Objective:
I am looking for a career in Chemistry. I want to work for an organization where I will continue to learn and grow, advancing in my career.
Education:
Associate of Science in Chemistry
Laredo Community College, Laredo Texas
Graduated July 2010
Bachelor of Science in Chemistry
Texas A&M International University, Laredo Texas
Graduated December 2013
Work History:
Pfizer, Inc.
Position: Chemist Quality Analyst 10/2016-12/2016
Job Duties: At Pfizer my responsibilities included logging in incoming samples from manufacturing in log book. Conducting test based on sample, sample ticket, and batch record. In-Process testing included: titration, conductivity, oxidation, HPLC, IL, TOC, and polarimeter. Once testing was complete all data and instrumentation was recorded in the batch record and verified. I reviewed batch records insuring all tickets and testing was complete and everything was verified prior to releasing. I conducted daily/weekly room check which consisted of refilling pH buffers and bottle water, checking weight on balances and logging it appropriately, checking eye wash station, flagging expired or restandardized solutions. I also correlated and restandardized solutions following strict guidelines. I performed daily buffer, polarimeter, and IL check. I also maintained training files. Followed strict guidelines specific to In Process Chemistry and followed Standard Operating Procedures/Test methods. I worked in fast pace environment, multitasked several samples at one time. Informed manufacturing (call or page) when testing was complete and cleared the sample for continued production. Performed GMP (Good Manufacturing Practices) daily. Collected water throughout the facility and cleanroom areas for daily water testing.
Concord Supply, Inc.
Position: Quality Assurance Manager 8/2016-8/2016
Job Duties: At Concord Supply, Inc. my job duties consisted of inspecting and testing incoming raw materials (PP/PE Resin and Scrim). This included testing Resin for Melt Flow index and checking weight (GSM - grams per square meter) of Scrim; as well as checking profiles of incoming scrim rolls. I also did testing on in-process and final production through trapezoid tear test, Stress, Strain, Elongation, and Strength testing. Produced sketch for ASTM testing substitution. Did visual inspection on out going finished product. Maintained daily log of scrap material, as well as performance of operators by making graphs indicating scrap produced by each operator. Contacted suppliers for bad quality merchandise. Participated and implemented safety guidelines. Did daily walk through to the lines to insure printing met quality standards. Issued Certification of Analysis for incoming and out going products. Maintained a clean and orderly laboratory setting.
Flexcon Industrials, LLC
Position: Quality Assurance Technician 3/2016-8/2016
Job Duties: My job duties at Flexcon includes using established test procedures to evaluate incoming raw material (i.e., Films, Liner, Foil, adhesives, and other substrates, etc.), work-in-process, and finished goods. These tests include viscosity, peel test, linear release, coat weight, thickness, percent solids, moisture retention, DSC, FTIR, as well as visual inspection. Verify and approve all production in on-going as well as converting. Test finished goods versus established specifications or drawings, and issued certifications (Certification of Compliance) as required. I also issue holding tags as needed and maintain current Tag Log in JD Edwards. I maintain the lab in a clean and orderly manner, as well as assume duties of other quality technician during absences.
Boral IP Holdings
Position: R&D Lab Technician 11/2014-3/2016
Job Duties: While at Boral my primary responsibilities involved accelerated durability testing of various building materials including polymer composites, fiber cement and engineered wood. Testing typically focused on the effects of water absorption, freezing-thawing, ultraviolet radiation and heat on various physical properties of the materials including flexural strength, elastic modulus, impact resistance and surface hardness. I was also responsible for the evaluation of various coatings and overlays on polymer composite siding and trim. After exposing materials to accelerated weathering conditions, various types of analyses, such as scanning electron microscopy, were used to identify failure mechanisms. While at Boral I gained expertise with the operation and routine maintenance of many types of testing and analytical equipment and frequently my duties included data analysis and reporting results.
Southwestern Research Institute 5/2014-10/2014
Position: Lab Technician
Job Duties: My primary job duties at SWRI included running analysis on fuels such as gasoline and diesel. I mainly conducted Fluorescent Indicator Absorption (FIA) analysis, used to determine the quantity of aromatics, olefins, and saturates in fuels. I also occasionally ran flashpoint, pour point, heat of combustion and performed distillation, which measures the point at which the fuel ignites due to temperature, and the amount of energy released when a fuel has undergone complete combustion.
Texas A&M International University 1/2011-12/2013
Position: Student Research assistant
Job Duties: As a Student Research Assistant my focus was on two research projects. The first one involved antimicrobial activity of herbal extract taken from tropical medicinal plants and focused on the purification and characterization of a biologically active compound of Fagara Y extract. I used High Pressured Liquid Chromatography HPLC to purify the extract, Gas Chromatography Mass Spectrometry (GC-MS) to identify and quantify the extract, and Ultraviolet-Visible Spectroscopy (UV-VIS) to detect aromatic compounds. These results were presented during a professional symposium. The second project concerned synthesis, characterization and binding of carbohydrate receptors with potential applications in targeted drug delivery, cancer imaging and diagnostics. My main contribution to this study was the synthesis of carbohydrate receptors. My job duties included maintaining inventory, training and supervising students, performing Thin-Layered Paper Chromatography (TLC) to test for purity, preparing various solutions, and performing organic extractions. In this role I gained experience handling hazardous chemicals such as Polyphosophoric Acid and phosphorus oxychloride.
