Biography

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.

Dr Lucas joined the University of Birmingham as a Lecturer in March 2013.

Teaching

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

Research

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 20 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 123 peer-reviewed publications, 3 book chapters and 188 conference abstracts. His published work is in leading journals within the field, including papers that have been widely cited (e.g., 11 publications with >100 citations (3 with >300) and 14 more with >50 citations). 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 >£2 million worth of research funding across a range of sources, including research councils, charities, and sporting, government and commercial bodies. Dr Lucas is principal investigator within the Centre of Human Brain Health (CHBH) at the University and serves on its management committee, and is the director of the Environmental Chamber Facility located within SportExR.

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.
