WELCOME TO THE CHAN LAB
AT JUNIATA COLLEGE
In the lab, we use genetic, cellular, and behavioral techniques to dissect animal physiology and behavior.
Environmental Factors ---> ANIMALS ---> animal response and adaptation
The lab is interested in understanding the behavioral adaptations and cellular modifications an organism makes in response to environmental challenges. Our environmental surroundings are filled with factors such as toxins, pathogens, heat or disease states that can alter animal physiology and behavior. An animal must appropriately respond and adapt to these environmental factors to survive. We study how animals respond and adapt by using the model organism C. elegans, a roundworm. In particular, we are interested in the adaptability of the nervous system, which may include modifications such as recruiting new neurons, changing neuronal connectivity, or altering the strength of neuronal communication. The interactions of other organs (muscle, skin, intestine) in response to environmental factors will also be explored. Because C. elegans can be studied genetically, cellularly, and behaviorally with fast and manageable methodology, the experiments using worms will help us understand how other animals learn and make the appropriate adaptations to the environment.
