2011 – Present           MARS, Inc.- USDA Globally Program Manager
                       Since 2011, I have led the activities described below, in addition to my other responsibilities as Program Manager, which in itself entails additional direct reports and budgetary accountabilities. These additional managerial responsibilities also include leading a diverse portfolio of research projects in genetics, genomics, agronomy and flavor; these multidisciplinary efforts are quite involved, and require maintaining an active collaborative interface with multiple public research institutions, private companies and development agencies in fourteen different countries.
2004 – 2011                MARS, Inc.- USDA Globally
                                    Senior Research Manager   
                                    Leader of an international breeding, genomics and agronomy program in cacao and other tropical crops in partnership with the United States Department of Agriculture (USDA-ARS), Stanford University and IBM.
                                    Agronomy & Marker Assisted Selection: Established agreements, designed experiments and developed production systems models and dozens of high yielding disease resistance cacao varieties with the participating institutions of an international agronomy, breeding and genomics network. This program is part of the MARS Inc. cacao sustainability initiative. One of its specific objectives is to increase incomes of cacao producers by increasing yields and reducing losses due to fungal diseases in an environmentally friendly manner.                           
                                    Genome Sequencing: To facilitate the identification of genes regulating important agronomic and chocolate quality traits, a partnership between MARS-USDA and IBM was created in 2008 to sequence the entire T. cacao genome. The genome project involved managing research activities among internal and external laboratories involving gene-trait associations relevant to agronomic performance and chocolate aroma characterization. A first draft of the genome was released to the public domain in 2010, and a significantly improved version was reported in Genome Biology in 2013.                                  
                                    Research: I have implemented and/or overseen significant research activities which have led to dozens of scientific publications and the training of 13 post-doctoral fellows and graduate students.

2001 - 2004                MARS, Inc.- USDA                                                               Globally
                                    Research Geneticist 
                                    Research geneticist in an international cacao breeding program in partnership with the United States Department of Agriculture (USDA-ARS).
                                    In an effort to help find ways to increase cacao's disease resistance, MARS Inc, signed a cooperative research and development agreement with USDA-ARS. Its goal was to develop a USDA-MARS managed, internationally (20 countries involved) coordinated, genetic-marker-driven, cacao breeding-research program. This program used a marker-assisted-selection (MAS) approach to select new varieties with resistance to the fungal diseases: Witches' broom (WB), Frosty pod rot, and Black Pod (BP). During the first three years of the program, markers linked to WB, Frosty Pod, BP resistance and yield were identified and multi-hectare hybrid and clone trials, new mapping populations, and promising genotypes were developed.
1999 - 2001                Amedei                                                                    Italy-Venezuela
                                    Provided consulting services as an expert buyer of fine cacao and for the development of new products. The criterion for the selection of raw materials was based on knowledge acquired through the scientific study of Theobroma cacao L. genetic resources.            
1996-2000                  CIRAD                                                                                               France
                                    Postgraduate Research                                          
                                    Performed research on genetic diversity and genetic mapping of important agronomy and quality traits in cacao.


1996 - 2001                 Ph.D. in Molecular Plant Biology
                                    Paris XI, Orsay University, France.
1995 - 1996                M.Sc. in Cellular and Molecular Plant Biology (Diplôme d’Etudes Approfondies en Physiologie Cellulaire et Moléculaire des Plantes).
                                    I.N.A.-P.G. (Paris National Institute of Agronomy, Agro Paris Tech), Paris, France.

1990 - 1995                B.S. in Agricultural Engineering.
                                    U.C.V. (Venezuelan Central University). Maracay, Venezuela.
