Why Math?
  • Mathematics is fundamentally entrenched in the
    world
  • It is integral to many different disciplines
  • Advanced math is becoming more relevant to
    todays society

High School Topics

Fractals
Fractals
- geometrical figures that are generated by
starting with a very simple pattern that
grows through the application of a set of rules
,
Mandelbrot's fractal geometry provides a
mathematical model for many complex forms found
in nature such as shapes of coast lines,
mountains, galaxy clusters, and clouds. Here,
both the trees and the clouds are actual fractals

Maths in Real Life
  • Fundamental notion in CS Algorithm
  • What is an Algorithm?
  • Informally a recipe for computing something
  • Formally a finite sequence of instructions for
    correctly solving a computational or mathematical
    problem in a finite amount of time
  • Examples of algorithms
  • Numerical Finding the GCD of two numbers
  • Semi-numerical Sorting a deck of cards
  • Linguistic Checking and correcting the grammar
    of a text
  • Specialized -Rendering a space ninja in a video
    game -Optimizing the price
    of a stock option

10
Maths in Real Life
  • OK, so wheres the math?
  • Algorithms are described in terms of mathematical
    and logical instructions
  • Math helps you analyze (and hopefully improve!)
    the running time of your algorithms
  • Where do we need fast algorithms?
  • Graphics and Games
  • E-Commerce
  • Aerospace
  • Energy

Optimal Pricing
  • Question Why did the person sitting next to you
    in an airplane pay a different price for her
    seat?
  • Answer Because airlines apply methodologies
    known as Revenue Management and Pricing
    Optimization

16
Optimal Pricing
  • The problem Selling the right product to the
    right customer at the right price and the right
    moment
  • Used in industries with
  • Limited capacity
  • Perishable inventory
  • High fixed costs and low marginal costs
  • That includes airlines, telecoms, rail, car
    rental, hotels, etc

17
Optimal Pricing
  • Sub-problems and research areas
  • Demand estimation (statistics)
  • Customer behaviour modelling (econometrics)
  • Capacity management (operations research)
  • Price and revenue optimization (operations
    research)
  • Research perspectives
  • Still an open field, no definitive solution yet
  • Lots of interest from the industry (funding!)

22
Alejandro Garcia
  • Favourite thing about my job The learning
    environment and the emphasis on research.
  • Most Important educational skills Economic
    intuition, from my degree in Economics.
    Computations skills to help me program models,
    linear algebra for econometric analysis and
    calculus to help me understand the solution
    techniques that are used in the types of models
    that my group works with.

23
How do I further my education?
  • While youre an undergrad
  • Workshops
  • Seminars
  • Research collaborations (Summer internships)
  • Graduate Studies

24
What can I do after?
  • Many Future Options
  • Teaching
  • Pure Research
  • Applied Research
  • Implementation (taking applied research and
    getting it to work in real situations)

Mathematicians are everywhere!
