Peter F. Thall’s Personal Website
Here is a
picture of me being a biostatistician, with a pen, a pad, a computer, and
everything. This is what “science” looks like in real life.
Below is a picture
of me in my youth, before all the wear-and-tear reduced me to my present
website seems to require a list of hobbies. In keeping with this dubious
convention, here are some of mine:
trading Apple stock options; nonverbal canine communication; aggressively
practicing humility; intergalactic exploration; watching nearly every movie
ever made; gourmet cooking; giving terribly useful advice to people who seem to
need it; staying in hotels in cities I probably wouldn’t visit if I weren’t
attending a conference; collecting

New Book on Dose Finding Trials
Bayesian Designs for Phase I-II
Yuan, Nguyen, and Thall. Chapman & Hall/CRC Biostatistics Series,
Unbiased Review: This book is a “must own” for
absolutely everyone involved in clinical trials. It is chock-full of deep wisdom, astonishing
insights, and innovative clinical trial designs. It certainly would make a
great birthday or holiday present, and would look impressive on your bookshelf
or coffee table. You probably should buy
at least two copies, in case your dog decides to see what it tastes like and
chews it up, or one of your colleagues borrows it and never returns it.
If you want
to read some of my publications, click on the links below. All of them are about statistics, medicine,
or clinical trials, and most are astonishingly well written. If you like one of them, be sure to tell your
friends and relatives about it.
