David Barack, PhD
2019 K99/R00 Awardee
Columbia University | Postdoctoral Research Scientist
University of Pennsylvania | Visiting Scholar
David Barack is a neuroscientist and philosopher. His neuroscientific investigations target the neural circuits of foraging decisions in humans and non-human primates. He is particularly interested in how primates search for information, how information is encoded in the brain independently of reward, and how information guides inferences to learn about states of the world. David’s philosophical work explores the conceptual foundations of cognitive neuroscience, especially the underlying dynamical basis for cognition, and the foraging foundations of reasoning. David received his PhD in philosophy from Duke University, worked as a postdoc at the University of Pennsylvania, and matriculated to Columbia as a Presidential Scholar in Society and Neuroscience. David is now a postdoc in neuroscience working under the tutelage of Dr. Daniel Salzman as well as a visiting scholar in philosophy at Penn.
Anna Blazejewska, PhD
2019 K99/R00 Awardee
Massachusetts General Hospital | Post-Doctoral Fellow
Website
Anna Blazejewska holds two master’s degrees, in philosophy (cognitive science) and in computer science. Her PhD work at Sir Peter Mansfield Imaging Center in Nottingham focused on investigating brain tissue properties with high resolution 7T MRI including quantitative analysis of iron- and myelin-related MR contrasts as well as correlations of the ex vivo MRI data with histology. During the first two years of her postdoctoral training she was studying the changes of T2* relaxation times due to tissue maturation in healthy developing fetal brain and their impact on protocol optimization for fetal fMRI. In late 2015 Anna joined A. A. Martinos Center for Biomedical Imaging at MGH as a post-doctoral fellow where she has been working on improving the performance of parallel imaging techniques for functional MRI at ultra-high field strengths, developing anatomically informed intracortical smoothing methods for high spatial resolution fMRI and investigating spatial specificity of the early positive BOLD fMRI response across cortical depths. The goal of Anna’s K99/R00 project is to develop a model of microanatomical and microvascular features of cortical brain tissue using ex vivo and in vivo MRI and histology stains to help remove confounding factors and make fMRI measurements more specific to neuronal activity.
Aparna Bhaduri, PhD

Anna Jafarpour, PhD
2019 K99/R00 Awardee
University of Washington | Senior Fellow
Website
Anna Jafarpour is a post-doctoral cognitive neuroscientist working with Dr. Elizabeth Buffalo at the University of Washington and Dr. Robert Knight at the University of California, Berkeley. Previously in her Ph.D. at the University College London, she used machine learning to decode the content of memory and determined the neural dynamics of retrieving visual memories and retaining a sequence of visual items for a short time. In her research, Dr. Jafarpour found that temporal and spatial memories of naturalistic sequences, that are encountered in daily transportation, are distorted with familiarity. Being extremely interested in the impact of everyday life on memory, in her postdoctoral research, she investigated neural responses to contextual expectations in naturalistic stimuli such as speech and movies. Dr. Jafarpour used intracranial EEG from the hippocampus and the prefrontal cortices of epileptic patients to reveal that expectation built from prior knowledge plays a key role in regional neural responses. Most recently, she observed that individual differences in perception and memory of a sequence of events related to the retention capacity of short-term memory. Her current research focuses on the neural circuits for perception and memory of lifelike sequences of events using intracranial EEG and computational techniques.
Lucas Pinto, MD, PhD
2019 K99/R00 Awardee
Princeton Neuroscience Institute | Postdoctoral Research Fellow
Website
Dr. Pinto obtained his medical degree from the Federal University of Minas Gerais, Brazil, in 2006. He then did a Master's degree in physiology at the same university, where he studied visual processing in owls with Jerome Baron. Dr. Pinto got his Ph.D. in neuroscience from the University of California, Berkeley in 2014, working in in Yang Dan's laboratory. He investigated how circuits downstream of the sensory cortex participate in perceptual decision-making. He moved to the Princeton Neuroscience Institute in 2015 for his post-doctoral research in the laboratories of Dr. David Tank and Dr. Carlos Brody. Dr. Pinto is broadly interested in neural mechanisms underlying cognition, both at the local circuit level and in terms of large-scale interactions between different brain areas. He uses a combination of recording, perturbation and computational techniques to study decision-making behavior. More specifically, his current work investigates how cortical areas interact at large scales to support decision-making relying on the gradual accumulation of sensory evidence, and how the cognitive demands of different tasks modulate cortical dynamics.
