                color="#ff0000"><font color="#000000"> Knotoids were
                  introduced by Turaev as open-ended knot-type diagrams
                  that generalize knots. Turaev defined a two-variable
                  polynomial invariant of knotoids generalizing the
                  Jones knot polynomial to knotoids. We will give a
                  construction of a triply-graded homological invariant
                  of knotoids categorifying the Turaev polynomial,
                  called the winding homology. Forgetting one of the
                  three gradings gives a generalization of the Khovanov
                  knot homology to knotoids. We will briefly review the
                  basics of the theory of knotoids and also explain the
                  notion of categorification which plays an important
                  role in contemporary knot theory -- no prior knowledge
                  will be assumed.<i><br>
