Sarah Zeichner, Graphics Director
Sarah Zeichner is a PhD student in geochemistry, working to better understand the origin of life through her research. When she is not in the lab, she can be found running in the San Gabriel mountains, experimenting with new recipes, creating art, and gardening.
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.
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.
Annika Dugad, Website Design and Management
Annika is a graduate student in physics interested in quantum information and gravity. She spent most of her life in Illinois, where she obtained her bachelor's degrees and developed a fondness for cornfields. In her spare time, she enjoys walking to the nearest bubble tea shop and listening to music.
