Dr 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.
