Sebastian Lopez

My research investigates the implementation and limitations of dynamic systems of attention to explain the human sensory experience. Using neurophysiological tools like electroencephalography (EEG), I study how the brain accesses, communicates, and models sensory information. I strive to ground traditionally abstract topics, such as consciousness, awareness, and agency, within a physically plausible framework.

Sebastian comes to us from Steve Luck's lab at UC Davis and has already presented at international conferences!

Wendy Alfonso Torrens

My research focuses on contributing to the understanding of the neurobiological mechanisms underlying the sensory experience of individuals with schizophrenia and autism. I also strive to improve neurophysiological methods (e.g., electroencephalography) by developing more racially inclusive materials.

Wendy was awarded a GRFP from the NSF to examine (and design) hair clips for EEG to make electroencepahlography accessible for ALL hair types. This work is already preregistered https://doi.org/10.17605/OSF.IO/AXU2C and will be updated with tools and information as the project progresses.

My research interests include exploring the mechanisms behind our sensory systems that permit complex perception of the world around us. By examining the limits of our visual and auditory systems, we can begin to paint a clearer picture of how various stimuli shape our environmental perception.

Specifically, my current project investigates how sensory sensitivity changes over the migraine cycle with the aim to identify biomarkers that signal approaching migraine-onset. While there is a lot of variability across migraineurs, a common symptom is sensitivity to light (photophobia) and/or sound (phonophobia). Using electroencephalography (EEG), electroretinography (ERG), and auditory brainstem response (ABR), my research contrasts the effects of sensory stimuli on migraineurs and headache free individuals from the retina and brainstem to the visual and auditory cortices.

    Cooper Chavez

    Hi! I’m a freshman at UNR studying Microbiology & Immunology with additional interests in Neuroscience and Psychology. I’m especially fascinated by cognitive variability and the ways individuals differ in how they perceive and respond to their environment. I’m grateful to be involved in undergraduate research through the PREP program, where I’m learning how to ask scientific questions and develop the skills to answer them under mentorship. My long term goal is to practice medicine while contributing to research that benefits vulnerable and underserved populations. Outside of academics, I love to rock climb, ski, and spend time with my family.


    Marcos Moreno Cervantes

    Hey, my name is Marcos Moreno Cervantes. I am a Freshman at the University of Nevada, Reno, majoring in neuroscience. I love learning about the mind and finding ways to use that information to optimize my life. Along with this, I enjoy weightlifting, cinematography, and mixing music during my free time. I have no background in research but recently got accepted into PREP with Dr. Haigh as my mentor. I aspire to become a psychiatrist, where I will gain a better understanding of the mind and body to not only help those with psychiatric disorders but also neurotypical individuals.


    Sidney Hulsey

    Hi! I am a junior at the University of Nevada, Reno studying Neuroscience with a minor/certificate in Gerontology. Previously, I worked in Dr. Piantadosi’s Computation and Language Lab for a summer studying psychophysical modeling techniques for approximate number tasks. My research interests are in sensory processing and neurodevelopmental disorders. I love working with students on campus with IDDs and other disabilities with the P2I and TAPDINTO-STEM programs. After graduating, I plan to apply to an M.D.-Ph.D. program where I can further pursue my interests.

    Sid is currently funded by the ENDURE program
