Bioinformatics (IM3) 
Org: Miklos Csuros (University of Montreal) 
The minisymposium addresses current problems in
the mathematics of molecular sequence analysis.
Advanced technologies for sequencing DNA and
proteins drive increasingly more comprehensive
studies about the diversity of molecular sequences
across living organisms. Talks in this
minisymposium touch on fundamental mathematical
and algorithmic issues arising at different stages
along the analysis pipeline between sequence data
production and their biological applications.

Combinatorial Optimization (IM1) 
Org: Mohit Singh (McGill University) 
Combinatorial optimization problems usually come in two flavours, ones that
can be solved in polynomial time and others that are NPhard. This session
will feature recent developments on problems from both classes. For the
former, the talks will present fast algorithms for some fundamental
combinatorial optimization problems. For the problems that are NPhard, the
talks will present approximation algorithms that are efficient and solve the
problem approximately with a good guarantee on the solution.

Computational Complexity (IM7) 
Org: Venkatesh Srinivasan (University of Victoria) 
Computational complexity is a central field of research in theoretical
computer science that focuses on classifying computational problems
based on the amount of resources they require. Examples of such
resources include time, space, communication, amount of randomness and
so on. This field has introduced many interesting computational models
to study such problems and has been the source of amazing results in the
recent years leading to a deeper understanding of the power and
limitations of efficient computation.

Cryptography (IM2) 
Org: Bruce Kapron (University of Victoria) 
There are a now a variety of wellfounded mathematical approaches to
understanding security in cryptographic systems. Techniques from algorithms and
computational complexity, formal logic, and information theory have all been
successfully used in providing a more rigorous foundation for the study of cryptography. This minisymposium will explore cryptographic security from these varied perspectives.

Extremal Graph Theory (IM4) 
Org: Penny Haxell (University of Waterloo) 
Extremal graph theory can be described as the study of how global
properties of a graph can guarantee the existence of local substructures.
A classical example is the theorem of Turán, which tells us the
maximum number of edges that a graph with $n$ vertices can have, if it
does not contain a complete subgraph with $r$ vertices. Many natural
questions can be formulated as extremal graph problems, and the subject
has developed into a rich
theory. Applications abound in many fields, including number theory,
optimization, theoretical computer science, economics, hardware
design, and optical networks.

Probabilistic Combinatorics (IM5) 
Org: Tom Bohman and PoShen Loh (Carnegie Mellon University) 
Probabilistic Combinatorics stands at the intersection of several
thriving areas of Mathematics and Computer Science. It focuses on the
combinatorial properties of random discrete objects (e.g., random
graphs), and their potential applications to other branches of
Mathematics. This minisymposium will highlight a variety of recent
advances in the field. We also intend to use this forum to make state
of the art probabilistic techniques available to a broader audience.
