As the director of the Penn Neurology VR Laboratory, I currently work as a collaborator and software developer with the goal of bringing virtual and augmented reality approaches and experimental methods to neuroscience, psychology, anthropology, and medical researchers. To explore this, my research utilizes virtual reality and augmented reality tools to explore the complexities of human perception at ancient Maya sites in the Yucatan and Belize. He currently serves on the Boards of The College of Physicians of Philadelphia and has served on the boards of Haverford College, the Norris Square Neighborhood Project and the Associated Services for the Blind and Visually Impaired.ĬV for Anjan am interested in human perception of landscapes and architectural spaces and how they shape both cognitive and cultural processes in contemporary and archaeological contexts. He is a founding member of the Board of Governors of the Neuroethics Society, the past President of the International Association of Empirical Aesthetics, and the past President of the Behavioral and Cognitive Neurology Society.

He has received the Norman Geschwind Prize in Behavioral and Cognitive Neurology and the Rudolph Arnheim Prize for contribution to Psychology and the Arts.

He wrote The Aesthetic Brain: How We Evolved to Desire Beauty and Enjoy Art and co-edited Neuroethics in Practice: Mind, Medicine, and Society and The Roots of Cognitive Neuroscience: Behavioral Neurology and Neuropsychology. Because topographically complex substrates are easily fabricated and LC defects are readily reconfigured, this work lays the foundation for a versatile, robust mechanism to direct assembly dynamically over large areas by controlling surface anchoring and associated bulk defect structure.Professor of Neurology, Psychology, and Chatterjee is a Professor of Neurology, Psychology, and Architecture and the founding Director of the Penn Center for Neuroaesthetics. When the surface density of the colloids is high, they form a ring near the defect and a hexagonal lattice far from it. These defects source elastic deformations that direct the assembly of the interfacially trapped colloids into ring-like assemblies, which recapitulate the defect geometry even when the microposts are completely immersed in the nematic. Specifically, by confining the nematic LC in an array of microposts with homeotropic anchoring conditions, we cause defect rings to form at well-defined locations in the bulk of the sample. Here, we report on complex open structures organized via interactions with defects in the bulk.

Spherical colloids with homeotropic anchoring trapped at the interface between air and the nematic LC 4-cyano-4′-pentylbiphenyl create quadrupolar distortions in the director field causing particles to repel and consequently form close-packed assemblies with a triangular habit. We exploit the long-ranged elastic fields inherent to confined nematic liquid crystals (LCs) to assemble colloidal particles trapped at the LC interface into reconfigurable structures with complex symmetries and packings.
