Materials Engineering
I was born in 1991 in Vantaa, Finland and studied Engineering Physics in Aalto University School of Science. I got my Master's Degree in 2016 (Major: Advanced Energy Systems) and Doctoral Degree in 2020 (Major: Engineering Physics). I have a vast experience on renewable energy and energy systems from his studies and work experience.
Currently, I am working at Univeristy of Turku in Solar Energy Materials and Systems -research group as a University Lecturer. My major research interests are to integrate solar photovoltaics (PV) to the existing power system effectively and cleverly and to study how snow affects to the performance of PV in Finland.
My research focuses on increasing the solar photovoltaic (PV) electricity production in Nordic conditions. I aim to develop solutions that are optimize PV production as part of the entire power system. I am a PI in UTU's part of the SnowPower research project (funded by Research Council Finland) and have worked in RealSolar consortium as a researcher.
Overall, I am interested in the energy transition from fossil fuel based system to renewable energy sources, including both studying different clean energy sources and their integration to the energy network.
Corresponding teacher (shared) in courses MTEK0015 Solar Energy Engineering (from 2021 onwards) and MTEK0002 Materiaalitekniikka 2 (2022 and 2024 onwards). Previously, I have been a corresponding teacher (shared) in MTEK0001 Materiaalitekniikka 1 (2023-2024).
Besides my duties as a corresponding teacher, I plan and instruct hands-on contact teaching in student laboratory sessions integrated to freshmen courses, create new teaching material, and develop existing material.
