The Team

Dr. Céline Vetter

Dr. Céline Vetter.  Assistant Professor in Integrative Physiology and Director of the Circadian and Sleep Epidemiology Laboratory (CASEL) at the University of Colorado Boulder. You can download my here ( CV_082018). In brief, I received my PhD training in Till Roenneberg’s lab for human chronobiology at the Ludwig-Maximilian-University in Munich, Germany. After implementing work schedules tuned to inter-individual differences in sleep timing in a steel factory in for my postdoctoral work in the Roenneberg Lab, I joined the Channing Lab (Brigham and Women’s Hospital and Harvard Medical School) in Boston to study the associations of shift work and disrupted sleep with chronic disease risk. I joined the faculty there in 2016, and then moved to the University of Colorado Boulder as a tenure-track Assistant Professor in September 2017. As a translational chronobiologist, I use large-scale epidemiological datasets to identify modifiable sleep and circadian risk factors of chronic disease, which can be leveraged in intervention studies to improve health in wellbeing, in day workers, shift workers, as well as in patient populations. I am also a mum of a 5-year girl, a passionate cook, and appreciative of the beautiful things in life (mountains! art! music! books!).

Josef Fritz

Josef Fritz. Postdoctoral Fellow (Biostatistics). Coming from a mathematical background, I first came in touch with clinical research through my interest in statistical programming. Subsequently, I received my PhD training in Biostatistics and Epidemiology at the Department of Medical Statistics and Bioinformatics at the Medical University of Innsbruck, Austria. As a PostDoc, I now want to learn from the new environment and researchers here at CU Boulder, and deepen my expertise in causal reasoning by tackling various research questions around sleep, circadian misalignment and its health consequences, using data of large, established US cohorts (such as the Hispanic Community Health Study or the Nurses’ Health Studies). In my free time, I can often be found outside running, biking, hiking, or skiing. From time to time, I also enjoy playing board and card games with some friends.

Larissa Hunt

Larissa Hunt, B.A. I am currently a master’s student in the lab. I graduated from CU Boulder in December 2018, with a bachelor’s degree in Integrative Physiology. I earned earned summa cum laude honors for my work on an undergraduate honors thesis in the lab examining human light exposure patterns . My current work includes a master’s thesis analyzing daily eating patterns and cardiometabolic health, and I am also helping to organize and implement a pilot study in the lab. I hope to use my research to help better understand different lifestyle modifications individuals can implement to decrease prevalence of chronic diseases such as obesity and diabetes and their related health consequences. In my free time I love to spend my time outdoors hiking and camping, and I like to relax by practicing yoga, reading books, and cooking delicious foods.

Akram Imam

Akram Imam, B.Sc. I am a Master student in the Circadian and Sleep Epidemiology Laboratory. I graduated form the University of Colorado Boulder in the spring of 2018, with an Integrative Physiology major. I am also very much involved in kicking off our first pilot study, and am the team lead for the melatonin assessment team of this study. I wish to continue to grow in this field and use my expertise to help individuals, in what way, I am not entirely sure yet. My hobbies include playing basketball, going on runs, watching T.V., indulging in food and relaxing.

Courtney Collins

Courtney Collins. I am currently an undergraduate studying Integrative Physiology with a certificate in Global Public Health. I pursued an interest in research after studying Biostatistics here at CU. I’m excited to further develop my skills with R and data wrangling! Outside of the lab I enjoy working as a medical assistant, being Vice President of the Biostatistics club, and skiing. I am looking forward to working with my colleagues and dipping my toes into the world of research.

Kaitlin Buck

Kaitlin Buck. I am an undergraduate studying MCD Biology with a certificate in Public Health. In the lab, I am working on a pilot study of a light education intervention on circadian health, as well as another study focused on studying circadian rhythms through dim light melatonin onset assessments. Being a part of this lab has already taught me so much about real-world experiences in research and I look forward to learning much more. After I graduate next spring, I plan to pursue a Masters of Epidemiology to continue my education in this field. Outside of the lab, I am a proud member of Alpha Chi Omega, I enjoy yoga and kickboxing, and I love spending time with family and friends.

Jeremie Kautzmann

Jeremie Kautzmann. I am a student at the University of Colorado Boulder, currently completing the concurrent BA/MS program in Integrative Physiology. In the lab, I am conducting a pilot study which aims to improve circadian health through education on light exposure patterns. In addition to this project, I will be writing a thesis in order to explore my love for research more in depth as well as consolidate my expertise in the domain of circadian rhythms and sleep. I enjoy being in this lab as it offers a way of learning that is different than in the classroom. While the learning curve was very steep at first, it has allowed me to understand just how vital sleep and circadian rhythms are and how it is interwoven in every aspect of our lives. Outside of the lab I enjoy playing soccer, traveling around the world, cooking and especially eating Italian food!

Camille Gannon

 

Camille Gannon. I am currently an Integrative Physiology major, with a certificate in Public Health and plan to graduate in Spring of 2021. After my undergrad I would love to pursue a joint MD and Masters of Public Health program. I enjoy population based research since it connects to my interest in public health. I’m excited for my work in the CASEL lab, including learning more about how misalignments of biological rhythms can influence disease risk. I would love to use my MD some day to help populations put at higher risk for certain diseases, and to be able to address more of the roots of the problem. I am originally from Minnesota but came to the University of Colorado for the mix of academics, outdoors, and skiing. I am on the board for the club ski racing team here at CU, and spend my winters skiing all over the Rocky Mountains. I also enjoy being with friends, yoga, and hiking.
