Our research uses spectroscopic methods, especially Nuclear Magnetic Resonance (NMR) spectroscopy, to probe the molecular basis of interactions between molecules.

Research Interests

NMR spectroscopy is a versatile experimental tool used by several groups at ITQB. Protein expression, purification and analysis provide the lab with something to study. We then use NMR to investigate molecular size and shape, as well as answer which small molecules bind to proteins, and how.

Our primary focus is on using our skills and tools to study two “neglected diseases”, cholera and tuberculosis. In the case of cholera, we are producing a safe cholera toxin in the lab and screening for functional foods that might inhibit the toxicity. Our tuberculosis project is in collaboration with Spanish and Indian collaborators and we are looking for new protein targets and drug leads. Drug-resistant tuberculosis is becoming more prevalent and our society needs new treatments.

In addition to our lab projects, we collaborate with other researchers in ITQB, Spain, Poland, France, Italy, UK and Hungary. We also improve and develop new methods to produce protein samples and conduct NMR experiments. Calcium-binding proteins, at the heart of many physiological signaling pathways, are favorites that are often used as ‘standards’ in the lab.
