Introduction
I have a Master in Integrated Physiology in Extreme Conditions and a PhD in Physiology from the University Grenoble Alpes. My research are interested in macro and microvascular adaptations in pathological (diabetes, systemic scleroderma) and extreme environment (frostbite, high altitude hypoxia).

Background. Since vascular responses to hypoxia in both healthy high-altitude natives and chronic mountain sickness (a maladaptive high-altitude pathology characterised by excessive erythrocytosis and the presence of symptoms – CMS) remain unclear, the role of inflammation and oxidative/nitrosative stress on the endothelium-dependent and -independe...

Introduction
Chronic mountain sickness (CMS) is a condition characterized by excessive erythrocytosis in response to chronic hypobaric hypoxia. CMS frequently triggers cardiorespiratory diseases such as pulmonary hypertension and right or left heart failure. Ambient hypoxia might be further amplified night-time by intermittent hypoxia related to sl...
Objective
Systemic Sclerosis (SSc) is a rare, chronic disease characterized by fibrosis, vascular alterations and digital ulcerations. Few drugs have shown efficacy to enhance wound healing of existing SSc-related ulcers. Local delivery of treprostinil, a prostacyclin analogue, may improve wound healing. The present work aimed first at developing a...
Little is known about hemostasis modifications induced by chronic hypoxic exposure in high-altitude residents, especially in those who develop excessive erythrocytosis (EE, i.e. hemoglobin concentration ≥ 21 g·dL-1 in male and ≥ 19 g·dL-1 in female). The aim of this preliminary study was to assess coagulation alterations in highlanders with or with...
The impact of the local inhibition of soluble epoxide hydrolase, which metabolizes vasodilator and anti-inflammatory epoxyeicosanoids, on diabetic skin microvascular dysfunction was assessed. In diabetic db/db mice, basal skin blood flow assessed using laser Doppler imaging was similar to that of control mice, but thermal hyperemia was markedly red...
La cicatrisation est un processus complexe faisant intervenir de nombreux acteurs. En contexte pathologique, ces processus peuvent être altérés, entrainant un retard de cicatrisation et l’augmentation du risque de survenue de complications.Durant cette thèse, par une approche préclinique, nous nous sommes intéressés à la cicatrisation d’ulcères cut...
Introduction:
Hypothermia and frostbite occur when there is a significant decrease in central and peripheral body temperature in individuals exposed to cold windy conditions, often at high altitude or in a mountain environment. Portable hyperbaric chambers increase the barometric pressure and thereby the partial pressure of oxygen inside the chamb...
