New Efforts in Data Science

Posted on Feb 28, 2020

Palmeri has been named Director of Undergraduate Research at the Vanderbilt Data Science Institute, is currently leading an effort to create an undergraduate minor in data science, and is part of a new Data Science: Next Generation Committee appointed by the Provost “to evaluate current computing expertise and resources at Vanderbilt” and “will focus on enhancing the strengths of synergistic disciplines while connecting related research centers and efforts under a common umbrella. It also will seek to expand the data science master’s program and launch a data science minor and other interdisciplinary computing minors to better serve undergraduate students.”

National Endowment for the Arts Grant funded

Posted on May 19, 2019

Palmeri and Gauthier are collaborating with the Albright-Knox Art Gallery in Buffalo, New York, on a two-year project that recently earned a National Endowment for the Arts (NEA) Research: Art Works program award. The project is a scientific study testing whether visual art training can enhance visual perception and visual cognition skills. The Albright-Knox’s Innovation Lab has played a key role in bringing together leading experts in visual arts education, visual perception and visual cognition, and vision, and other collaborators include the Ontario College of Art and Design University and the State University of New York at Buffalo. The team of interdisciplinary partners seeks to combine an art-historical approach to understanding images with a scientific understanding of high-level vision. An arts training program, developed in consultation with OCAD U, will draw from existing museum programs and workshops, as well as basic principles taught in introductory visual studies and visual arts courses, in a series of lessons featuring artworks from the collection of the Albright-Knox. In collaboration with the museum, Vanderbilt will test the impact of the training program on visual perception and visual cognition. The team hopes to use the results of these tests to help shape a curriculum for enhancing high-level visual skills for people from all walks of life, establishing an even more vital role for the visual arts and arts organizations.

Welcome New Members to the CatLab

Posted on Jun 24, 2018

We welcome three new members to the CatLab this summer:

Greg Cox received his PhD from Indiana University in Psychological and Brain Sciences and Cognitive Science, where he worked with Rich Shiffrin. Greg completed a postdoctoral fellowship at Syracuse University and will be joining our lab as a postdoctoral fellow in July. He will be working with Palmeri, Logan, and Schall on model-based cognitive neuroscience. Greg is interested in the development of experimental techniques and mathematical/computational models that help us understand how neural and cognitive processes jointly unfold across time.

Craig Sanders is receiving his PhD from Indiana University in Psychological and Brain Sciences this summer, where he has been working with Rob Nosofsky. Craig will be joining our lab as a postdoctoral fellow next month. He will be working with Palmeri and Gauthier on project using cognitive and deep learning models to understand individual differences in visual cognition. Craig is broadly interested in combining machine learning (especially deep learning) with classic cognitive models to understand how people perceive, categorize, and mentally represent objects.

Jason Chow completed his undergraduate degree in May 2018 at the University of Toronto, he worked with CatLab alumnus, and now University of Toronto faculty member, Michael Mack on the development and validation of a printable 3D stimulus set for categorization experiments in visual and tactile modalities. As a PhD student at Vanderbilt, Jason will be working with Palmeri and Gauthier on combining computational modeling and neuroimaging to gain insights on perceptual expertise.

Mathieu Servant wins Bob Fox Award of Excellence in Postdoctoral Research

Posted on May 15, 2018

Congratulations to Mathieu for being the 2018 winner of the Bob Fox Award of Excellence in Postdoctoral Research.

This award is granted to a postdoctoral fellow in the Department of Psychology at Vanderbilt who has demonstrated outstanding achievement in research. It is named in honor of Robert “Bob” Fox for his essential role in guiding the evolution of of the department over a five-decade period starting in the mid-60’s. Bob enjoyed a highly productive research career, with publications in major journals and continuous grant funding for decades, and he trained a number of students and postdocs who went on to successful careers themselves. Bob has served as an inspiration to generations of subsequent faculty members. This award not only serves as a humble note of appreciation for Bob’s numerous accomplishments, it also acknowledges the critical role that postdoctoral fellows play in the scientific vibrancy of our department. Postdocs are not only highly skilled, accomplished and dedicated young scientists, they also are reference models for our graduate students and are the first to represent Vanderbilt at the next academic level.
