The Arthur C. Guyton Award Fund was established in 1993 from an anonymous donation to support an independent investigator who holds an academic rank no higher than assistant professor and is pursuing research that utilizes quantitative and integrative approaches and feedback control system theory for the study of physiological functions. One award is presented annually to an individual demonstrating outstanding promise based on their research program. The applicant must be a regular APS member in good standing for a minimum of two consecutive years at the time of application. U.S. residency is not required. Applicants must also hold a rank no higher than assistant professor or equivalent. The description of the current and pending research program, highlighting its relevance to feedback control system theory for the study of physiological functions and its use of quantitative and integrative approaches; and justification of how and why the research program meets the intent of the award must be provided. A letter of recommendation from the department chair administrator, administrator or mentor and at least one letter of support discussing the applicant's research program are also required.
