Christian Aalkjær

Christian Aalkjær is a Professor in the Department of Biomedicine at Aarhus University, Denmark. His research is centered on vascular and cardiovascular physiology, with a focus on hypertension, blood vessel function, and ion transport mechanisms. He has led major interdisciplinary projects, including the Danish Cardiovascular Giraffe Research Programme, investigating extreme physiological adaptations in giraffes to inform human cardiovascular disease.

Research Interests:

• Physiology of resistance arteries and vascular tone
• Intracellular pH and ion transport (NBCn1, V-ATPase)
• Hypertension and cardiovascular remodeling
• Smooth muscle cell function
• Acid-base balance and water-salt metabolism
• Comparative physiology using giraffe models

His recent publications (2023–2025) reflect a continued focus on vascular reactivity, small artery structure-function relationships, and molecular mechanisms in hypertension. Articles span topics from prorenin effects on mesenteric arteries to genetic causes of arrhythmia syndromes.

Scientific Engagement:

• Active contributor to peer-reviewed journals such as Acta Physiologica, FASEB Journal, and Heart Rhythm
• Frequent invited speaker and lecturer on vascular physiology
• Public science communicator through media appearances on giraffe physiology and hypertension

Advising and Research Leadership:
While specific students are not listed, Aalkjær has supervised academic theses and mentored early-career researchers. He has been a project manager on major grants, including the DaGIR programme, and has secured long-term funding for cardiovascular research. He leads a research team focused on vascular mechanisms and collaborates extensively across disciplines.

Laboratory and Research Environment:
Based in the Skou Building at Aarhus University, his lab investigates vascular function using isolated vessel myography, molecular techniques, and in vivo models. The research environment emphasizes translational physiology, integrating basic science with clinical insights.
