Alice Gathogo explores advanced X-ray science through NEPHEWS
From 1–6 July 2026, Alice M. Gathogo, an MSc Physics student at Egerton University (Kenya), joined researchers at European XFEL through the NEPHEWS Twinning Programme, participating in an experiment at the SPB/SFX instrument under the supervision of Dr. Chan Kim and Dr. Tokushi Sato.

Alice’s research focuses on computational and experimental studies of perovskite solar cells, with the goal of developing more efficient, stable and affordable photovoltaic technologies. Motivated by the opportunity to gain hands-on experience with world-leading research infrastructure, she applied to the NEPHEWS Twinning Programme to broaden her scientific perspective and learn advanced experimental techniques that are not available at her home institution.
During her stay, Alice was introduced to the operation of the European XFEL, gaining first-hand insight into how ultrashort X-ray pulses are generated, transported and used to investigate materials. Working alongside an international team of scientists, she experienced every stage of an XFEL experiment, from beamline preparation and sample delivery to detector operation and data acquisition. The experience allowed her to connect theoretical concepts with practical applications in a large-scale research environment.
Reflecting on the twinning experience, Alice highlighted the multidisciplinary and collaborative nature of the experiment as one of its most valuable aspects. Beyond learning advanced experimental methods, she strengthened her laboratory skills, scientific communication, and understanding of how international research teams work together to address complex scientific questions.
The knowledge gained during the visit will directly support her MSc research. In particular, the exposure to advanced X-ray techniques has provided new ideas for characterising materials used in perovskite solar cells and has helped her identify experimental approaches that could complement her ongoing work. Alice also looks forward to sharing her experience with fellow students and researchers at Egerton University, helping to introduce modern photon science methods to her academic community.
The NEPHEWS Twinning Programme continues to provide early-career researchers with unique opportunities to participate in experiments at Europe’s leading photon and neutron research infrastructures, fostering international collaboration, knowledge exchange and the development of the next generation of scientists.
