Research focus:

The research of my group is focused on uncovering the mechanisms, regulation, and function of the three eukaryotic SMC complexes: cohesin, condensin, and Smc5/6. In addition, we also study how Topoisomerases complement SMC complexes enabling critical functions during DNA replication and repair, as well as chromosome segregation. Employing both in vitro and in vivo approaches, our research aims to understand SMC and Topoisomerase mechanisms and explore strategies to target these complexes with clinically relevant drugs.

About me:

I joined the LMS attracted by its core funding, exclusive research focus and support of discovery science with implications for disease. These aspects perfectly matched my goal of addressing questions that required long-term research support and innovation.

My awards and achievements:

EMBO Member

Impact of my work:

Research on human SMC complexes holds promise for medical advances, drug development, and therapeutic applications. Insights into SMC function may lead to targeted therapies for genetic disorders and cancers. Understanding SMC complex mechanisms can also impact biotechnology and provide critical knowledge of fundamental cellular processes.

My Research

DNA motors

Our laboratory is dedicated to unraveling the intricate mechanisms by which cells organize and manage their extensive DNA molecules. Our primary focus is on understanding the roles of Structural Maintenance of Chromosomes (SMC) complexes and topoisomerases. These essential factors are crucial for the regulation of DNA and chromosomes, impacting a wide range of DNA-centric processes such as transcription, replication, repair, and chromosome segregation. Our ultimate goal is to translate this fundamental knowledge into the development of novel therapeutic strategies targeting these components in various diseases, including cancer and viral infections.
