Dr. Raj Logan PhD

My lab studies gene regulatory networks and cell physiological mechanisms that direct animal development.  We use the fruit fly, Drosophila melanogaster, as a model organism.  Our multidisciplinary work is composed of two research programs and uses methods from genetics, cell biology, biochemistry, molecular biology, and bioinformatics. 

• Developmental Dynamics-The questions that drive our developmental dynamics research projects aim to determine the key components of Drosophila matrisome that direct tubulogenesis in the embryo.  Model tubular organs studied include (i) the embryonic salivary gland, (ii) trachea, and (iii) the heart.
• Integrative Systems Biology-The questions that motivate our systems biology initiative explore the effects of exercise physiology on stem cell dynamics.  We ask how exercise affects stem cell health by focusing on the cellular and extracellular mechanisms that calibrate stem cell homeostasis in response to systemic training adaptations.
