Profile Introduction

Dr. Giulivi’s expertise is in the area of mitochondria, bioenergetics and free radical biochemistry. This is reflected in >120 publications with more than 7,000 citations in peer-reviewed journals in the chemistry-biochemistry field of mitochondria and free radicals. She has worked on mitochondrial biochemistry since her undergraduate years, and more recently, her focus is on the impact of intermediary metabolism in neurobiology and dietary deficiencies (thiamine), neurodegeneration and neurodevelopmental and neurodegenerative disorders (autism, Huntington’s, fragile X tremor and ataxia syndrome). The effect of gene x environment interaction in autism was explored by using as a model a flame retardant (BDE-49), in which we reported that this additive effect causes a direct disruption of the mitochondrial function at low nM concentrations, further compounded by a genetic background exhibiting a subclinical mitochondrial dysfunction. The study of metabolism in these models is accomplished through the use of a variety of biological models (isolated mitochondria, primary cell culture, established cell cultures, animal models including conditional knock-in and transgenic, human patients’ samples) and using state-of-the art technology (metabolomics, bioinformatics, mitochondrial bioenergetics). Dr. Giulivi has trained a variety of students during the last 20 years, spanning from high-school students (summer internships), undergraduates and graduates to postdoctoral fellows.

Research Interests

Understanding the mitochondrial mechanisms underlying pathophysiology

We explore the mechanisms underlying mitochondrial biology in different pathophysiological cases including autism, schizophrenia, Huntington's and fragile X tremor and ataxia syndrome.
