Dr. Clarke earned his MI (Biology) in Pharmacology and his Ph.D. in Cell Biology & Biochemistry from Manchester Metropolitan University in conjunction with The Patterson Institute for Cancer Research in Manchester, England. After graduating in 1991 he completed his post-doctoral training in the Department of Cell Biology and Anatomy at Harvard Medical School in Boston, MA and in the Department of Anatomy at the Medical College of Georgia, Augusta, GA.

He then joined the Life Sciences Directorate at NASA/Johnson Space Center as a National Research Council Research Fellow in the Muscle Research Laboratory followed by his appointment as a Senior Staff Scientist in the Division of Space Life Sciences with Universities Space Research Association at NASA/JSC from 1997 until 2002.

Since joining the faculty in 2002 as an Associate Professor in the Department of Health and Human Performance at the University of Houston, Dr. Clarke has taught graduate classes in the Philosophy of Science, Exercise Physiology and Advanced Muscle Physiology as well as being a founding member and Director of the Laboratory for Integrated Physiology (LIP). More recently, he developed a multi-disciplinary Master’s of Science degree in ‘Human Space Exploration Sciences’ that incorporates graduate training not only in space physiology but a integrated blend of bioengineering, architecture and advanced technologies as they apply to the unique challenges of extended human habitation and exploration of space. This degree program, delivered by a unique partnership comprising UH faculty, NASA-JSC Life Sciences Directorate and Wyle Life Sciences personnel was developed in response to NASA’s strategic plan for work-force development.

Since joining the faculty at the University of Houston, Professor Clarke  has served as Chair of the Graduate Research Committee in HHP, Chair of his colleges Graduate Studies Committee, Chair of the UH Senate Faculty Affairs Committee and most recently as President of the University of Houston Faculty Senate. After stepping down from the UH Faculty Senate he served as Chair of the UH System Intellectual Property Committee.

Research Interests

Muscle physiology, muscle adaptation to mechanical loading, cellular basis of muscle function in health and disease. (Note: Dr. Clarke currently serves as Associate Provost for Faculty Development and Faculty Affairs)
