Background

Andreas Briggert was born in Jönköping in 1984. In 2009 Andreas moved to Växjö and started to study at Linnaeus University. After receiving his Master of Science (M.Sc.) in Building Technology in 2014, Andreas started his PhD studies. During the spring of 2020 Andreas graduated as a PhD in Building Technology at Linnaeus University. Since July 2020 Andreas is employed as Assistant Professor at the Department of Construction Engineering and Lighting Science at Jönköping University and is a teacher in the course Structural Engineering 1.

Research activities

The purpose of Andreas research during his PhD studies was to investigate and suggests grading methods to improve the grading accuracy of machine strength graded structural timber and glulam lamellae to achieve a better material utilization of wood in load-bearing structures. Machine strength grading of sawn timber is a sawmill process in which density, modulus of elasticity and bending or tensile strength are predicted such that the timber can be assigned to strength classes. Andreas was during his years as a PhD student involved in several strength grading projects and has worked in close collaboration with both national and international sawmill companies.
