PhD Joana Santos



My research is aimed at understanding the molecular mechanism of the Mycobacterium tuberculosis mutasome, a group of proteins that create mutations in the M. tuberculosis genome that lead to antibiotic drug resistance. For this I use biochemistry, single-molecule methods, and cryo-EM.

Curriculum Vitae:

I performed my bachelor’s studies in Applied Chemistry at the New University of Lisbon. Next, I did my PhD studies in the lab of Pedro Pereira at the Institute of Biomedical Sciences Abel Salazar, Porto. Following this I moved to the lab of Dirk Slotboom in Groningen where I worked as an EMBO post-doctoral Fellow on the structural and biochemical characterization of the bacterial Vitamin B12 membrane transporter and solved its crystal structure. Since February 2018 I have been working as a postdoctoral researcher in the lab of Meindert Lamers.
