MsC in Bioinformatics and Biostatistics

I recently obtained a Msc in Bioinformatics and Biostatitsics from Universitat Oberta de Catalunya and Universitat de Barcelona. My capstone project was entitled «Machine learning methods for characterizing single-particle trajectories with anomalous diffusion» under the supervision of Ferran Reverter Comes.

Machine learning methods for characterizing single-particle trajectories with anomalous diffusion

Single-Particle Tracking (SPT) appears to be a potential approach to studying different dynamic processes in the life sciences with recent advances in light microscopy. The physics of life molecules has an inherent instability due to the heterogeneity of free energy states that different types of molecules can show, far from thermal equilibrium and ranging at different scales, from the nanoscale of a single molecule up to the cellular or even organism level. The classification of trajectories is a relevant topic, not only in the biological field at the molecular level but also at the level of animal and human behavior. Besides, this topic combines physical principles with some degree of uncertainty, which habilitates us for exploring the use of ML techniques.


Rankings and Spotify

I have recently presented a contribution in the with Francisco Pedroche on rankings. We have particularized to Spotify. While people around the world stopped, music didn’t: we have shown that during the worst months of the pandemic, the list of the Top-200 hits on Spotify, produced from the streams registered on the popular app, had 18% more songs. The most played songs worldwide, during the months studied, were Dance Monkey (Tones and I), Blinding Lights (The Weeknd), and The Box (Roddy Ricch).

This means that, regardless of whether record companies published new material or not, listeners changed their preferences more often during the pandemic, thus causing an increase in the number of songs that made the lists. Thus, the first quarter of 2019 registered 474 songs on the Top 200 list, whereas in the same period of this year, the number of hits was 557, which represents an 18% increase. This figure reveals a significant increase when compared to the 1% decrease that took place during the same period from 2018 to 2019, or the 9% increase from 2017 to 2018.

Special Issue «Mathematical and Computational Methods against the COVID-19 Pandemics» in Mathematics (Q1 in JCR)

Mathematics Special Issue CoVID-19

Mathematics can also contribute to the modeling of side problems to the pandemics. We point out some of them, such as data quality analysis, network medicine, healthcare services management, the physical spreading of the virus in the environment, the subsequent impact on the economy, and the social response to confinement government measures.

In any case, all the contributions and developments will be beneficial in many ways aside from coping with pandemics. Some potential topics that this Special Issue will cover, but is not limited to, are as follows: Epidemiological dynamics, diffusion modeling, compartmental and SIR type models, human dynamics, agent modeling of structured populations, network medicine, data quality, artificial intelligence and deep learning models, and data analysis of social media

Invited talk at the Master’s Degree in Languages and Technology

Today I have been invited to deliver a talk at the In this talk I have briefly introduced several notions of data science, and in particular network science, in connection with linguistics. Among other things we have discussed that many structural patterns are inherent to linguistics, and are common to different languages.

Master's Degree in Languages and Technology

Among these patterns, we can find Zipf’s law, Benford’s law, and unusual frequencies of certain motifs. We have also seen a tool called SocioViz that permits to download and visualize tweets from Twitter.

Kick off of DaLiCo Eramus + project

I am responsible of the UPV group participating in the Erasmus + project DaLiCo (Data Literacy in Context), jointly with Nacho Despujol and Carlos Turró. Our partners are: Hamburg University of Applied Sciences (HAW), University of Debrecren (ED), and the University of Applied Sciences of Utrecht (HU). We had the kick off meeting in November 7-8n 2019 in Hamburg.

Data Literacy (DL) is defined as the ability to collect, to manage also complex information, to evaluate and to apply data in a critical manner (Ridsdale 2015). This does also include smart use of digital resources. All students in advanced learning, irrespective of discipline, need to acquire this key competence that will allow them to thrive.

Our project, DaLiCo (Data Literacy in Context) will be focused on increasing the visibility, quality and usage of existing Data Literacy activities at the participating universities.

J.A. Conejero accreditated as Full Professor

Last may I have received the acreditation as Full Professor from ANECA (Agencia Nacional de Evaluación de la Calidad y Acreditación), deppending from the Spanish Ministry of Education.

It has been a long and winding road since I started my PhD on 1999, and I did not even think about this then. There have been many collaborators and supervised students that have come along with me during these years. I want to thank them for all what I have learned from them and for sharing a little of their time and their life their time with me.

As W. Churchill said: Now this is not the end. It is not even the beginning of the end. But it is, perhaps, the end of the beginning.
