About Me:

I will be joining the LSU Health Science Center this fall as an Assistant Professor in Biostatistics. I received my Ph.D. in statistics from Rice university in May 2018. During my time at Rice, I worked with Peter Thall from the M.D.Anderson Cancer Center Biostatistics department.



My particular interests include: Clinical Trials, Bayesian Methods, Survival Analysis, Variable Selection, Categorical Data, Econometrics, and Teaching. I hope to improve on existing clinical trial methodology and use Bayesian methods for economic data to improve policy decisions.


I’m from Baton Rouge, graduated from LSU (Geaux Tigers) and spent four years in the great city of Houston, eating at over 100 different restaurants while there. I’m a huge Saints and Lebron James fan. My girlfriend Whitney and I have two cats – Zeus, totaling 24 pounds and his much smaller brother Beta (\beta). I absolutely love statistics and am grateful to be in such a fantastic and diverse field.
