Without funding it is practically impossible to conduct research in which experiments are necessary to verify hypotheses.  Our laboratory has been able to support our students' research thanks to the support from various sources that are not tied to any specific research theme.  Moreover through research collaboration students conduct their experiments at collaborated universities where costs are lower and carry out the analytical part at our laboratory.  

This page provides a list of research and their sponsors and a list of research being conducted by students.
