3. The Problem of Big Data in Biology

4. 4 The Problem of Big Data Volume Velocity of process Variability

5. Motivation Recent developments in biotechnology have allowed the high-throughput data generation from biological samples We have lots and lots of data about all aspects of biology (although still mostly about humans) How can we make sense of all this data? – Analyse the data to extract new knowledge about the biology  Data Mining

6. 1973 Sharp, Sambrook, Sugden Gel Electrophoresis Chamber, $250 1958 Matt Meselson & Ultracentrifuge, $500,000 The Problem of Big Data in Biology hopefully comfortable enough to minimize the technology and focus on the biology.

12. A Super-Moore’s Law

13. So what data can we generate? Biological data can be generated at many different levels – Genomics (DNA) – Transcriptomics (RNA) – Proteomics (proteins) – Metabolomics (small compounds) – Lipidomics (lipids) Hundreds of –omics have been catalogued Hundreds

14. The Problem of Big Data in Biology High Throughput Phenotyping The large amount of sequence based data need balancing with equally powerful phenotypic data. Phytomorph Project (Univ. Wisconsin) $70K for 30 cameras 200 movies of root growth 4GB/day of images for processing

19. General Types of “….Informatics techniques…..” Databases – Building, Querying – Object DB Text String Comparison – Text Search – 1D Alignment – Significance Statistics Finding Patterns – AI / Machine Learning – Clustering – Datamining Geometry –Robotics –Graphics (Surfaces, Volumes) –Comparison and 3D Matching (Vision, recognition) Physical Simulation –Newtonian Mechanics –Electrostatics –Numerical Algorithms –Simulation

20. Algorithmic vs. Statistical Perspectives Computer Scientists Data: are a record of everything that happened. Goal: process the data by positing a model to find interesting patterns and associations. Methodology: Develop approximation algorithms under different models of data access since the goal is typically computationally hard. Statisticians (and Natural Scientists) Data: are a particular random instantiation of an underlying process describing unobserved patterns in the world. Goal: is to extract information about the world from noisy data. Methodology: Make inferences (perhaps about unseen events) by positing a model that describes the random variability of the data around the deterministic or stochastic model.

21. Major Application : Finding Homologs

22. Major Application : Designing Drugs Understanding How Structures Bind Other Molecules (Function) Designing Inhibitors Docking, Structure Modeling (From left to right, figures adapted from Olsen Group Docking Page at Scripps, Dyson NMR Group Web page at Scripps, and from Computational Chemistry Page at Cornell Theory Center).

24. Big changes in the past... and future Consider the creation of: Modern Physics Management Science Computer Science Transistors and Microelectronics Molecular Biology Biotechnology These were driven by new measurement techniques and technological advances, but they led to: big new (academic and applied) questions new perspectives on the world lots of downstream applications We are in the middle of a similarly big shift!
