Mikael Vejdemo-Johansson (pronounced like Michael Vey-demo Johansson).
As of the Fall semester, 2016, I am Assistant Professor of Data Science at the mathematics department of CUNY College of Staten Island.

If you are a student, please use Mikael.VejdemoJohansson@csi.cuny.edu. All other inquiries, please use mvj@math.csi.cuny.edu`. My office on CUNY College of Staten Island, Willowbrook campus, is 1S-208. I prefer contact by email over contact by telephone.
Research
My main area of interest is in applied algebraic topology and topological data analysis: how to compute the shape of a data set, and how to use that shape to understand the underlying data.
A large collection of lecture slides, written papers and other information can be found on my CV website.
I have helped create several software packages for persistent homology, most recently JavaPlex.
I am chair of the coordinating committee of the ATMCS conference series.
Among my many side projects is an enumeration of possible tieknots. To go with this paper, I wrote a webpage with a random tieknot generator.

Art
I have a simmering interest in mathematical art, especially using laser printers and other modern small-scale manufacture techniques.
I exhibited at the Joint Mathematics Meetings 2012.
I am helping to launch the Illustrating Mathematics community. Currently the best place to get to know us is at our wiki.
