Principal investigator

Dr. Timo is the PI of the PREP research team. He did already his M.Sc. and Ph.D. theses on PREP (in the University of Kuopio), so Timo has strong background on PREP research. Post doc periods in Helsinki, Belgium and USA teached Timo how to use different preclinical models of neurodegenerative diseases from protein level to animal models. His passion is to find a disease-modifying drug for currently unstoppable neurodegenerative diseases like Alzheimer's and Parkinson's disease.

Docent, senior researcher

Dr. Erik Wallen is the leader of PREP lab Medicinal Chemistry, and has 20 years experience on different medicinal chemistry projects. Erik was also involved with earlier PREP inhibitor development in University of Kuopio, so he really knows what PREP and PREP inhibitor compounds are about.

Post-doc researcher

Dr. Johanna Uhari-Väänänen is the latest member of PREP lab. She did her PhD on alcohol addiction project in University of Helsinki, and will be now working with some novel models in neurodegenerative disases.

PhD student

M.Sc. Tommi Kilpeläinen started as a PhD student in November 2016 and before that he performed his M.Sc. project in PREP lab and was working for a while as a research assistant. His project focuses on clarifying the effects of PREP inhibitor structures on protein aggregation, and Tommi works as a multitalent between medicinal chemistry and pharmacology.

PhD student

M.Sc. Henri Pätsi is the most recent PhD student in PREP lab. He already made his M.Sc. thesis in PREP lab at the beginning of 2018 and has worked as a research assistant after that prior to starting his PhD journey. Henri's project is to find novel PREP inhibitor structures.

PhD student

Tony is currently the most recent member of PREP lab as he started working for his PhD in Business Finland project at the beginning of 2019. His project involves both cellular and animal work.

Commercial champion

M.Sc. Samuli Auno is a commercial champion in the Business Finland TUTLI project. His responsibilities in  PREP lab is to take care of commercialization activities of TUTLI project together with Helsinki Innovation Services. Additionally, he conducts in vitro research activities for the project and handles social media accounts during his stay.
