Apirat Chaikuad is a senior scientist at Frankfurt University. He studied biology at Chulalongkorn University (Thailand) and later did a PhD in structural biology at University of Bristol (UK). He joined the Structural Genomics Consortium at the University of Oxford in 2008 to work with Frank von Delft in the crystallography team. During this time, he successfully developed the newly-minimized BCS crystallization screen by incorporating a novel defined PEG smears method, which is now commercially available.

He was also awarded the Emanoel Lee Junior Research Fellowship from St Cross College and a merit award from University of Oxford. Later, he has joined the team of Prof. Stefan Knapp. His current research interests focus primarily on structural biology and chemical biology of signaling pathway, essentially protein kinases.
