Research Focus

The Institute of Legal Medicine (GMI) at the Medical University of Innsbruck is home to the Austrian Central DNA Laboratory established in 1997. It represents Austria in the European DNA Profiling Group (EDNAP), the Network of Forensic Science Institutes (ENFSI) and the Interpol Monitoring Expert Group (MEG). GMI has a strong focus on technology-based projects involving electrophoresis, real-time PCR, mass spectrometry and massive parallel next-generation sequencing (MPS) strategies. GMI is repeatedly commissioned to handle international casework requests, some of which have received international media attention, such as the identification of the 2004 South Asian tsunami victims (Sri Lanka), the missing children of the Russian imperial Romanov family, the 1973 victims of the regime in Chile, the 2014 students missing from Ayotzinapa in Mexico and various international crime cases.

GMI is home to the mitochondrial (mt)DNA database EMPOP (https://empop.online/), which has become the primary reference source for forensic mtDNA data basing and quality control of mtDNA data over the years. GMI also hosts the autosomal STR database STRidER, which provides freely available, quality-controlled STR allele frequencies to the scientific community (https://strider.online/). Both database projects are key players in several related international initiatives and consortia (STRAND, STRSeq, DNASEQEX, SeqForSTRs, MitoBench).

Furthermore, GMI has proven experience in the assay design and development of MPS tools for archaeo-forensic applications (e.g. Parson et al. 2018) and initial validation of mtDNA MPS applications on Ion Torrent platforms (e.g. Strobl et al. 2020). With new tools (e.g. Madel et al. 2016, Xavier et al. 2019), the research group has made significant improvements in fighting crime and in the field of non-human DNA (e.g. Berger et al. 2019). A prominent research focus was on forensic DNA phenotyping to predict appearance, age and ancestry of an unknown sample from DNA (e.g. Xavier et al. 2020, Heidegger et al. 2020).

GMI is host to the core facility of Metabolomics.

The GMI is home to the “National SARS-CoV-2 Wastwater Monitoring Program of the Austrian Federal Ministry of Social Affairs, Health, Care and Consumer Protection” as well as the corresponding monitoring programs of Tyrol and Salzburg.

General Facts

Research

Increasing the Crime-Fighting Success Rate through Technological Improvements

Walther Parson
The institute plays a key role in addressing internationally relevant issues in forensic human identification by means of modern molecular genetic techniques.

Introducing Mitogenome MPS to Solve Challenging Crime Scene Samples

Walther Parson
The institute leads international research to maximise forensically relevant information content from the mitochondrial DNA sequencing of unknown samples (crime scenes and mtDNA EMPOP data basing) using MPS technologies.

Forensic DNA Phenotyping: Providing Evidentiary Leads by Predicting Externally Visible Characteristics and Bio-Geographical Origin Using DNA Analysis

Walther Parson
Without a reference (e.g. suspect), unknown perpetrators of crime cannot be identified from the current forensic use of DNA. We overcome this major limitation by developing molecular tools to predict appearance, age and ancestry from DNA traces. This allows the construction of composite sketches of unknown trace donors directly from the DNA traces left at crime scenes.

STRidER – STRs for Identity ENFSI Reference Database

Martin Bodner
The institute hosts STRidER, which acts as a worldwide frequency database, quality control authority and software platform for the development of novel tools for the most widely used forensic DNA markers (autosomal STRs).

Complex Pedigrees

Martin Bodner
The institute has contributed to the resolution of complex kinship cases by employing modern DNA methods.

Exposomics and Human Biomonitoring

Herbert Oberacher
The institute is involved in international research projects that aim to develop advanced analytical technology for the detection of pollutants and toxins in biological and environmental samples.

Wastewater Epidemiology

Herbert Oberacher
Wastewater-based epidemiology is a rapidly developing scientific discipline with the potential to monitor real-time data on geographical and temporal trends in exposure to chemicals and pathogens. It involves analysis of the influent to a wastewater treatment plant.

Systematic Toxicological Analysis (STA)

Herbert Oberacher
STA is defined as the application of an adequate analytical strategy for the detection and identification of the greatest possible number of potentially toxic compounds and their metabolites in biological samples. It is an integral part of the medicolegal examination of drug consumption and poisoning. To maximise the forensically relevant information obtained from casework samples, we are developing new and advanced workflows for STA.

Core Facility Metabolomics

Herbert Oberacher
The mission of the Core Facility Metabolomics is to serve as an enabling resource for research and development programs at the Medical University of Innsbruck. We aim to provide expertise and state-of-the-art technologies for the qualitative and quantitative analysis of small bioorganic molecules. Common targets are drugs, pharmaceuticals, endogenous compounds and metabolites thereof included in all kinds of biological samples (e.g. bio-fluids, cells, tissues).
