CONTRIBUTED PAPERS / PARTICIPATION AT PROFESSIONAL MEETINGS
In addition to the invited presentations and sessions organized, I have participated in many conferences in other
ways. Here is a summary of my conference participation since 1993.
 1992  2020, attended the annual MAA/AMS Joint Mathematics Meetings 23 times.
 1994  2020, attended the annual MAA MathFest (national summer meeting) 24 times.
 1993  2020, attended the twiceannual MAA Eastern Pennsylvania and Delaware section meeting too
many times to count (around 50).
 1993  2020, attended 21 other conferences and workshops, ranging from the International Conference
on Technology in College Mathematics to the annual meeting of the Pennsylvania Council of Teachers
of Mathematics.
 At these conferences I have presented 33 contributed papers and participated in over 20 workshops,
almost all of which were directly related to teaching and undergraduate mathematics.
