Meet Our Team


Principal Investigator


FARB David H. Farb, Ph.D., Professor and Chairman of Pharmacology

As Director of the Laboratory of Molecular Neurobiology, Dr. Farb focuses on the identification of pharmacological treatments for mental disorders of learning and memory. His research integrates existing electrophysiological, behavioral, pharmacological, and molecular genetic technologies in a novel systems-level platform for assessing the impact of cognitive enhancers such as neuroactive steroids upon fundamental hippocampal systems for pattern separation (encoding), and pattern completion (retrieval) that are believed to be essential for cognition in all mammals, including man.

    Senior Researchers

    Marcia Ratner, Ph.D., D.A.B.T., Project Manager

    Dr. Ratner is a Board Certified Toxicologist and Behavioral Neuroscientist. She is the senior member of the in vivo electrophysiology team which is actively investigating how chemicals alter learning and memory function and disease progression in freely behaving rodent models of age-related neurodegenerative disease. The major advantage of in vivo electrophysiology over other functional measures of neural network activity such as regional cerebral blood flow is in the ability of this technology to effectively differentiate the activity of inhibitory interneurons from that of excitatory pyramidal cells both across brain regions and within subregions. This highly translational objective approach to drug discovery is well-suited for target-based as well as repurposing studies of drug-induced changes in both single unit activity and local field potentials implicated in various aspects of cognition.

    10-3009-PHARMAHEAD_Kumaresan-015-150x150 Vidhya Kumaresan, Ph.D., Research Assistant Professor

    Dr. Kumaresan’s overall research objective is to study neuronal activity-dependent plasticity and its relevance for learning, memory and pathological plasticity under pinning brain disorders.  She collaborates with Dr. Farb in elucidating neuronal plasticity elicited by neurosteroids. The major focus of Dr. Kumaresan’s research is to understand the neurobiological bases of addiction to psychostimulants. Dr. Kumaresan employs a novel approach of using cell-permeable peptides that disrupt protein-protein interactions in vivo in order to study ongoing behavior. Knowledge gained from these studies will also be applicable to the treatment of other brain dysfunctions involving persistent memories such as PTSD.


    Scott Downing, Ph.D.Bioinformatics Research Scientist

    Dr. Downing earned his doctoral degree from the Department of Pharmacology here at the BUSM. He is an electrical engineer with extensive experience in computer programming. He works closely with Drs. Farb and Ratner to develop the specialized computer codes necessary for analysis of the large amounts of data acquired in our in-vivo electrophysiological studies. Dr. Downing also oversees implementation of the parallel computer processing and unsupervised machine learning techniques necessary to efficiently and reliably sort the waveforms of action potentials from individual neurons into “clusters” for subsequent analysis.
