Expert is an expert in the manipulation of DNA, total RNA and mRNA, including isolation from different sources, such as saliva, brain, muscle, liver and blood, and their analysis by electrophoresis and Southern and Northern blotting. He has extensive experience in constructing cDNA and genomic DNA libraries using different systems and vectors. He also has a great deal of expertise in screening such libraries, isolating, subcloning and sequencing clones.

Expert’s Ph.D. thesis focused on the cloning, sequencing and expression of the chicken alfa-tropomyosin gene in different tissues during development. He has constructed and screened genomic libraries of M. leprae. Expert has taught practical and theoretical molecular biology at the undergrad and graduate level for over 15 years, and basic biochemistry for medical students for more than 23 years. This has allowed him to remain up-to-date in all the major developments in these areas of research. He edits and maintains a Web page dedicated to the general public where he talks about the impact of biotechnology on medicine and life in general.

He coordinated four International courses in genetic engineering sponsored by the Biotechnology Program for Latin America (BIOLAC) of the United Nations University. Those courses dealt with nucleic acids technologies, from DNA and RNA isolation to cDNA and genomic libraries construction, screening and gene isolation and sequencing. They also included PCR amplification and construction and use of DNA probes. During the last six years, Expert has been dedicated to the study of the relationship between stress, genotype and hypertension; in particular, the genotypes of the angiotensin I-converting enzyme (ACE), angiotensinogen, NO synthetase and other genes related to blood pressure homeostasis. In this research he extensively uses DNA isolation and storage, PCR amplification and electrophoresis. This research has led to six theses.

Recently, Expert has started a pharmacogenomic study analysing the relationship between different genotypes of the Renin-Angiotensin system and the response to drugs in hypertensive patients. In collaboration with his group, he is constructing a DNA database of different types of cardiovascular patients and normal controls. All patients are voluntary and sign an informed consent form and the confidentiality of the data is secure. He is also finishing a textbook for Spanish-speaking medical students, a vital necessity since most of the biochemistry textbooks are translated for English and dedicated to students with backgrounds that are vastly different from the Latin American students.
