1.
Aberasturi D, Piegorsch W, Bedrick E, Lussier Y
Stat (Int Stat Inst) . 2023 Oct; 12(1). PMID: 37885703
We describe a collaborative project involving faculty and students in a university bioinformatics/biostatistics center. The project focuses on identification of differentially expressed gene sets ("pathways") in subjects expressing a disease...

Liu J, Piegorsch W, Schissler A, McCaster R, Cutter S
J Appl Stat . 2022 Jun; 49(9):2349-2369. PMID: 35755089
We develop and study a quantitative, interdisciplinary strategy for conducting statistical risk analyses within the 'benchmark risk' paradigm of contemporary risk assessment when potential autocorrelation exists among sample units. We...

Sans-Fuentes M, Piegorsch W
Environmetrics . 2021 Aug; 32(5). PMID: 34354387
Benchmark analysis is a general risk estimation strategy for identifying the benchmark dose (BMD) past which the risk of exhibiting an adverse environmental response exceeds a fixed, target value of...

Aberasturi D, Pouladi N, Zaim S, Kenost C, Berghout J, Piegorsch W, et al.
Bioinformatics . 2021 Jul; 37(Suppl_1):i67-i75. PMID: 34252934
Motivation: Identifying altered transcripts between very small human cohorts is particularly challenging and is compounded by the low accrual rate of human subjects in rare diseases or sub-stratified common disorders....

Wheeler M, Piegorsch W, Bailer A
Risk Anal . 2018 Oct; 39(3):616-629. PMID: 30368842
Quantitative risk assessments for physical, chemical, biological, occupational, or environmental agents rely on scientific studies to support their conclusions. These studies often include relatively few observations, and, as a result,...

Liu J, Piegorsch W, Schissler A, Cutter S
J R Stat Soc Ser A Stat Soc . 2018 Jun; 181(3):803-823. PMID: 29904240
We develop a quantitative methodology to characterize vulnerability among 132 U.S. urban centers ('cities') to terrorist events, applying a place-based vulnerability index to a database of terrorist incidents and related...

Schissler A, Piegorsch W, Lussier Y
Stat Methods Med Res . 2017 May; 27(12):3797-3813. PMID: 28552011
Modern precision medicine increasingly relies on molecular data analytics, wherein development of interpretable single-subject ("N-of-1") signals is a challenging goal. A previously developed global framework, N-of-1- pathways, employs single-subject gene...

Schissler A, Li Q, Chen J, Kenost C, Achour I, Billheimer D, et al.
Bioinformatics . 2016 Jun; 32(12):i80-i89. PMID: 27307648
Motivation: As 'omics' biotechnologies accelerate the capability to contrast a myriad of molecular measurements from a single cell, they also exacerbate current analytical limitations for detecting meaningful single-cell dysregulations. Moreover,...
