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.

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.

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).

Do you have any of your baby teeth or are you a parent who has kept your child's baby teeth? Are you a young adult or a parent of a child age 25 or under? Did you know scientists can learn all about different medications, foods, and environmental exposures in a child's early life from their teeth? You may be able to take part in a research study to learn what factors increase children's risk of developing EoE (eosinophilic esophagitis)! We are looking for children and young adults (age 0-25) with or without EoE to volunteer. Compensation will be provided.

How does your baby's environment affect their brain? A child's brain grows quickly during pregnancy and infancy. If you are pregnant in your 2nd or 3rd trimester, you may be eligible to participate in a research study to find out how your environment affects your baby's brain development. Compensation provided.

Does your child or teen have a history of wheezing or asthma? Your child may be eligible to participate in a registry that will allow us to understand how wheezing and asthma change over time in kids and teens. Compensation provided for in-person study visits. We will also be enrolling some children without a history of wheezing or asthma to serve as a comparison group.

Do you ever wonder if there is a connection between oral and gut health and food allergies? Well, so do we! We are trying to enroll pediatric participants in our registry study to determine what the link is and use it to possibly help treat patients in the future.
