Biography
Jacqueline Freire Machi received her Ph.D. in cardiovascular physiology from University of Sao Paulo, Brazil. Her doctoral work focused on understanding the mechanisms by which metabolic disease triggers cardiovascular dysfunction for the development of therapeutic strategies including exercise. Throughout her career, with approximately 15 years of research experience she developed a solid background in metabolism, autonomics, exercise training and cardiovascular physiology in the context of metabolic syndrome, aging and toxic chemical exposure. During her pre- and postdoctoral studies, she received training on the use of echocardiography for assessment of cardiac function, analysis of autonomic activity of blood pressure and metabolism.
In 2021, Dr. Machi joined Florida Atlantic University Charles E. Schmidt College of Medicine as an Assistant Professor in the department of Biomedical Science. Her short-term research goal is to understand the role of endothelial c-Myc preventing obesity and cardiovascular dysfunction. Her long-term research goal, is to develop an independent research program in obesity-associated co-morbidities to better understand the mechanisms associated with these conditions for development of preventative and therapeutic strategies that can be translated to clinic.
