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.

  • 'Low-sugar' vaccine can provide broad immunity against coronavirus variants March 25, 2025
    Early animal studies show that a single vaccine could protect the recipient from different variants of the coronaviruses that cause COVID-19, the flu and the common cold. In addition to creating antibodies that target a specific region of the spike protein that doesn't mutate, the vaccine removes the sugar coat from the virus that allows […]
  • Fluorescent caves could explain how life persists in extraterrestrial environments March 25, 2025
    Deep below the Earth's surface, rock and mineral formations lay hidden with a secret brilliance. Under a black light, the chemicals fossilized within shine in brilliant hues of pink, blue and green. Scientists are using these fluorescent features to understand how the caves formed and the conditions for supporting life in extreme, and even extraterrestrial, […]
  • Hydrophilic coating makes for unflappable golf balls March 25, 2025
    The condition of the grass on a golf course can drastically skew the chances of a winning putt regardless of a player's skill. Now, a coating that soaks up water molecules could slow the roll of a golf ball on a lightning-fast, dry course and speed it up on a sluggish, wet course without interfering […]
  • New Evidence Links Microplastics with Chronic Disease March 25, 2025
    Tiny fragments of plastic have become ubiquitous in our environment and our bodies. Higher exposure to these microplastics, which can be inadvertently consumed or inhaled, is associated with a heightened prevalence of chronic noncommunicable diseases, according to new research.
  • These electronics-free robots can walk right off the 3D-printer March 25, 2025
    This a robot can walk, without electronics, and only with the addition of a cartridge of compressed gas, right off the 3D-printer. It can also be printed in one go, from one material.
