Following his undergraduate studies at Sheffield Hallam University, and MSc courses in the universities of Leeds and Sheffield Hallam, he completed a DPhil in Microvascular Physiology at the University of Nottingham, joining Hallam in 2013. Markos has extensive experience in the design, development and implementation of lifestyle interventions aiming to improve physiological and clinical outcomes for pre-clinical and clinical populations. He currently leads Lifestyle, Exercise and Nutrition Improvement (LENI) Research Group.
Markos is a fellow of Higher Education Academy (having completed a PGCE in Higher Education) and a member of the Physiological Society. He is also the lead of the U.K. Chapter for the International Union of Angiology Youth Committee. He has been invited to present his work and chair symposia in many international conferences (such as the 28th World Congress of the International Union of Angiology in Beijing, China in 2018 and FEPS 2019 Meeting of the Federation of European Physiological Societies in Bologna, Italy), having also delivered invited seminars and workshops both in the UK and overseas.
His group is currently investigating the effect of lifestyle interventions in the cardiovascular function of clinical and healthy-but-older populations. For example, they have been exploring how exercise can improve endothelial function in patients with chronic venous insufficiency and venous ulceration and reverse the ageing-affected microcirculation in older populations (FISCU II; funded by NIHR – Research for Patient Benefit Programme) and the effect of e-cigarettes in the micro- and macro-vascular physiology of smokers (ISME-NRT; funded by Heart Research UK).
Of particular interest to Markos and his group is the exploration of the effects of regional (e.g., Nordic, Mediterranean) and novelty (e.g., vegan, kefir-based) diets in younger and older groups. This series of projects is being undertaken in collaboration with other U.K. (e.g., Universities of Lincoln and Sheffield) and European (e.g., Aristotle University of Thessaloniki, University of Lille) universities.
Markos is also quite passionate about the reduction of non-communicable diseases in Black, Asian and Ethnic Minority (BAME) populations, and is currently leading a network of distinguished academics, BAME organisations and public health organisations and city councils, aiming to address the disparities faced by this population. Finally, another area of interest for Markos, is the predictive role of heamatological markers in the disease-outcome of patients with rectal cancer as well as the effect of cancer disease in the patients’ cardiopulmonary and microcirculatory function.
Research of Markos and his team is primarily focused on the investigation the effect of lifestyle interventions in the cardiovascular function of clinical and high-risk populations. Current and recently-completed projects include:
a) exercise-based interventions (for people with Systemic Sclerosis - led by Dr Alexandros Mitropoulos; for women with Polycystic Ovary Syndrome – led by Miss Amie Woodward; for people with Venous Leg Ulcers – led by Dr Klonizakis and managed by Miss McIntosh; for older people using aquatic-based exercise regimes – managed by Miss Hunt)
b) regional and novelty diet-based interventions (e.g., kefir-based diet, Mediterranean diet, New Nordic diet, vegan diet and green tea)
c) smoking cessation (involving the assessment of cardiovascular effects of electronic cigarettes for people making a stop smoking attempt).
Recently-funded research projects in which Markos collaborated and led include:
• “Exploring the feasibility of implementing a home-based exercise training and compression hosiery intervention in patients with venous ulceration (FISCU-II)” (funded by the NIHR-RfPB programme).
• “Impact on Cardiovascular Function in Smokers Making a Quit Attempt Using E-cigarettes Compared with Smokers Making a Quit Attempt with Prescription Nicotine Replacement Therapy (ISME-NRT)” (funded by Heart Research UK – Translational Grant). • "Stealth Marketing: Promoting Environmental Sustainability in the Workplace to Increase Employees’ Physical Activity" – (funded by Cancer Research UK Population Research Committee - BUPA Foundation Fund - Innovation Grant).
• "The Waiting Game: Promoting Physical Activity and Cancer Prevention at Public Bus Stops" – (funded by Cancer Research UK Population Research Committee - BUPA Foundation Fund - Innovation Grant).
• “Exploring the Feasibility of Implementing a Supervised Exercise Training and Compression Hosiery Intervention in Patients with Venous Ulceration (FISCU)” (funded by the NIHR-RfPB programme). Markos has collaborated extensively with academics and NHS healthcare professionals. Previous and current collaborations in the academic sector include King’s College London, Brunel University and Universities of Newcastle, Northumbria, Stirling, Sheffield, Nottingham and Lincoln (in the UK), Alabama (USA), Athens and Thessaloniki (Greece), Angiers (France), Lille (France), Plovdiv (Bulgaria) and Frankfurt (Germany). As far as the healthcare sector, he has worked in partnership with the Southern Derbyshire Acute Hospitals NHS Trust, the Sheffield NHS Hospitals Trust, the Leicester Teaching Hospitals NHS Trust, the East and North Herftordshire NHS Trust and the Hillingdon Hospitals NHS Foundation Trust amongst others.

Markos is an editor in the Journal of Pharmacological and Toxicological Methods (since 2011), Clinical Hemorheology and Microcirculation (since 2014) and a guest editor for Frontiers of Physiology (since 2018). He has completed reviews for Microvascular Research, Journal of Pharmacological and Toxicological Methods, Skin Pharmacology and Physiology, Quality in Primary Care, Current Vascular Pharmacology, Acta Physiologica, Inflammation Research and Microcirculation.
He has also acted as an external moderator for the University of Wales between 2012-2016 and he is a currently an international advisor for the Factorial4VLU trial, a study targeting people with Venous Leg Ulcers, funded by the Health Research Council of New Zealand and hosted by the University of Auckland.
Markos is the Director of Studies for Miss Aime Woodward (who is exploring the effects of exercise on women with Polycystic Ovary Syndrome) and a 2nd supervisor for Mr Tom Parkington (who is exploring lower-body resistance exercise in people with Peripheral Arterial Disease). He has led the supervisory team for two MD and two PhD students in the past.
Markos has given provided expert opinions on the effects of pregnancy on exercise performance (BBC Sport, "The Washington Post" newspaper), on nutrition ("The Sun" newspaper) as well as on the physiological effects of smoking cessation ("Sheffield Star" newspaper, BBC Radio, Hallam FM). His articles on "The Conversation" have been reprinted in many national and international media, while he has written articles published in "The Independent" newspaper.
Recent work by Markos and his colleagues on the effects of the Mediterranean Diet in the vascular function of older, sedentary people has been featured in regional (Yorkshire and Lincolnshire), national and international (Greece, USA and Australia) media, with interviews being given to the "Fitness" magazine, medical research websites and blogs, and the BBC regional radio stations.
