Round Lake, Il

Directed GLP studies as NMR spectroscopist for Baxter Healthcare (under Christina Szabo)o Initiated the routine use of external quantitative referencing for qNMR in the lab.o Developed NMR techniques for the quantitative and qualitative characterization and structural elucidation of polymers and small organic molecules in solution. o Used NMR to eliminate the need for known standard purities when establishing relative response factors (RRF) for chromatographic methods.o Extractables and Leachables – Established the laboratory method for Total Organic Carbon reconciliation of non-volatiles using NMR. This includes general analysis of trace materials in complex mixtures.o Performed NMR analyses of trace impurities in complex mixtures, requiring basic separation/extraction techniques – volatility, polarity, acid/base, liquid/liquid, Sep-Pak, rotovap, centrifuge, distillation, lyophilization.o Initiated outsourcing of routine work to help streamline the NMR lab to handle more important projects.o Firefighting- Root cause investigation and product troubleshooting (investigation of heparin adulteration).o Generated/reviewed/verified GLP/GDP documentation and reports.o Subject matter expert on Quality audits, trained as SCAR owner.o Lab safety inspector.o Software Proficiency - Topspin, VNMR, VNMRJ, Spinsight, and Omnic, as well as C, VBasic, and MS Office.

Naperville, Il.

NMR and IR spectroscopist for Amoco, BP, Innovene, and INEOS under Steve McKennao Refined and modified NMR facility, performed mechanical and electrical (including RF) troubleshooting, experiment scheduling, and submission of progress reports.o Developed NMR techniques and pulse sequences for the quantitative and qualitative characterization and structural elucidation of soluble/insoluble polymers and small organic molecules, organic and inorganic gases, as well as inorganic solids- such as zeolites, ceramics, and catalysts. o Firefighting of product complaints with IR, microscopy, and NMR of trace impurities.o Established sample preparation techniques and performed NMR analysis of adsorbed gases in powders.o Streamlined routine work by writing data acquisition and processing programs to streamline routine work.
