Biography


Dr. Brett Pickett is an Assistant Professor in the Microbiology and Molecular Biology Department. Before joining the faculty, he completed his B.S degree in Microbiology from BYU in 2005, his Ph.D. training in Microbiology at the University of Alabama at Birmingham, and his postdoctoral training in Pathology at the University of Texas Southwestern Medical Center at Dallas. He then obtained additional experience in industry, and at the J. Craig Venter Institute. He applies his past training to perform genome sequencing and comparative genomics analyses of human pathogens and cancers. He works to develop data mining workflows, apply machine learning techniques, and use advanced statistical workflows on the Fulton high-performance computing environment at BYU to better understand how human cells respond during infection acute infection or chronic disease (e.g. flu, Streptococcus, cancer, etc). The results from these analyses will then be used to generate hypotheses that can be tested in the wet lab. Dr. Pickett enjoys waterskiing, playing the piano, archery, and spending time with his wonderful wife Laura and their six children.

Research Interests


We are interested in learning more about how human pathogens cause infectious diseases. We do this through two separate but complementary approaches.

  1. We apply “big data” techniques on the high-performance computing environment at BYU to mine existing sequence information from public databases. Specifically, we look at how a human cell responds to disease by calculating how the messenger RNA (mRNA) changes when comparing disease and non-disease samples. We can then use this information to determine the functions and signals that are changed during and after infection or disease.
  2. We perform comparative genomics analyses of viruses and bacteria to better understand how, why, and where they accumulate mutations in their genomes. We also apply statistical methods to determine how these mutations affect the phenotype of the pathogen.
