Dr. Kendall studies a range of health conditions, particularly focusing on respiratory infections, hypermobile Ehlers-Danlos syndrome (hEDS), and the effects of inflammation in the brain. He investigates how airborne particles of different sizes affect lung function, which can be pivotal for treating respiratory diseases. In the area of hEDS, he explores genetic factors that contribute to the condition, helping to uncover the underlying biological mechanisms and improve diagnosis and treatment strategies. Additionally, he examines how brain inflammation impacts behavior differently in males and females, shedding light on sex-specific health outcomes.
Key findings
Smaller aerosol particles (1.3 to 1.4 micrometers) penetrate the lungs more effectively than larger particles (6.1 to 10.4 micrometers) or liquid solutions, which is crucial for understanding respiratory infections.
In a cohort of 200 hypermobile Ehlers-Danlos syndrome patients, a specific genetic variant in the KLK15 gene was found in 14 out of 15 kallikrein genes assessed, indicating a significant link to connective tissue issues.
Mice genetically altered to carry the KLK15 gene variant exhibited connective tissue problems, reinforcing the genetic basis for hypermobile Ehlers-Danlos syndrome and opening doors for earlier diagnosis.
Adenosquamous carcinoma of the glottis was successfully treated with laser surgery in an 82-year-old patient, demonstrating a promising approach for a type of throat cancer that is often hard to treat.
The use of a flexible antenna array for breast cancer detection showed potential for better skin contact and accessibility, although interference issues need to be addressed in future designs.

2026
Inhalation toxicology
Boydston JA, Yang HJ, Mazur S, Bohannon JK, Lackemeyer MG +15 more
Plain English This study looked at how different sizes of airborne particles, specifically small- and large-particle aerosols, deposit in the respiratory tracts of hamsters and guinea pigs compared to a common method of delivering drugs through the nose (intranasal bolus). The researchers found that smaller particles (around 1.3 to 1.4 micrometers) were more effectively deposited in the lungs than larger particles (6.1 to 10.4 micrometers) or the intranasal method. This matters because understanding how these particles behave can help in studying infections and diseases, as it shows that using intranasal delivery may not accurately reflect what happens with aerosol exposures.
