The XIVth international Congress on Rheology was held in Seoul, Korea from the 22nd to 27th of August, 2004. This conference is held every four years and gathers the most important rheologists from all around the world. Six members from the Chemical Engineering Department of Cambridge University attended the conference: Prof. Malcolm Mackley, Dr. Tri Tuladhar, Bart Hallmark, Yu Wen Chen and Gabriela Hernandez from The Polymers Fluids Group (PFG) and Dean Barker, from the Powder and Paste Processing Group (P3G). A total of 9 papers and 1 poster were presented by this department, including three papers presented by former members (Dr. Rudy Valette, Dr. Jan Engmann and Dr. Peter Martin).

Prof. Malcolm Mackley also organised and chaired one session of the “Rheometry and Experimental Methods” mini-symposium
