Since September 2018, I am an Associate Professor of Bioinformatics at the UCLouvain, in Belgium, and director of the Computational Biology and Bioinformatics (CBIO) group. I am located in the de Duve Institute, on the medical campus in Brussels, where I run a research group and teach at the faculty of pharmacy and biomedical sciences (FASB).
I am an avid open research advocate and make every possible effort to make my research reproducible and openly available. I am a Software Sustainability Institute fellow, a Data and Software Carpentry instructor, and an affiliated member of the Bioconductor project.
I am also involved in the Bullied Into Bad Science campaign, an initiative by and for early career researchers who aim for a fairer, more open and ethical research and publication environment. In 2017-2018, I was also part of the eLife Early-career advisory group and, since 2017, am a #ASAPbio ambassador.
Before that, I was a Senior Research Associate in the Department of Biochemistry at the University of Cambridge. It’s at the Cambridge Centre for Proteomics and the Computational Proteomics Unit (my former research group in Cambridge) that I started working on various aspects of quantitative and spatial proteomics, developing new methods and implementing computational tools with a strong emphasis on rigorous and reproducible data analysis. I am also a visiting scientist in the PRIDE team at the European Bioinformatics Institute, and the Cambridge Computational Biology Institute.
And even before that, during my MSc and PhD work, I studied micro-evolutionary genetic patterns of the Broom leaf beetle Gonioctena variabilis in Southern Europe (Gatto el al., 2008), the application of short interspersed mobile elements (SINEs) to study the evolution of cetaceans, and the applicability of the General Time Reversible nucleotide substitution model in the light of differential lineage sorting (Gatto el al., 2006). I also spend 3 years in industry working on genomic and transcriptomics data, in particular the microarray quality control (Shi et al., 2010).
As pointed out by D. Donoho, An article about computational science in a scientific publication is not the scholarship itself, it is merely advertising of the scholarship. The actual scholarship is the complete software development environment and the complete set of instructions which generated the figures. This directly applies to high throughput biology data analysis and I strongly believe that being able to reproduce the complete set of results, replicate an analysis with new data and track the evolution of the work that lead to the scientific novelty are essential aspects of the process of doing research. Hence, I regard the development of scientific software as well as agile and robust analysis methodologies that facilitate reproducible research, an important aspect of my scientific activity.
Clarity and traceability of the data and the analysis methodology enable us to better understand what we do, how and why we do it and consequently exploit the data and comprehend the biology. While not sufficient, these are nevertheless necessary requirements for effective data-driven science.
The collaborative and interdisciplinarity nature of much of the research in biology calls for a open approaches, influenced by the open source and free/libre software movements, from communication between stake holders, open research and development to open dissemination of all research outputs.
My work on the design and implementation of reproducible mass
spectrometry-based proteomics data analysis pipeline has materialised
in the development of the
(Gatto et al., 2012)
package to manipulate, process and analyse quantitative proteomics
MSnbase infrastructure also supports the work on the
statistical learning applied to spatial proteomics (see below). The
synapter package and
the associated publications
(Bond et al., 2013 and
Shliaha et al., 2013)
addresses MSE label-free quantitation, optionally including
ion mobility separation.
In biology, localisation is function: knowledge of the localisation of
proteins is of paramount importance to assess and study their
function, and spatial proteomics is the systematic study of the
sub-cellular localisation of proteins and changes thereof
(Gatto et al., 2010). Since
2010, I have developed novel software and machine learning approaches
enabling more reliable and systematic inference of protein
localisations using quantitative proteomics. This work has
(Gatto et al., 2014)
that implements various established classification algorithms,
effective visualisation techniques
(Gatto el al., 2015) as
well as novelty detection
(Breckels et al., 2013)
and transfer learning, harvesting GO annotations of microscopy-based
methods to improve the spatial resolution of experimental spatial
(Breckels et al., 2016).
Over the years I have been involved in many teaching activities, ranging from beginners and advanced R courses, genome biology, proteomics bioinformatics, integrative omics, scientific computing as part of the MPhil in Computational Biology in Cambridge, as well as several Software and Data Carpentry bootcamps. All my teaching material is available in the TeachingMaterial repository.
Please do get in touch if you are interested in running workshops.
