• Effects of hormones such as estrogen on muscle damage, repair, strength and hypertrophy mechanisms using both animal and human models. This type of research has particular application health and muscle function in post-menopausal women.
• I also have research interests in evaluation of the potential for various therapeutic modalities to influence muscle repair and recovery from unaccustomed exercise
