Mary A. Carskadon [MAC] 2022 Sleep and Circadian Rhythms Summer Research Fellowship
Program of Research
Light is the strongest environmental signal to the internal circadian (biological) clock of humans. Although the biological response to light has been investigated in adults, very little is known about how light influences the circadian clock of young children. The primary goal of this summer's study is to understand how light can advance the timing of the circadian clock of preschool-age children.
What Research Apprentices Do
This summer study involves creating dim light conditions within a child's home for 3 days. On the first and third evening of the in-home assessment the child remains in dim light, and on the second morning the child is exposed to light during the hour before their usual waketime.
Apprentices will carry out multiple facets of data collection including saliva collection, setting up dim light conditions, training subjects, data entry, assisting with light exposure, and entertaining subjects. Data collection will be done in teams, and each team will be assigned to work certain days of the week - not always Monday through Friday, often Saturday and Sunday - in research protocols that involve working unusual schedules (early shifts may start at 5:00 AM and late shifts may end at 12:00 AM).
- Bootcamp: There will be an all-day training on TBD on main campus that apprentices are required to attend. There are no exceptions.
- Summer: The apprenticeship runs from May 9 - August 19. Apprentices are expected to devote the summer entirely to this academic research experience and not have other jobs or take course work.
- Retreat: Each apprentice will complete a presentation based upon library research, presented to the group at the end-of-summer retreat in Estes Park Dates TBD. Additionally, invited scientists in the areas of sleep or circadian rhythms research will give presentations describing their career paths and their scientific research.
Stipend and Other Benefits
Every apprentice will receive $4000. The UROP Assistantship covers $2000, and those who receive the award will be paid an additional $2000 by the lab. Those who do not receive the UROP Assistantship will be paid $4000 directly by the lab. Stipends are subject to taxes and fees, and payments will occur every 2 weeks across the summer starting 2 weeks after the program begins.
- Apprentices are required to submit a UROP Assistantship application by TBD. Any funds not covered by UROP will be covered by the lab.
- Paid travel and lodging for Estes Park retreat.
We are currently accepting applications for the Summer Research Fellowship. We will send an email to all students in IPHY when we open 2022 summer applications
We will be accepting applications until December 22, 2021. Interviews will be held on a rolling basis. The earlier you submit your application, the earlier it will be reviewed by our team.
This research opportunity is open to all CU Boulder undergraduate students. Please send your completed application (see below), resume or CV, and unofficial transcript to firstname.lastname@example.org. Candidates will be interviewed in person. Upon acceptance into the program, apprentices will be required to pass a background check.
