Invitation to join an undergraduate research project

 Are you interested in participating in a research project? Do you just want to explore mathematics that hasn't been done already?
 My proposed project relates to both the Linear Algebra course I'm teaching in the fall and the Discrete Mathematics course I taught in Spring 2017.
 The objects you'll be playing with are called "arrangements" (or collections) of lines.
 I created a pair of Geometry and Topology Today videos discussing my mathematics for a general audience and for graduate students together with Scott Baldridge and David Shea Vela Vick. You can start by watching these videos and then emailing me to set up an appointment.


 Throughout his junior year and then as part of Vassar's Undergraduate Research Summer Institute (URSI) the summer before his senior year, undergraduate math major Baian Liu worked with me on topics related to this project.
 Our work together on arrangements of 11 lines will be on the arXiv this fall.
 He has presented a poster on his project at Summer Combo in Vermont and gave a 1015 minute talk at MAA's MathFest in Chicago. In the fall he will be presenting at the URSI symposium. Over winter break he plans to present a poster at the Joint Mathematics Meetings in San Diego.
 Baian will be applying to graduate school for Fall 2018.

Other useful information

 Math Horizons is the undergraduate publication of the Mathematical Association of America. Unlike research journals, Math Horizons publishes articles of interest to undergraduates without an extensive background in mathematics. Come to my office if you would like to look through a stack of older issues.
See my Math Horizons page to see some of my previous contributions and some ideas for undergraduate projects in knot theory.
 I am compiling a list of links on my Tips for Young Mathematicians page, with audiences ranging from undergraduates to graduate students to the general public.
