GC-MSICP-OESAASFTIRNMR

About

Bachelor of Science in Chemistry with hands-on analytical chemistry experience across GC-MS, ICP-OES, AAS, UV-Vis, FTIR, and NMR instrumentation. Two years of undergraduate research developing and validating analytical procedures for trace heavy-metal quantification (lead and iron) in aqueous matrices — directly relevant to ICP-based heavy-metal testing. Currently lead daily QC and analytical method work in a regulated industrial laboratory, including instrument calibration, sample preparation, calibration-curve construction, technical reporting, and full compliance with chemical safety and waste-handling protocols.

Detail-focused, organized, and bilingual in English and Spanish.

Experience

Laboratory Operations Lead & R&D Chemist - SD Polymers - Macon, GA

(2025-06)

Run daily QC analysis of incoming and outgoing material samples in a regulated industrial laboratory; perform instrument calibration, sample preparation, calibration-curve construction, and full documentation of test results.
Lead method-development work on a formulation R&D program (16+ characterized batches), applying thermal, rheological, and chromatographic analytical techniques to track lot-to-lot performance.
Investigated a contaminated-material incident by identifying an unknown adulterant through analytical screening; documented findings and implemented corrective controls.
Manage chemical inventory, SDS files, compressed-gas cylinders, and waste-handling compliance; oversee daily lab operations and safety protocols.

Applications & Research Technician Intern - Bulk Chemical Services - Sandersville, GA

(2024-05 - 2024-08)

Executed 5 analytical research projects using instrumental and spectrophotometric methods to quantify organic-polymer performance in industrial water systems.
Modified and validated spectrophotometric procedures for trace-concentration determination; performed sample preparation, calibration, QC verification, and chemical waste disposal.
Compiled and verified analytical data; produced technical reports and presented results to chemists, engineers, and management.
