# Glenn Ledder

I am now a self-funded postdoc (ie, an emeritus professor) and have moved to Denver Colorado. I check email regularly and am still active in scholarship.

Feel free to use any of my materials for courses at other schools. I would
appreciate being informed about which of my materials have been used where.

## Supplementary Materials for *Mathematical Modeling for Epidemiology and Ecology*

My new book, *Mathematical Modeling for Epidemiology and Ecology*, was published by Springer-Verlag in April 2023. Supplementary materials include programs and data files.

## Other BioMath Educational Resources

My BioMath educational resources include books, book chapters, pedagogical papers, and teaching modules.

## Course Notes (for standard math courses)

These include stand-alone notes for topics in calculus, partial differential equations, asymptotics, and nonlinear optimization, and a full set of notes for queueing theory.

## Projects (for standard math courses)

These include projects for various applied math courses.

## Talks

I have given a large number of expository and pedagogical talks. I've also posted some recent research talks in mathematical biology.

## Research Papers

My research work has been in mathematical ecology, population dynamics, epidemiology, plant physiology, and plant life history theory.

## BUGBOX Mathematical Modeling Simulations

BUGBOX software is designed for inquiry-based learning of mathematical modeling for population dynamics. The software creates a virtual laboratory space inhabited by virtual insects. Students conduct experiments and devise mathematical models to predict the experiment results.

In **BUGBOX_predator**, students do experiments to find a relationship between prey density and consumption by one predator.

In **BUGBOX_population**, students observe the changes in the insect population to discover aspects of the insects' life cycle. They can construct a simple linear difference equation model, using their observations to estimate the parameter values. Four different scenarios give a sequence of increasing complexity.

## Large Print macros for LaTeX

It is somewhat tricky to produce a large print version of a LaTeX document for visually-impaired students. I have worked out a general scheme that allows me to quickly convert documents to large print.
