started her career studying problems in transonic fluid flow, using
asymptotic models she learned from her Ph.D. adviser, Cathleen Morawetz. That early
work from her dissertation improved the available
estimates for drag on an airfoil in the presence of weak shocks. The
work involved computational models and theoretical work on the
well-posedness of the Tricomi problems that arose in the mapping
Dr. Ipina is best known for her work in Math Education. Her early participation in the national debate Calculus, especially as it involves writing and appropriate uses of technology, evolved into an interest in graphical representation. She and Gilda Palis used APOS models on classroom research and curriculum design.
The last five years she has focussed almost exclusively on the middle level teacher. She is one of the co-PIs on the NSF grant that launched UW's Master Program, and Endorsement Program for in-service middle level teachers.
