Christina Xu ’22 realized she wished to operate in Assistant Professor of Biology Giancarlo Cuadra’s lab before she even started out lessons as a to start with-year student. Xu was a Dana Scholar, and throughout preorientation, Abrar Shamim ’20 told the team he was top about his ordeals performing with Cuadra.

“[Shamim] mentioned he worked in the lab on vaping products and solutions and their consequences on oral health,” claims Xu, a biology significant and general public wellness minor who is headed to the Harvard College of Dental Drugs this drop. “On the first working day of preorientation I knew: That’s the lab I’m going to be in.”

She contacted Cuadra during her 1st semester in Drop 2019 (she graduated a calendar year early), and he invited her to shadow in his lab. She did that right until the pandemic hit and college students have been sent household. When Xu was back on campus in Spring 2021, she was skilled in Cuadra’s lab, and she took in excess of a venture from a pupil who was graduating. 

That project turned “Mechanistic Consequences of E-Liquids on Biofilm Development and Development of Oral Commensal Streptococcal Communities: Outcome of Flavoring Agents,” a paper published in Dentistry Journal last thirty day period. Xu was the lead writer.

“It was my very first paper … I don’t imagine I realized how a lot perform it would be,” she says, noting that she commenced doing the job on the manuscript past November. “Dr. Cuadra’s intention was to have me published in advance of college graduation, so I would not have to get worried about it in dental university, but it came seriously near.”

Xu’s exploration examined how five unique flavors of e-cigarettes affect the oral microbiome. She found that cinnamon and menthol flavors ended up especially harmful, killing the excellent microorganisms necessary for oral wellbeing. The research feels timely specified that the Food and drug administration has introduced that Juul, the moment a leading e-cigarette brand name, need to pull its merchandise from the marketplace, in component thanks to concerns about “potentially dangerous chemical compounds leaching from the company’s proprietary e-liquid pods.”

One of the good reasons Xu selected Harvard for dental faculty is its emphasis on investigate: “Every scholar is required to carry out a analysis undertaking. That is some thing I’ve uncovered is definitely critical, the outside the house-the-classroom finding out,” she states. “It doesn’t have to be just lab work like I did in undergrad. You can do group-primarily based community well being research, which I might be interested in switching into due to the fact that was my minor in college. You can get to perform on a lot more of a scientific side with individual research … Boston has such a large and expansive hospital network that you have a whole lot of alternatives to carry out exploration in any way.”
