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.

  • Ever wonder why some meteor showers are so unpredictable? April 16, 2025
    Why do comets and their meteoroid streams weave in and out of Earth's orbit and their orbits disperse over time? Researchers show that this is not due to the random pull of the planets, but rather the kick they receive from a moving Sun.
  • RoboBee comes in for a landing April 16, 2025
    A recently created RoboBee is now outfitted with its most reliable landing gear to date, inspired by one of nature's most graceful landers: the crane fly. The team has given their flying robot a set of long, jointed legs that help ease its transition from air to ground. The robot has also received an updated […]
  • Sunscreen, clothes and caves may have helped Homo sapiens survive 41,000 years ago April 16, 2025
    A study suggests that Homo sapiens may have benefited from the use of ochre and tailored clothing during a period of increased UV light 41,000 years ago, during the Laschamps excursion.
  • 'Big surprise': Astronomers find planet in perpendicular orbit around pair of stars April 16, 2025
    Astronomers have found a planet that orbits at an angle of 90 degrees around a rare pair of peculiar stars. This is the first time we have strong evidence for one of these 'polar planets' orbiting a stellar pair.
  • Crystal clues on Mars point to watery and possibly life-supporting past April 16, 2025
    A new study analyzing data from NASA's Perseverance rover has uncovered compelling evidence of multiple mineral-forming events just beneath the Martian surface -- findings that bring scientists one step closer to answering the profound question: Did life ever exist on Mars?
