I have joined Aston Medical School in 2014 as a Clinical Lecturer (Assistant Professor) in Metabolic Medicine and Nutrition. Overall, I have more than 15 years of research experience in the field of metabolism, nutrition, exercise and endocrinology. I have been responsible for multiple clinical and basic research studies focused in these subjects, whilst I have also been an investigator in several relevant clinical trials. My teaching and research focus on metabolism, nutrition, exercise, obesity, diabetes, cardiovascular disease, non-alcoholic fatty liver disease, polycystic ovary syndrome, public health and chronic stress.
My current clinical and translational research projects aim to further explore the pathophysiology of these chronic non-communicable diseases, identify novel related biomarkers and test new interventions. To date, the research output of my previous and ongoing research projects has resulted in important publications in peer-reviewed medical journals (more than 40 published peer-reviewed papers in PubMed with more than 2500 citations based on Google Scholar), as well as in numerous announcements in national and international biomedical congresses (more than 50 abstracts/posters/presentations at scientific conferences). In addition, I have also authored more than 20 chapters published in high-impact biomedical textbooks.

My teaching subjects focus on the following:
My research projects focus on the following:
Novel biomarkers/adipokines and the adipocyte secretome contributing to increased cardiovascular risk in obesity-related diabetes - effects of nutrition and exercise”, funded by the Aston University 50th Anniversary Prize PhD Studentships Scheme.
“Effects of bariatric surgery on metabolic improvement and remission of T2DM”, funded by the EFSD.
“Effects of obesity on functional limitations and disability”, funded by the DWP.
My current PhD projects at Aston University focus on the pathophysiology of obesity, type 2 diabetes and other obesity-related diseases (e.g. PCOS, CVD), particularly in relationship with nutrition and exercise:
Potential candidates for a research PhD at Aston University are welcomed to contact me with an idea or a fully developed proposal for a research project in the following fields: metabolism and energy homeostasis, nutrition, exercise and health, public health and epidemiology of non-communicable diseases, obesity and obesity-related complications (e.g. type 2 diabetes, cardiovascular disease), polycystic ovary syndrome, non-alcoholic fatty liver disease, mental health and stress.
