Research Assistant Clinical trial: weight loss, energy metabolism and metabolic health

Welcome to Maastricht University!
Are you passionate about obesity and metabolic health, and eager to contribute to the development of improved weight loss strategies in people with obesity? Then join our highly dynamic international team at the Department of Human Biology at Maastricht University. As a research assistant, you will contribute to a clinical study investigating the effects of a novel obesity management drug on energy metabolism compared to similar weight loss achieved by a low-energy diet, and elucidate the underlying mechanisms. This position will allow you to perform cutting-edge research in the field of obesity management, and work in close cooperation with the Steno Diabetes Center Aarhus and industry.

Research Assistant Clinical trial: weight loss, energy metabolism and metabolic health
 

• Our goal: The aim of this project is to determine the effect of a novel, unimolecular GLP-1 and amylin receptor agonist on energy metabolism and cardiometabolic health compared to diet-induced weight loss or placebo in adults living with obesity, and examine underlying mechanisms.
• Your colleagues: You will work in a young, international and multidisciplinary research group specialized in obesity and metabolic health, embedded within the Department of Human Biology (NUTRIM), Faculty of Health, Medicine and Life Sciences at Maastricht University. As part of a team involved in the execution of a two-center randomized clinical trial, you will also collaborate with colleagues from the Department of Internal Medicine, Steno Diabetes Center Aarhus and Novo Nordisk. This practical study offers an excellent introduction into clinical research and may serve as a mutual acquaintance for those who are interested in progressing to a PhD position within our research group.
  
  

Obesity is a complex chronic disease that acts as a gateway to many noncommunicable diseases. Weight loss is the most effective strategy to improve cardiometabolic health and quality of life in people with obesity, and can prevent or reverse several obesity-related complications. During weight loss, biological changes such as metabolic adaptation (reduction in energy expenditure below predicted values) may hamper further weight loss and weight loss maintenance. The extent of such biological adaptations may depend of the way weight loss is achieved.

As a research assistant, you will contribute to the execution of a clinical trial investigating the effects of a unimolecular GLP-1/amylin receptor agonist on energy metabolism and cardiometabolic health compared to similar weight loss achieved by a low-energy diet. Our basic and translational research group (headed by Prof. G.H. Goossens and Prof. E.E. Blaak) accommodates 5 permanent scientific staff members, more than 10 PhD students and post-doctoral fellows, 2 technicians and support staff, and has access to state-of-the-art research facilities to perform human intervention studies, cell culture experiments, and molecular analysis. In this project, you will work closely together with a PhD student, post-doctoral fellow, another research assistant, a dietician, technician and clinician.


The Department of Human Biology is part of the Institute of Nutrition and Translational Research in Metabolism (NUTRIM), within the Faculty of Health Medicine and Life Sciences (FHML) of Maastricht University. The central research theme of the Department of Human Biology is Healthy Living with Obesity, Sarcopenia, Energy metabolism and Cardiometabolic Health as spearheads. NUTRIM catalyses translational research into metabolic and chronic inflammatory disorders, and aims to contribute to health maintenance and personalized medicine by unraveling lifestyle and disease-induced derangements in metabolism, and by developing targeted nutritional, exercise and drug interventions. Within NUTRIM, approximately 400 scientists including 245 PhD students, and an additional 70 support staff members work interdisciplinary together in 16 biomedical, clinical, and behavioral-science departments. NUTRIM is partner within unique consortia in which academia, industry and the government join forces to stimulate the transfer of knowledge generated in fundamental research to Dutch industry, thereby strengthening its innovative power and competitive strength.
