Are you pregnant? Please take part in our study! You can help us learn more about how pregnancy hormones relate to mood and brain activity. Compensation provided.

Does your child have hearing loss in one ear, or single-sided deafness? If they are under the age of 3, they may be able to receive a cochlear implant as part of a research study to find out if early implantation helps children with single-sided deafness. If they are five, they may be able to help us study differences between children who receive a cochlear implant when they are little, children who do not receive a cochlear implant, and those with typical hearing.

Interested in participating in future research studies? Whether you have had a previous ACL injury or not, you may be able to take part in several research study opportunities. This registry simply collects your contact information and then we will reach out if any study opportunities are available.

We study how the immune system protects against viruses and bacteria without causing excessive harm to organs like the lungs, heart, and kidneys. We need a small amount of blood to study how immune cells ("white blood cells") turn on important proteins when they sense a bacteria or virus nearby.

Are you interested in participating in orthopedic research? Are you otherwise healthy, with no previous history of lower extremity orthopedic injury? If so, you may be able to participate in a research study to determine the gait patterns of an otherwise healthy population.

Up to 30% of individuals who injure their anterior cruciate ligaments (ACL) suffer another ACL injury following reconstruction surgery. Improving function of the hamstrings muscles may reduce the risk of a second ACL injury. This study will determine if a novel rehabilitation tool (local muscle vibration) improves muscle function and landing characteristics (biomechanics) that are linked to ACL injury risk. Compensation is provided.

Have you had ACL reconstruction? You may be able to participate in a research study examining how brain function might change after surgery. Compensation provided.

Do you wonder about your mobility as you age? You may be eligible to participate in a research study investigating age effects on foot-ankle mechanical power interactions with the goal to enhance foot and ankle function in aging and mobility. Compensation provided.

Want to help improve the treatment of people with chronic blood cancers? We are looking for healthy volunteers to take part in a simple blood-draw study. If you are generally healthy and are not taking blood thinners, you may be able to help improve treatment for patients with chronic blood cancers by donating a tablespoon of blood. This study aims to understand why individuals with chronic blood cancers have a high risk of blood clots as compared to healthy individuals, by comparing (1) the ability of blood to clot in a test tube and (2) changes in white blood cells that make them more likely to stick to blood vessels between healthy individuals and individuals with chronic blood cancers.

Have you been infected with COVID-19? Are you a solid organ transplant recipient? Have you or your child received a COVID-19 vaccine or are planning to receive one? If so, you may be eligible to participate in a research study that will assess your immune response to COVID-19 infection or vaccination over a 5 year period. We are looking for children and adults aged 7-95 years, and plan to collect blood every 2-6 months over the study period. (Compensation provided for the first year).
