This research chronicles a scientific journey from chemistry to physics and X-ray crystallography, culminating in contributions to understanding virus assembly and molecular structures.
Area of Science:
- Structural Biology
- Biophysics
- Crystallography
Background:
- Early research focused on X-ray crystallography of organic compounds, developing novel structure-solving methods.
- Investigated phase transitions in steel using numerical solutions of partial differential equations, applying nucleation and growth principles.
Discussion:
- The principles of nucleation and growth were later applied to the assembly of Tobacco mosaic virus (TMV).
- Interpreted X-ray diffraction patterns of TMV, contributing to the understanding of its structure.
Key Insights:
- Developed a new method for solving crystal structures using molecular structure factors.
- Applied physical chemistry principles to biological macromolecule assembly.
Outlook:
- Continued work at the MRC Laboratory of Molecular Biology fostered a sophisticated research environment.
- The trajectory highlights the interdisciplinary nature of scientific discovery, linking materials science to molecular biology.

X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...
