Hello, and welcome to my website. I’m an assistant professor in the Psychology department at New Mexico State University.
My research interests fall under the broad heading of visual cognition, including research into visual attention and memory, and computational models of both. My other research interests include (but are not limited to): development of alternative methods for multidimensional scaling, similarity as a psychological construct, working memory, and spoken word perception.
Here’s a short video about what we do in my lab:
And here is a quick “Eye on research” video, produced by NMSU. It gives a brief intro to some of our work, and to eye-tracking technology:
My primary work focuses on memory and attention, with an emphasis on human visual processing. In my research, I employ converging techniques; specifically, I combine standard behavioral measurements (e.g., reaction time, similarity ratings) with more sensitive experimental techniques (e.g., eyetracking, tDCS), physiological indexes (e.g., pupillometry, heart rate), advanced statistical procedures (e.g., multidimensional scaling), and computational modeling.
My immediate goals involve conducting theory-driven experiments that investigate decision-making in visual search, with the long-term aim of establishing computational models of the underlying cognitive processes. This theoretical aim is coupled with more applied goals, in particular learning how to alleviate problems that plague professional visual searchers, such as medical and security screeners.
As a professor, I balance my time between research, teaching, and service. In my labs, we have a state of the art eye-tracker, several banks of testing computers, and the resources to collect data from undergraduates at NMSU and from members of the public. We also employ touch screen monitors, virtual reality headsets, mobile eye-tracking, and transcranial direct current stimuliation. I currently have six graduate students working with me. My research is highly collaborative; I have collaborations within NMSU (both inside and outside of the Psychology department), in institutions around the US (e.g., Harvard Medical School, Arizona State University, Louisiana State University) and several abroad (e.g., the University of Southampton, the University of Sussex). I regularly publish my work in peer-reviewed journals.
My regular teaching load is divided across undergraduate and graduate classes, and includes courses such as quantitative methods in psychology, research methods, memory, cognition, sensation and perception, history and systems, and others. I also mentor several organizations. I am the Associate Director of the College of Art’s and Sciences Discovery Scholars Program. I am faculty mentor to the NMSU chapter of Psi Chi, and the faculty mentor to the Organization for Skepticism and Scientific Literacy.
I also regularly provide service to the scientific community. I am a journal reviewer for nearly a dozen different scientific peer-reviewed outlets and a consulting editor for three journals (the Journal of Experimental Psychology: Human Perception & Performance; Attention, Perception & Psychophysics; and the Journal of General Psychology), I will become an associate editor at AP&P in January, I contribute to popular science magazines (e.g., Scientific American), I was twice a co-organizer for an international psychology conference (the Object Perception, Attention and Memory meeting), and I make a concerted effort to share my work with other researchers. This involves the creation of databases that can be used in experimental psychology, and the sharing of many of my software programs (all of which can be found on this website).
If you are interested in collaborative research, or in becoming a graduate student or research assistant in my lab, please feel free to contact me via email. My contact information is listed below.
