Education: B.S. in Biochemistry and Molecular Biology, University of California-Davis, 2022

From: Hangzhou, China

Joined David Lab: June 2022

Outside of lab: I enjoy watching sports, such as F1 and basketball, and travelling!

Research in the lab: Although much of the research in the David lab focuses on MUTYH and its ability to recognize and repair OG:A mismatches, we are also curious in its role beyond identifying such lesions. MUTYH has shown to mediate cytotoxicity with various chemotherapeutics and UV light. These MUTYH-dependent sensitivities in the cell may also vary depending on the mutant variants of MUTYH. My project involves using both in vitro and cell-based assays to better understand the molecular basis behind this process.

Previous Research Experience: During my time at Davis, I worked in the Niño Lab studying honey bees. I was involved in three different projects involving a mixture of lab and field work. The main goals of these projects were to see if we could increase honey bee health and longevity to better support beekeeper’s needs or determine bee stocks that are more suitable in California’s Central Valley Mediterranean climate. I also joined the David Lab and worked with Melody on synthesizing transition state that are incorporated in oligonucleotides to serve as inhibitors of base excision repair glycosylases.

  • Goodbye colonoscopy? Simple stool test detects 90% of colorectal cancers September 18, 2025
    Scientists at the University of Geneva have created the first detailed catalogue of gut bacteria at the subspecies level, unlocking powerful new ways to detect colorectal cancer. By applying machine learning to stool samples, they achieved a 90% detection rate—nearly matching colonoscopies, but with far less cost and discomfort. This breakthrough could revolutionize early cancer […]
  • Rogue DNA rings may be the secret spark driving deadly brain cancer September 18, 2025
    Rogue DNA rings known as ecDNA may hold the key to cracking glioblastoma’s deadly resilience. Emerging before tumors even form, they could offer scientists a crucial early-warning system and a chance to intervene before the disease becomes untreatable.
  • Harvard’s salt trick could turn billions of tons of hair into eco-friendly materials September 18, 2025
    Scientists at Harvard have discovered how salts like lithium bromide break down tough proteins such as keratin—not by attacking the proteins directly, but by altering the surrounding water structure. This breakthrough opens the door to a cleaner, more sustainable way to recycle wool, feathers, and hair into valuable materials, potentially replacing plastics and fueling new […]
  • Scientists crack a 50-year solar mystery with a scorching discovery September 17, 2025
    Scientists from the University of St Andrews have discovered that ions in solar flares can reach scorching temperatures more than 60 million degrees—6.5 times hotter than previously believed. This breakthrough challenges decades of assumptions in solar physics and offers a surprising solution to a 50-year-old puzzle about why flare spectral lines appear broader than expected.
  • Rare Einstein cross with extra image reveals hidden dark matter September 17, 2025
    A strange “Einstein Cross” with an extra, impossible fifth image has revealed the hidden presence of a massive dark matter halo. An international team of astronomers, including Rutgers scientists, used powerful radio telescopes and computer modeling to confirm the invisible structure’s existence. This rare cosmic lens not only magnifies a distant galaxy but also opens […]
