Behind FragMAX is a small, dedicated team with expertise in structural biology, crystallography, fragment screening and data analysis. We work closely with users throughout their projects and are always happy to discuss experimental design, feasibility and interpretation.
Whether you are new to crystallographic fragment screening or an experienced practitioner, you can expect open communication, practical advice and a collaborative approach.
Tobias Krojer leads the FragMAX platform and if you are considering a project at FragMAX or would like to discuss feasibility, Tobias is your first point of contact. Tobias also holds a group leader position at Science for Life Laboratory (SciLifeLab) and his research centers on structural chemical biology, experimental method development, and laboratory automation.
Tobias trained as a protein crystallographer at the Max Planck Institute of Biochemistry and earned his PhD from Cardiff University. He completed postdoctoral studies at the Institute of Molecular Pathology in Vienna. In 2009, he became a Team Leader at the Structural Genomics Consortium (SGC) at the University of Oxford where he contributed to a wide range of initiatives. During his time in Oxford, he also supported development of Diamond Light Source’s XChem facility as a visiting scientist.
Afshan Begum is a structural biologist and research engineer in the FragMAX group at MAX IV Laboratory. Afshan supports and drives user projects in the lab and at the beamline. Her work focuses on protein crystallization, crystallographic fragment screening, and structure-based ligand analysis.
Afshan has extensive experience in protein crystallography, single particle cryo-EM, and biophysical characterization of proteins. She has worked across multiple European research environments and on a wide range of scientific topics.
Kevin Rollet joined the FragMAX team as postdoc in November 2024. He is working on fragment screening campaigns to target enzymes from the flavivirus family. After completing a PhD in molecular and structural biology, Kevin acquired expertise in serial synchrotron X-ray crystallography at the FMX beamline (NSLS-II, NY). His interests include crystallization of biological macromolecules, crystallographic fragment screening and room-temperature data collection strategies.
