Marcus D. Goncalves, MD, PhD

As an endocrinologist and biomedical researcher at NYU Langone, I am dedicated to understanding and treating the complex interplay among metabolism, cancer, and the endocrine system. My passion lies in improving patient health and wellbeing by addressing the intricate metabolic and hormonal issues associated with chronic conditions.

I specialize in managing unintentional weight loss (cachexia), muscle wasting diseases, and metabolic disorders such as diabetes and high cholesterol. Additionally, I provide specialized care for men experiencing hypogonadism (low testosterone). With extensive training and experience in these areas, I am committed to developing targeted therapies that enhance the quality of life for patients with cancer, heart disease, lung disease, and other chronic illnesses. My research also focuses on how dietary sugars, particularly fructose, impact metabolism and contribute to obesity and cancer progression.

Throughout my career, I have been deeply involved in studying insulin processes in various contexts, including endometrial cancer, the liver, and skeletal muscle. My work aims to uncover how insulin resistance contributes to disease progression and metabolic dysfunction, ultimately identifying new therapeutic targets. This integrated approach allows me to contribute to a more comprehensive understanding of metabolic health, enhancing patient care and outcomes.

My journey into medicine was inspired by a profound interest in the mechanisms driving metabolic diseases and a desire to improve patient outcomes through innovative research. As part of the NYU Langone team, I collaborate with a diverse group of professionals, ensuring that my patients benefit from coordinated care. My commitment to patient engagement, responsiveness, and fostering strong partnerships is at the core of my practice. I find immense satisfaction in helping patients navigate their health journeys, ensuring they receive comprehensive and personalized care.
