Exploring healthy infant brain development

The Howell Lab is a group of Virginia Tech scientists working at the Fralin Biomedical Research Institute in Roanoke, VA. We are dedicated to improving mother-infant health outcomes for our community by exploring the factors that influence healthy infant brain and behavioral development. We help families in our community through scientific research and provide a welcoming environment for our research participants.

Current Study: Analyzing the Effects of COVID-19 on Pregnant Women and New Mothers

Scientists at the MIND Lab are asking pregnant women and moms who have given birth within the last six months to provide input about their experiences amid the COVID-19 pandemic. The 20-25 minute questionnaire will ask study participants to answer questions about their experiences, thoughts, and feelings related to the pandemic. Participants will also complete a brief personality survey and a short task to help us learn how pregnant women and new moms value the future in the context of COVID-19.
