Jesper Rydén

Jesper Rydén
I am a senior lecturer in Biometry.


Main duties: research in biometry (i.e. the application of mathematics and statistics to problems in the agricultural, environmental, and biological sciences); statistical consulting; teaching at various levels.

Director of studies for courses at the unit Applied statistics and mathematics.


The academic year 2022-2023:

MS0073, Basic mathematical statistics

I have a broad experience of teaching courses in applied statistics, in particular from Uppsala University, e.g. courses in time-series analysis, random processes, regression and analysis of variance, generalised linear models, statistical risk analysis.


Regression models for count data; extreme-value analysis with applications in the earth and engineering sciences. 


2022- : Member of editorial board, Musicae Scientiae.

2019-2021: Secretary in Cramérsällskapet, a division within Swedish Statistical Society.

2018-2019: Collaboration with Pearson Education Ltd as external subject expert.
