Research in David Lab:

DNA is prone to oxidative damage by both exogenous and endogenous sources. DNA damage must be repaired to maintain genomic integrity, and the base excision repair (BER) pathway has evolved to recognize and initiate repair caused by oxidative damage. My projects involve the glycosylases hOGG1 and NEIL 1, 2, and 3. My work with hOGG1 involves synthetic organic chemistry to synthesize potent and specific nucleic acid based inhibitors of the enzyme. It has been previously demonstrated by our lab that certain transition state analogue mimics tightly bind hOGG1’s active site, but it has yet to be demonstrated that these analogues can inhibit the enzyme in a cellular context, which is what my work focuses on. My second project (involving NEILs 1, 2, and 3) involves understanding whether repair of oxidative damage by the NEILs is affected by oxidants such as hydrogen peroxide and potassium bromate in a cellular context.

Previous Research Experience:

As an undergrad, I worked in Dr. James Nowick’s lab for 2.5 years. My first project involved synthesizing fluorescent mimics of the amyloid beta peptide, the aggregation of which has been linked to the incidence of Alzheimer’s disease. My second project involved synthesizing fluorescent mimics of the peptidic antibiotic teixobactin, which shows no detectable resistance. This work led to a publication that details the mechanism by which teixobactin is able to localize to the lipid bilayer of gram-positive bacteria.

  • Megalodon: The broad diet of the megatooth shark May 26, 2025
    Contrary to widespread assumptions, the largest shark that ever lived -- Otodus megalodon -- fed on marine creatures at various levels of the food pyramid and not just the top. Scientists analyzed the zinc content of a large sample of fossilized megalodon teeth, which had been unearthed above all in Sigmaringen and Passau, and compared […]

  • A dental floss that can measure stress May 23, 2025
    Scientists create a floss pick that samples cortisol within saliva as a marker of stress and quantifies it with a built-in electrode. The system uses a polymer casting technology that can be adapted to capture a wide a range of markers, such as estrogen for tracking fertility, or glucose for tracking diabetes. Ease of use […]
  • Why are some rocks on the moon highly magnetic? May 23, 2025
    Scientists may have solved the mystery of why the moon shows ancient signs of magnetism although it has no magnetic field today. An impact, such as from a large asteroid, could have generated a cloud of ionized particles that briefly enveloped the moon and amplified its weak magnetic field.
