Dr Sam Lucas is an integrative physiologist with a primary research interest in brain health; specifically he is interested in how cerebral blood flow is regulated in health and disease, and the resultant impact on brain function (e.g., neurophysiological and psychological/behavioural responses). His broader interests and expertise are in the areas of exercise and environmental physiology, as well as physical activity and health. 


2008 Doctor of Philosophy, University of Otago

2002 Bachelor of Science (Physiology), University of Otago

2001 Bachelor of Physical Education (Honours, 1st Class), University of Otago


Dr Lucas completed his PhD in 2008 at the University of Otago, New Zealand. His thesis investigated the physiological and cognitive consequences of prolonged exercise. Dr Lucas then had 5 years post-doctoral training focused primarily around techniques to measure cerebral perfusion and understanding the integrative mechanisms that regulate cerebral blood flow during stress and how this may be altered in different populations.

He joined SportExR as a Lecturer in March 2013 and also holds an Honorary Lectureship in the Department of Physiology, University of Otago, New Zealand. 


Dr Lucas contributes across all three undergraduate years within the Sport and Exercise Sciences degree programme, teaching fundamental and applied physiology principles in both lecture- and laboratory-based settings.

Modules Dr Lucas contributes to:

1st year: Human Physiology; Physical Activity and Health

2nd year: Exercise Physiology

3rd year: Environmental Physiology; Exercise is Medicine

In addition, he supervisors a number of 3rd year, taught MSc and MRes dissertation projects each year within the School, as well as contributes to other degree programmes across campus (e.g., Biomedical Science BSc).

Dr Lucas is an integrative physiologist whose primary research focus is on the integrative mechanisms that regulate human cerebral blood flow in health and disease. He has a specific interest in how cerebral blood flow is regulated with ageing and during stress (esp. high altitude, thermal, orthostatic, exercise and cognitive) and how this impacts on function (e.g., neurophysiological and psychological/behavioural responses).

Dr Lucas has 15 years of research experience and has developed a broad range of research skills and expertise, which underpins his inter- and multidisciplinary approach to research. To date, Dr Lucas has published 80 peer-reviewed publications, 1 book chapter and 138 conference abstracts. His published work is in leading journals within the field, including papers which have been widely cited (3 publications more than 100 times). Dr Lucas has received awards for work presented at national and international conferences, and has been awarded early career awards in the UK and New Zealand. Graduate students working with him have also won such awards, as well as research grant awards (e.g., Claire Burley: CANTAB Research Grant).

As Principal or co-Investigator, Dr Lucas has been awarded >£800,000 worth of research funding across a range of sources, including research councils, charities, and sporting, government and commercial bodies. Dr Lucas is a key principal investigator involved in establishing the new Centre of Human Brain Health (CHBH) at the University, and recently co-led a successful College Strategic Equipment bid for a functional NIRS system (worth £460,000). In 2015, Dr Lucas obtained significant funding (£110,700) to upgrade the Environmental Chamber within the School, which now operates as a University Facility for which he is the director of. The upgrade of the chamber is the first stage in establishing the Birmingham Environmental Physiology Research and Education Centre, which is a collaborate initiative led by Drs Sam Lucas, Rebekah Lucas and George Balanos to establish a translational research and educational programme that uses mechanistic exercise and environmental physiology to address health needs in the local and global community.

Since arriving at UoB, Dr Lucas has established inter- and multidisciplinary collaborations with clinicians, optical bioengineers/computer scientists, MR physicists/researchers and other physiologists that have resulted in a series of studies and publications that include development and testing of new neuroimaging technology, validation and comparison of different neuroimaging methodologies and analysis approaches, as well as examining brain vascular responses to novel exercise, cognitive and environmental stress. Current projects in the Lucas laboratory are focused on:

  • Investigating age- and disease-related changes to the regulation of brain perfusion and the functional consequences;
  • Multimodal assessment of brain health;
  • Exercise strategies and complementary approaches (e.g., environmental stress, nutrition) that optimise health (esp. brain health).

In addition to this primary research focus, Dr Lucas is involved in numerous projects investigating various aspects of health and performance. He collaborates widely with colleagues in the School, across campus and has a number of long-standing, successful national and international collaborations.
