About me

Hi, I'm a data scientist at Dell Technologies, where I work in projects that aim to improve pricing decisions with data analysis and statistical models. I also hold a PhD in physics from the Federal University of Rio de Janeiro (UFRJ), where I have studied light-matter interaction related phenomena. My main research areas were nano-optics, nanophotonics, plasmonics, and two-dimensional materials.

In my free time I enjoy playing video games (mostly RPGs and strategy games), listen to music (and learn a little bit), and also read about different topics. The purpose of this website is to make public some of my study materials in data science and the work I've done in physics. I believe that freely sharing your work online has great potential to help others, who may find value on the content you create.

Study materials

Here I just want to share some of my data science mini projects and study materials.

Mathematical optimization with Pyomo

Artificial intelligence is not just about machine learning. Mathematical optimization is the perfect tool for harnessing business decision making, while it also adds value to predictive models.

FIFA 20 - mini data science project

Web scraping of data from the FIFA Index website, exploratory analysis, and development of an API and a web app for players' salaries and positions predictions.

NLP with disaster tweets

Natural language processing study with a kaggle dataset.

House prices regression

A small study on regression with linear and gradient boosting models.

Recommendations

Below are some recommendations of books, articles, and other materials that have had a significant impact on my professional life.

Physics

  • A Brief History of Time, by Stephen Hawking. I read this book when I was at High School and it was very important to develop my interest and open my mind to physics.

  • Carlos Farina’s lessons. Farina, my academic advisor since 2015, is well known for being passionate about physics and teaching, and is very good at motivating his students. It was no different with me, who became fascinated about the quantum vacuum effects and other topics. A glimpse of the things he used to talk about can be found in this awesome review paper about the Casimir effect and in this talk about Christiaan Huygens (In portuguese).

  • Photons and atoms: introduction to quantum electrodynamics, by Cohen-Tannoudji. This is a more technical book about quantum electrodynamics and atom-photon interactions. I recommend it to any physicist who wants to have a deep understanding of the theory behind light-matter interactions.

  • Veritasium (YT channel). I ever found amazing how exceptional this channel is. The diversity of topics, the presentation, and the quality of all content are extraordinary.

Finance

  • The Little Book of Common Sense Investing, by John Bogle. In this book I found the only way to invest in the stock market: low cost well diversified index funds. I consider this book to be a must for anyone feeling lost in the world of investments. If you like it, you should also take a look in Ben Felix’s YT channel. Yes, I’m a proud Boglehead!

  • Principles of Corporate Finance. This is a book on corporate finance with a more academic approach. Even though I left academia, my preference for learning from academics remained. I must mention that I wouldn’t have come across this book if this spectacular course by Professor Andrew Lo was not available for free on YouTube.

  • The Plain Bagel (YT channeç). “Plain and simple”. I’ve learned and became more interested in the world of finance much because of the content present in this channel. It’s worth checking out.

Artificial Intelligence

Causal Inference

  • The book of Why: The New Science of Cause and Effect, by Judea Pearl. Only after I started working with data science that I realized how limited machine learning is as a tool for understanding the causes of observable effects (try using a ML model to estimate the effect of raising prices of hotel rooms on their occupation rates to see what happens!). This book is an amazing introduction on causal inference, with really interesting comments on the limits of the current state of AI (and even on the limits of statistical analysis!).

  • Causal Inference for the Brave and True, by Matheus Facure. An excellent starting point for whom wishes to dive into the causal inference wonderland. It is really well written and provides many other references on the field.
