Dr Bueno joined the University of Worcester in January 2012, after 4 years of Post-doctoral experience at the Institute of Brain Chemistry and Human Nutrition in London, working with Prof Michael Angus Crawford, one of the pioneers in fatty acid metabolism and brain composition.

Whilst in London, Dr Bueno focused on biochemical and neurophysiological hallmarks of disorders that are known to affect the central nervous system, such as Down syndrome, Attention Deficit Hyperactivity Disorder, pre-eclampsia and neural disorders induced by obesity.

Dr Bueno investigated in his PhD the effects of dietary fats on adipose tissue metabolism, and how different types of fat can influence disorders such as inflammation and diabetes. In his MPhil Dr Bueno investigated the impact of surgical removal of fat pads on metabolic adaptations in obesity induced by diet and by neurochemical malfunctioning.

Dr Bueno graduated as a Biomedical Scientist – Medical Modality – from Paulista School of Medicine, Sao Paulo Federal University in Brazil. He has extensive experience in clinical sciences, having worked and taught in a leading Tertiary Referral Hospital. His current area of research includes the biochemistry of dietary fats and their role in oxidative stress, brain metabolism and function. More specifically, Dr Bueno researches the many roles of fatty acids and lipids in the development of mild chronic inflammatory states, including liver disease, diabetes, cardiovascular disorders and neuroinflammation. Dr Bueno also researches the interplay between plant polyphenolic compounds and lipids in metabolic diseases and their potential association with neurological states.

 Dr Bueno is a Scientific Advisor of the Food Standards Agency. In June 2023, Dr Bueno was made permanent Chair of the Joint Expert Group on Additives, Enzymes and other regulated products - AEJEG | Committee on Toxicity (food.gov.uk)
