RESEARCH INTERESTS

Metrology (the science of measurement) ensures a better quality of life. It plays a vital role in almost everything in our lives such as healthcare, transport, manufacturing, science, trade, energy and safety. Without correct measurements, satisfying our requirements is a challenge. Therefore, my researches are focused on developing technical solutions for metrology-related applications for a better life of the community.
