Lab: Franzini
Background:
My scientific education and research experience have provided me with a strong foundation in organic and medicinal chemistry. During my postdoctoral training, I am becoming a specialist in DNA-encoded libraries (DELs), a cutting-edge drug discovery technology. My master’s studies endowed me with a solid medicinal chemistry background, synthetizing libraries of prospective anticancer and antifungal compounds, several of which have shown promising activity in cellular models. Through my doctoral research, I gained expertise in glycobiology, working on the chemical synthesis of cell surface glycans, their conjugation to proteins, and immunological evaluation of the resulting neoglycoproteins as biomarkers and tools for vaccine development. In addition, I was trained in modern organic synthesis during my industrial internship, working on photoredox catalysis and metal-catalyzed cross-coupling reactions, for hit-to-lead development, lead optimization, route scouting, and compound scale-up. Over the course of these studies, I have attained a variety of high-level technical skills in multiple spectroscopy and spectrometry techniques, biological assays, mentoring and scientific communication.
