Ongoing studies currently enrolling participants:


BRIGHTKids Study: This study is a sub-project stemming from the larger birth cohort study, STRONGKids 2 (registered at as NCT03341858; IRB # 13448), which currently follows participants from birth to 7 years. The purpose of the sub-project is to explore outcomes of cognitive development and body composition and their predictors (diet, physical activity, parent characteristics, etc.) in greater detail as these children turn 4 and 5-years-of-age. Specifically, these participants will undergo a body composition scan, a pencil paper test to assess academic achievement, and they will perform several computer-based cognitive tasks while their brain function is being measured. Additionally, parents will complete surveys and a 7-day diet record for their child. Participants will also be asked to wear a physical activity tracker for 7 days. For participation, you must already be enrolled in the STRONGKids 2 study. However, note that the STRONGKids 2 is no longer actively recruiting. IRB #16484

iCONS: This study is for children ages 8 to 10 years to help us learn how nutrition supports eye health and school performance. Children will participate in seven 2-hour visits and take a daily gummy over nine months.  Activities include height, weight, and eye health measurements, reading and math related questions, computer tasks, and parent questionnaires.  You will be paid for your time and effort. IRB #21066.

LiBra: This study is for children ages 7 to 13 years to examine the relationship between diet, physical activity, and cognitive performance. Participation involves 3 visits to both Freer Hall (visits 1 & 2) and the Beckman Institute (visits 2 & 3). Measures will include health behaviors such as diet, weight status, brain imaging, and a blood draw. Compensation will be provided (up to $200). IRB #19811


LUMES Study: Lutein and Multiple Sclerosis Evaluation Study. LUMES is examining the relationship between macular carotenoids, retinal health, and cognition in people with Multiple Sclerosis in adults ages 18-64 years.  IRB #20012

SCOPE Study: This study involves adults ages 45 to 75 years consuming two different supplements on a daily basis for two four week periods. Participant testing will involve completing surveys and computer tasks (over 5 visits of 1.5 to 2.5 hours each) to assess thinking ability and collection of stool samples. Additional information on health history and habitual physical activity and dietary intake. You will be paid for your time and effort. IRB #21839

STARC: This study involves adults ages 18 to 75 years. The Stress, Arterial Health and Cognition (STARC) study investigates the relationships between arterial health, stress reactivity, and cognitive function. Participation involves 1 lab visit (4.5 hours) during which we will assess your artery health, cognition, and fitness. You will receive $75 in Amazon e-gift cards as compensation.
