Welcome to the homepage of Frank Miller

I am Professor in Statistics at the University of Linköping where I work since 2022. Between 2013 and 2023, I was (Associate) Professor at the University of Stockholm. From 2003 to 2012, I applied and developed statistical methods in the pharmaceutical industry (at AstraZeneca in Södertälje, Sweden). I received my Ph.D. in 2002 from the University of Karlsruhe (Germany).

Currently, I am supervising the PhD student Karl Sigfrid as main supervisor. His research topic is: Design of computerized adaptive tests.

• From 2016 to 2021, I have supervised Renata Tsirpitzi. She successfully defended her PhD thesis Optimal design for dose-finding studies on December 17, 2021.
• During the same years, I have supervised Jonas Bjermo. He successfully defended his PhD thesis Test design for mean ability growth and optimal item calibration for achievement tests on December 10, 2021.
• From 2014 to 2019, I have supervised Mahmood Ul Hassan. He successfully defended his PhD thesis Achievement tests and optimal design for pretesting of questions on November 15, 2019.

I was co-supervisor for Oskar Gustafsson from 2015-2020. Pär Stockhammar was main supervisor; here the PhD thesis.
