About
P.J. Rizkallah is a structural biologist whose work bridges fundamental biochemistry and practical crystallographic innovation. His research centers on the molecular mechanisms underlying biological colouration and the development of streamlined methods for protein structure determination. Rizkallah’s landmark review on the lobster shell colouration mechanism—cited nearly 100 times—integrates biochemistry, crystallography, spectroscopy, and microscopy to unravel over 50 years of inquiry into how crustacyanin proteins produce vivid blue hues. This work not only illuminates a classic biological puzzle but also demonstrates the power of multi-technique structural analysis. In parallel, Rizkallah introduced S-SWAT (softer single-wavelength anomalous technique), a data-collection protocol that reduces the number of wavelengths and data redundancy required for phasing, thereby accelerating high-throughput protein crystallography. With 38 citations, this methodological contribution addresses the growing demand for faster, automated structure determination pipelines. Together, these achievements showcase Rizkallah’s dual impact: solving long-standing biochemical mysteries while equipping the structural biology community with more efficient tools for discovery.
