About me

I am professor of optoelectronics (semiconductor technology). Optoelectronics serves as the core technology for the majority of light driven photonics applications. Optoelectronic devices are used to transform electrons into photons, modulate and amplify light beams, transfer photonic signals to electronic domains, or convert solar light to energy.

My personal motto is “MAKE A DIFFERNCE!”. I follow this by identifying early stage emerging areas of research concerning III-V optoelectronics materials and novel device concepts. I target long-term impact by establishing technology development roadmaps starting from basic material science and ending with proof-of-concept applications, such as the use of semiconductor lasers in dermatology, sensing of environmental pollutants, and high efficiency solar energy conversion. 

OSA Fellow SPIE Fellow


I am heading the research work at the “ORC-team” (Optoelectronics Research Center ), part of photonics community in Physics Unit. ORC is one of the leading optoelectronics research groups in Europe with more than 30 years of activity centered on the use of molecular beam epitaxy and the development of novel optoelectronic devices, such as laser diodes or solar cells. It is also the cradle of laser industry in Tampere and Finland.

I am responsible for three MSc-level courses in the area of optoelectronics and photonics and I act as lead supervisor or co-supervisor for 12 PhD students. I am PI of an ERC AdG project (AMETIST), and several other projects funded by the Academy of Finland, Business Finland, the European Commission (H2020), and the European Space Agency.
