 Development of efficient data mining for biomarker discovery from high-dimensional genomic variant data is important for precision medicine and focuses on the use of information obtained from sequences such as whole exomes and whole genomes. Our work focuses on single nucleotide variants (SNVs) data obtained from genome-wide and whole exome data. This work is in collaboration with [[http://www.dbmi.pitt.edu/person/gregory-cooper-md-phd|Gregory F. Cooper]] and [[https://www.dept-med.pitt.edu/gi/faculty_info.aspx/Whitcomb5013/|David C. Whitcomb]] (at the University of Pittsburgh).
