About  |  Publications  |  Lab Members


Dr. Gonçalo Gamboa da Costa is a research chemist at NCTR. He received his bachelor’s in biology from the University of Lisbon, Portugal, followed by an M.S. in technologic organic chemistry from the New University of Lisbon, Portugal, and a Ph.D. in organic chemistry from the Technical University of Lisbon, Portugal. Following a postdoctoral appointment at the Institute of Cancer Research, Sutton, UK, Dr. Gamboa da Costa became Director of the Laboratory of Mass Spectrometry and Nuclear Magnetic Resonance at NCTR. Dr. Gamboa da Costa has been the principal investigator for several toxicological studies sponsored by the National Institutes of Environmental Health Sciences (NIEHS)/National Toxicology Program (NTP). His area of expertise is the implementation of mass-spectral based analytical methodologies to elucidate mechanisms of toxicity. Dr. Gamboa da Costa serves as the FDA Liaison Officer to the NTP.

Research Interests

Dr. Gamboa da Costa’s research interests are focused on the in-depth toxicological evaluation of food adulterants and food additives. He is the principal investigator of key toxicological studies sponsored by NTP aiming to clarify the combined toxicity of melamine and cyanuric acid. These food adulterants were implicated in the kidney illness and death of large numbers of cats and dogs in the U.S. in 2007, as well as the deaths of at least six infants and the hospitalization of an estimated 300,000 infants in China in 2008. The outcome of Dr. Gamboa da Costa’s research is expected to play a key role in the refinement of the current FDA risk assessment for melamine and derivatives. He has also recently initiated studies that aim to clarify certain toxicological aspects of the food additive, brominated vegetable oil.

The studies conducted by Dr. Gamboa da Costa typically encompass, not only guideline endpoints such as histopathology and clinical chemistry, but also additional endpoints such as the toxicokinetic evaluation of the parent toxicant and its metabolites or the quantification of covalent DNA adducts stemming from genotoxicants, enabling a more comprehensive evaluation of the mechanisms of toxicity.

Given Dr. Gamboa da Costa’s expertise in synthetic organic chemistry and mass spectral-based analytical methodologies, he is regularly invited to collaborate with national and international research teams on a breadth of aspects in the domain of toxicology. He is actively collaborating with research teams in the U.S., Canada, and a number of European countries.
