Personal Statement

My major long-term career goal is to make important discoveries in the field of cardiovascular physiology that are ultimately translated to therapies that improve people’s lives. I plan to make these contributions by becoming a leading cardiovascular scientist with an independent academic research program and by training the next generation of cardiovascular scientists. My current research aims to identify the powerful mechanisms by which activation of central nervous system leptin-melanocortin pathway improves cardiac function after I/R. Unraveling these mechanisms will provide new physiological insights into the role of leptin-melanocortin system in regulating cardiac metabolism and overall function and may provide a promising new therapeutic approach for improving cardiac function and reducing morbidity and mortality after myocardial infarction.

Contributions to Science

During my undergraduate studies, I had the opportunity to work as research assistant at the Dept. of Physiology of the Sao Paulo State University. I spent 3 years at Dr. Juliana De Gobbi’s laboratory studying the integrative role of the central nervous system in the maintenance of body fluid and cardiovascular homeostasis in an animal model of aortic regurgitation. During this period, I studied the effects of a selective serotonin re-uptake inhibitor, paroxetine, to improve cardiac function and sodium appetite in rats with heart failure induced by aortic regurgitation. As soon as I received my bachelor’s degree, I enrolled in a master degree program in the same field of research aimed at understanding the mechanisms involved in the cardioprotective effect of paroxetine after aortic regurgitation.

In order to get my Ph.D., I decide to move to another university to enroll in a graduate program in Physiology at the School of Medicine of University of Sao Paulo in Ribeirao Preto, SP. During graduate studies, my research focus was on characterizing myocardial lesions caused by ischemia/reperfusion in rats. I also dedicated a significant part of my time to improve my skills with important techniques used for cardiac function and evaluation of autonomic nervous system balance such as echocardiography and heart rate variability analysis. These techniques gave me the opportunity to collaborate with scientists in different areas of cardiovascular research helping them with acquisition and analyses of cardiac function data in different animal models.

In 2020, I joined Dr. John E. Hall’s laboratory at the department of Physiology and Biophysics of the University of Mississippi Medical Center for my postdoctoral training. Due to my expertise in myocardial ischemia/reperfusion (IR) injury in rodents, Dr. Hall and I decided to investigate the effect of chronic central leptin infusion in animals with cardiac IR injury. This study resulted in a first-author manuscript recently published in the Journal of American Heart Association. I also have worked on multiple projects at Dr. Hall’s lab, resulting in the co-authorship of 1 review article, 9 manuscripts and 3 book chapters. I contributed to expanded our research team knowledge in 4D echocardiography technology and I was honored the Vevo Cardiovascular Research Award 2022 (FujiFilm, VisualSonics®).  Most importantly, I have been given the opportunity by Dr. Hall to design independent research projects and, in 2021, I was awarded an AHA postdoctoral fellowship ($134,236.00). Currently, one of my research goals is to understand how the brain communicates with the heart to improve cardiac function post-IR during chronic central leptin infusion. At this stage of my career, my research interests have expanded beyond the scope of my prior training to investigate the role of brown adipose tissue-derived extracellular vesicles in mediating leptin’s cardiac protective effect. My long-term career goal is to become an independent, productive and innovative scientist within the field cardiovascular and integrative physiology at a research-intensive academic institution.
