I am a metallurgist by training, with a doctorate degree and over 20 years experience in research and development, manufacturing, and production, in the
aerospace, automotive, and industrial parts industries. My background
includes Statistics, Total Quality, and Six Sigma.
I started using Excel as
part of my job: doing research, analyzing data, and writing reports.
But I soon became obsessed with all things Excel, first with formulas,
then with VBA, and finally with charts. I was nominated as
a Microsoft Excel MVP in 2001, and renominated every year since.
It turns out that my Excel expertise is in great demand, so for the past five years I've been running my own company, Peltier Technical Services. The company web site
and my blog
comprise a huge library of Excel and charting tutorials. I work on custom applications for various clients, and I've begun marketing small Excel utilities that do charting things that Excel should but doesn't.
