About the speaker
In 20 years of research, I have developed a large number of novel micro- and nanofabrication methods, with particular focus on 3D polymer and carbon structures such as photolithography, spray coating, additive manufacturing and pyrolysis. My fundamental technological contributions are highly cited in the micro- and nanoengineering community. In the field of pyrolytic carbon microfabrication my group, currently consisting of 14 members, is among the 3 internationally leading contributors with a significant impact on the future directions in this research field.
I have applied the novel methods to design and fabricate novel platforms for oral drug delivery, diagnostics, stem cell therapy, implants, bioelectrochemistry, energy harvesting and energy storage. As specific examples, a 3D in vitro model with integrated electrochemical measurement of bone cell growth and optoelectrical implants for stimulation of neural stem cells for cell replacement therapy in Parkinson's disease were demonstrated. In the ERC project PHOENEEX, we have developed novel systems for electrochemical energy harvesting and storage, such as on-chip carbon-based microsupercapacitors and microbial solar cells surpassing the state-of-the-art.
