Title of Talk: Khovanov Homology: An undergraduate research project
Abstract: Khovanov homology is a sophisticated construction in knot theory, a branch of mathematics which is foreign and mysterious to many undergraduates. However, with only some linear algebra, some computer skills, and a little maturity as prerequisites, Khovanov homology can be used as a context to introduce many important mathematical ideas. I will discuss an on-going undergraduate research project whose goal is to compute the Khovanov homology of some families of knots. Such computations have only been performed for a handful of examples, thus our results will be of interest to researchers in the field. There will be many pictures and examples.

Title of Talk: Random Grid Diagrams
Abstract: This is joint work with undergraduate students Max Folkers, Eli Marriott, and Miguel Sanchez. We look at the distribution of the number of components in the population of knots and links represented by grid diagrams. We write programs in the R programming language to generate random samples of grid diagrams. We analyze the number of components and splittability of the links in these samples using statistical methods to gain a better understanding of the population of grid diagrams and the knots and links they represent.

Title of Talk: Fractals: A Basic Introduction
Abstract: We present a basic introduction to fractals by looking and understand the concept of Hausdorff dimension and Topological dimension by looking at simple examples of classic fractals and geometric constructs. We also define the Julia set and Mandelbrot set as an iterative function on the complex plane and present some examples together with some historical remarks.

Title of Talk: Prolongations on a Riemannian Manifold
Abstract: Traditionally the method of prolongations is carry out by algebraic manipulations which become very complex, especially in cases of partial differential equations on curved spaces, here we are applying some results from representation theory and differential operators to have a systematic method that allow us to close some overdetermined systems on a Riemannian manifold.

Title of Talk: Using Toilet Paper to Help Students Make Generalizations
Abstract: When students are given a specific problem to solve, they do not naturally create a general solution method that could be applied in other situations. In this presentation, I will discuss a project that I use to help students learn the value of generalization and give them an introduction to sensitivity testing. The project starts by having students find the number of sheets of paper on a specific sealed roll of toilet paper, but they must take that method and produce a formula that could find the number of sheets of paper on a general roll of perforated paper. They then test the various models created by the class for sensitivity to measurement error to find the

Title of Talk: Linear Algebra: When am I ever going to use this?
Abstract: I tell my students that linear algebra is the most useful mathematical subject they will take, and of course, they expect me to support that claim. In this talk I will discuss applications that I use in both Linear Algebra and Mathematical Modeling that require matrix operations. I will focus on the difference between a forward problem and an inverse problem. The subject areas will include games, historical geography, and ray-based tomography.

Title of Talk: Avoiding Paradoxes in Joker Poker
Abstract: If we add a Joker to an ordinary deck of cards, we'll find that the three-of-a-kind hands are more prevalent than the two-pair hands. (By convention, the Joker is always interpreted to make the hand's rank as high as possible.) Since the two-pair hands are rarer, by all rights they should outrank the threes-of-a-kind. But if the ranking is redone so that two-pair hands rank higher, then some of the Joker hands have to be interpreted as two-pair hands instead of threes-of-a-kind, and as a result the two-pair hands are again more prevalent than threes-of-a-kind. There is simply no consistent way to rank the poker hands in this Joker deck. It's enough to make Bret Maverick spin in his grave. \par What if we don't confine ourselves to the ordinary deck? Is it possible to find a deck that avoids paradoxes like the one above? Yes! Is it \emph{easy} to avoid paradoxes? Sure---if the deck is big enough. This talk will include the results of an investigation into this situation as well as a few details about the methodology. Only decks of size smaller than one million are considered; bigger decks become somewhat difficult to shuffle.

Title of Talk: Building a Model of the Effects of Multiple Myeloma on Kidney Function
Abstract: Multiple myeloma is a type of plasma cell cancer associated with many health challenges, including damage to the kidney. When a patient's kidneys are damaged, waste builds up in the bloodstream and the body begins to shut down. We would like to model what happens as the cancer affects the proximal tubule cells in the kidney, to eventually create a model that doctors can use as a predictive tool to catch problems early. We will explore an initial model that captures the biology of the interaction between kidney cells and proteins produced by the myeloma cells. The discussion will emphasize the development of the model using power law approximations in a system of ODEs.

Title of Talk: A System to Place Incoming Students in Computer Science, Mathematics and Statistics
Abstract: Joint work with Andrew Hirakawa and Russel Steinbach. Colleges utilize various methods of placing students, but many methods are time intensive, have limited scope, or lack precision. The placement system described here resolves many of these issues using a PHP based inference engine with extensively-researched rules. The system's placements compare favorably with those created manually by faculty, and students perform well in the system-recommended courses. Scripts store placements in a MySQL database and later generate individual LaTeX-based letter for each student. The scripts from this project run efficiently, follow established software-engineering principles, and are easily modifiable. The project automates every step of the process from loading student data into the database to generating individual letters for students.

Title of Talk: A Lab-based Pedagoy that Emphasizes Collaboration
Abstract: Following pedagogy pioneered by mathematician Eugene Herman at Grinnell College, this talk describes my experiences with a lab-based pedagogy in which students work collaboratively in pairs for each class session. As an instructor, I lecture about 4 hours per month, usually in 5-10 minute mini-lectures. Elements of this approach have been studied extensively by others to show effectiveness. Further, my own experience shows I can cover about 20% more material with this pedagogy over a traditional format, and test scores are better. Since this talk will focus upon pedagogy, the talk will largely be content-free.

Subject area(s): Course Syllabi and Online Materials
Title of Talk: Using a Database to Support a Course Home Page, Syllabus, Schedule, and Other Online Materials
Abstract: With static Web pages for a course, posting of daily readings, assignments, etc. requires either constant editing of pages or a search for materials relevant for each given day. Further, adjustments in time allocated for one topic likely requires manual changes in several days that follow. As a result, modifications in a course to accomodate student needs are labor intensive and consistency of schedules can be troublesome. Use of a database behind the scenes resolves many of these maintenance challenges. A student going to a course home page can view the assignments for the previous day, current day, and next day, together with a statement of the next course deadlines. Links to readings and assignments can be dynamic — automatically updated daily. Adjustments to course schedules can be made with the click of just a few buttons. Part of the talk will include a demonstration of a sample dynamic format for a current course. (Development of this type of course interface might make an interesting assignment for one or more computing students!)
