 Dec 2019] Researcher Thomas Blackburn has received an Early Career Award from the New Journal of Physics. His work on modelling high-intensity lasers is being highlighted as a significant contribution to the field.

  • New laser physics achieves energy at astronomical levels

    [1 Jul 2019] With the help of extremely strong light pulses, photons with huge amounts of energy can be released. This paves the way for brand new types of experiments. A group of physicists from the University of Gothenburg and Chalmers have simulated laser configurations that could bring space phenomena into the lab.
