1. Algebraic topology

Algebraic topology is a branch of mathematics that studies the topological properties of spaces using algebraic tools. It is closely related to geometric group theory, which studies the properties of groups using geometric techniques.

• Homology
  

  Homology is a fundamental concept in algebraic topology that measures the number of holes in a space. It is used to classify spaces and to study their topological properties.

• Cohomology
  

  Cohomology is a generalization of homology that is used to study the cohomology groups of a space. Cohomology groups are used to classify spaces and to study their topological properties.

• Fundamental group
  

  The fundamental group of a space is a group that encodes the fundamental properties of the space. It is used to classify spaces and to study their topological properties.

• Knot theory
  

  Knot theory is a branch of algebraic topology that studies knots, which are closed curves in 3-space. Knot theory is used to study the topological properties of knots and to classify them.

Lia Lin is a leading researcher in algebraic topology. She has made significant contributions to the field, including developing new techniques for studying the homology and cohomology of spaces. Her work has applications in a variety of areas, including knot theory and geometric group theory.

2. Geometric group theory

Geometric group theory is a branch of mathematics that studies the interplay between group theory and geometry. It is closely related to algebraic topology, which studies the topological properties of spaces using algebraic tools.

• Cayley graphs
  

  A Cayley graph is a graph that represents a group. The vertices of the graph are the elements of the group, and the edges of the graph are the products of the elements of the group.

• Hyperbolic groups
  

  A hyperbolic group is a group that has a Cayley graph that is hyperbolic. Hyperbolic Cayley graphs are characterized by their negative curvature, which means that they have a lot of "wiggle room" and are not very rigid.

• Mapping class groups
  

  A mapping class group is a group that consists of all the homeomorphisms of a surface. Homeomorphisms are continuous bijections that preserve the topology of the surface.

• Geometric invariants
  

  Geometric invariants are properties of groups that can be expressed in terms of their geometry. For example, the Gromov boundary of a group is a geometric invariant that measures the "size" of the group.

Lia Lin is a leading researcher in geometric group theory. She has made significant contributions to the field, including developing new techniques for studying the geometry of groups. Her work has applications in a variety of areas, including algebraic topology and knot theory.

3. MacArthur Fellowship

The MacArthur Fellowship is a prestigious award given to individuals who have shown exceptional creativity and promise in their fields. It is often referred to as the "genius grant" because it provides recipients with a no-strings-attached grant of $625,000 over five years. Lia Lin was awarded a MacArthur Fellowship in 2014.

Lin's MacArthur Fellowship recognized her groundbreaking work in algebraic topology and geometric group theory. Her research has led to new insights into the structure of spaces and groups, and has applications in a variety of fields, including knot theory and computer science.

The MacArthur Fellowship has allowed Lin to continue her research and to pursue new projects. She has used her fellowship to fund a variety of projects, including a collaboration with artists to create works of art that are inspired by her research.

The MacArthur Fellowship is a significant recognition of Lin's achievements as a mathematician. It is also a testament to her potential to continue making significant contributions to her field.
