Michael has is an internationally recognised expert in the field of transcriptomics, next-generation sequencing technologies and bioinformatics. His current scientific interest focuses on investigations of gene expression and alternative splicing patterns in distinct structures and cell types of the healthy human brain and perturbation of transcriptome profiles during the onset and progression of neurological disorders including multiple system atrophy, epilepsy, amyotrophic lateral sclerosis and chronic fatigue syndrome. Michael is also interested in exploration of cancer-specific alterations in transcriptome profiles towards identification of novel biomarkers such as circular and non-protein coding RNAs.

During his PhD studies and subsequently as a postdoc at the German Centre for Rheumatism Research, Michael specialised in investigating the influence of the sequence polymorphism within the promoter regions of MHC class II genes in several inbred mice strains (Janitz et al. 1997; Janitz et al. 1998; Cowell et al. 1998).
Joining the Max Planck Institute for Molecular Genetics (MPIMG) converged with Michael’s growing interest in studying transcription at the genome-wide level. Amongst others, he was involved in collaborative projects to characterise cDNA sequences on the level of the whole transcriptome in mice T helper cells and bovine brain (Gutjahr et al. 2005; Jann et al. 2006), respectively.
While at the MPIMG, Michael and his research group focused on developing a transfected-cell array as a high-throughput genomic tool for functional analysis of genes and their products (Vanhecke and Janitz 2004). This resulted in application of the cell arrays for subcellular protein localisation studies (Hu et al. 2006; Hu et al. 2009; Hu et al. 2010), protein-protein interaction screens (Fiebitz et al. 2008), and functional promoter analysis (Cheng et al. 2010). In addition, with collaborative partners in national and European Community research programs, he applied gene expression profiling studies to identify the genes involved in T helper lymphocytes type 1 immune response (Niesner et al. 2008) and differentiation of murine palatal development (Nogai et al. 2008). His research group also developed miniaturised microarray platforms for DNA hybridization studies using PNA- (Bauer et al. 2004) and LNA-modified oligonucleotide probes (Guerasimova et al. 2006; Liu et al. 2006 and 2007), thus contributing to more efficient exploration of the genome structure and function.
Since his appointment at UNSW Michael has been focused on exploration of different segments of human and mouse transcriptome using combination of Illumina and nanopore DNA and RNA sequencing as well as unique analytical pipeline combining in-house and publicly available bioinformatics tools. He and his team provided first insights into non-protein coding transcriptome of different regions of the human cortex, both in health (Mills et al. 2013; Mills et al. 2015a; Mills et al. 2015b; Bliim et al. 2019) and neurological diseases such as Alzheimer’s disease (Twine et al. 2011; Mills et al. 2013; Mills et al. 2014), multiple system atrophy (MSA)(Mills et al. 2015c; Mills et al. 2016) and epilepsy (Mills et al. 2020) as well as cancer (Takenaka et al. 2016; Chen et al. 2017a). His recent research has been concentrated on circular RNAs (circRNAs) genome-wide expression patterns in the normal human (Chen et al. 2019) and mouse brain (Chen et al. 2018) as well as MSA (Chen et al. 2016) and endometrial cancer (Chen et al. 2017b).
Current research projects aim at understanding of circRNA-miRNA-mRNA networks in epilepsy and amyotrophic lateral sclerosis as well as gynaecological malignancies. Another emerging avenue of Michael’s research is exploration of RNA post-transcriptional modifications in healthy human tissues and cancer using nanopore direct RNA sequencing. Michael’s quest for the discovery of circRNAs, which might serve as molecular biomarker for MSA and endometrial cancer, constitutes another important element of his research program.
