FRAXA is indebted to these prominent investigators who volunteer their time to help us devise strategies for advancing research and provide expert opinion on research proposals.
Many of our advisers also run active academic research laboratories, where they are conducting work on Fragile X. Others are involved in Fragile X and autism programs at pharmaceutical companies.
Three of FRAXA’s Scientific Advisors are winners of the Nobel Prize in Medicine: James Watson, PhD, Eric Kandel, MD, and Susumu Tonegawa, PhD.
Mark Bear, PhD
Our overarching interest is in the question of how experience and deprivation modify synaptic connections in the brain. Experience-dependent synaptic plasticity is the physical substrate of memory, sculpts connections during postnatal development to determine the capabilities and limitations of brain functions, is responsible for the reorganization of the brain after damage, and is vulnerable in numerous psychiatric and neurological diseases and contributes to their symptoms.
Elizabeth Berry-Kravis, MD, PhD
Outcome measures for clinical trials are essential for investigation of new treatments, and this is an area of great need in fragile X research. Dr. Berry-Kravis has made invaluable contributions to our understanding of how best to conduct clinical trials in fragile X. Her first clinical trial in Fragile X funded by FRAXA was of AMPAkines, in the mid 2000s, and since then she has been funded by FRAXA to run a trial of Lithium in 15 individuals with fragile X and to validate a new automated video tracking system for quantifying physical activity as an outcome measure for fragile X clinical trials. She has also conducted large scale Phase III trials of mGluR5 antagonists.
Graeme Bilbe, PhD
Prior to joining DNDi in June 2012, Dr. Bilbe was Global Head of Neuroscience Discovery at Novartis tasked with discovery and early development of novel treatments for brain diseases. He served in several management positions at Novartis including the Novartis Institutes for Biomedical Research Leadership Team, Head of Research for the Neuroscience Franchise, which brought two innovative drugs, Exelon patch for Alzheimer’s disease and Gilenya for multiple sclerosis, to the fruition.
Dr. Bilbe led the scientists who discovered and developed AFQ056, a metabotropic glutamate receptor 5 antagonist, which demonstrated early clinical efficacy in L-DOPA-induced dyskinesias in Parkinson’s disease and also improved symptoms in fragile X syndrome patients.
Dr Bilbe has the overall responsibility of building DNDi’s project portfolio and advancing the discovery and development of new treatments for neglected diseases.

Oswald Steward, PhD
Dr. Steward’s research program explores how neurons establish, maintain, and modify their synaptic connections. Information storage in the nervous system is thought to be mediated by changes in the strength of individual synapses. These changes in turn are determined by adjusting the structure and/or molecular composition of the synapse through a process that requires the expression of particular gene products. But how gene products are targeted to individual synapses remains a mystery.
Almost 25 years ago, Dr. Steward discovered that polyribosomes were selectively localized beneath postsynaptic membrane specializations on the dendrites of CNS neurons. Polyribosomes are the basic machinery of protein synthesis. Their localization at synapses immediately suggested how neurons might manage the task of synthesizing gene products for the thousands of individual synaptic sites that are present on a typical CNS neuron. Specifically, the localization of polyribosomes at synapses implied that certain key proteins that were important for the function of that individual synapse might be synthesized on site, and that this local synthesis might be controlled by signaling events at the individual synapse. More recent work has revealed that FMRP, the protein missing in fragile X, is a key regulator of this activity-dependent protein synthesis in dendrites.
Susumu Tonegawa, PhD
The main interest of Professor Susumu Tonegawa’s lab is to understand the molecular, cellular, neuronal circuitry, and neural systems mechanisms underlying learning and memory and associated cognitive functions. They have thus far focused on hippocampus-dependent memory, i.e., memory of events, facts, space, etc. The hippocampus consists of multiple interconnected areas such as area CA1, CA3 and the dentate gyrus (DG), each of which contains a unique set of neurons composing a distinct cellular network. They aim to identify the roles of specific proteins (e.g., NMDA receptors), synaptic plasticity and neural circuitries in each of these areas in different stages of the mnemonic process such as memory acquisition, consolidation and recall.
Another important development in the lab was the identification of genes (calcinearine and PAK kinase) whose reduced activities increased susceptibility to schizophrenia and fragile X mental retardation, respectively. These discoveries were made by combining the behavioral analysis of genetically engineered mice and/or genetic analysis of DNA from human patients.
Stephen Warren, PhD
Investigator, Howard Hughes Medical Institute
The Warren Laboratory has had a long-standing interest in fragile X syndrome, the most common inherited cause of intellectual disability. From the original gene identification to biochemistry to cell biology to neurobiology, the lab has contributed to an ever increasing understanding of the pathophysiology of fragile X that has led to drug screens and current clinical trials. In addition, the laboratory more recently has turned its attention also to the genetic and epigenetic influences on autism, schizophrenia, and bipolar disorder.
James D. Watson, PhD
Dr. James D. Watson, together with Francis Crick and Maurice Wilkins, was awarded the Nobel Prize for Physiology or Medicine in 1962 for their discoveries concerning the molecular structure of DNA and its significance for information transfer in living material. He is Chancellor Emeritus of the Watson School of Biological Sciences at Cold Spring Harbor Laboratory.
Robert Wong, PhD
Dr. Wong is Distinguished Professor and Chairman, Department of Physiology and Pharmacology, and Professor, Department of Neurology, at SUNY Downstate. He and his team design studies to examine the functional organization of the hippocampus. The properties of synaptic interactions mediated by the neurotransmitters GABA and glutamate are studied in some detail in order to understand how these interactions affect the overall network output.
Jerry Yin, PhD
Dr Yin’s overall goal is to understand nervous system function — especially memory — during complex behavior at the molecular level. His team’s basic approach involves transgenic manipulation of genes followed by behavioral, cellular and molecular analyses.
In all animals, long-term memory, requires acute gene expression around the time of training. A number of very interesting questions arise:
How does a neuron only strengthen the recently active synapse, and not other surrounding synapses? How can memories persist for so much longer than the half-lives of most proteins and protein structures? If “use it or lose it” applies memories, as it seemingly does to synaptic plasticity, how and when do neurons “replay” experiences?
