## **Mar´ıa Molina**

Mar´ıa Molina graduated in Pharmacy from the Complutense University of Madrid (UCM) in 1979, obtained her PhD in Pharmacy in 1985, and completed a postdoctoral stay at the University of Nottingham in the field of yeast genetics and molecular biology. She is currently a Full Professor of Microbiology at the UCM and directs a consolidated research group (Signal transduction in *Saccharomyces cerevisiae*) that also belongs to the Ramon y Cajal Institute for Health Research (IRYCIS) ´ since 2009. Her research is focused on the study of cell signaling in yeast, mainly in MAP kinase pathways, as well as on its use as a platform for the expression of heterologous genes involved in human pathology. She has around one hundred articles in JCR (Orcid 0000-0003-0074-3309), three patents, and has supervised 22 doctoral theses.

#### **Humberto Mart´ın**

Humberto Martin Brieva was born in 1967; graduated in Pharmacy from the Complutense University of Madrid (UCM) in June 1989. He is a Doctor in Pharmacy as of 1994 with Cum Laude honors. He started a tenure track as a Professor in Microbiology at UCM in February 2002 and as a Full Professor in Microbiology in 2020. He has participated in more than 20 research projects and as a co-principal investigator in two national projects. His research work has focused primarily on the study of cell signaling, particularly in the routes mediated by MAP kinases, using mainly the yeasts *Schizosaccharomyces pombe* and *Saccharomyces cerevisiae* as model organisms. This research has been carried out at the UCM and in three stays in foreign laboratories at Scripps Clinic, USA, National Institute for Medical Research, London, and the University of San Francisco, California, USA. He has published about 50 scientific articles (ORCID 0000-0002-6736-3602) and directed nine doctoral theses.
