# Meet the Researchers

Mark Bodner is Co-founder and President of Research at the MIND Research Institute. He is an adjunct professor of mathematics at the University of Pittsburgh and visiting professor at the Institute of Cognitive Neuroscience at the East China Normal University. He formerly held faculty appointments at the Johns Hopkins University’s Department of Neurosurgery, and joint faculty appointments at UCLA’s Neuropsychiatric Institute, and UC Irvine’s Department of Physics. His research focus is computational neuroscience and mathematical biology. Recent work has focused on understanding the patterns and mechanisms of activity in networks of neurons, and working memory, and how seizures arise in cortical networks in epilepsy and how they may be terminated through specific brain stimulation. Other work focuses on the application of knot theory and group theory in modeling the structure and function of DNA.

Mark has received several national and international awards including the J.J. Sakuri prize; the Ettore Majorana award at the Majorana School of Subnuclear Physics in Erice, Italy; and the Halliday and Resnick Award in physics for solving the liquid crystal structure of particular cholestoral esters linked to cardiovascular disease. He has been a grant recipient from the National Science Foundation for demonstrating the feasibility of elucidating cognitive function in awake behaving primates using optical and infrared imaging methods. Mark received his Ph.D. and master’s degrees in theoretical high-energy and mathematical physics from UCLA and bachelor’s degree in both physics and chemistry from the University of Pittsburgh. He received a fellowship from the National Institute of Mental Health for postdoctoral work in Neuroscience at UCLA. Mark has over 100 papers and abstracts published in neuroscience, physics and mathematics.

Robert Moody is Emeritus Professor of Mathematics and Statistical Sciences at the University of Alberta and Adjunct Professor of Mathematics at the University of Victoria. Recent research has involved studying the mathematical aspects of quasi-crystals, diffraction, and long-range aperiodic order. His efforts at the MIND Research Institute are particularly directed toward developing a sound mathematical foundation for the theory of pattern, particularly in its dynamical and neurological aspects. Robert received his Ph.D. from the University of Toronto. He was elected to the Royal Society of Canada in 1980 and was awarded the 1994-95 Eugene Wigner Medal for "work on affine Lie algebras that has influenced many areas of theoretical physics." He was twice honored by the Canadian Mathematical Society. His discovery, independently from and simultaneously with V.G. Kac, of an enormous new class of infinite dimensional Lie Algebras, which are now called Kac-Moody algebras, is considered one of the seminal events in the history of mathematics in the last half of the twentieth century.

Jiri Patera is Professor of Mathematics at the University of Montreal’s Department of Mathematics and Statistics, and a former visiting faculty member in the Department of Physics at the California Institute of Technology. Jiri’s recent work focuses on lattice-based special functions in multi-dimensional cases and their exploitation in Fourier analysis of digital data. He also focuses on application of Lie group and symmetry towards the modeling of biological and physical phenomena. Jiri received his Ph.D. in theoretical physics at the Czech Technical University in Prague, and performed postdoctoral work at Imperial College in London. He has been the recipient of the CRM-CAP Prize in Theoretical and Mathematical Physics for his outstanding contributions to Lie group and Lie algebra theory, with applications to elementary particle and nuclear physics and to quantum chemistry, and more recently for his significant contributions to the mathematical theory of quasicrystals, with applications to condensed matter physics and cryptography. Jiri’s work has had an impact on nuclear and elementary particle physics, quantum chemistry and solid state physics. His research on quasi-crystals even had implications in cryptography.

Yongdi Zhou is the Zijang Professor at the Institute of Cognitive Neuroscience at East China Normal University, and Adjunct Professor in the Department of Neurosurgery at Johns Hopkins University. Yongdi’s research focuses on determining the neuromechanisms of perception and working memory. Current work focuses on the neurophysiology of somatosensory cortex (primary somatosensory cortex, SI; secondary somatosensory cortex, SII) in tactile working memory and cross-modal stimulus-stimulus associations. An understanding of the neuromechanism of tactile memory and the neurophysiology of tactile cross-modal association may clarify the role of parietal cortex both in sensorimotor learning and deficits following parietal lesions. Yongdi received his Ph.D. in neuroscience from the UCLA.
