Research interests
- Critical Care
- Sarcoidosis
Additional Research Interests
Critical Care Research themes:
- Mitochondrial mechanisms of organ failure during sepsis
- Biomarkers for the early detection of sepsis in the hospital setting; particularly the monocyte distribution width (MDW), FDA approved (2020) for the detection of sepsis in adults admitted to the Emergency Department
Sarcoidosis Research themes:
- Genomic studies of granulomas to determine disease mechanisms and to identify novel therapeutic targets
- Clinical practice guidelines for the diagnosis and management of sarcoidosis
- We established the first tractable laboratory disease model
Current Research
- We are establishing novel biomarkers for early sepsis detection based on machine learning and employing the electronic medical record in conjunction with the US Government and FDA
- We are investigating novel therapies for COVID-induced acute lung injury
- We are conducting translational research in the field of pulmonary sarcoidosis to elicit disease mechanisms, establish novel biomarkers and to investigate novel therapies.

Cared for me for 20 years. Helped me to feel much better.
Dr Elliott Crouser was the best Dr I have ever been to. He was so thorough explaining my health condition and put me at ease with all the information he gave me and explaining it so I could understand and being respectful and compassionate. He took a lot of time to give so much valuable information. I truly feel blessed to have him for my doctor in the specialty of sarcoidoses.

Dr. Crouser is a wonderful doctor. I feel well cared for, he has helped keep me in good health despite the issues I have, and always makes sure that any questions I have are answered.
He is one of the greatest providers I've ever had. Very caring, helpful, respectful of my wants, needs and concerns. I look up to him in the highest regards.
I like that he is so thorough and knowledgeable, and doesn't want to jump right into prescribing medication for my condition. We were able to discuss a treatment plan that we were both happy with.
