About

Since 2022, I have been teaching at ISCTE Sintra - Instituto Universitário de Lisboa, where I lecture in Graphs and Complex Networks, Calculus (with Python), and Applied Mathematics. From 2021 to 2023, I also taught Mathematics, Physics, and Computer Science at Instituto Superior de Educação e Ciências de Lisboa.

I am passionate about science and knowledge development, with research interests in mathematical modelling applied to physics, biology, and broader scientific and societal challenges. I am also deeply committed to education, striving to empower learners to master any skill with the right guidance and effort. In line with this, I have volunteered as a teacher of Portuguese and Mathematics for illiterate adults in a social institution.

Beyond academia, I have experience in Data Analysis (backend and frontend), Data Visualisation and Dashboarding, Data Science, and Predictive Analytics. I excel in problem-solving, research, and data interpretation, applying analytical skills to rapidly develop solutions, whether through organisation, teamwork, scheduling, management, programming, or innovation.

As a researcher, I have worked on projects applying mathematical and computational techniques to biological data, specifically studying virus evolution in terms of mutations and virulence. While this research did not prevent the COVID-19 pandemic, projects like these contribute to the scientific foundation that enabled rapid vaccine development.

I hold a Ph.D. from Cranfield University (UK), following an M.Sc. in Physics from the University of Lisbon (Portugal). My doctoral research focused on analysing automotive supply chains and developing a synthetic network model capable of replicating real-world supply chain structures. The model demonstrated high accuracy, allowing managers to predict supply chain structures with minimal data.

In terms of soft skills, determination and hard work have been fundamental in my career. I firmly believe that success is not reserved for geniuses—anyone can achieve their goals with dedication and perseverance.

Metrics description

h-index

A scientist has an h-index if h of his N publications are cited at least h times each, while the remaining (N - h) publications are cited no more than h times each.

https://www.pnas.org/doi/full/10.1073/pnas.0507655102

i10-index

The number of the author's publications that received at least 10 links each.

https://scholar.googleblog.com/2011/11/google-scholar-citations-open-to-all.html

m-index

The researcher's m-index is numerically equal to the ratio of his h-index to the number of years that have passed since the first publication.

https://harzing.com/publications/white-papers/reflections-on-the-h-index

o-index

The geometric mean of the h-index and the number of citations of the most cited article of the scientist.

https://arxiv.org/abs/1511.01545

g-index

For a given set of articles, sorted in descending order of the number of citations that these articles received, the g-index is the largest number such that the g most cited articles received (in total) at least g² citations.

https://doi.org/10.1007/s11192-006-0144-7

w-index

If w articles of a researcher have at least 10w citations each and other publications are less than 10(w+1) citations, then the researcher's w-index is equal to w.
