John Serences

    John is a UCSD alum and worked with Prof. Hal Pashler as an undergraduate. He moved to Johns Hopkins for grad school and worked with Prof. Steve Yantis, and then moved to the Salk Institute to do a postdoc with Dr. Geoff Boynton. Here is his CV. Request a letter of recommendation.

    Post-doctoral Fellows


    Edward Ester

    Eddie is a postdoc in the Perception and Cognition lab. He earned his B.A. in Psychology from Nazareth College in upstate New York. He then spent two years working in Dr. Charles Folk’s lab at Villanova University, where he earned in M.S. After graduating, he made his way out to the west coast and received a Ph.D. from the University of Oregon, where he worked with Dr. Ed Awh and Dr. Ed Vogel. For his dissertation, he used fMRI to characterize the neural mechanisms that allow individuals to store detailed representations in visual working memory. More recently, Eddie has begun to examine how task demands influence perceptual and mnemonic representations in visual cortex using a variety of techniques, including psychophysics, computational modeling, and fMRI. In his spare time, Eddie is a sports junkie (Go Ducks!) and an avid homebrewer. Here is Eddie's CV.


    Rosanne Rademaker

    Rosanne is a postdoc in the lab. She completed a BSc in Psychology at the University of Groningen and an MSc in Neuropsychology at Maastricht University (both in the Netherlands). During and after her Masters she spent almost 2 years working in the lab of Dr. Frank Tong at Vanderbilt University. She completed her PhD at Maastricht University with Dr. Alexander Sack, exploring the mechanisms of visual short-term memory and how robust such memories are against decay and interference (using psychophysics and TMS). During these years she also collaborated closely with Dr. Janneke Jehee (Donders Institute) and Dr. Sam Ling (Boston University), using fMRI, noise masking, contrast response, and the occasional bucket of ice (!) to look at brain and behavioral changes induced by attention. Here is Rosanne's CV.

    Mary Smith *

    Mary is a sixth year Ph.D. student in the Psychology department. She earned her B.A. from Carnegie Mellon in 2008 concentrating in Music Technology and Psychology. There, she worked in the Cognitive Neuroscience Lab with Dr. Marlene Behrmann studying prosopagnosia. She then moved to The Epstein Lab for two years as an RA, working with Dr. Russell Epstein at the University of Pennsylvania, researching higher-level visual perception via fMRI. The year before grad school, Mary worked as an RA at Stanford Memory Laboratory with Dr. Anthony Wagner. Outside of school, Mary loves extensive traveling, acroyoga, handstands, and crafting.


    Sirawaj (Sean) Itthipuripat **

    Sirawaj is a sixth year Ph.D. student in Neurosciences graduate program at UCSD. He is originally from Thailand. He earned his B.S. in Neuroscience and Psychology at Duke University, where he worked with Dr. Marty Woldorff, a former UCSD neuro grad (very first generation). At Duke, he conducted various EEG studies on multi-sensory information integration, attention, and language. Sirawaj is currently interested in combining EEG/SSVEP with computational modeling and other neuroimaging techniques (e.g. fMRI) to study the temporal dynamics of spatial and feature-selective attention. Sirawaj decided to join the PC lab after John saved his life from trying to surf. This summer he is taking a surfing class to ensure that he will survive graduate school. Here is Sirawaj's CV. Personal Page.


    Stephanie Nelli #

    Stephanie is a fourth year Ph.D. student in the Neurosciences graduate program. She earned her B.A. in Mathematics in 2013 from UNC-Chapel Hill, where she worked in Dr. Leslie Morrow's preclinical neuropharmacology lab. She is interested in the role of neural oscillations in both stimulus-evoked and internally generated perceptions. Stephanie is currently using frequency tagged stimuli and EEG to explore feature-selective information processing through reconstruction models.


    Vy Vo *

    Vy is a fourth year Ph.D. student in the Neurosciences Graduate Program. In undergrad, she decided to create a Cognitive Science major to supplement her Biology major after realizing she had accidentally taken most of the relevant coursework (just because it was cool and interesting). She graduated from Swarthmore College in 2011 and moved to Rochester to do research with Dr. Jessica Cantlon on numbers, metacognition, and math in children and adults. Now she is interested in understanding neural coding in sensory systems and how this information is used in a variety of cognitive behaviors. In her spare time, she pursues various domestic geek hobbies (knitting, sewing, etc.), picks up heavy stuff, and sometimes writes. Here is Vy's CV.


    Chaipat Chunharas, M.D.

    Chaipat is a third year Ph.D. student in the Psychology department. Before that, he was a neurologist in a university hospital in Thailand. Learning and teaching neurology gave him a chance to help others and (some) understanding of how the brain works, however, he found far more questions than answers. He then decided to come to UCSD and spend a year working with Prof. Eric Halgren studying visual perception (esp. face perception) by various intracranial recording techniques (e.g. macroelectrode, laminar recording, Utah array). He is interested in studying perception, multi-sensory integration, illusions using multimodal approaches namely psychophysic analysis, electrophysiology, fMRI, rTMS and lesion studies. Even though he has not yet found all of the answers, he enjoys science, sunny beaches, seals, his first baby, and lovely friends.


    Nuttida Rungratsameetaweemana

    Nuttida is a third year Ph.D. student in the Neurosciences graduate program. She earned her B.S. in Neuroscience and Mathematics from Middlebury College in 2014, where she worked with Dr. Jason Arndt on how emotional arousal affects the encoding and consolidation processes of visual memory. Now, she is interested in understanding how visual attention and expectation influence decision-making. She enjoys playing bridge, running, drawing cartoons, and meeting new people, especially those who can sit still for hours with small eye blinks in the EEG room.


    Maggie Henderson

    Maggie is a second year Ph.D student in the Neurosciences graduate program at UCSD. She earned her B.S. in Biological Sciences from Cornell University, where she worked in Dr. Rob Raguso’s lab, studying the behavior of a tiny parasitoid wasp species (T. ostriniae). Now she is interested in using tools such as fMRI to understand how neural computations support human perception, particularly in the visual system. When she’s not working, Maggie enjoys running, cooking, drawing, and making origami.


    Anna Shafer Skelton

    Anna is a first-year student in the Psychology Department. She earned her B.A. in Philosophy-Neuroscience-Psychology at Washington University, where she worked with Dr. Richard Abrams. In the Harvard Vision Lab, she worked with Drs. Tim Brady and George Alvarez . She also worked as a lab manager in Dr. Julie Golomb's lab, where she explored visual processing across eye movements. She is currently interested in the content and temporal dynamics of short-term memory representations, as well as how different aspects of natural scenes may be remembered across eye movements. In her spare time, although she's become sidetracked from her goal of learning to surf, she has found many other fun things to do: drinking coffee, running, learning things on Duolingo, and more recently, board games.
