I am Andres Aravena

  • Assistant Professor at Molecular Biology and Genomics Department
  • Mathematical Engineer, U. of Chile
  • PhD Informatics, U Rennes 1, France
  • PhD Mathematical Modeling, U. of Chile
  • not a Biologist
  • but an Applied Mathematician who can speak “biologist language”

I come from Chile




Small country of 17 million people

Spanish colony 500 years ago (so language is Spanish)

Independent Republic 200 years ago

First Latin American country to recognize Turkish republic

Everyday life very similar to Turkey

Chileans like Turkish soap operas


Latin America in Turkey

Foreigners enrich the hosting countries. Just look at the food:

  • Corn is from North and South America: maiz
  • Tomato is Mexican: tomates
  • Potato is from Chile and Peru: patatas

Diversity increases opportunities

Why computers?

for Science and beyond

Computers are rule changers

Modern computers were created to solve math equations

Then they were used to handle big databases

They became cheap and found everywhere

They became communication tools

They transformed society and science

How many computers do you use?

  • Cellphone
  • TV
  • Cable decoder
  • Microwave oven
  • Washing machine
  • Car motor
  • Metro
  • Elevator
  • Notebook

Computers transformed

  • The banking industry
  • The air travel industry
  • The manufacturing
  • The cars
  • The movies
  • Science

Four Paradigms of Science

1 Empiric

  • Observation of isolated facts
  • Description of relationships
  • e.g. Botany, naming stars

2 Theoretical

  • Abstract models and theories
  • Usually expressed in mathematical formulas
  • Correct predictions validate the models
  • e.g. Mendel’s laws of inheritance, Newton’s law of Gravity

Four Paradigms of Science

3 Simulation Based

  • Models that cannot be expressed in formulas
  • Formulas that cannot be solved
  • e.g. Protein structure prediction, three body problem, galaxy modelling

4 Data Based

  • Discovering patterns hidden in data
  • Huge volumes of data
  • Complex interactions
  • e.g. Bioinformatics, Astroinformatics, Data mining
