The Norwegian University of Life Sciences (NMBU) was first established in 1859 as the Norwegian agricultural post-graduate college. The organisation has undergone several changes since then and from 1.1.2014 the Norwegian Veterinary College fusion with the University of Life Sciences (UMB) to form the NMBU. The Norwegian name of the university was changed from Universitet for miljø- og biovitenskap (UMB) to Norges miljø og biovitenskapelige universitet (NMBU). UMB had 7 departments and no faculties. Since 1.1.2014 NMBU has three faculties and 13 departments.

The institute for mathematical sciences and technology (IMT) is one of the seven departments under the Faculty of Environmental Sciences and Technology. IMT has 5 research sections, where the Environmental technology and Building technology is one of themn with one established research group for water and environmental technology with focus on: water supply – treatment processes and transport systems; Conventional and decentralized wastewater systems, Urban hydrology and Water Hygiene and health risks. The group is leading several international projects and has internationally leading research in modelling and control of treatment processes. IMT has several pilot research facilities in-house, relevant for it’s research groups. These include experimental facilities for water and wastewater treatment, biogas production, renewable energy research etc.

IMT has the highest number of students (over 1000 of a total of 5700) among the 13 departments of NMBU. IMT has 70 PhD students at present of the total of about 500 at NMBU. There are many different nationalities at NMBU; the international students make up 20% of all students at the University. Of the 1160 University staff, more than half hold scientific positions.  For further information please consult the website :
