This group The NCSA Genomics Group is a host for research into the use of high performance computing (HPC) for primary genomics analyses, such as alignment, variant calling, genome assembly, and RNASeq. By its nature, this research is highly collaborative. Every member of our team is affiliated with multiple departments or campus initiatives. The student participants in this group serve as a bond between the campus faculty using computational genomics analyses in their research, and the NCSA experts in HPC, storage, networking, databases, etc. Together we enable the use of advanced computing infrastructure in computational genomics. Explore this page to find out who is involved, how we are connected, and what projects are currently ongoing.

Staff members from the software directorate and other groups within research consulting are frequently collaborators on our projects.

Mutation profiles of cancer

Mr. Weber is developing machine learning methods to effectively stratify cancers

based on the statistical properties of mutations found in afflicted individuals.

Cancer stratification is predictive of disease outcomes, drug response and drug metabolism.

Effective computational approaches based on total data acquired to-date can make this process cheaper in the clinic.

Evolution of molecular networks and persistence of organisms

Construct and compare gene, metabolic and signaling networks from organisms across the tree of life.

The goal of the project is to provide support for the general framework of persistence strategies.

It postulates that persistence is achieved by biological systems via a tradeoff of traits that serve either economy, flexibility, or robustness. In this project we want to determine and quantify the molecular mechanisms that underlie these persistence strategies.

Will analysis of the biomolecular networks allow us to differentiate between organisms of differing economy, flexibility, and robustness, and subsequently classify unknown, newly discovered, or modified organisms within such predefined
classes?

Angelynn Huang

Angelynn contributed to benchmarking the performance and accuracy of Minimap2 (Li, 2018) -
a program used for analyzing sequencing read data in genomics.

Minimap2 maps the sequencing reads against the reference genome for the species.
Currently, BWA MEM (Li, 2013) is the most widely used tool for this purpose,
with Novoalign (Hercus and Albertyn, 2012) coming as a close second.
However, recent research (Li, 2018) suggests that Minimap2 is equally accurate yet also faster than BWA MEM.
Are these claims true? Can we validate them independently using our own measurements?
Sophia and Angelynn ran tests in AWS to answer these questions.
