Projects for the 2025-2026 application have now been updated, see below!
Not sure where to start? Fascinated by many different aspects of neuroscience? We have organized our projects into four typical neuroscience research areas, although projects can occupy multiple research areas.
Cognitive research focuses on connecting processes of the mind with the nervous system.
Computational research generally includes statistical and mechanistic modeling of cognitive processes, nervous system connectivity, and neural activity.
Circuits/systems neuroscience is concerned with the connectivity of different brain regions and neuronal types.
Molecular/cellular neuroscience is the study of cell biology, biochemistry, and structural biology within the context of the nervous system.
Within these four areas, projects can entail "wet lab" or "dry lab" research, corresponding to hands-on experimentation or computationally-focused research, respectively. If you are interested in any particular techniques/skills, this may help you narrow down your choices, and we indicate the orientation of the research in each project. Feel free to contact us if you have any further questions.
Cognitive Projects 🧠
🧠Walker Lab: Sleep, Memory Loss, and Neurodegeneration
2025-2026
Classification: Dry lab
Project Description: Our lab studies how sleep supports brain health across the adult lifespan, with a focus on aging and Alzheimer’s disease. We use non-invasive tools like EEG, fMRI, and PET to explore how brain activity during sleep helps clear waste, strengthen memory, and maintain cognitive function. We’re especially interested in slow waves during non-REM sleep and how they relate to memory loss and neurodegeneration. Our research combines cutting-edge brain imaging with behavioral testing to understand individual differences in sleep and cognition. Students will gain exposure to neuroscience techniques, data analysis, and the opportunity to contribute to ongoing discoveries in human sleep science.
REP Student Main Contribution: Data Collection & Analysis.
Students will begin by assisting with data collection in human sleep studies, including EEG and fMRI setup, behavioral tasks, and participant interaction. This hands-on experience will provide a strong foundation in research protocols, neuroimaging techniques, and study conduct. Depending on their background and interests, students may also participate in data analysis, including sleep staging, signal processing, or cognitive performance metrics. We aim to tailor the experience to each student's goals and provide mentoring in scientific thinking, collaboration, and career development within neuroscience.
🧠Ivry Lab: Cognition and Motor and Reward Learning
2025-2026
Classification: Dry lab
Project Description: In this new project we are going to be investigating how humans acquire new skills both at the behavior and neural (fMRI) level. Specifically, we are using an ecologically valid task (video game: Stardew Valley) to collect high-dimensional data while people perform a range of cognitive "tasks" from motor to reward to cognitive control. There will also be visual and auditory info (eye tracking and sound track) collected - should these lower-level processes be of interest to a prospective REP student!
REP Student Main Contribution: Data Collection & Analysis.
The student will be primarily responsible for coordinating behavior data collection in-person. As we collect data the student will also help check data quality and help run analyses and potentially start their own new analyses, depending on how the project is going.
Computational Projects 💾
💾Ivry Lab: Language, fMRI, and Computational Modeling
2025-2026
Classification: Dry lab
Project Description: The goal of this project is to understand the role of the cerebellum in semantic processing. We will have cerebellar degeneration patients and healthy controls participate in an analogy task to probe semantic reasoning. We will then computationally model the behavior using natural language processing and other data science techniques between the cerebellar group and neurotypical group to determine potentially computational roles of the cerebellum in semantic processing. We also hope to collect limited structural and functional MRI data to further map this question.
REP Student Main Contribution: Data Collection & Analysis.
The primary initial responsibilities will be for the student to help organize and collect behavioral data. Additionally, students would help transcribe and temporally align the behavioral and fMRI data to prep it for analysis. I expect this to be able to be completed (with help) by the end of the first semester. From there I would plan to work with the student to develop a sub research question they are most interested from the available data to develop an analysis.
Circuits/Systems Projects 🖇️
2025-2026
Classification: Wet lab
Project Description: We are investigating the mechanisms of synaptic plasticity that support spatial navigation and memory, using fruit flies as a model system. In the center of the insect brain, a ring-shaped structure called the Ellipsoid Body computes the animal’s orientation in its environment. Much like the needle of a compass, a bump of increased neural activity circles around the ring as the fly turns. Synaptic plasticity between visually driven inhibitory neurons and compass neurons is required for the compass to maintain an accurate representation. This project is focused on elucidating the mechanisms of this plasticity at multiple levels.
REP Student Main Contribution: Data Collection & Analysis.
The student will be potentially responsible for a broad range of tasks supporting the overall goals of our scientific questions including creating transgenic flies, immunohistochemistry, confocal microscopy, two photon microscopy, electrophysiology, building experimental rigs for fly behavior, data analysis, computational modeling, etc. The specific responsibilities can be tailored somewhat to the students interests.
2025-2026
Classification: Wet lab
Project Description: An animal's sense of 'heading,' or the direction it's facing in the world, is computed within neural circuits that use information about body movement and environmental cues. In Drosophila, the 'compass network' does the task of relating environmental cues (for example, the position of the sun) with a stored neural representation of heading. Two well-known neuromodulators, dopamine and serotonin, are both predicted to signal within the compass network. Dopamine has been shown to promote plasticity in the network, but a role for serotonin has yet to be described. To better understand the functions that each of these neuromodulators play in the circuit, their targets need to be identified: specifically, which classes of neurons in the compass network express which receptors for serotonin and dopamine.
REP Student Main Contribution: Data Collection & Analysis.
A student working on this project will perform fluorescence in situ hybridization (FISH) and/or immunohistochemistry (IHC) on Drosophila brains. This entails maintaining fly stocks, setting up fly crosses, dissecting fly brains, processing fly brains with FISH/IHC (fixing, staining), and finally imaging the brains using a confocal microscope. In addition to wet lab work, students will meet regularly with the mentor to check-in with the project and conduct literature reviews to understand the project background.
2025-2026
Classification: Wet lab
Project Description: My project aims to elucidate mechanisms underlying psychedelic effects on anxiety and compulsive-like behaviors. Stress disorders, for example PTSD, are associated with compulsive behaviors, but the brain mechanisms linking stress exposure to compulsive behaviors, and the effects of psychedelics on them, as well as the brain at baseline, are not well understood. I pursue the hypothesis that myelin plays a role in psychedelic effects on anxious and compulsive behaviors through adaptive myelination. This work illuminates myelin plasticity’s role in psychedelic effects on these behaviors, and provides insights on future therapeutic targets focusing on the reversibility of posttraumatic structural brain changes.
REP Student Main Contribution: Data collection and analysis.
Major student responsibilities include, slicing and cryo-preserving brain slices, immunohistochemistry and subsequent analysis of scanned images for fluorescence intensity. Other responsibilities include assisting in collecting animal behavioral measures, assisting in brain collections, and assisting with statistical analyses of collected data. Students are expected to be proactive in their position, learn and perform techniques as taught, work with a team, and provide consistent communication with their supervisor.
2025-2026
Classification: Wet lab
Project Description: Our sensory perception is shaped by the integration of inputs from multiple points of the surrounding space. We will probe the neural activity evoked by multi-whisker inputs within the primary (S1) and secondary (S2) somatosensory regions of the cerebral cortex during a tactile target detection task in the mouse model. Throughout task performance, responses to sensory stimulations will be recorded using a dense electrocorticography (ECOG) array, which offers a readout of individual and multiple whiskers’ cortical representation. Our objective is to relate electrophysiological characteristics of multi-whisker integration to the animal's performance in detecting these stimuli.
REP Student Main Contribution: Data collection and analysis.
The primary student responsibilities will be to train mice to perform a tactile driven task that is well established in the lab, collect behavioral data. The student will analyze behavioral data under supervision (prior coding experience is preferred but not required). The student is expected to actively engage in critical thinking about the experiments by reading scientific articles, attending meetings with the supervisor and other students, and demonstrating an interest and/or curiosity in the topic.
Molecular/Cellular Projects 🦠
2025-2026
Classification: Wet lab
Project Description: Identifying the synaptic mechanisms that maintain neural stability while allowing for the plasticity needed for learning remains a paramount challenge in neuroscience. Of critical relevance are the long-lasting plasticity effects of psychedelics, which are experiencing an explosion of scientific visibility surrounding their potential to treat psychiatric disorders. Despite rising clinical interest, we currently lack an understanding of how a single psychedelic dose drives long-term changes in the brain. Our lab aims to fill this gap in knowledge by investigating how a single psychedelic dose persistently modifies synaptic plasticity in the prefrontal cortex. This project specifically investigates the role of an inhibitory interneuron subtype in mediating these long-lasting plasticity effects.
REP Student Main Contribution: Data Collection and Analysis
Study existing literature to be able to participate in lab meetings, project discussions, and project development. Learn to perform various essential lab techniques: mouse handling, genotyping (tissue digestion, PCR, gel electrophoresis), immunohistochemistry/imaging, molecular biology techniques, etc. After successfully learning fundamental lab techniques, the student researcher will be invited to work on an independent project under the mentorship of the graduate student. The goal is for the student to develop skills in experimental design, data collection, analysis, and interpretation.
2025-2026
Classification: Wet lab
Project Description: How do neurons maintain stable communication when postsynaptic signaling is disrupted? This project investigates the mechanisms of presynaptic homeostatic potentiation (PHP), a form of homeostasis that compensates for reduced postsynaptic receptor function. Using Drosophila mutants lacking the glutamate receptor subunit GluRIIA—an established model of chronic PHP—we will test whether several proteins are required to sustain this homeostatic response. Through genetic manipulation, immunohistochemistry, GCaMP imaging, and intracellular electrophysiology, we aim to assess the roles of various proteins in regulating synaptic transmission under chronic PHP. Findings may reveal fundamental principles of synaptic stability relevant to neurodevelopmental and neurodegenerative disorders.
REP Student Main Contribution: Data Collection and Analysis
Students will perform larval dissections and immunohistochemistry to visualize synaptic proteins. Student will also assist with live imaging of GCaMP signals to monitor postsynaptic calcium dynamics and with intracellular recordings to quantify synaptic transmission. Students will also gain experience in setting up genetic crosses, designing experiments, collecting and analyzing data, and actively participating in lab discussions and problem-solving.
Past Projects
2024-2025
Classification: Dry lab
Project Description: Previously the lab has developed a paradigm to look at the effect of positive and negative feedback on timing behaviors. Previous results implicated the dmPFC and insula in encoding these feedback effects in a mixed manner, but in looking at the mesoscale LFP. In some cases, we had microwires, enabling us to get the activity of single neurons in this task in various brain regions (Orbitofrontal Cortex, Hippocampus, Anterior Cingulate, Amygdala). This project will look at the single neuron responses during this task and compare this to the LFP responses on the micro and mesoscale, focusing on mPFC to investigate the presence of task-relevant information at various spatial scales.
REP Student Main Contribution:
The student will be using a semi-automatic spike sorter to recover single unit spike trains from individual runs of the experiment for different patients. In addition, the student will implement some basic regression models to look for single neuron coding to positive feedback, negative feedback, and RPE and see if different trends hold for different brain regions. If time allows, the student will use population decoding methods to see if these task variables are more easily recovered on the global scale than on a single neuron scale.
Skills that you will learn:
Matlab (for spike sorting)
Statistics (Poisson GLMs, multiple comparison corrections)
Python coding (Handling Pandas dataframe and big numpy arrays using a server)
Neurobiology (Some neuroanatomy and basic understanding of how neurons transmit information)

2024-2025
Classification: Dry lab
Project Description: Can large language models (LLMs) like ChatGPT demonstrate human-like intelligence? Can we systematically and robustly evaluate the intelligence of LLMs like neuroscientists have done on humans and animals? Using a set of behavioral tasks that target broad cognitive abilities, we will evaluate LLMs to characterize their intelligence, providing a benchmark for future Al models and a deeper understanding of how artificial intelligence measures up to humans.
REP Student Main Contribution: The student will participate in data collection, which includes generating prompts, querying LLMs, parsing outputs, and streamlining the process. Depending on the student’s background and interests, they may also help with data analysis, visualization, and computational cognitive modeling of LLM and human behavioral data. No prior experience is necessary.
2024-2025
Classification: Wet lab
Project Description: Neural computations in sensory cortex occur rapidly within specific subnetworks and interact with cognitive signals in ways that remain unclear. Traditional neural imaging methods, lack the temporal resolution to capture fast neural activity changes. Genetically encoded voltage indicators (GEVIs) offer better resolution and can detect spiking activity and subthreshold potentials. This project has two main goals: First, to improve high-speed imaging of GEVIs using advanced optical and analysis methods. Second, to apply this method to study how sensory and cognitive signals interact in specific neural subtypes.
REP Student Main Contribution: Data Collection and Analysis
The primary responsibilities of this project involve behavioral training of mice to study how deviant or unexpected stimuli are processed in different contexts. This involves operant conditioning training and adjustment of behavioral parameters to ensure mice achieve expert level performance on the task. Additionally, a critical part of these experiments is related to determining the anatomical location of the neurons that were imaged during the behavior. This involves performing histological staining on ex vivo brain tissue. There are also opportunities to learn analysis of behavioral and neural data.

2024-2025
Classification: Wet lab
Project Description: Synaptic plasticity enables neural circuits to adjust the strength of synaptic connections between cells, refining circuit communication and behavior in response to changing inputs. Psychedelics induce plasticity in both humans and mice, and are currently in clinical trials to treat mood disorders like depression and anxiety.

2024
Classification: Dry lab
Project Description: All organisms have an internal sense of direction, called head direction, which is computed within neural circuits using information about body movement and external cues. Head direction in Drosophila is represented within the compass network, where Ring neurons represent visual features in the fly’s environment and directly shape head direction representation. Whole-cell patch clamp recordings (electrophysiology) have found that Ring neurons exhibit distinct firing patterns that include massive depolarizations referred to as bursts. The molecular and cellular mechanisms underlying Ring neuron bursts and how this unique firing property modulates information processing are unknown. Burst firing in mammalian neurons has been found to have various functions, including expanding stimuli encoding and facilitating synaptic plasticity. To begin to understand the functional significance of ring neuron bursts, work needs to be done to parameterize burst properties such as magnitude and duration. Developing a quantitative framework to analyze and categorize bursts will set the foundation for perturbation experiments to understand the molecular and cellular mechanisms underlying Ring neuron bursts.
REP Student Main Contribution: A student working on this project will be developing computational tools in Python to analyze electrophysiological data (i.e. voltage recordings). In addition to coding, students will meet regularly with the mentor to check-in with the progress of the project and conduct literature reviews to understand the project background. If interested, the student may also assist or shadow during aspects of the data collection process (patch clamp electrophysiology).
2024
Classification: Wet lab
Project Description: All organisms have an internal sense of direction, called head direction, which is computed within neural circuits using information about body movement and external cues. Head direction in Drosophila is represented within the compass network, where visual information is relayed from the retina through a multi-synaptic pathway. Previously, activation of the TuBu neurons in the pathway have been shown to result in an excitatory response in the downstream Ring neurons when using calcium imaging. The electrophysiological response of Ring neurons to TuBu activation is unknown, but nevertheless important in understanding visual information processing relevant for spatial navigation. The expression patterns of the genetic tools needed for this experiment are not well characterized. Immunohistochemical analysis of the driver lines used for this experiment is needed to understand the precise connectivity between neurons.
REP Student Main Contribution: A student working on this project will perform immunohistochemistry on Drosophila brains. This entails maintaining fly stocks, making fly crosses, dissecting fly brains, processing fly brains with immunohistochemistry (fixing, staining), and finally imaging the brains using a confocal microscope. In addition to wet lab work, students will meet regularly with the mentor to check-in with the project and conduct literature reviews to understand the project background.
