Monika Priyadarshini
Postdoctoral Scholar, Genetics
BioI obtained my PhD from the Biological and Environmental Science Division at King Abdullah University for Science and Technology (KAUST, Saudi Arabia) in 2021. I had the opportunity to work with Christian Frøkjær-Jensen on a fascinating research project focusing on the epigenetic regulation of germline genes and the transgenerational inheritance of silencing in C. elegans.
My passion lies in the field of epigenetics, synthetic and molecular biology, and protein biochemistry. I am deeply intrigued by the intricacies of genome organization and am dedicated to unraveling the "rules" that govern it. Additionally, I'm committed to dissecting the molecular and structural changes that take place within chromatin. -

Elisabetta Viani Puglisi
Associate Professor (Research) of Structural Biology
Current Research and Scholarly InterestsViral infections and subsequent host response depend on multiple RNA-protein interaction. My research focuses on the structural and functional characterization of RNA-protein complexes involved in viral infection. Current research aims to understand how the Human Immunodeficiency Virus (HIV) initiates its replication upon host infection. We use NMR spectroscopy and x-ray crystallography to study the structure of the initiation complex, formed by a host tRNA and HIV genomic RNA, coupled with biochemical and biophysical methods to understand functional properties. The goal of this research is to gain a molecular view of HIV replication initiation, and use this information to develop new therapeutic approaches to combat HIV.
