Mikael Vejdemo-JohanssonDivision of Science and Technology - Mathematics
Dr. Mikael Vejdemo-Johansson worked on computational homological algebra for his MSc at Stockholm University and his Doctrate from the Friedrich-Schiller University in Jena. Since then he has worked in Topological Data Analysis, with postdoctoral positions at Stanford, University of St Andrews, KTH Royal Institute of Technology and as a long-term visitor at the Institute for Mathematics and its Applications. His main area of interest is in applying abstract algebra and topology to data: analyzing the shape and connectivity features of data sets using algebraic topology. When not working with this, he pursues a wildly varied spectrum of interest: recent work includes the enumeration of necktie knots (266 682 in total), and using laser cutters and 3d printers to produce mathematical art.
