What do you study? What part of your research are you most excited about?

We study early brain development at the intersection of systems and computational neuroscience. Early brain development feels so alien and costly, evolutionarily speaking. The brain builds huge transient structures that will soon vanish, and most neurons barely fire. In our data, about 99 percent of mouse prefrontal neurons stay below 1 hertz in the first postnatal days—roughly 10 to 50 times lower than in adults. I find this mysterious and fascinating. Is there an advantage to starting so silently? The long periods of silence are the first thing that you notice when looking at neonatal brain activity, and it’s still what fascinates me the most about what I study. To address these questions, we combine large-scale in-vivo electrophysiology, opto- and chemogenetics, and spiking neural network modeling to look at how inhibitory circuits influence network dynamics and neural timescales as they mature, and how their disruption results in neurodevelopmental conditions. 

Are there any traditions or practices from the labs you trained in that you will implement in your own lab?

Lab outings were very outdoorsy in my previous lab. I look forward to carrying on that tradition. Luckily, the lab is on top of a wooded hill, surrounded by great cycling opportunities. The Liège–Bastogne–Liège, one of the oldest cycling races in Europe, passed right by the institute this year! Long term, I dream of a lab retreat in an Alpine hut, close to where I grew up in a small village in the middle of the Dolomites in Trentino, Italy.

What is the best advice you received from a mentor or colleague before opening your lab?

Grow slowly. Stay close to the experiments, rigs and data. Coffee and snacks are consumables, and I should budget for them.

What do you study? What part of your research are you most excited about?

Our lab is interested in specialized neurons in the mammalian auditory brainstem called octopus cells. These incredible neurons have extreme electrical properties that enable them to detect sounds in the environment that occur within less than one millisecond of each other. We combine methods in anatomy and electrophysiology to understand how computations with strict requirements, such as detecting rapid sounds, can adapt over a lifetime of changing sensory experiences. I am most excited for our experiments that examine how descending inputs to the brainstem can influence when and how a neuron responds to a complex sound.

Are there any traditions or practices from the labs you trained at that you will bring over and implement in your lab?

During my postdoc, lab meeting presentations ended with an “away from the bench” slide. This was a chance to share a nonscientific update with the group. It could be a photo from a hike you went on last week, a cute picture of your cat or a funny moment from the show you’ve been catching up on. My lab will follow this tradition to foster a culture where we feel comfortable celebrating who we are with each other.

What is the best advice you received from a mentor or colleague before opening your lab?

Starting a new lab means you are going to get a ton of conflicting advice and guidance about what you should do. The best advice I was given was to hear everyone out but only put into action what feels true to yourself and your vision for your science. I was reminded that there are many parallel paths to success.
