About me

Postdoctoral researcher within the area of ergonomics at the Unit of Occupational medicine, IMM, Karolinska Institutet.

Research description

Ergonomics and prevention of work-related musculoskeletal disorders (WMSDs) have been my research interest since my PhD time. With the UN Sustainable Development goals on Good health and well-being, and Decent work and economic growth, ergonomics is playing an increasingly important role to achieve a sustainable working life.

My research projects involved the development and evaluation of technical methods in ergonomics, which can be convenient to use and of lower cost compared to traditional technical systems. These include:

  • a freely-available iPhone application for measurement upper arm movements -- ErgoArmMeter
  • a wearable system embedded in smart clothes for measuring and assessing the postures of upper arms and trunk  -- the Smart Workwear system,
  • a smartphone application connected with wireless IMU sensors for wrist velocity assessment of hand-intensive work (currently being developed).

In addition, I also look at how to use these wearable systems and provide feedback to workers in order to improve their work technique and reduce undesirable strains on the body.


Teaching portfolio

I have supervised master students from the medical engineering program and from Technology, Work and Health program.

I teach lectures and laboratory sessions in courses on ergonomics and prevention of musculoskeletal disorders.
