A systematic review on spatial crime forecasting
Published in Crime Science, 2020
We follow the PRISMA guidelines for reporting this systematic literature review and we analyse 32 papers from 2000 to 2018. We identified several opportunities and strengths there are also some weaknesses and threats for which we provide suggestions.

talks
Towards a crime hotspot detection framework for patrol planning
Published:
I presented a paper from my PhD studies entitled “Towards a crime hotspot detection framework for patrol planning” in the 25th International Conference on Artificial Intelligence in Education (AIED’24).
New Technologies Applied to Public Security
Published:
I had the opportunity to do a 30min presentation in the Training Course for Sergeants of the policemen from RN, Brazil. In my short talk, I explained how spatial analysis and AI can leverage improvements in the way policing is currently being implemented.
Conversational agents for collaborative science learning
Published:
I presented in 20min my PhD proposal to an audience of 30 people, among professors and students. The presentation was about how conversational agents can make science students (~13 year old) can talk online more productively. It was a nice opportunity to have questions about the evaluation procedure that I will use.
Supporting Collaborative Online Science Education with a Transferable and Configurable Conversational Agent
Published:
I presented a paper from my PhD studies entitled “Supporting Collaborative Online Science Education with a Transferable and Configurable Conversational Agent” in the 15th International Conference on Computer-Supported Collaborative Learning (CSCL).
teaching
Workshop: Introduction to IT, Software, Hardware and Peopleware
Workshop, Universidade Estadual do Rio G. do Norte, 2018
I gave a small workshop (around 5h along three sessions) for policemen about what is Information Technology (IT), software, hardware, and peopleware. The course was a requirement for the experienced policemen (+30 years of service) to be promoted. The students were 50-60 years old. It was a nice opportunity to train my teaching skills because I really had to be simple and straightforward in the content explanation. Also, nice to talk to policemen that work ethically (most of them) to make good for society and have in Brazil such a low salary and unstable situation. I also used the workshop to collect some data about what do they think can influence most the spatial distribution of crime, e.g., geographic factors. So I surveyed them to collect data and use in my masters thesis.
Concurrent and Parallel Programming
Undergraduate course, Federal University of Rio G. do Norte, Department of Informatics and Applied Mathematics, 2019
One third of the course was taught by me in a discipline of my MSc supervisor. I proposed project assignments where the students had some basic machine learning problems (e.g., clustering, spatial interpolation, text analysis) where training and/or inference can be done in parallel.
