Brief biography

I'm a first generation college graduate from the University of Michigan.  I attended middle school and high school in a suburb of St. Louis after moving around a lot before that. I got interested in chemistry in high school where we did lots of cool stuff.  I can't say it was all that safe; lots of hydrogen sulfide in the room during the qual analysis we did and there was that ether fire when the separatory funnel with ether in it and a bunsen burner were sharing the same ring stand.  That one student did a pretty impressive leap to get out of the way.  Maybe that's where I first developed my interest in lab safety. 

My husband and I have 3 grown children, all doing very different things, one in Onalaska, one in Rochester and one in the Twin Cities.   And we now have a beautiful, active toddler granddaughter. 

We also have 2 cats and a few fish as well as a hobby farm northwest of Holmen with a good-sized garden.

Current courses at UWL

This semester I have one section of CHM 300 lab (Survey of Organic Chemistry), one section of CHM 305 (Organic Chemistry Laboratory) and one section of CHM 103 lab (First Semester Freshman Chemistry). 

I pretty much always teach CHM 305 but then the rest of my schedule may include some combination of 300, 103 or 104 labs.  I have been known to teach a lecture class or a CHM 100 lab if there is a need.

Teaching history

In graduate school at the University of Wisconsin-Madison I was a TA for an analytical lab and organic labs before I focused on research.

My next teaching opportunity was at the University of South Carolina at Aiken, a small school in the state of South Carolina system where I taught Organic Chemistry lectures and lab and an occasional freshman lab.  I also taught some courses in chemistry especially geared towards nursing students.  I was a tenured Associate Professor when we made the jump back to the midwest.

I started filling in here at UW-L as needed and have been full time since l996.  I was promoted to Senior Lecturer in 2009.

Professional history

I worked as a Research Assistant at Monsanto in St. Louis for a couple of summers during my undergrad years.  I was working on additives to the paper making process to increase its wet strength. 

After receiving my Ph.D. I was hired as a Research Chemist by Amoco Chemicals.  I worked for a year to help develop and modify a polymer that would have enough strength and thermal stability to be used in things like brake pads.  Like many Organic Chemistry graduates, I became a polymer chemist.  One time they sent me to do a polymer short course at the Mohonk Mountain House in upstate New York.  Pretty sweet.  And the money is great in industry.  We got a lot of restaurant meals, a color TV and a new truck before moving to Aiken and back into academia.

Since returning to academia at UW-L I have confined my research efforts to in-house work on new or modified organic and freshman chemistry lab experiments.  Lots of them.
