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


    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 page and her CV.

    Stephanie Nelli #

    Stephanie is a fifth 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 fifth 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. Her hobbies include knitting, listening to podcasts, and rock climbing. Here is Vy's CV and her webpage.


    Chaipat Chunharas, M.D.

    Chaipat is a fourth 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 fourth 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 third 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 second-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.


    Angus Chapman

    Angus is a first-year student in the Psychology department. Originally from New Zealand, he received a BSc and BSc (Hons) in Psychology and Statistics from Victoria University of Wellington. There he worked with Dr. Gina Grimshaw studying how attention and cognitive control interact with emotion, and with Tirta Susilo studying how we perceive and recognize faces. At UCSD, he hopes to learn more about the neural mechanisms that underlie perception, attention, and working memory, and how these processes are involved in constructing our perceptual experience. Outside the lab, Angus listens to too many podcasts about TV and politics, occasionally swing dances, and tries to learn how to speak like an American.
