During his M.Sc. and Ph.D. studies, which were performed with Prof. Ilan Marek at the Technion, his research was focused on kinetic resolution, sigma-tropic rearrangements, carbometalation and the selective-cleavage of small, strained materials as a new entry to all-carbon quaternary stereogenic centers. As an illustrative example, they have applied these methodologies to the preparation of the simplest, unnatural, enantiomerically enriched, saturated hydrocarbon possessing a quaternary stereogenic center ((S)-[2H1, 2H2, 2H3]-neopentane). Masarwa was awarded the IUPAC-SOLVAY International Award for Young Chemists and the ICS-Israel Chemical Society Prize for his Ph.D. thesis.
After his Ph.D. studies, Masarwa joined the Department of Chemistry at the University of California, Berkeley in 2013 as a Rothschild and VATAT postdoctoral scholar under the supervision of Prof. Richmond Sarpong. He had worked on the application of metal-catalyzed selective C–C/ C–H bond activations of carvone-derived pinene scaffolds. This methodology can be used to access enantiopure natural product cores, such as those found in phomactin A and suaveolindol, as well as anticancer compounds in the taxoid family.
Ahmad completed his postdoctoral stay in October 2015. After this time, he started as a visiting scholar at the Hebrew University of Jerusalem. In July 2016, Masarwa started his tenure-track faculty position as an Assistant Professor (Senior Lecturer) at The Institute of Chemistry of the Hebrew University of Jerusalem.
