Dr. Marta Shahbazi, a Cambridge-based cell biology expert specializing in early human development, was among nearly 70 people killed in a high-speed train collision in Spain last week. The crash occurred on Wednesday near Urda in Toledo province, south of Madrid, when one train collided with a stationary train on the line connecting Madrid with Seville.

Dr. Shahbazi, 39, was travelling to the southern city of El Rompido, Andalucía, to receive a scientific excellence award from the Spanish Society for Developmental Biology. She was a group leader at the Medical Research Council Laboratory of Molecular Biology (LMB) and an affiliate associate professor at the Cambridge Stem Cell Institute. She had been recognized for pioneering research on the earliest stages of human embryonic development and the mechanisms behind failed pregnancies.

The LMB described Dr. Shahbazi as “an inspiring, talented and passionate scientist” and highlighted her admired role as a “mother scientist” who openly discussed balancing her research career with family life. Colleagues also paid tribute to her contributions and personal qualities. Dr. Roser Vento-Tormo, a collaborator and friend from the Wellcome Sanger Institute, described her as an inspiring scientist and devoted mother, expressing sorrow over the loss and emphasizing the lasting impact of her unfinished work.

The Center for Research in Molecular Medicine and Chronic Diseases (CiMUS) in Santiago de Compostela also remembered Dr. Shahbazi as a "brilliant young researcher," acknowledging her promising scientific career.

The train crash, which resulted in at least 69 fatalities and multiple injuries, marked the second major high-speed rail disaster in Spain this year along the Madrid-Seville route. Following the tragedy, the Spanish government declared three days of national mourning. Prime Minister Pedro Sánchez pledged to conduct a thorough investigation into the causes of the accident.

The incident has prompted renewed concerns about rail safety in the country, with authorities working to determine the factors leading to the collision and to prevent future occurrences. Meanwhile, the scientific community continues to mourn the loss of Dr. Shahbazi and reflect on her significant contributions to developmental biology.
