I completed a BSc in Biochemistry at the Universidad Autónoma de Madrid (Spain) in 2018, and I am currently an Immunology Intern at the Hospital Universitario de La Princesa.
I took my first steps in science in the last year of college, when I performed my end-of-degree project about the pre-TCR signaling pathway and its possible implication in T acute lymphoblastic leukaemia (T-ALL) at the Centro de Biología Molecular Severo Ochoa (CBMSO).
After that, I started my studies in the clinical setting and I am currently working as an Immunology Intern at the Hospital Universitario de La Princesa. In the course of my internship the multidisciplinary research caught my attention. For that reason, I got interested in Dr. Jiménez-Saiz’s research lines and decided to begin my PhD in his group.

I graduated in Biochemistry at Universidad de Granada (Spain) in 2016. Then I moved to Madrid to complete a MSc in Molecular Biomedicine at the Universidad Autónoma de Madrid (Spain).
My master’s project was under the supervision of Dr. Pilar Martín at CNIC with a Research Scholarship for Master students from CNIC. My work focused on studying experimental autoimmune myocarditis in mice with mitochondrial alterations. During this period I became very interested in immunology, metabolism and cardiovascular disease.
Currently, I am doing a PhD in Molecular Bioscience with a FPU grant in Sánchez-Madrid´s Lab. My PhD work is focused in immunometabolism of amino acid transporters but I also collaborate in projects about psoriasis, contact dermatitis and allergy, the latter with the Jiménez-Saiz Lab.
Elisa Sánchez Martínez

I am an undergraduate Biology student at the Universidad Complutense de Madrid (UCM, Spain). I am currently studying the last year of the degree, doing the health specialty.
I have been interested in different projects related to nutrition and antibiotic resistance. Hence, I participated in activities related to this topic organized by the Consejo Superior de Investigaciones Científicas (CSIC, Spain) and collaborated with the Small World Initiative (SWI) Project.
Immunology has always been one of my curiosities. I met Dr. Jiménez-Saiz doing biochemistry laboratory, which prompted me to choose his group for beginning to develop myself as a scientist. In the future, I would like to be a researcher, focusing my studies in clinical immunology.

Research
Our goal is to understand immunological principles of type 2 immunity in the context of allergic disease, particularly as it pertains to acute allergic reactions (anaphylaxis) and its modulation by the microbiota, the maintenance of IgE immunity (memory responses), and the impact of allergic disease in the development of other pathologies.
Our lab has a marked translational identity, which has been achieved through research in pre-clinical models of allergic disease and a close collaboration with clinicians.
We are constantly seeking for new members that are highly motivated and have strong critical thinking skills!
