Professor Vollum's research interests are wide, encompassing the following topics: long-term deflections of reinforced concrete slabs, beam-column joints, shear in beams, punching shear, strut and tie modelling, non-linear finite element analysis, the design of reinforced concrete slabs, control of cracking induced by early age thermal contraction and subsequent shrinkage, structural design. 
He has developed a method for predicting the deflection of slabs that takes construction loading into account. The numerical work was calibrated with data from the in-situ concrete building at BRE Cardington with which he was closely involved. More recently, he led an EPSRC project (EP/D505488/1) which developed a design method for using concrete blinding as struts in cut and cover excavations.

Recent work has focused on punching shear in flat slabs as well as shear enhancement near supports of beams.Currently, he is co-leading an EPSRC project (EP/T004142/1) into the cracking behaviour of reinforced concrete elements subjected to the restraint of imposed strains. This is a joint project with the University of Leeds (EP/T004185/1).
