Sam Trammell

Sam Trammell is an Assistant Professor in the Department of Biomedical Sciences at the University of Copenhagen's Faculty of Health and Medical Sciences. He works within the Grevengoed Group focusing on n-acyl taurines (NATs) and Fibroblast growth factor 21 (FGF21) research.

His educational background includes a PhD in Genetics from the University of Iowa (2016) and a B.Sc. in Genetics from the University of Wisconsin-Madison (2009).

Dr. Trammell's research focuses on two primary areas:

• N-acyl taurines (NATs): Investigating these amphiphilic lipids as endogenously produced detergents, their role in cell signaling through GPR119, fat absorption, and how their concentration increases with dietary fish oil to levels comparable to bile acids
• Appetite regulation: Studying Fibroblast growth factor 21 (FGF21) as a macronutrient responsive hepatokine that regulates lipid metabolism and macronutrient preference

His recent publications demonstrate expertise in metabolomics, mass spectrometry, and lipid metabolism, with particular emphasis on bile acids, hormone secretagogues, and molecular trafficking mechanisms.

Scientific awards and honors include:

• 2018: Marion Dave Francis Innovator Award from the University of Iowa
• 2017: University of Iowa Graduate Dean's Distinguished Dissertation Prize for "Novel NAD+ Metabolomic Technologies and their Applications to Nicotinamide Riboside Interventions"
• 2012-2013: NSF grant MCB-0822581 and NIH Pre-Doctoral Training Program in Genetics T32 grant GM008629

Dr. Trammell has received significant attention for his research, with publications being picked up by multiple news outlets, blogged about, and shared across social media platforms including X (formerly Twitter) and Facebook. His work has garnered considerable attention in academic circles with numerous readers on Mendeley.

His laboratory work utilizes advanced metabolomics techniques to investigate the relationship between small molecule metabolites and hormonal regulation, particularly focusing on how dietary components influence metabolic pathways.
