Industry Talk: Tales from the Frontier of Genomics

22nd Mar 2019 2:10pm-3:00pm
Presenter/Speaker: Dr Sean Irvine, Real Time Genomics
Location: G.1.15

In this talk, Sean will give some background on past projects he has been involved with, leading up to his current work in DNA sequence analysis at Real Time Genomics.  The main part of the discussion will concern the challenges in processing human DNA sequence data.  In particular, the talk will step through the computational steps involved in taking the output of a genomic sequencing machine through to generating outputs suitable for clinical interpretation.  These steps include the mapping of sequence data to a reference human genome, the identification of germline and somatic variants in a sample, and clinical interpretation.  Current problems in genomics including evaluation and bench-marking of results, dealing with pedigrees, and the detection of copy number and structural variants will be mentioned.  Lessons learned and success stories from dealing with data from real customers will be presented.  Time permitting, a brief introduction to metagenomic analysis and strain detection will be given.  The talk will concentrate on computational aspects of dealing with large datasets and accurately determining variants in individual samples including the ranking of variants using a machine learning approach.  There will be some discussion of the best practice software engineering techniques used by Real Time Genomics.  In particular, the continuous integration environment, testing framework, and Jumble system for measuring code and test quality in Java will be shown.  Brief mentions of projects involving entity extraction and text classification, leading to SureChEMBL system for identification of chemicals in patent documents.  Only a minimal knowledge of genomics will be assumed.
