About me
What I currently do and where I've been:
I am currently the Operating Director and Senior Research Scientist of the Human Neuroscience Laboratory in the Department of Psychology and Neuroscience at Boston College. Previously, I was a postdoctoral fellow in the Department of Psychology at Harvard University, working with Dr. Daniel Schacter. I completed my PhD in psychology and neuroscience at Boston College, supervised by Dr. Scott Slotnick, followed by a postdoctoral fellowship at the University of Texas at Dallas, working with Dr. Michael Rugg.

My research:
Episodic memory refers to memory for unique events that happened in a specific time and place. Scientists think of episodic memory not as a video camera that allows us to play a literal recording of a past experience, but instead as a constructive process: we remember bits and pieces of an event and link them together reconstructing the original episode. One of the most important questions faced by memory researchers is why episodic memory is supported by such constructive processes that are inherently prone to error and failure?
Recent work has shown that the same constructive processes that support episodic memory are adaptive in that they help to support other human abilities. For example, an important function of episodic memory is to support the episodic simulation of future events (i.e., the ability to draw on elements of past experiences in order to construct episodes and mentally “try out” versions of what might happen in the future).
The focus of my research program is twofold: the primary focus is to understand the neural mechanisms supporting episodic memory, and the secondary is to examine the cognitive and neural underpinnings associated with episodic simulation, and other adaptive functions that draw on episodic processing, like divergent creative thinking and means-end problem solving. For example, we have shown that the same constructive memory processes that support episodic memory have an adaptive benefit in supporting divergent creative thinking and open-ended problem-solving, but also have negative consequences in the form of greater false memories (Thakral et al., 2023, Memory & Cognition; Thakral et al., 2021, Cognition).
I utilize a variety of cognitive neurosciences techniques in my research program:
fMRI (functional magnetic resonance imaging) provides excellent spatial resolution which can be used to assess which neural regions are associated with a given process
TMS (transcranial magnetic stimulation) provides the opportunity to assess the necessity of a given neural region for a given cognitive process
ERPs (event-related potentials) provide excellent temporal resolution which can be used to assess when different processes are engaged
Some examples:
Using TMS, we examined the necessary role of neural regions in episodic memory and episodic simulation
(e.g., Thakral, Madore Kalinowski, & Schacter, 2020; Thakral, Madore, & Schacter, 2017; Thakral & Slotnick, 2011)
Using fMRI, we tested whether sensory and non-sensory neural processing contributes to the subjective experience of episodic memory
(e.g., Thakral, Madore & Schacter, 2020; Thakral, Wang, & Rugg, 2015)
Using ERPs, we identified when sensory processing occurs during episodic memory
(e.g., Thakral & Slotnick 2015)
