Hello!  My name is Heidi Berger and I have been at Simpson since 2008.  I think that the field of mathematics is drop-dead gorgeous and I absolutely love teaching it.

My research area lies in differential equations, difference equations, and time scales calculus.  Since my arrival at Simpson, I have collaborated with Dr. Clint Meyer on several projects that apply differential equations to questions of population ecology and restoration biology.  This work has been with a monotonically increasing number of undergraduates through the generous support of the Dr. Albert H. & Greta A. Bryan Summer Research Program, the Iowa Academy of Science, the Center for Undergraduate Research in Mathematics (CURM), and the National Research Experience for Undergraduates Program (NREUP).

Additionally, I am the advisor to the Differential Analyzer Club.  A differential analyzer is a precursor to the modern computer.  In 2010, two Simpson undergraduates built a differential analyzer that can be used for research as well as educational outreach to high schools, science museums, and colleges.  This work has been done in conjunction with Dr. Bonita Lawrence and her team at Marshall University in West Virginia.  If you ever want to see the differential analyzer in action, stop by my office in Carver 332!

In my spare time, I enjoy spending time with my family, traveling, cooking, and playing card games.  I am also a sloth enthusiast.
