Weake Lab

The Weake laboratory study the epigenetic mechanisms that control gene expression from the earliest stages of embryonic development to the oldest phases of adult aging. During early embryogenesis, developmental events and cell growth are exquisitely coordinated with rapid cell divisions to lay out a body plan for the growing animal. Later during aging, neurons in the brain no longer divide and become susceptible to cumulative damage resulting from exposure to stress, and the passage of time itself. Dr. Weake uses the fruitfly (Drosophila melanogaster) as a powerful model system to study aging and development, and provide insight into both cancer and age-associated neurodegenerative disease.

We are actively seeking new graduate students, so if you are interested in finding out more about our research – please contact Dr. Weake (vweake@purdue.edu).
