About this role

We are seeking an R&D Associate to focus on developing high precision methods for isotopic and trace analysis in bulk, nuclear, and environmental samples. The role involves performing research to create prototype, cutting-edge devices and mass spectrometry methodologies or introduction systems. This position is in the Chemical and Isotopic Mass Spectrometry Group within the Nuclear Analytical Chemistry Section.

The candidate will develop new research focus areas, strengthen current programs, and work closely with the Group Leader to identify sponsors and opportunities. Responsibilities include leading projects, developing high precision mass spectrometry protocols, and publishing scientific papers. Focus areas include sample introduction, collision technology, isotopic analysis, and high throughput methods.

The CIMS group has a history in material analysis since the early 1960s and operates in the Ultra Trace Forensic Science Center. Facilities include over 10,000 square feet of cleanroom space, automated separation systems, and advanced labs across campus. Available instruments encompass MC-ICP-MS, TIMS, triple quad, glow discharge, IRMS, and various sample introduction systems.

Work contributes to advancing trace and ultra-trace material characterizations using high precision analytical methodologies. The role supports material signatures, age dating, standard production, and system applications. Familiarity with inorganic mass spectrometry sample preparation is essential.

Requirements

Expertise with magnetic sector-based mass spectrometers including single and multi-detector platforms
Experience with inductively coupled plasma (ICP) and glow discharge (GD) ionization sources
Familiarity with inorganic mass spectrometry sample preparation
Ability to develop high precision mass spectrometry protocols
Knowledge of sample introduction for solid and/or liquid samples
Experience in isotopic analysis, collision and mass shifting technology, or high throughput analysis
