Ingrid Dijkgraaf

Associate professor

Dr Ingrid Dijkgraaf has graduated with specialisation in Organic Chemistry at Wageningen University. Subsequently, she has worked on synthesis and biologic evaluation of alpha-v-beta-3-binding peptides and peptidomimetics at the Department of Medicinal Chemistry and Chemical Biology at Utrecht University, and at the Department of Nuclear Medicine at the Radboud University Nijmegen. After obtaining her PhD, she worked as post-doc at the Technical University of Munich, the Radboud University of Nijmegen and The Scripps Research Institute.

Since 2011, she has been working at Maastricht University. Focus of her research is design and synthesis of peptides and proteins using Solid-Phase Peptide Synthesis and Native Chemical Ligation. These compounds are conjugated with chelators, fluorescent labels, and multimodality tags allowing molecular imaging of cardiovascular diseases and cancer. Synthesised compounds are evaluated in in vitro and in vivo studies.
