We are the people in Mibira group

Merja Lusa

Ph.D., Group Leader

I got my M.Sc. in radiochemistry from the University of Helsinki and my background is in biochemistry, radiochemistry and genetics. My Ph.D. focused on the effects of microbiota on the environmental behaviour of  long lived radionulides present in nuclear fuel. Our multidisciplinary research team works closely with microbiologists and plant biologists working in domestic research centers as well as in the research institutes abroad combining microbiology, plant biology, radiochemistry and biochemistry. My research focuses on the cellular processes present  in biosorption and -accumulation as well as on the redox processes of environmental contaminants in bacteria particularly in northern environment.

Jenna Kasko

M.Sc., Ph.D. student

I started my Ph.D. studies in the microbiology and biosphere research group (Mibira) in July 2015 working under the supervision of Merja Lusa. My research is focused on uptake and speciation studies of radionuclides and heavy metals in environmental bacteria.

I got my M.Sc. degree in radiochemistry in 2014 at the University of Helsinki. My Master’s degree included minor subject studies in mathematics, physics and geology. After my Master’s thesis I started working as a research assistant in Mibira group and have been group member since then (2014). I also have previous research experience from the studies of transport of radionuclides in the bedrock, and the studies of natural uranium and thorium series. Also both of my Bachelor’s and Master’s theses were strongly related to the migration of radionuclides in the environment and safety of the final disposal of nuclear waste.

Marcus works as a research assistant in the group and is doing his master thesis with a topic of : Leaching of radium from mill tailings  caused by bacteria associated to the acid mine drainage (AMD) .
