Paige Arnold

Postdoctoral Fellow

As a South Florida native, Paige spent most of her childhood dodging alligators and sunburns but also developed a deep fascination with nature. As an undergraduate at Duke University, she studied Biology and Science Policy and pretended to care about college basketball. She then pursued a PhD in Cancer Biology at Memorial Sloan Kettering Cancer Center, where she studied stem cell metabolism and became a TCA cycle aficionado. Paige decided to venture across York Avenue and to a new domain of life for her postdoc and joined the Marraffini Lab to study the role of metabolism in bacterial defenses against viruses. Outside of lab, Paige enjoys traveling, finding new plant-based food around the city, and spending time with her cat, Lenny.

Naama Aviram

Postdoctoral Fellow

Naama grew up in the vibrant city of Tel Aviv, right on the coast of the Mediterranean Sea. She received her PhD from the Weizmann Institute where she studied eukaryotic cell biology. Although organelles will always stay dear to her heart, Naama followed her passion and joined the Marraffini lab for her postdoctoral training, where she now focuses on bacteria and their sophisticated immunological memory. She claims she plays the bass but no one in the lab has heard her play yet. Her other hobbies include scuba-diving, exploring the New York culinary scene, and losing balance trying to do yoga.

Christian Baca

Graduate Fellow

Christian grew up in the small-ish town of Lake Elsinore, CA. He did his undergraduate studies at UC Irvine in biochemistry and molecular biology, where he got to work with lasers, chaperones, and carnivorous plants. He then made the move out to NYC and is now getting to hang out with lots of phages and bacteria alike. Outside of CRISPRing in the Marraffini Lab, Christian enjoys trying to make gains at the gym, playing heavy riffs on guitar, and eating chocolate.

Maj Brodmann

Postdoctoral Fellow

Maj grew up in Basel, a Swiss city best known for big pharma and sports (go Fc Basel!). She received her PhD in Microbiology from the Biozentrum, University of Basel, studying type VI secretion systems in bacteria. Her passion for microbiology and her favorite bacterium Francisella led her to New York to join the Marraffini lab, where she now focuses on Francisella's defense rather than offense. Next to science, she enjoys travelling to remote islands, horseback riding and concerts.

Clare Cahir

Graduate Fellow

Clare is the fourth New Jerseyan, third TPCB student, and second Cla(i)re in the Marraffini lab but the first to start a crafting club at Weill Cornell Medicine. In undergrad at the University of Notre Dame, Clare studied Chemistry, Italian, and the Art of Tailgating. When not cheering for her favorite team, Clare could be found in lab studying tuberculosis, where she discovered Biology is pretty cool. Clare started grad school hoping to combine her love for Chemistry and Biology and soon after found her newest calling: exploring the NYC food scene for her food Instagram @FeedOurPhDs. Besides enjoying free food, Clare likes long walks, eating ice cream, and dodging cars on her used bike.

Héloïse Carion

Graduate Fellow

Don’t be thrown off by the aggressive accents on her name, Héloïse is a SoCal girl at heart. Hailing from sunny San Diego, she went up north to UC Berkeley where she studied Bioengineering and dabbled in E. coli and phages. Her love for these little viruses led her across the country to the Marraffini lab, where she has learned to appreciate a broader array of microbes and the charm of changing seasons. When she’s not in the lab, Héloïse can be found running, doing handstands, sunbathing, and searching for the best California burrito NYC has to offer.

Alice Cassel

Graduate Fellow

Alice was raised on the rocky, evergreen shores of the Puget Sound in the town of Bremerton, Washington. She harbors a deep-seated love of marine life after her years of volunteering at the Seattle Aquarium; however, she landed among the wheat and mountains of north Idaho to pursue undergraduate studies at the University of Idaho. She dabbled in studying wildflower phylogenetics and soil microbiomes, but her true passion for microbiology led her to Rockefeller to join the Marraffini Lab for her PhD. When she isn’t CRISPRing and growing all manner of extremophilic archaea (the most under-appreciated domain of life!), Alice can be found hanging out with her cats, running around Central Park, dancing to 1980s synthpop, and crate-digging for vinyl records.

Chloe Fishman

Graduate Fellow

Chloe grew up in the Bay Area, known for majestic Redwoods and the roaring of Tesla engines. She completed her undergraduate degree at Georgetown, where she investigated how microbial communities survive in extreme environments as analogs to other planets. Then as a research associate at the Gladstone Institutes in San Francisco, she engineered bacterial elements into molecular tools and stretched the limits of her potential as a tech bro. So she transitioned to New York, where she’s excited to explore how bacteria defend themselves against their viruses and how this is evolutionarily related to our own immune systems. Outside of lab, Chloe can be found thinking about her puggle named Puggle, seeking out all forms of rice and beans, convincing her cello teacher she practiced between lessons, and racing against citibikes in Central Park.

Calvin Herman

Graduate Fellow

Calvin is a city person at heart. He was born and raised in Jakarta, the world’s second most populous city, and later grew up in New York City, the largest in the United States. For his undergraduate studies, he stayed in NYC and attended Hunter College, where he majored in biology as a Macaulay Honors Scholar. During his free time, Calvin enjoys exploring NYC, being active, and having delicious meals at various restaurants.

Raphael Hofmann

Postdoctoral Fellow

Raphael grew up hiking in the Swiss Alps and around his quaint village in Eastern Switzerland. These days, he goes hiking on the Queensboro bridge to get to work every day. He received his PhD in Biological Chemistry at ETH Zürich, studying protein modifications. In the Marraffini lab, he is excited about combining his PhD field with CRISPR and microbiology. He patiently teaches phages some chemistry, and impatiently waits for the snack drawer to be refilled. In his spare time, Raphael loves traveling, sounding the trumpet, immersing himself in nature, and biking around NYC.

Vivian Li

Graduate Fellow

Vivian grew up in Vancouver mostly before moving to Montreal to complete an honors degree in biology from McGill University. After spending several years studying the cell cytoskeleton, she decided to delve into the world of systems neuroscience as an RA at Rockefeller. Now, as a graduate student, she once again has switched disciplines to study bacterial defense systems. Outside of the lab, Vivian is a fashion enthusiast, who is also passionate about ceramics and fine art. On a sunny day, you’ll find her hiking with her greyhound Jellybean or exploring the endless vintage shops in New York.

Nia Lyn

Graduate Fellow

Nia is a NYC native and very biased to the greatest city in the world. She earned her BS in Biology from Brandeis University and spent most of her time in the mouse facility. After graduating she worked as an RA at Rockefeller and loved it so much that she joined the graduate program. Nia has worked with rats, mice, mosquitoes, and now bacteria. She can safely say that mice were the smelliest. When not in lab, you can find Nia watching reality tv and emailing ABC to make her the new host of the Bachelor.

Adriana Mejia

Graduate Fellow

Adriana was born in Peru and earned her BS in Biology from Universidad Peruana Cayetano Heredia. She started doing research on synthetic biology, but her interests eventually shifted to the human microbiome while working as an RA at the University of Pennsylvania. In her free time, Adriana can be found at the gym, on TikTok, or blasting Bad Bunny.

Cam Roberts

Graduate Fellow

If you ask Cam where she is from, she’ll probably say Portland, Oregon, but actually she was raised in Pasadena, California, a suburb outside of Los Angeles. She received her undergraduate degree from Reed College where she learned that bacteria do amazing things! She fell in love with bacterial pathogens and the host-pathogen battle when she was a research assistant at the Oregon Health and Science University. Her quest to understand bacteria is continuing in the Marraffini Lab. Cam’s favorite thing to do is swim (or stare at) alpine lakes, for which she is willing to hike many miles to reach. If not in lab, you can probably find her biking (and risking her life!) on the Queensboro Bridge.

Kailey Slavik

Postdoctoral Fellow

Kailey is (currently) the sole representative of the Midwest in the Marraffini lab, hailing from the mighty metropolis of Chicago. She first fell in love with viruses while completing her undergraduate studies at University of Wisconsin-Madison, and went on to complete her PhD in Virology at Harvard University. Kailey has studied all things Drosophila— their genetics, viral pathogens, and innate immunity. She now plans to leave her fruit fly days behind and is bringing her passion for virology and biochemistry to the world of phage immunity. When she’s not in lab, Kailey spends her time searching NYC for the perfect jukebox, tending to her garden in Greenpoint, and fermenting anything and everything.

Gianna Stella

Graduate Fellow

Gianna completed her Bachelor's in Bioinformatics and Master's in Computational and Medicinal Chemistry at Stevens Institute of Technology. In 2019, she joined the Tri-Institutional PhD Program in Chemical Biology to explore her interest in bacteria. When not in lab, she can be found flying her giant octopus kite in Central Park or working on a quilt.
