Talk: <\/span>Women in science, and in bioinformatics<\/b><\/span><\/span><\/p>

\u00a0<\/div>
Throughout human history, women have played secondary roles in all activities outside their homes. Despite the fact that in recent centuries, and more intensely since the 20th century, women’s experiences and professional performance have intensified and been expanded, with a lot of effort, sacrifices of their personal lives and breaking of paradigms, especially social models, problems still persist in the 21st century, such as lower pay for positions with the same activities, less participation in leadership roles and greater effort to be recognized at work, which also occurs in scientific areas. In this talk, I will begin by highlighting the role of women in importante research and scientific discoveries throughout history. I’ll also talk about Brazilian female scientists who are pioneers in their fields, including including computer scientists and bioinformaticians. Next, I’ll show some of the United Nations’ recommendations and initiatives for girls and women, especially in education, science and technology. And I’m going to talk a bit about my personal experience in bioinformatics research, female leadership and management at the University of Brasilia. Finally, I will offer some reflections on women scientists, especially in the hard sciences and STEAM areas (Science, Technology, Engineering, the Arts and Mathematics). The aim of the lecture is to share ideas on the issue of women in science and to motivate young female students to think about this topic and to pursue, and persist in, working professionally in research, development and innovation, in bioinformatics.<\/span><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Talk: Cores in the Qualitative Analysis of Paramater-Rich Chemical Reaction Networks<\/strong><\/p>

Parameter-rich CRNs are built upon kinetic laws that have sufficient\u00a0flexibility to allow the independent choice of fixed-point coordinates and the\u00a0absolute numerical values of the non-zero entries of the Jacobian. Although\u00a0this seems to be a tall order, Michaelis-Menten and generalized mass action\u00a0kinetics are of this type. In this setting, the existence of choices of
parameters that make a given inner fixed point Hurwitz unstable is\u00a0determined entirely by the stoichiometric matrix.\u00a0The existence of parameter choices that ensure certain dynamical properties,\u00a0such as the existence of unstable fixed points in this setting depends only\u00a0on the existence of certain sub-matrices of the stoichiometric matrix.\u00a0Minimal subsystems of type have been called cores. Of particular interest\u00a0are unstable cores, which ensure the existence of dynamical instabilities\u00a0and the autocatalytic cores introduced by Ph. Nghe. It turns out that\u00a0autocataltyic cores are the proper subset of unstable cores that have\u00a0the form of Metzler matrices. Autocatalysis, therefore can always act as\u00a0source of instability given suitable choices of parameters, but there are\u00a0also other causes of dynamic instability, entirely unrelated to autocatalysis.<\/p>

Talk: Explanation and Interoperability<\/b><\/p>

It is well-known by now that, of the so-called 4Vs of Big Data (Velocity, Volume, Variety and Veracity), the bulk of effort and challenge is in the latter two: (1) data comes in a large variety of representations (both from a syntactic and semantic point of view); (2) data can only be useful if truthful to the part of reality that it is supposed to represent. Moreover, the most relevant questions we need to have answered in science, government and organizations can only be answered if we put together data that reside in different data silos, which are produced in a concurrent manner by different agents and in different points of time and space. Thus, data is only useful in practice if it can (semantically) interoperate with other data. Every data schema represents a certain conceptualization, i.e., it makes an ontological commitment to a certain worldview. Issue (2) is about understanding the relation between data schemas and their underlying conceptualizations. Issue (1) is about safely connecting these different conceptualisations represented in different schemas. To address (1) and (2), we need to be able to properly explain these data schemas, i.e., to reveal the real-world semantics (or the ontological commitments) behind them.\u00a0\u00a0In this talk, I discuss the strong relation between the notions of real-world semantics, ontology, and explanation. I will present a notion of explanation termed Ontological Unpacking, which aims at explaining symbolic representation artifacts (conceptual models connected to data schemas, knowledge graphs, logical specifications). I show that these artifacts when produced by Ontological Unpacking differ from their traditional counterparts not only in their expressivity but also on their nature: while the latter typically merely have a descriptive nature, the former have an explanatory one. Moreover, I show that it is exactly this explanatory nature that is required for semantic interoperability. I will also discuss the relation between Ontological Unpacking and other forms of explanation in philosophy and science, as well as in Artificial Intelligence. I will argue that the current trend in XAI (Explainable AI) in which \u201cto explain is to produce a symbolic artifact\u201d (e.g., a decision tree or a counterfactual description) is an incomplete project resting on a false assumption, that these artifacts are not \u201cinherently interpretable\u201d, and that they should be taken as the beginning of the road to explanation, not the end. Finally, I will illustrate our approach with the unpacking of a prominent Viral Conceptual Model (VCM).\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Talk: Data-driven patient stratification and drug target discovery with clinical information and omics data<\/b><\/p>

Medical information (electronic medical records) accumulated in daily medical practice can be a valuable asset that has the potential to be effectively utilized for better medical care and drug discovery. On the other hand, there have not yet been any remarkable successes in drug discovery, and there are still a number of issues to be solved in terms of data to be handled by AI. On the other hand, comprehensive analysis of biomolecules (omics analysis) has become a more familiar approach due to rapid technological innovation and cost reduction. There is a growing movement to compile databases of omics analysis results from patient-derived biopsies or blood samples as a means of gaining data-driven knowledge and understanding of diseases. However, due to the comprehensiveness of the data, it is not trivial to obtain knowledge from the data. The medical information and omics data are derived from patients in need of better medical care and new drugs, and are expected to revolutionize the drug discovery process, which has conventionally involved screening of drug candidate compounds in animal experiments. Therefore, we have been developing a novel method for patient stratification using such heterogeneous data in order to realize precision medicine, a new trend in drug discovery, by utilizing clinical information and omics data. In this presentation, I will introduce our approach to stratify diseases into subgroups without relying on prior knowledge such as existing biomarkers and diagnostic criteria, and to find drug targets based on the characteristics of these subgroups.<\/p>
