Senior Researcher/ Yliopistotutkija

Current activities: Member of the Faculty Council. Member of NeuroMuscular Research Center advisory board. Associate Editor of the Journal of Strength and Conditioning Research and SpringerPlus journal. I have also taken a lead role in developing MEG-compatible voluntary force and reflex measurements for the lower limbs and continue to develop research on physical activity and central nervous system functioning.

Career summary

After completing my BSc studies, I worked as a part-time lecturer and research assistant at Leeds Metropolitan University (2003-2004) and then worked as a Strength and Conditioning Coach at Franklin Pierce University (USA) from 2005-2006. I returned to academia in 2006 to complete my MSc and PhD at the University of Jyväskylä. I was a visiting Post-doctoral researcher at Edith Cowan University, Australia in 2013 investigating different forms of resistance training. Since returning to JYU I have been Principle Investigator in externally funded projects (Ministry of Education and Culture and Academy of Finland), as well as being part of the research team for numerous other projects related to resistance training and aging in particular. I am one of the initial researchers to integrate the opportunities afforded by the Centre for Interdisciplinary Brain Research into my research interests (listed above).
