The research focus of Boris Prilutsky's laboratory is Neural Control and Biomechanics of Movement. They study how the nervous system controls hundreds of muscles and kinematic degrees of freedom of the body to produce purposeful motor behaviors and how the neural control of motor behaviors is affected by neural and musculoskeletal injuries.

The major research focus of my research is on biomechanics and motor control of locomotion and reaching movements in normal as well as in neurological and musculoskeletal pathological conditions. In particular, we study the mechanisms of sensorimotor adaptation to novel motor task requirements caused by visual impairament, peripheral nerve or spinal cord injury, and amputation. We also investigate how motor practice and sensory information affect selections of adaptive motor strategies.

I am an evolutionary biologist broadly interested in the evolution of complex life. My Ph.D. training focused on the evolutionary stability of cooperation in the legume-rhizorium symbiosis. Here I developed new experimental methods to study how among-organism genetic conflict arises and can be mitigated. A similar evolutionary tension lies at the heart of all key events in the origin of complex life, termed the ‘Major Transitions in Evolution’: namely, how do new organisms arise and evolve to be more complex without succumbing to within-organism conflict? Studying the early evolution of multicellular organisms has been particularly difficult because these transitions occurred deep in the past, and transitional forms have largely lost to extinction. As a postdoc, I circumvented this constraint by creating a new approach to study the evolution of multicellularity: we evolved it de novo. Since founding my own research group at Georgia Tech in 2014, I have combined this approach with mathematical modeling and synthetic biology to examine how simple clumps of cells evolve into multicellular organisms. Our research has shown how classical constraints in the origin of multicellularity — e.g., the origin of life cycles, multicellular development, cellular differentiation, and cellular interdependence — can be solved by Darwinian evolution. At home, I raise two kids on a hobby farm (really just a big garden) with bees, chickens, rabbits, goats, a dog, and lots of edible plants.

Major transitions in evolution (mainly multicellularity). Spatial dynamics of microbial social interactions. Bet hedging. Life cycle evolution. Origin of multicellular development. The transition to multicellularity was critical for the evolution of of large, complex organisms. However, little is known about how early multicellular organisms arise from unicellular ancestors, or how these relatively simple clusters of cells evolve greater complexity. We address both of these issues using experimental evolution, creating new multicellular life in a test tube. Using these model systems (and a good bit of mathematical / computational modeling), my lab explores the origin of multicellular development, cellular division of labor, and mechanisms to prevent cell-level evolution from eroding multicellular complexity. Major transitions in evolution (e.g. multicellularity) are a special case of a more general phenomenon: social evolution. Through collaborations with Brian Hammer (GT Biology), Peter Yunker (GT Physics), and Joshua Weitz (GT Biology), our group examines the spatial dynamics of microbial ecology and evolution.

Additional Research
Current research is directed at understanding the origin and evolution of RNA assemblies and activities that gave rise to RNA-based genetic and metabolic systems, and the interaction of a bacterial RNA-binding protein Hfq that is crucial for the regulation of gene expression by short regulatory RNAs. The first research area is examining the assembly and activities of RNAunder plausible early earth conditions ( e.g. anoxic environment, freeze-thaw cycles of aqueous solutions). We have shown that Fe2+can replace Mg2+and enhance ribozyme function under anoxic conditions. Fe2+was abundant on early earth and may have enhanced RNA activities in an anoxic environments. Freeze-thaw cycles can also promote RNA assembly under conditions where degradation is minimized. The second area of research is investigating the mechanism of the Hfq protein. Hfq is a bacterial RNA-binding protein that facilitates the hybridization of short non-coding regulatory RNAs (sRNA)to their target regions on specific mRNAs. sRNAs are important elements in the regulation of gene expression for bacteria.Hfq is highly conserved among bacterial phyla and has been shown to be a virulence factor in several bacterial species. The interactions of wild type and mutant Hfq proteins with various RNAs are examined using biochemical/ biophysical methods such as the electrophoresis mobility shift assay, fluorescence spectroscopy, and mass spectrometry.

The work in this laboratory is focused on mechanisms underlying motor coordination in mammalian systems. These mechanisms are to be found in the structure and dynamic properties of the musculoskeletal system as well as in the organization of neuronal circuits in the central nervous system. Our work concerns the interactions between the musculoskeletal system and spinal cord that give rise to normal and abnormal movement and posture, and in the manner in which central pattern-generating networks are modified for specific motor tasks. Our studies have applications in several movement disorders, including spinal cord injury. The experimental approaches span a number of levels, from mechanical studies of isolated muscle cells to kinematic measurements of natural behavior in quadrupeds.

We use a combination of molecular, cellular, immunohistochemical, electrophysiological, genetic and behavioral approaches to understand how the nervous system receives, transmits and interprets various stimuli to induce physiological and behavioral responses. We are particularly interested in the basic mechanisms underlying somatosensation, including pain, itch and mechanical sensations. Somatosensation is initiated by the activation of the primary sensory neurons in dorsal root ganglia and trigeminal ganglia. We have discovered the molecular identity of itch-sensing neurons in the peripheral and provided novel insights into the mechanisms of itch sensation (Han et.al. 2013 Nature Neuroscience). We are currently investigating how chronic itch associated with cutaneous or systemic disorders is initiated and transmitted. We are also interested in the sensory innervation in the respiratory system. Chronic respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD) are leading causes of illness and significant public health burdens. We recently identified a subset of vagal sensory neurons mediating bronchoconstriction and airway hyperresponsiveness (Han et. al. 2017 Nature Neuroscience). We are investigating how the sensory innervations in the airway contribute to the pathogenesis of respiratory diseases.
