Biochemical basis of learning and memory
When we learn something, connections between neurons in our brain grow stronger. This is mediated by a complex machinery of molecules inside the neuron that can receive and transmit signals and set in motion a series of functional and structural changes. We work on understanding how those molecules work together and regulate each other. In order to do this, we build computer models of neuronal compartments and of the molecules in them and run computer simulations of how they react to specific events, such as the activation of a neuronal connection. These simulations help us understand how these systems work, how they are affected by neurological disorders, and what effect specific drugs are likely to have. We are part of the Patrick Wild Centre for Research into Autism, Fragile X Syndrome and Intellectual Disabilities.
We are also interested in developing both the conceptual frameworks and the computational tools necessary for understanding and computationally representing living biochemical systems such as those underlying learning and memory.
Using online data to understand student learning
Another part of our research looks at questions around learning and memory at the level of individual learners. Topics of interest include the use of online learning tools, and the learning of computational and quantitative concepts.
