Dyllan Simpson - PhD student
Dyllan is a Ph.D. student in the Brady Lab interested in using computational modeling to predict ideal participant behavior for various cognitive and perceptual tasks. He is currently focused on visual long-term memory, including memorability and hybrid visual search tasks. He is also interested in how continuous psychophysics can be used to optimize data collection and explore individual differences. You can view his Google Scholar profile for more.

Junsong Lu - PhD student
Junsong is a PhD student who joined the Brady lab in 2025, having previously worked with Dr. Chujun Lin. He earned his M.S. in Applied Psychology from the Chinese University of Hong Kong, Shenzhen, and his B.S. from Northeastern University, China. He uses computational modeling at the intersection of judgment and decision-making and social cognition, and in our lab he is working on semantic networks while continuing his research on stereotypes and impressions. You can view his website for more.

Chattarin Poungtubtim - PhD student
Chattarin (Pun) is a PhD student in the Brady and Serences labs who joined the lab in 2025. He recently completed his M.D. from Chulalongkorn University, Thailand. He’s interested in studying how humans use memory to imagine, think and plan by using a combination of psychophysical experiments, neuroimaging techniques and computational modeling.

Mariagrazia De Gioia - Former visiting PhD student
Mariagrazia visited the lab for half a year in 2025-2026 as a visiting PhD student from the University of Bologna. In our lab, she worked on memorability and novelty. Here is Mariagrazia's website.

Yang Wang - Former PhD student
Yang completed his PhD in Psychology in 2025, co-advised in our lab and the Vul lab. He was interested in vision -- and in things other than vision, like how our visual systems shape our understanding of data visualizations. He was previously a UCSD undergrad majoring in Math and Psychology. Google Scholar profile.

Isabella DeStefano - Former PhD student
Isabella was a PhD student in the Brady lab interested in psychophysical scaling, individual differences and the role of categories in visual working memory. She was also interested in the role of chunking in memory, memory for symbolic number and computational models of memory. Here is Isabella's Google Scholar profile.

Malinda J. McPherson-McNato - Former postdoc
Malinda studies how listeners perceive and remember sound. She received her PhD from the Harvard/MIT Program in Speech and Hearing Bioscience and Technology and then postdoc-ed with us for 2 years. She's now a professor at Purdue. Website. Google Scholar profile.

Jamal Williams - Former PhD student
Jamal was a PhD student in the Brady and Störmer labs, working on a variety of issues at the intersection of visual memory and visual attention, including how visual working memory guides visual attention, the role of interference within a category on visual long-term memory, crossmodal recognition, and the role of knowledge in visual working memory. He is now an Assistant Professor in the Psychology Department at UC Santa Cruz, where he runs his own lab; you can learn more at his website and Google Scholar.

Maria Robinson - Former postdoc
Maria did her PhD at University of Illinois at Urbana-Champaign and then postdoc-ed with us for 4 years. She is now an Asst Prof at Warwick Univ. She combines empirical work and computational modeling to study visual cognition, decision making, attention and memory. Website.

Michael Allen - Former PhD student
Michael was a Ph.D. student in the Cognitive Science department, working between the Interactive Cognition lab and the Brady lab. He received his undergraduate and masters degrees in mathematical physics in Dublin, Ireland, before switching to psychology via a master’s degree in London, and finally arriving in UCSD. He was (and still is) interested in the intersection of memory, perception and the occurrent conscious experience, from a philosophical and psychological perspective. He is now a Lecturer in the Department of Cognitive Science at UCSD and co-owner of the vegan restaurant Evolution Fast Food. Here is Michael's Google Scholar profile.

Hayden Schill Hendley - Former PhD student
Hayden was a PhD student in the Brady lab and is now an Assistant Teaching Prof at UC Riverside. She was previously a research assistant with Dr. Jeremy Wolfe at Harvard Med. School and before that an undergraduate at Rhodes working with Jason Haberman. In Brady lab, she worked on how memory is impacted by expertise, in particular focused on how radiologists remember and make decisions about medical images. Here is Hayden's website.

Jonathan Keefe - Former PhD student
Jonathan was a PhD student in the Störmer and Brady labs interested in how perception and attention work within and across sensory modalities, using EEG to better understand the neural bases of these cognitive processes. He is now a Senior Applied Cognitive Scientist at Pacific Science & Engineering. Here is Jonathan's website.

Lauren Williams - Former postdoc
Lauren received her PhD from the University of Utah, where she worked with Dr. Trafton Drew. In the Brady and Stoermer labs, Lauren was interested in learning how prior knowledge and task context influence our mental representations of objects during complex visual tasks (e.g., visual search); the consequences of a limited visual attention system in applied settings, such as radiology; and perceptual expertise. She went on to become a UX Researcher at Google. In her spare time, she enjoys traveling to new places, listening to music, and hiking. Here is Lauren’s website.
