Our lab’s long-term goal is to understand how neural activity both produces memories and protects brain health, while using this knowledge to engineer neural activity to treat brain diseases. Our lab studies how coordinated electrical activity across many neurons represents memories of experiences, how this activity fails in animal models of Alzheimer’s disease, and how engineering neurons to produce this activity has neuroprotective effects and engages the brain’s immune system. Integrating innovative experimental and analytical methods, this research will provide unprecedented insight into how neural activity failures lead to memory impairment and will reveal novel ways to engineer neural activity to repair brain function. Using non-invasive approaches, we translate these discoveries from rodents to humans. These insights could lead to radically new ways to treat diseases that affect memory like Alzheimer’s, for which there are no effective therapies.

Research Interests:

Our work centers on understanding how the brain represents information and intention, and using this knowledge to develop high-performance, robust, and practical assistive devices for people with disabilities and neurological disorders. We take a dynamical systems approach to characterizing the activity of large populations of neurons, combined with rigorous systems engineering (signal processing, machine learning, control theory, real-time system design) to advance the performance of brain-machine interfaces and neuromodulatory devices.

Costas Arvanitis


 

Research Interests:

Therapeutic applications of ultrasound:

Costas Arvanitis’ research investigates the therapeutic applications of ultrasound with an emphasis on brain cancer, and central nervous system disease and disorders. His research is focused on understanding the biological effects of ultrasound and acoustically induced microbubble oscillations (acoustic cavitation) and using them to study complex biological systems, such as the neurovascular network and the tumor microenvironment, with the goal of developing novel therapies for the treatment of cancer and central nervous system diseases and disorders.

Development of novel polymeric biomaterials, regeneration of tendon/ligament, protein delivery for orthopaedic tissue engineering.

The goal of our laboratory is to design polymeric biomaterials for specific orthopaedic applications, including regeneration of tendon/ligament, cartilage and bone. These synthetic and naturally-derived biomaterials are used in conjunction with other biochemical and mechanical stimuli to promote priming of stem cells to express a particular phenotype, as well as deliver biomolecules to promote healing of tissues that have degenerated due to chronic conditions, such as osteoarthritis or overuse injuries.

Research Interests:

Systems biology, computational modeling, redox metabolism and signal tranduction. 

The Kemp Lab is focused on understanding how metabolism influences the decisions that cells make. Aging, stem cell differentiation, cancer metastasis, and inflammation rely on progressive changes in metabolism resulting in increased levels of reactive oxygen species. Collectively, the accumulation of these molecules is known as cellular oxidation, and pathological levels are referred to as oxidative stress. Our lab develops systems biology tools for investigating how cellular oxidation influences cellular fate and interpretation of cues from the extracellular environment. We are interested in the collective behavior that arises during stem cell differentiation, immune cell responses, or drug treatments from metabolic diversity in individual cells. Because of the numerous biochemical reactions involved, we develop computational models and analytical approaches to understand how complex protein network properties are influenced by redox-sensitive proteins; these proteins typically have reactive thiol groups that are post-translationally regulated in the presence of reactive oxygen species to alter activity and/or function. Experimentally, we develop novel high-throughput single cell techniques for the detection and quantification of intracellular oxidation.

Robert Butera


 

Biography:

Robert Butera is a Professor jointly appointed in the School of Electrical/Computer Engineering at Georgia Tech and the Wallace H. Coulter Dept. of Biomedical Engineering at Georgia Tech and Emory University, both in Atlanta, GA USA.  He is also the one of the founders of the Neural Engineering Center, focused on bringing together clinicians and neuroscientists with engineers to develop novel methods for neuromodulation, where he continues to serve on the executive committee. His lab develops methodologies for selectively stimulating and blocking peripheral nerve activity for sensorimotor and organ modulation applications.  His group also develops open software (http://www.rtxi.org) for enabling real-time closed-loop control of electrophysiology experiments and more recently is developing ultra-low cost open hardware to do the same (http://www.puggleboard.com).  For over 15 years Dr. Butera’s lab has been established in the fields of cellular neurophysiology and computational neuroscience and the development of novel experiments that combine the two through real-time computing. This experience and recent clinical collaborations has motivated his lab to shift research direction over the past few years towards translational neuroscience applications.  Professionally, Dr. Butera serves as the Vice-President for Publications for the IEEE Engineering in Medicine and Biology Society.  Dr. Butera is a Fellow of AIMBE and AAAS and a Distinguished Lecturer of the IEEE Engineering in Medicine and Biology Society.
