PhD in Astrophysics - Data Analyst

Vanessa
Lorenzoni

Since I was little, I've been fascinated by the Universe and its mysteries, that's what led me to physics in 2011. Along the way, I completed a master's degree and a doctorate with a focus on astrophysics, where I worked with SQL, Python, and statistical analysis long before they were called "data skills." With my PhD done, I brought all of that into a new field. I joined a consultancy, was placed at a client company from day one as a Data Analyst, and it didn't take long before they invited me to join them directly. In my journey, I also took on the role of bringing data knowledge to non-technical teams through internal courses. Looking back, I was always a data analyst, the subject just changed.

How I work

01

Analytical Thinking

After 12 years in exact sciences and astrophysics, breaking down complex problems step by step just became how I think. It carried over naturally into data work.

02

Communication

Presenting research and data findings to very different audiences, from academic committees to business teams, made communication feel natural over time. I'm always looking to improve, but it's something that flows easily when the moment asks for it.

03

Adaptability

Going from astrophysics to financial data analysis wasn't an obvious path, but it worked. I adapt when I need to, even if the beginning of something new takes a little longer. New challenges don't scare me.

04

Curiosity

Curiosity is just part of who I am, it's what made me fall in love with the cosmos as a kid and end up studying physics. As a data analyst, it's what makes me actually enjoy the work. I genuinely want to know what's hiding in the data.

05

Collaboration

I've always worked alongside people from different backgrounds, researchers, physicists, and now developers, PMs, data engineers, architects. Having different perspectives on the same problem is something I genuinely value. You always come out with a richer view of things.

06

Attention to Detail

In astrophysics, the data doesn't forgive careless mistakes, and neither does a financial pipeline. Working in both worlds made me naturally careful with the details, because one small error can change the whole picture.
