My primary research interests are in cancer molecular and genetic epidemiology and in population genetics. My research focuses on genetic studies of common cancer types in European populations as well as in cancers that occur disproportionally among Hispanic groups.
My primary research aims include the identification of cancer susceptibility genes and studies on how cancer-associated variants mediate risk. My investigations are highly disciplinary and involve large national and international collaborations and expertise from epidemiology, statistics, and germline and somatic genetics.
I am currently heavily involved in major projects aiming at dissecting the basis of common malignancies including breast, colorectal, endometrial and thyroid cancers using both candidate and genome-wide approaches. I also have leadership positions in the CHIBCHA, COLUMBUS and TCUKIN studies.
The Genetic study of Hereditary Bowel tumours in Hispania and Latin America (CHIBCHA) is an European Union funded initiative that is carrying out one of the largest studies of cancer genetics in Latin American populations. In this study we have collected data and bio-specimens from ~6,000 case-controls samples from Brazil, Colombia, and Mexico. These samples are about to be genotyped with Latino-specific genome-wide SNPs arrays. In CHIBCHA, we also have plans to sequence the complete genome of a number of tumours (and matching normal tissue) collected in the region.
The Thyroid Cancer Genetic investigation in the United Kingdom (TCUKIN) is an UK-wide study, supported by the NCRI, that is carrying out genetic studies of non-medullary thyroid cancer and that represents the largest existing cohort of patients with this common endocrine malignancy. So far, this study has recruited over 2,200 patients for genetics studies.
The Colombian Study of Environmental and Heritable Causes of Breast Cancer (COLUMBUS) is an initiative that aims to discover breast cancer causes in admixed populations. For this study, we recently secured funding, from the GlaxoSmithKline Ethnic Research Initiative, to carry out a large study of breast cancer genetics in populations of mixed Amerindian/European ancestry.
