I am currently a postdoc in the Functional Modeling Systems group, directed by Christian Lebiere. I earned my PhD in Cognitive Science from Mississippi State University. My research interests broadly include comprehension, prediction/anticipation, problem-solving, learning, and decision making. The focus of my current research is in modeling human decision making of adversaries in a cyber-security domain, understanding how humans respond to deception, and modeling end-user response to phishing attacks. In other research, I am interested in how experts generate and select appropriate courses of action in dynamic and time-pressured situations.

I am interested in how speech, language, and communication skills are affected by neurological impairments such as stroke and dementia. Working with Brian MacWhinney, I am involved in creating shared databases for research in these and other related areas. Using and improving computer-based tools for language transcription and analysis is also a big focus of my work.

Timothy Keller

Timothy Keller

Senior Research Psychologist

Address
5000 Forbes Avenue
Pittsburgh, PA 15213

Senior Research Associate with expertise in fMRI. He is working on all of the fMRI projects. He has just the right computational skills to deal with the intensive data processing associated with fMRI data, as well as neuroanatomical knowledge for data interpretation. His substantive interests are in working memory, language, and spatial thinking. His Ph.D. is from the University of Missouri. He was previously an NIMH Post-Doctoral Fellow for two years.

Postdoctoral Fellow

Sahil is a postdoctoral researcher in the Holt Lab. He received his PhD in Psychological Sciences from the University of Connecticut in 2021. Sahil’s research focuses on the cognitive and neural mechanisms that support speech perception, and he is specifically interested in how listeners leverage different sources of information (their knowledge of who is talking, their knowledge of what someone is likely to say in some given context, etc.) to guide their interpretation of the acoustic signal. Outside of the lab, Sahil enjoys books, baking and boxing, as well as things that don’t start with the letter B.

My current research explores the cognitive and neural mechanisms through which scientific concepts are learned. I also developed a multiple cortical network theory of discourse processing with colleagues at the Center for Cognitive Brain Imaging (CCBI). My broader research program focuses on the interaction of learning, language and the brain during the instructional process. I use functional Magnetic Resonance Imaging (fMRI) and repetitive Transcranial Magnetic Stimulation (rTMS) to study cortical networks that subserve reading and learning. I have studied these networks in English speakers, bilinguals and individuals with autism. My Ph.D. is from the University of Massachusetts at Amherst and I previously worked at the Learning Research & Development Center at the University of Pittsburgh.

My current research examines how people think about, discuss, and engage with their social world across behavioral, ecological, and neural levels. Moreover, I am interested in how these thoughts of the social world provide an ecologically valid foundation for understanding the cognitive mechanisms underlying conceptual association at the individual and group level.

Specifically, I am interested in how peoples' thoughts and feelings (i.e., conceptual associations) involving their societal environment (e.g., healthcare, voting) and social groups within that environment (e.g., race, gender, social economic status) influence their decision to engage with services their society provides and their treatment of people of differing social identities.

The fundamental goal of this body of research aims to identify data-driven patterns of thinking and behavior to illuminate societally systemic and neural mechanisms that contribute to social thought, conceptual associations, and decision making.

I am currently a Presidential Postdoctoral Fellow (2022-2023 cohort) working with both the Cognitive Axon Lab (CoAx) and the Data Driven Diversity Lab (D3) and have served on the Psychology departmental Diversity & Inclusion board as well as co-founded the Diverse Recruitment committee to spearhead college-wide graduate recruitment efforts from underrepresented groups.
