Research Assistant | B.S. in Biology, UC Irvine
I graduated from the University of California, Irvine, in 2024 with a B.S. in Biology. During that time, I worked in Dr. Marcus Seldin's lab, researching the role of novel proteins in cross-tissue interactions using systems genetics approaches. My interests are in epigenomics and proteomics. At Carnegie Science, I hope to grow as a researcher and make valuable contributions to addressing biological challenges.
Summer Intern | B.S in Neuroscience, Saint Louis University
I graduated from Saint Louis University in 2025 with a B.S in neuroscience. I am excited to work with plants and I am ready to learn more about genetics and cloning. I want to improve my research skills so that one day I can perform my own research.
Summer Intern | Highschool Student
My name is Daniel Wang. I am a rising senior in high school. I am very excited and enthusiastic to be working as an intern at Carnegie because I would love to learn more about science and its real-life applications. Also, I am fascinated by Dr. Xu's recent research about plant protein homologies. Finally, I love to grow fruit trees; I have 17 fruit trees in my backyard.
Summer Intern | Cupertino Highschool Student
Chris is an aspiring high school student with a passion for biology, particularly in the fields of immunology and nutrition. He values every opportunity to learn, and brings curiosity and dedication to every project. Chris is committed to building a strong foundation of scientific knowledge and is always eager to work collaboratively. Outside of academics, he enjoys skiing, mountain biking, and wakeboarding.
Summer Intern | Mission San Jose High School
Hi, my name is Connie Li and I am a rising senior at Mission San Jose High School. I am fascinated by biological sciences and have previously done research in biochemistry. This summer, I'll be working in Dr. Xu's lab, and I’m really looking forward to learning and growing through this experience. Outside of research, I enjoy playing volleyball, discovering new matcha spots, taking naps, and listening to music.
