We are Brandeis science: Madelen Díaz

There is no rule that says scientists have to look or act a certain way. Scientists can be funny and outgoing, athletic and artistic. They come from all different backgrounds and have all different interests. At Brandeis, our scientists are as diverse as the groundbreaking research they engage in. This on-going series is inspired by This is What a Scientist Looks Like

The music of the mind

Where are you from?

I was born and raised in Miami, Fla. after my parents emigrated from Cuba.

What do you research?

I currently research the neuronal circuitry responsible for circadian rhythm in the fruit fly (Drosophila melanogaster). Why do we use the fruit fly to study circadian rhythm? Fruit flies sleep at night and even sleep the siesta during the afternoon. Several of the molecular proteins responsible for these behavioral oscillations are conserved across species. We use complex genetic tools, behavioral assays, and several imaging techniques to see how these circadian neurons coordinate with each other to produce their active/sleep cycle throughout the day.

What is your biggest passion outside of science? 

My passion outside of science has always been classical piano. I’ve been playing since I was 6 years old. There is something incredibly relaxing about immersing yourself into the music that you forget that ever-growing “to-do” list.

How do you define discovery, and how does it make you feel?

I would term discovery as obtaining an unexpected or controversial result. It’s very exciting thinking of the possibilities of a new discovery and how this can potentially contribute to the “big picture.” It can also be nerve-wracking because of the uncertainty of not knowing what to do next or where to look. The most difficult part of graduate school is to continue working through all of the uncertainty.

What do you do to unwind, after a long day at the lab?

After a long day in the lab, I most commonly relax by baking desserts or playing piano. On weekends, I like to go out salsa dancing or traveling New England.

 The thrill of discovery

As a kid, what did you want to be when you grew up?

As a really little kid I wanted to be an artist, and then I wanted to be a vet because I love animals. But I actually knew partway through high school that I wanted to be involved in research science.

What do you research?

I study the CRISPR/Cas9 genome editing system. It is the latest generation of genome editing technology that allows the researcher to create specific mutations in the genomes of their model systems. This allows you to understand what a specific gene does and why it is important. I’m working to improve the efficiency of the system to add in specific mutations.

How do you define discovery and how does it make you feel?

Discovery means being the first person ever to see a result or data trend — and recognizing that it means something. I get an absolute thrill from making a discovery — it’s better than any other adrenaline jolt out there (and I’ve gone skydiving a couple times). The quest keeps me motivated, especially during the stretches when nothing seems to be working with my project.

Besides science, what do you nerd out about?

Outside of the lab, I love science fiction/fantasy books, movies and TV shows. I even took a class in college called “Tolkien’s Middle Earth” — it was pretty awesome, especially since our homework most of the semester consisted of reading “The Lord of the Rings.”

What’s one, non-career goal?

I’d love to become totally fluent in Spanish. I’ve studied it for years and have spent time in Spain, so I would still describe myself as proficient. I’m planning a trip to South America soon and hope I can get over the hump there.

Tiny discoveries, big excitement

Where are you from?

I’m from Smithfield, Va., a small town whose biggest employer runs a pork processing plant. If you ever see Smithfield bacon in the grocery store, it’s likely from my hometown!

What did you want to be when you grew up?

Growing up, I was really indecisive. I wanted to be a writer, an architect, an astronomer, even a princess. I finally settled on meteorology in high school and chose a college with a great meteorology program. About a year into the program, though, I began to think I might have been wrong yet again. I took a neuroscience class the next semester, and found it fascinating. I had never been so excited about a field before, and my indecision vanished.

What do you research?

I’m researching the link between sleep and memory in fruit flies. It’s been known for a long time that sleep is important for storing long-term memories, but exactly how these are linked in the brain isn’t well understood. A colleague and I recently found that memory neurons are actively involved in sleep. This means that sleep doesn’t just support memory; they’re anatomically linked in the brain.

How do you define discovery and how does it make you feel?

Some days, after a long and successful experiment, I’ll realize that I’ve just uncovered a fact that no one else knows. Until I tell someone else, I’m the only one in the world to know this particular fact. These kinds of tiny discoveries are exciting, and I want to share them with everyone I know. It’s okay that it’s no longer my little secret, because I’ll discover another one in a few days.

What is one, non-career related goal?

Outside of the lab, one of my goals is to become fluent in German. My husband is from Germany, and I would love to be able to engage with his friends and family and get to know them better. They are great people, and I want to keep improving and make them proud.

 A mind-blowing mystery

 Where are you from?

That’s a complicated question. I was born in Washington, D.C. but lived in New Canaan, Conn., for most of my life. My family moved to London during my middle school years, where Britain’s dedication to science education certainly helped me to develop my passion.

What do you research?

I work with physics professor Gabriella Sciolla on the search for dark matter, one of the greatest mysteries of the universe. As it turns out, dark matter accounts for 85 percent of the mass of the universe — which blows my mind. I would very much like to find out what most of the universe is made of, and how these materials interact with the matter out of which you and I, the stars, and everything else we perceive, is made.

As a kid, what did you want to be when you grew up?

When I was 8 years old, I wanted to be an oceanographer — I wanted more than anything else to probe the fathoms of the sea. That was my dream for nearly a decade and during high school, I worked more than 300 hours at The Maritime Aquarium in Norwalk, Conn. Through my experience there, I learned that I wanted to understand more than just what is out there — I wanted to understand how everything works and why it came to be that way. As I continued my education, I came to feel that those questions were best answered through physics.

What got you into science?

Dirt. Good old-fashioned digging in the dirt. I was very fortunate growing up — my parents made sure that my three siblings and I always had a yard in which to play. Pill bugs, rocks, flowers, frogs — just about anything I could find in the yard rapidly transformed into an experiment.

What’s the coolest place you’ve ever been?

CERN’s Large Hadron Collider, 150 meters underground at the ATLAS detector. It is enormous!
