Chemistry alum’s research indicates potential harm of essential oils

BOONE, N.C. — Lavender and tea tree oils may be causing breast growth in young boys.

J. Tyler Ramsey ’16, an Appalachian State University chemistry major now working at the National Institute of Environmental Health Sciences (NIEHS) — part of the National Institutes of Health, gained worldwide news media attention recently for his research showing this possible link.

Ramsey is a postbaccalaureate Intramural Research Training Award (IRTA) fellow at NIEHS. He was lead researcher for “Steroid Receptor Hormonal Actions of Lavender and Tea Tree Oil Components,” which was presented March 19 at ENDO 2018, the Endocrine Society’s 100th annual meeting in Chicago.

Key chemicals in the common plant-derived oils act as endocrine disruptors, interfering with hormones and their actions in the body, according to a news release from the Endocrine Society.

The study was chosen from 3,000 submitted abstracts and was among 38 selected for a printed research summary for the news media. It became one of just 14 studies selected for presentation at a news conference.

“It’s been a life-changing experience,” said Ramsey, who is originally from Cramerton. He spoke about his Appalachian Experience and how it prepared him for what he’s doing now:

Tell us more about your role at the National Institute of Environmental Health Sciences.

I work in the Reproductive and Developmental Biology laboratory of Dr. Kenneth Korach. My day-to-day work varies. I design and conduct experiments, lead lab meetings, give seminars and write up manuscripts. I’ve seen all aspects of research, which has been very educational.

What aspects of your Appalachian education best prepared you for this opportunity?

I did three years of research with Dr. Jennifer Cecile in the Department of Chemistry and was in the Honors College, which really challenged me because of the 40-page honors thesis I had to write. I appreciated the huge mentorship I received from Dr. Leslie Jones, who was the director of the Honors College at that time. Undergraduate research is very difficult, but it also teaches you well. Having to write my honors thesis was helpful in preparing me for the research manuscripts I write now.

The Honors College seminars helped me, too, and I selected seminars that weren’t science-based: leadership, and narratives in the caring professions. I entered the Honors College as an internal applicant once I was on campus, and I feel the seminars I selected helped me with networking and how to work on teams — there’s a lot of this in the professional world — and also how to build empathy.

Describe your experiences in the Department of Chemistry.

I got a lot of individual attention. The classes were small, and I knew my professors by name and they were mentors to me. That really helped the learning environment. The classes were very difficult. As personable as the faculty are, that doesn’t affect the grade! I got a really good education there as a result. I also did a minor in biology, and I enjoyed those classes as well.

What are your long-term career plans?

I plan to finish my two-year appointment this June at the NIEHS and then go to medical school for oncology. I’ve been accepted to multiple medical schools and plan to matriculate into the Edward Via College of Osteopathic Medicine this July.

What else would you like to say about Appalachian?

I really enjoyed my time there! Besides my work in the chemistry department, I was active with the Ski Team, the INTAPP student organization, the Health Professions Club and was a tutor. I also studied abroad in South Africa with the Department of Biology alongside Dr. Nathan Mowa.

Appalachian was not my first choice, but I’m so glad I ended up there. Once I became a student, I knew it was the place for me.

Chemistry (BS) - Biochemistry

Appalachian now offers a Bachelor of Science degree in chemistry with a concentration is biochemistry. This is the Department of Chemistry's most popular concentration, and it is designed for students who wish to use a chemistry background as preparation for graduate or professional schools such as medical, pharmacy, physician assistant or dental school. Laboratory research opportunities are available with a faculty mentor to further enhance students’ readiness.
