I use chemistry to support aerospace
Lead Finishes Engineer and Former Lead Analytical Engineer. Using chemistry to solve problems and develop solutions for aerospace.
Hi, my name is
About Me
I am a Materials and Processes (M&P) Engineer focused on finishes and corrosion control in aerospace. I have a PhD in chemistry, with a strong interest in applying chemical principles in unique ways to develop solutions for challenging problems. I am currently working as an M&P Engineer at Boeing in Saint Louis.
My Areas of Expertise:
- Material Analysis
- Light Metal Inorganic Finishes
- Corrosion Control
- Sealants
- Coatings
- AI in Spec Support
Experience
Sep 2023 - present
I am currently working as lead M&P Finishes Engineer on 777X program at Boeing in Saint Louis. I support the program with sealant, coatings, and corrosion control questions, as well as assist in drawing reviews. I also support the vast majority of programs on-site with emergent issues.
Lead Analytical Chemistry Engineer
May 2015 - Sep 2023
I supported all programs at Boeing STL site as well as sites across the enterprise and outside Boeing with analytical chemistry work, leading a lab of 3-5 engineers solving difficult problems for our customers. Expertise with GC/MS, IC, ICP/OES, FTIR (ATR,Microscope), as well as experiment design and data interpretation support.
Oct 2013 - May 2015
Worked as a scientist supporting primarily LC/MS method development and also other chromatography for non-routine, challenging matrices and analytes. Typical tasks include method development, reverse-engineering, quantification, etc. across consumer products, pharmaceuticals, and food, amongst other industries. Additionally worked with FTIR, ICP/OES, NMR, SEM, and wet chemical methods.
- Developed two standard analytical methods (SAMs) for future analysts.

Peer-Reviewed Papers
Featured Synthesis of 2,5-Substituted Siloles and Optical Study of Interactions with Mercury(II), Copper(II), and Nickel(II) Cations
Authors: James B. Carroll, Janet Wilking
Organometallics 32 (6): 1905-1912 (2013)
Several 2,5-diaryl-1,1-dimethyl-3,4-diphenylsiloles (with aryl = p-cyanophenyl (1), m,p-bis(methylthio)phenyl (2), p-N,N-dimethylaminophenyl (3), 2,2′-bipyridin-6-yl (4)) were synthesized and characterized by UV–vis, fluorescence, and NMR spectroscopy, along with crystal structure determinations for 1 and 2. Compounds 1–4 in methylene chloride were combined with 1–10 equiv of M(ClO4)2 (M = Ni, Cu, Hg) in methanol, and the resulting solutions were monitored by UV–vis and fluorescence spectroscopy.
Synthesis, Characterization, and Crystal Structures of 1,1-Disubstituted-2,3,4,5-tetraphenylgermoles That Exhibit Aggregation-Induced Emission
Authors: Teresa Bandrowsky, James B. Carroll, Janet Wilking
Organometallics 30 (13): 3559-3569 (2011)
A series of 2,3,4,5-tetraphenylgermoles with different 1,1-substituents have been prepared, and their UV–vis absorption and fluorescence spectral profiles in solution were determined. A thin-layer chromatography based method was used to measure their solid-state luminescence.
Synthesis and Characterization of 3,6-bis(alkynylaryl)-9,9-diphenyl Substituted Silafluorenes and Germafluorenes
Authors: Stephan Germann, Nigam P. Rath, Teresa Bandrowsky, James B Carroll, Janet Wilking, et. al
Journal of Organometallic Chemistry 1041 : 123849 (2025)
DOI: 10.1016/j.jorganchem.2025.123849
A series of luminescent 3,6-disubstituted-alkynyl(aryl)-9,9-diphenylsilafluorenes and -germafluorenes have been synthesized from the lithium-halogen exchange reaction of 5,5’-dibromo-2,2’-diodo-1,1’-biphenyl followed by a ring closure reaction with Ph2ECl2 (E =Si, Ge). A subsequent Pd-catalyzed Sonogashira coupling reaction with a terminal p-substituted(aryl)alkyne afforded the 3,6-bis(alkynyl)aryl-9,9-diphenylsila- and germafluorenes.
