I teach analytical and organic chemistry and instrumental analysis courses to biology, environmental and chemistry students. I got my BS at Universidad Central de Venezuela, in 1992. While there, I was a teaching assistant for analytical chemistry courses and after graduation I taught quantitative analysis laboratory. After that, I got my Masters and Ph. D. at the University of Massachusetts, Amherst.
Research has been an important part of my career. For my undergraduate thesis I optimized and evaluated a method to analyze lubricating oils by AAS and ICP-OES. My graduate research work was to modify a GC-AED system to improve detection limits and selectivity in the determination of nitrogen compounds. Additionally, I worked in the determination of biomarkers in soil and geological samples, by GC-MS. After my Ph.D., I worked as postdoc first to determine carboxylic acids in drinking water by HPLC-MS, and later in the development of a microwave extraction method to analyze solid waste samples, comparable to an EPA method, but 10 times faster.
My research interests are to develop and modify novel methodologies of analysis, for a wide variety of samples, especially environmental samples. To carry on research we have instrumentation laboratories equipped with GC, HPLC, UV-VIS, IR and AAS systems, among others, used also for teaching. This instrumentation enables us to do metal determination along with determination of organic compounds, such as pesticides. Additionally, as analytical chemist, I support the work of other researchers and provide analytical services to several to local industries.
