Aditi Narayanan, Editor-in-Chief
Aditi is a graduate student in Biology at Caltech. Her interests include interactions between microbes and their environments and scientifically informed public policy.
Nicole Wallack, Senior Editor
Nicole is a graduate student in Planetary Science at Caltech. When not studying the atmospheres of distant planets she is frequently seen ranting about the importance of the New American Cinema movement as an influence on modern film.
Namita Sarraf, Senior Editor
As a graduate student in Bioengineering, Namita spends her days thinking about DNA computers that can process information, make decisions, and maybe even learn. Her favorite activities include drinking tea, pretending to be a musician, and waiting in line at the latest hot LA brunch spot.
Alison Koontz, Senior Editor
Alison Koontz is a Biology graduate student studying questions in developmental biology and stem cell biology, under the guidance of Dr. Marianne Bronner. When she isn't doing science, she can usually be found scribbling poetry, performing in choreopoems, or trying to convince people that existence is just performance art.
Heidi Klumpe, Senior Editor
Heidi is a graduate student in the Elowitz lab at Caltech. She studies how cells process information from their environments. She daydreams about a future where robots do all our experiments, and we can compose genomes as easily as poems.
Jeremy Bernstein, Editor
Jeremy grew up in Manchester, England and moved to California to work on his tan... Ahem. I mean PhD. He studies artificial intelligence and neural networks.
Melba Nuzen, Editor
Melba is an undergraduate student studying computer science. She loves playing and listening to classical music and jazz for piano. In her free time, she likes reading sci-fi and fiction novels and visiting LA's museums.
Reem Abdel-Haq, Editor
Reem is a graduate student in Biology at Caltech exploring the connection between diet, the gut microbiome, and Parkinson’s disease. When not in the lab, she can be found at the movies, exploring over-priced coffee shops around LA, or at a wine and paint event.
Katie Page, Editor
As a graduate student in Chemistry, Katie spends her days thinking about how membrane proteins are made in the cell. When not in the lab, she can be found at the gym lifting heavy objects and (trying to) walk on her hands.
William Poole, Editor
William is a scientist and developer bridging synthetic biology, machine learning, and statistical physics. Before beginning his PhD in Computation and Neural Systems at Caltech, William taught high school mathematics, worked at the Institute for Systems Biology in Seattle doing cancer-related bioinformatics, and received his B.S. from Brown University in Biological Physics.
Elise Tookmanian, Editor
Elise is a Chemistry graduate student studying how specific membrane components protect bacteria under stressful conditions. To manage her own stress, she stays active with soccer or rock climbing, pets her cat, eats food with friends, and goes to therapy.
Phelan Yu, Editor
Phelan is a graduate student in physics at Caltech, specializing in ultracold matter, quantum sensing, and precision measurement. He builds experiments to test theories about fundamental symmetries of the universe. A transplant from the Northeast, Phelan spends his free time hiking, reading, and being confused about the seasons.
Usha Lingappa, Graphics Director
Usha is a graduate student in geobiology at Caltech, studying the history of photosynthesis using both modern microbes and ancient rock. She loves to draw and paint, and enjoys combining her interests in Earth science and art by bringing along watercolors when she does fieldwork. She has three cats.
Ren Marquez, Photography
Ren is a graduate student in geochemistry. He is interested in the early solar system and the deep sea. Originally from the Philippines, he is constantly cold and on the lookout for bigger blankets or any other ways to keep warm.
Sharon Chen, Analytics and Website Design
Sharon is a graduate student in Social and Decision Neuroscience, exploring the neurocomputational basis of emotion and behavior, and its changes in psychiatric disorders. She made a novel-writing website and has written a novel on it, she loves reading and games, and she is a fan of BTS.
Krittanon "Pond" Sirorattanakul, Social Media Manager
Motivated to understand and eventually mitigate seismic hazards, Pond studies a newly-discovered form of earthquake known as a slow earthquake, which has prolonged duration up to a few years. His hometown of Bangkok, Thailand, a city with the best food in the world, gave him a love of cooking.
Giuliana Viglione, Editor-at-Large
Giuliana is an oceanographer-turned-science journalist. During her PhD, she used underwater robots to study climate change in Antarctica.
Ollie Stephenson, Editor-at-Large
Ollie is a graduate student in geophysics at Caltech and a cofounder and former editor-in-chief of Caltech Letters. Originally hailing from Devon, England, he came to California in search of sun and earthquakes. He uses satellites to measure tiny motions in the Earth’s crust and large computers to simulate even larger ruptures.
