Personal Information

• Born in Dunedin, New Zealand

• Currently living in Boulder, Colorado


Research Interests

• Variability in human movement

• Motor unit discharge behavior in voluntary contractions

• Neural mechanisms in muscle fatigue


Current Research Projects

• Force Fluctuations During Steady Contractions (Jordan, Jesunathadas, Sarchet). To characterize the force fluctuations during steady submaximal contractions performed by young and old adults.

• Presynaptic Inhibition During Fatiguing Contractions (Baudry, Jordan). To compare the level of presynaptic inhibition during the force and position tasks

• Afferent Input and Load Compliance (Barry, Jordan, Taylor). To assess the influence of load compliance on the afferent feedback delivered to motor neurons.

• Fatigue-Related Modulation of Motor Unit Discharge Rate (Rudroff, Jordan, Matthews). To characterize the effect of load type on the decline in motor unit discharge when the arm is placed in different positions.
