The Contractor Lab

About Us

Principal Investigator

Anis Contractor, PhD

E-mail   |   PubMed 

Anis Contractor received his Ph.D. in neuropharmacology from University College London in the laboratory of Professor Alasdair Gibb, where he studied the functional properties of NMDA receptors. He performed postdoctoral studies at the Salk Institute for Biological Studies with Professor Stephen Heinemann, where he studied the role of glutamate receptors in synaptic plasticity and development. He joined the faculty at Northwestern University Feinberg School of Medicine in 2004, where his laboratory focuses on studies of synaptic and circuit mechanisms underlying neurodevelopmental and neuropsychiatric disorders in mouse models. Contractor is currently the Wendell Krieg Professor of Neuroscience in the Department of Neuroscience with a secondary appointment in the Department of Neurobiology.

My research focuses on using mouse genetic models to study functions of glutamate receptors in brain.  In my spare time, I enjoy hanging out with my family and watching TV!

John Marshall


I am interested in the mechanisms of synaptic plasticity that occur in basal ganglia circuits during procedural learning. I primarily use in vivo imaging, brain slice electrophysiology and analysis of mouse behavior in my projects.  I also enjoy reading, outdoor activities and exploring various ways of preparing food.

BA – Biochemistry & Philosophy – Columbia University

Toshihiro Nomura


I am interested in understanding the synapse pathophysiology of neuronal and neuropsychiatric disorders.  I also enjoy looking for delicious foods and drinks!

Shintaro Otsuka


I’m interested in how neural activity is altered in patients with neurodevelopmental disorders and how it affects their behavior. To resolve this question, I’m utilizing a head-mounted microscope and an operant task to see where and how the neural activity pattern of autistic model mice is altered during perseverative behavior, which is one of the principle symptoms in the autistic patients.

PhD – Keio University

Yiwen Zhu


I am currently investigating the role of GluK2 kainate receptors in the process of adult hippocampal neurogenesis. My interest is to better understand mechanisms that regulate the maturation of adult-born dentate granule neurons and how adult-neurogenesis dependent behaviors can be ultimately impacted.  I also enjoy running, shopping, and trying out new restaurants.
BA – Case Western Reserve University

Nai-Hsing Yeh


My research focuses on the role of striatal pathways in the motor learning process. I study the questions by using brain slice electrophysiology and animal behavioral paradigms. Outside of the lab, I enjoy jogging, handcrafting and trying different foods. 
MS – Life Science – National Taiwan University
BA – Life Science – National Taiwan University

Morgane Chiesa


My research currently focuses on understanding the mechanisms of mossy fiber synaptic function. Out of the lab, I enjoy biking, hiking and hanging out with friends.
PhD – Neuroscience – Aix-Marseille University
MS – Neuroscience & Neuropsychopharmacology – Bordeaux Segalen University 
BA – Health Engineering – Henri Poincaré University,

Diana I-Ribera


My research interests are understanding the mechanisms of synaptic disruption underlying neuropsychiatric disorders.
PhD CINVESTAV – Centro de Investigación y de Estudios Avanzados del Instituto Politécnico Nacional – Mexico City

Matt Barraza


I am interested in neurodevelopmental disorders such as autism and epilepsy. For my project, I utilize transgenic mouse models to study synaptic plasticity in the hippocampus. While not in lab, I enjoy watching movies and swimming.
BA – Molecular and Cell Biology – University of California, Berkeley
