Yesterday, the wonderful students of our research group @log_ufpb surprised me for my 41st birthday at LASER-UFPB. I was really moved by this incredibly thoughtful gesture, and honestly, I couldn't ask for better company. What a dream team!

Extremely happy to reunite with my first generation of research students from UFPB 🤩! I can't thank them enough, not only for their brilliant work but also for their invaluable and loyal friendship. It’s not an overstatement to say they’ve become like a second family to me ❤️.

During her stay, Giulia collaborated with us in our lab and presented a seminar to our team. We also had a great time showing her some of our city's tourist attractions! We will miss you, Giulia, and we hope to see you again soon!

This past month, our research group had the pleasure of hosting Giulia Dotti, a PhD student from UNIMORE (Italy), at LASER-UFPB.

For the past several months, we had the privilege of hosting the fabulous Vinicius Loti de Lima as a postdoc. Now he will start a new chapter in his life, and I am sure he will continue to make us proud. Vinicius, you left a mark in our hearts, and you will be greatly missed.
