I received Ph.D. (2000) and M.S. (1998) degrees in Statistics from U.C. Davis, an M.A. in Mathematics from the University of New Mexico (1996), and a B.S. in Mathematics from the University of Minnesota (1992). Before joining the University of South Carolina Department of Statistics in 2010, I was an associate professor in the University of Minnesota Division of Biostatistics 2005-2010, and an assistant professor at the University of New Mexico Department of Mathematics and Statistics 2000-2005.

Recent projects involve spatial modeling through frailties and copulas, ordinal data models, and Bernstein polynomials. My research interests over the last 15 years broadly include survival analysis, Bayesian nonparametric priors, and diagnostic screening. Publications. Full curriculum vitae.

My past Ph.D. students are Junshu Bao (2016), William Cipolli (2016), Haiming Zhou (2015), Li Li (2014), Yuhui Chen (2012), Luping Zhao (2008), Mingan Yang (2006), and Ling Xu (2005).

Talk on spatial frailty survival models at Northern Illinois University (March 2017). An earlier version was given at the University of Arizona at Tucson (December, 2016).

Talk on survival analysis via spatial copulas at the University of Michigan Department of Biostatistics (March 2016). Earlier versions were given at the University of Alabama Dept. Mathematics, (April 2015) and the Medical School of Wisconsin (June 2014).

Talk on DPOAE test-retest differences given at Northern Illinois University (March 2017). Versions were also given at the I.S.B.A. meeting in Sardinia, Italy (June 2016), J.S.M. in Chicago (August 2016), the University of New Mexico Dept. Mathematics and Statistics (March 2016), Wake Forest University Dept. Biostatistical Sciences (March 2016), University of South Carolina Dept. Epidemiology and Biostatistics (Feb. 2016) and University Texas El Paso Dept. Mathematical Sciences (Feb. 2016).

I enjoy writing short, simple piano tunes; here's Christmas Seasoning and Didacts and Carpets recorded December 2016. Time for bed and Roasted Stoat were recorded in 2015. Here's two recorded June of 2014: March of the Otters and Beefsquatch Interlude.

Here's some older tunes: Diablo IPA, Jinx, Getting Tenure, Folding Chair, Geraldine, Bear, Eelpout Stout, Ulf, What is This?, Piano 3, Sax Panther, Find the Fish, The Doctor and the Pencil, Realization, Cheese and Krakens.

I also play bass in the cover band Gas Money. We are available for weddings, funerals, Revolutionary War battle re-enactments, bat mitzvahs (not bar mitzvahs), minor political office inaugerations, the grand opening of strip malls, pool parties, and the burning of our anthropological ancestors, e.g. Lucy, in effigy.
