About the Author

My name is Brad Larson and I currently reside in Madison, Wisconsin (U.S.A.). My day job is with SonoPlot, Inc., where I am a co-founder and currently the Chief Technology Officer. We design and sell fluid dispensing systems that function on the microscale and are used in manufacturing microelectronics and for biological research. In my off hours, I do work on my personal software projects through Sunset Lake Software.

I was born and raised in a small north-central Wisconsin town called Waupaca. Adjacent to the town are a series of beautiful crystal-clear lakes that are impossible to tear yourself away from in the summer months. In my opinion, the best of them is Sunset Lake, where you can sit out on a pier and watch the sun go down in absolute silence.

I've been programming from an early age, ever since my parents brought home an Apple II+. In fact, I taught myself symbolic algebra just so I could read and write BASIC code. Mostly, it was just something I did for fun, but I started putting that skill to use when I worked part-time at the Waupaca Foundry during my high school and college years. More recently, I've programmed control or data capture systems for scientific equipment.

I am an engineer by training, with a B.S. in Chemical Engineering (and an area minor in Computer Science) from the Rose-Hulman Institute of Technology in Terre Haute, Indiana. I also have an M.S. and Ph.D. in Materials Science from the University of Wisconsin, here in Madison. My doctoral work focused on the use of controlled ultrasonics for microscale fluid dispensing, as well as cold plasmas and their application in chemically treating surfaces in an inexpensive and environmentally friendly manner. Listed below are my publications, all of which can be downloaded from this site.
