Chemistry, University of Texas at El Paso Dissertation: “Conversion of Racemic Ibuprofen to (S)-Ibuprofen” The goal of this research is to develop the dynamic kinetic resolution of (S)-ibuprofen from its racemate applying green chemistry concepts. This research is environmentally benign and involves the use of enzymes as enantioselective catalysts in organic and aqueous solvents, racemization and low temperatures. Enzymes are the promising catalyst for the transformation and production of chemicals due to the high efficiency and ability to catalyze reactions such as hydrocarbon oxidation, desulfurization, dehydration, esterification, hydrolysis, etc., enzymes are appealing for the environmental chemistry (Green Chemistry). Chemistry, University of Texas at El Paso Thesis: “Commercial Resolution of Racemic (S)-Ibuprofen” The goal of this research was to develop and environmentally friendly kinetic resolution process for racemic ibuprofen; however the maximum percent yield of the product obtained was 50 percent based on the racemic starting substrate. Chemical Engineering, University of Chihuahua Mexico Thesis: “Design and Building of a Cooling Tower” This research involved the design and building of a cooling tower to reduce water waste and energy use in the cooling and pasteurization process for cheese industry in the Chihuahuan desert. PROFESSIONAL EXPERIENCE 2006 to Present Research Assistant in the Development of Materials World Modules and a web page design for UG Science Courses ARMY. My research assistantship requires that I develop and edit a scientific web page. Sustainability and Green Chemistry Summer School, Pan-American Advanced Studies Institute (PASI), Universidad Iberoamericana. Mexico City, MEXICO. Organized by ACS Green Chemistry Institute. I attended a 3-week summer course that brought together international scientists to teach and interact with graduate students from around the world. All the courses and laboratories were focused on Green Chemistry and Sustainability. May–Dec. 2005 Internship at the ExxonMobil Research and Engineering Company with the Project "Preparation of Hybrid (Organic-Inorganic) Membranes for Distillate Separation and Solvent Separation from Extraction”. I worked in the Advanced Separation Division (Catalyst Technology), where reactions involving different inorganic materials and organic membranes were developed with the purpose of produce new hybrid materials with superior chemical, thermal stability and selectivity. As result, we obtained a membrane able to remove solvents from the extraction mixture and a membrane able to upgrade the distillate quality to produce diesel from FCC which reduced costs of the solvent recovery and diesel separation. Teaching Assistant of Organic Chemistry Laboratories in the Chemistry Department at the University of Texas at El Paso. During my Master’s studies, (4 semesters and 2 summers) I worked a Teaching Assistant of the Organic Chemistry Laboratories, lecturing for the pre-lab and monitoring the laboratory sessions. During my bachelors on Chemical Engineering I made three internships and one Community Service developing chemistry and chemical engineering tasks as next: Internship in DELPHI: Quality control and design of new products. Internship in Harinas de Chihuahua: Quality control and analysis of final product. Community Service Chihuahua Health Department: Taking samples of foods from restaurants in Chihuahua Mexico city for future microbiological and physical analysis. Internship in Cuproquim of Mexico: Quality Control. Oral Presentation at the 13th Annual Green Chemistry and Engineering Conference in College Park MD. from June 22 to June 25, 2009.
