The working group on Material Flow Management at the Chair of Wood Science offers a master’s thesis with a methodological focus on wood-related LCA studies. We are searching for an interested candidate to conduct parameter studies to analyze the influence of inherent wood properties like density, moisture or biogenic carbon on the results of LCA studies.. The Master's Thesis is closely related to the current research project "Hardwood utilization in the scope of an efficient bioeconomy" (LauBiOek). The Master's student will also gain direct insights into the LauBiOek research project:

Goal and objectives

  • Identification of relevant, inherent wood properties on the level of different tree species as well as property differences between softwoods and hardwoods that may influence the LCA results and should thus be considered
  • Literature review on the consideration of the identified parameters in LCA studies on wood-based products
  • Definition and modelling of LCA systems for different wood products (mass timber products, derived timber products) using openLCA software
  • Parameter analysis using the LCA system to determine the influence of the identified wood properties on the LCA results
  • Development of recommendations for the consideration of specific wood properties in future LCA studies


  • Basic knowledge about wooden resources and/or life cycle assessment
  • Interest in modelling
  • Working in a team

Material Science and Engineering

Wood Technology

Wood is a widely used construction material due to its renewable nature and favorable mechanical properties. However, its thermal behavior under high temperatures, especially during fire incidents, remains a critical aspect that requires comprehensive investigation [1, 2]. This master thesis aims to study the temperature-dependent material properties of wood under elevated temperatures. By subjecting wood samples to various temperature ranges, a deeper understanding can be obtained about moisture evaporation rate in the samples and their density loss. This thesis will contain two main parts, including experimental fire tests and CT-scanning of the samples . From the CT-scanned samples, models will be developed to link the dry density of the material to the stiffness properties. In addition, algorithms will be developed to distinguish between the dry and the wet density of the wood. Figure 1 depicts a previous study involving experimental testing, analysis, and simulation of the charring rate of Laminated Veneer Lumber (LVL) panels [3].


  • Conduct a comprehensive literature review to gather existing knowledge on the thermal properties of wood and its behavior under different temperature ranges.
  • Understand the CT scanning concept and the possibilities to distinguish between the dry and the wet densities.
  • Design and set up controlled experiments to subject wood samples to different temperature ranges.
  • Perform CT scans on the wood samples after different temperature ranges to visualize internal material changes
  • Analyze the CT scan data to quantify density loss and density variation within the wood samples due to thermal exposure.
  • Come up with an approach to distinguish between the dry and the wet wood densities from the CT scans, and to assign correct material properties based on the density values.

We offer:

  • Thesis in the area that is highly demanded for further industrial development.
  • Equipped workspace during the thesis period.
  • Supervision and support during the thesis.
  • Access to different systems required for the work.
  • Opportunity to publish a research paper.

Wood is a natural fiber-based material with anisotropic and non-homogenous material properties. To better describe specific material properties of a wooden board, its fiber pattern as well as knots need to be considered. Stresses are concentrating on the location of knots and thus influence considerably the strength properties as well as the damage mechanism (initiation and propagation path) of wood. Therefore, in this Bachelorthesis, the bond, density and stiffness of knots needs to be investigated experimentally. A test setup will be developed for extracting specific material properties of knots.


  • Literature review (knot properties, knot classification, embedding into the surrounding clear wood)
  • Preparation of test specimens and arrangement of the test setup
  • Planning and conducting experiments to determine the load-bearing capacities of knots and their stiffness properties
  • Evaluation of experimental data

Language: English or German

Bachelor thesis available from August 2022

Beech (fagus sylvatica) stock in German forests is increasing [1] while the use of beech wood for construction purposes is not popular yet. Beech glued laminated timber offers high compression strength and stiffness which makes it favourable to be used in load bearing columns. Beside possible material failure due to increase in stresses, these columns may face stability issues, such as buckling as well.


Buckling behaviour of columns can be studied and be modelled by means of Finite Element method. Finite element models, in general need to be validated for their extended use in application. Experimental testing of the buckling behaviour of beech glulam columns has been performed at Holzforschung München without considering structural imperfections in single layers [2]. However, the dynamic material properties of the applied lamellas in the beech glulam are available. Dynamic properties of these lamellas exhibit a correlation with strength and stiffness properties [3]. It was also shown that material heterogeneities and imperfections are influencing the strength properties of beech lamellas. Therefore, after studying the influence of these lamella imperfections on stability of the glulam and by further developing the method for modelling of buckling, setups need to be suggested for glulam beams based on the available dynamic properties of single lamellas in this thesis. In the end, some experimental testing on beech glulam columns will be performed where dynamic properties as well as locations and sizes of the knots in the single layers are known.

Tasks of the thesis are:

  • Studying of orthotropic and heterogeneous behaviour of wood and its influence on stability problems.
  • Suggesting setups for beech glulam, based on the available strength and stiffness properties of single lamellas from tension tests.
  • Further developing the provided approach for simulation of buckling behaviour.
  • Performing small set of experiments on beech glulam columns (where the information about imperfections in single lamellas are known) for validation of the model.

Required knowledge:

  • Background in modelling and simulations

The load carrying capacity of beech glued laminated timber is regulated in the general technical approval Z-9.1-679:2014. The strength and stiffness of a member depends on the sorting class of the employed lamellas. A research project at Holzforschung München showed that beech glulam members partially manufactured from low quality beech lamellas achieve high compression and tension strength. The members in the research project were built up from lamellas specifically arranged by their dynamic Modulus of Elasticity. In practical application, the lamellas are sorted into strength classes and glulam members are constructed with randomly chosen lamellas from the sorting class. Tension and compression tests should be performed in this work in order to transform the results of the scientifically built up beech glulam members to stochastically arranged beech glulam members.

Goals and tasks

  • Familiarisation with the relevant literature
  • Performance of compression and tensile tests on beech glulam beams
  • Evaluation of the test results

The results of the work are to be presented in an approx. 30-minute lecture at the Wood Science Seminar of the Wood Research Munich.

We (Benz lab, Gagneur lab) are looking for a motivated student of biology/molecular biotechnology/bioprocess engineering/biochemistry to assist in developing and carrying out a large, multi-species investigation of regulatory genomics.

The Project

Deciphering the impact of variation in non-coding regulatory regions of the genome on gene expression is a central challenge in genetics. This goal has not been achieved for any organism but important progress has been made by leveraging genome-wide omics datasets (RNA-Seq, ChIP-Seq, ATAC-Seq and quantitative proteomics, see e.g. [1]) and artificial intelligence, particularly deep learning ([2–4], see [5] for a review). A key challenge, however, is the limited amount of available sequence data with high variation, as most omics experiments are done in the same few model organisms. As such, deep learning models are only aware of a tiny fraction of the vast space of possible gene regulatory sequences.

We propose to move beyond these limitations by collecting genome-wide multi-omics data (RNA-Seq, ATAC-Seq and Mass-spectrometry based proteomics) from diverse fungal species in a variety of growth conditions. Based on these experiments, we will train a deep learning model to predict these omics observations from sequence. By jointly training on many species, our model can leverage both conservation and variation between species, to better learn the effect of individual regulatory elements on gene expression. We will use existing data, which leverages expression differences between closely related yeast strains and massively parallel reporter assays, to evaluate the model’s ability to predict the impact of sequence changes on expression [6,7]. Our ultimate goal is to crack the regulatory code of simple eukaryotes.

Your Tasks

  • Growing cultures of diverse yeasts and filamentous fungi in the Benz lab
  • Preparation of samples for NGS (RNA/ATAC-Seq) and Mass-spectrometry assays
  • Depending on your interest and prior programming experience, contributing to the bioinformatics processing of the data, as well as the development, implementation and evaluation of the deep learning model (Gagneur lab)


  • Currently studying biology, biochemistry or a related subject at the MSc level
  • Strong interest for regulatory genomics
  • Prior experience with bioinformatics methods and machine learning is helpful, but not required
