Using non-linear dynamics, computational models for neurons that replicate the sleeping and waking states of the brain are being undertaken. Switching between these states will be modulated by the circadian drive. The models will consider both hemispheres of the brain to study both bihemispheric sleep and unihemispheric sleep. Results of the study will have implications for astronauts maintain regular sleep/wake cycles in long duration space flights. This study forms the basis for Tera Glazes Ph.D. dissertation.

Stellar encounters soon after stars form shape the dynamics of young star clusters and the variety of planetary systems stars form. Stars form in small groups from dense molecular cores and as they emerge, repeated interactions will result in an equilibrium distribution of speeds as well as the truncation or stripping of circumstellar disks. High resolution infrared spectroscopy of 32 very young objects in the nearby Rho Oph cloud has revealed the possible collapse or expansion of subclusters prior to achieving equilibrium. This study forms the basis of Tim Sullivans Ph.D. dissertation and a paper describing this project will be submitted early in 2019. Other direct participants included Professor Erika Gibb who provided expertise in chemical models and reduction techniques and graduate and undergraduate students Chemeda Ejeta and Lindsey Rodgers, respectively, who assisted with the bulk of data reduction for analysis.
