Albert I. Chen, PhD
Albert Chen is an Associate Professor at Scintillon Institute. Before joining Scintillon, he was an Assistant Professor at Nanyang Technological University in Singapore. Albert received his undergraduate degree at the University of Illinois and Ph.D. from Columbia University where he examined the specification of neuronal subtype identity and axonal targeting in the spinal cord. As a postdoctoral fellow at the University of California, San Francisco, he transitioned to studying supraspinal motor structures, exploring the mechanisms underlying the assembly and maintenance of neural circuits in the cerebellum, a brain region critical for sensorimotor integration and voluntary motor control.
Research in the Chen Lab employs a multidisciplinary approach to pursue two major aims: 1) to define the molecular, anatomical, and functional distinctions of neuronal subpopulations in the nervous system that control specific behaviors; and 2) to identify and characterize genes that direct the assembly and maintenance of neural circuits. These general issues are examined through the analysis of local and long-range circuits in subcortical brain centers important for coordination and refinement of movement, motor learning, and cognitive behaviors using genetic and viral circuit tracing, neural manipulations, and behavioral approaches in mice.

Dorit Hanein, PhD
Hanein’s research is at the interfaces between structural biology, cell biology, systems biology, and engineering science. Hanein is leading efforts in combining light microscopy with cellular tomography to permit the placement of dynamics multimolecular protein complexes into their functional context in whole mammalian cells. Through these efforts, she made seminal contributions to our knowledge of the structure, assembly and regulation of actin cytoskeleton and its associated macromolecular assemblies, to the development of techniques and protocols for correlative light and in-situ cellular tomography of protein structures in intact hydrated mammalian cells at cryogenic temperatures, and to the evolution of quantitative cryogenic electron microscopy. This workflow is tied to high-resolution, live-cell fluorescence imaging that are used to pinpoint the location of single proteins. With the advent of the new generation of cryo-electron microscopy equipment, including direct detection technology, phase plate devices, and automation capabilities, these efforts place Dr. Hanein research at the forefront of exciting new developments at the interface between cryo-EM, cell biology, and systems biology. The resulting quantitative integration of scales between macroscopic cellular behavior and high-resolution structural changes carries high impact in both medicine and basic biological research.

Stuart Lipton, MD, PhD
Neurologist and neuroscientist Stuart Lipton, MD PhD, is a renowned expert in dementia, running a large basic-science laboratory, and an active clinical neurology practice at the University of California, San Diego. He is best known for discovering the mechanism of action and contributing to the clinical development of the latest FDA-approved treatment for Alzheimer’s disease (memantine/Namenda®, an uncompetitive antagonist at the NMDA receptor). Lipton and collaborator Jonathan Stamler discovered the chemical reaction termed S-nitrosylation as a ubiquitous redox-regulator of protein function and have recently combined memantine with S-nitrosylation technology to produce a new drug, NitroMemantine, that displays disease-modifying activity in animal models of Alzheimer’s disease. Lipton’s group also discovered the GluN3 family of modulatory NMDA receptor subunits, characterized the molecular pathways for protecting neurons with erythropoietin, and discovered the transcription factor MEF2C. Recently, his group showed MEF2C serves as a master switch for neurogenesis from human neural stem cells and is regulated by S-nitrosylation. They found that dysregulated MEF2C is involved in the pathogenesis of autism spectrum disorders, vascular dementia, Parkinson’s disease, and Alzheimer’s disease. Lipton is a recipient of the Ernst Jung Prize in Medicine, is an elected a fellow of the AAAS Neuroscience section, and a recent awardee of the Alzheimer’s Disease Association.
Educated at three Ivy League universities (Cornell, University of Pennsylvania, Harvard), Dr. Lipton completed scientific training as a postdoctoral fellow with Torsten Wiesel when Wiesel won the Nobel Prize.
