Chiara Mariottini, PhD – Research Assistant Professor, Project Manager

Chiara’s first interaction with research was during her undergraduate years at University of Perugia, in Italy, where she studied Medicinal Chemistry and Pharmacy. Towards the end of her undergraduate studies, she spent approximately a year in the Department of Pharmacology under the supervision of Dr. Carlo Riccardi and Dr. Maria Cristina Fioretti, both known as international experts in cell biology and immunology. It was during her tenure with them that she decided to pursue a career in science.Chiara then moved to Florence, where she specialized in behavioral neuroscience and neuropharmacology and obtained her PhD in Physiological and Nutritional Sciences (with specialty in Neuropharmacology) from the University of Florence. In January 2008, Chiara joined the Department of Pharmacology and Systems Therapeutics at Mount Sinai, New York, for her postdoctoral studies with Dr. Ravi Iyengar. Chiara’s research at the Iyengar Lab focused on the transcriptional mechanisms that can regulate memory strength, flexibility, and persistence in health and disease, with a particular focus on the hippocampus.

Throughout her career, Chiara’s interest in translational research and clinical development has grown considerably, and for this reason, Chiara joined the Krammer Laboratory in November 2018, as an Assistant Professor of Microbiology to work on developing a universal influenza vaccine, in collaboration with Dr. Palese and Dr. Garcia-Sastre. Outside of research, Chiara enjoys any outdoor activity, in particular running and hiking. Chiara loves dogs.
