Research in David Lab:

The NEIL family of DNA glycosylases are critical enzymes to maintaining the integrity of the genome. They initiate the base excision repair (BER) pathway by cleaving the N-glycosidic bond between the oxidatively damaged base and the sugar. NEIL1 and NEIL3 have a unique ability to excise a wide variety of substrates and remove lesions from alternative DNA contexts. Because of these abilities, I am currently evaluating the ability of NEIL1 and NEIL3 to excise oxidative base damage from G-quadruplex structures. G-quadruplexes DNA structures that occur in sequences that contain three or four adjacent guanines, which can Hoogsteen hydrogen-bond together to from a G-quartet. These G-quartets will stack together with a central K+ or Na+ ion to stabilize the structure in a variety of conformations. What makes the G-quadruples so notable is their location in the promoter sequences of many oncogenes and BER glycosylases, NEIL1 and NEIL3, and they have been implicated in down- or up-regulating gene transcription. Additionally, due to their high G content, G-quadruplexes are prime spots for oxidative damage necessitating repair by the BER pathway. NEIL’s ability to cleave from such structures suggest a dynamic relationship between DNA repair and gene regulation.

Previous Research Experience:

I previously worked as a Research Coordinator for the NorthShore University Health System’s Division of Urogynecology, where I studied the factors that impact patient persistence with urological medication and the relationship between different Urogynecological surgeries and their post-operative results, in addition to managing ongoing clinical trials.  In addition to my research work, I am passionate about science communication and accessibility and helping those with rare genetic diseases. I hope to one day have a career with a biotechnology company focused on therapeutics for individuals with rare genetic diseases.

  • Dogs can detect Parkinson’s years before symptoms—with 98% accuracy July 16, 2025
    Dogs trained to detect Parkinson’s disease using scent have shown remarkable accuracy in new research. In a double-blind trial, they identified skin swabs from people with Parkinson’s with up to 80% sensitivity and 98% specificity, even when other health conditions were present. The findings offer hope for a simple, non-invasive diagnostic method using biomarkers that […]
  • This laser implosion just created a magnetic field like a neutron star July 16, 2025
    A powerful new technique harnesses swirling plasma inside laser-blasted microtubes to produce record-breaking magnetic fields—rivaling those near neutron stars—all within a compact laboratory setup. This innovation promises to transform astrophysics, quantum research, and fusion energy experiments by unleashing megatesla-level forces using nothing more than targeted laser pulses and clever engineering.
  • Scholars just solved a 130-year literary mystery—and it all hinged on one word July 16, 2025
    After baffling scholars for over a century, Cambridge researchers have reinterpreted the long-lost Song of Wade, revealing it to be a chivalric romance rather than a monster-filled myth. The twist came when “elves” in a medieval sermon were correctly identified as “wolves,” dramatically altering the legend’s tone and context.
  • 1,000-year-old health hacks are trending—and backed by science July 16, 2025
    Medieval medicine is undergoing a reputation makeover. New research reveals that far from being stuck in superstition, early Europeans actively explored healing practices based on nature, observation, and practical experience—some of which uncannily echo today’s wellness trends on TikTok.
  • The secret motor protein that slams leaf pores shut—and saves crops July 16, 2025
    Scientists have discovered that a protein once thought to be just a cellular "courier" actually helps plants survive drought. This motor protein, myosin XI, plays a critical role in helping leaves close their pores to conserve water. When it's missing, plants lose water faster, respond poorly to drought, and activate fewer protective systems. The finding […]
