Postdoctoral Researchers in Enzyme Engineering or Biochemistry


Formic acid is discussed as an alternative form of hydrogen storage. Our concept is to convert CO2 + H2 directly to formic acid via next generation formate dehydrogenases. Our overall goal is to find, express and engineer formate dehydrogenases to become extremely acid-tolerant. To achieve our goal, we established a consortium involving:  

  • Biochemistry (postdoc with Prof. Silvan Scheller, Aalto)
  • Catalysis (postdoc with Prof. Jan Deska, Aalto):
  • Environmental genomics (with Dr. Malin Bomberg, VTT)

Research is carried out at our excellent facilities at Aalto University, School of Chemical Engineering ( The laboratories are situated on the main campus of Aalto University in Otaniemi (short metro-ride from Helsinki). One position is in the Scheller group within the Department of Bioproducts and Biosystems; the other position is in the Deska group within the Department of Chemistry and Materials Science.  

Research description

The postdoc works on the interface towards environmental genomics, with the goal of bringing extremophilic enzymes alive. Key tasks include expression of extremely acid-tolerant formate dehydrogenases, assessment of enzyme parameters in vitro, and to control function via enzyme engineering to push the limit of acid tolerance.


To be eligible, you need to:

  • have a PhD in a suitable field, such as Enzyme engineering, biochemistry, catalysis, organic chemistry
  • be highly committed to science and strive for excellence
  • develop own smart ideas and think independently
  • be able to focus on solving tough scientific problems

Skills, knowledge or interest in some of the following areas are highly appreciated:

  • Enzymology, protein purification
  • Directed evolution
  • Anaerobic biochemistry
  • Spectroscopic methods (X-ray crystallography, NMR, EPR, Electrochemistry)
  • Organic chemistry/synthesis

We offer

  • High-end laboratory infrastructure and friendly colleagues
  • Opportunity to work in a newly established research group
  • Freedom to bring in own ideas
  • Funding for 2 years with option of continuation
