Jacques Dubochet (born 8 June 1942) is a Swiss biophysicist who was awarded the Nobel Prize in Chemistry in 2017, alongside Joachim Frank and Richard Henderson, for developing cryo-electron microscopy for the high-resolution structure determination of biomolecules in solution. This groundbreaking work has been instrumental in the advancement of structural biology, allowing scientists to visualize proteins and other biomolecules with unprecedented clarity, which is crucial for understanding biological processes at a molecular level.

Early Life and Education

Jacques Dubochet was born in Aigle, Switzerland. From a young age, he showed a keen interest in the sciences. He pursued his higher education in physics at the École Polytechnique Fédérale de Lausanne (EPFL), where he received his degree in physical engineering. He furthered his studies in biophysics, earning a PhD from the University of Geneva and the University of Basel in Switzerland. His doctoral research laid the foundation for his later work in cryo-electron microscopy.

Career and Research

After completing his PhD, Dubochet embarked on a career that saw him working in several prestigious institutions across Europe. His early research focused on electron microscopy, but it was his work on vitrification—a process that rapidly cools a substance to prevent the formation of ice crystals—that revolutionized the field of structural biology. By applying this technique to biological specimens, Dubochet and his colleagues made it possible to observe the natural structure of biomolecules without the distortions or damage caused by traditional electron microscopy techniques.

The introduction of cryo-electron microscopy has had a profound impact on the life sciences, enabling detailed studies of viruses, proteins, and other biological entities at an atomic level. This technology has facilitated numerous scientific breakthroughs, including the understanding of the Zika virus structure and the development of targeted pharmaceuticals.

Awards and Honors

In recognition of his contributions to science, Jacques Dubochet has received numerous awards and honors, including the Nobel Prize in Chemistry. His work has not only advanced our understanding of the molecular machinery of life but has also opened new avenues for medical research and drug development.

Personal Life

Beyond his scientific achievements, Dubochet is known for his commitment to education and science communication. He has been a vocal advocate for environmental issues and the responsible use of scientific knowledge. Dubochet's personal journey, including his challenges with dyslexia, has inspired many in the scientific community and beyond.

Legacy
