Human Adaptation to Simulated Central Vision Loss"
This summer, I’ll be conducting a study with the Sight Enhancement Lab at Berkeley that simulates the type of vision loss associated with macular degeneration, and tracks how human subjects with normal vision adapt to simulated central vision loss. We use a gaze-contingent display to present a gray circle on a computer monitor that moves with the subject’s eyes, thus blocking out visual information on the display according to where they are looking. Subjects wear a head-mounted binocular eye tracker that follows and records gaze positions continuously. Our interest is to track, over time, how humans adapt to central vision loss by adopting a preferred peripheral location as their new reference of vision....Read More about Kat Bako
Youth Participatory Action Research Systematic Review"
Youth Participatory Action Research (YPAR) is a form of community-based research where youth are trained to be active researchers in order to address the problems that impact them the most. This summer, I will primarily be continuing my work on a systematic review where we are looking at YPAR studies from the past few years and synthesizing how these projects have impacted youth and their communities. I will be working on qualitatively coding articles to categorize key findings and analyze various youth outcomes. Our goal is to identify what programs and methods effectively promote change and to understand how youth voices can be better prioritized and uplifted....Read More about Sakina Bambot
COVID-19 and Child-Directed Speech"
The COVID-19 pandemic has brought about new changes and considerations to our daily lives. The purpose of this project is to study the day-to-day routines of parents and their young children during this unprecedented time. Participants fill out short surveys and submit audio recordings of their child’s bath time for 30-60 days. From this data, we hope to analyze how families’ routines have been affected by the pandemic....Read More about Madelyn Bernstein
Investigating ecological trends in the Phillips Coal Ball Collection"
This summer, I will be continuing my work in transcribing and analyzing data from the Phillips Coal Ball Collection (PCBC). The PCBC contains taxa, tissue, and organ data from the analysis of 800,000cm2 of fossilized Pennsylvanian plant material collected from 17 different localities. I will continue to investigate the correlation we found in ecological dissimilarity between these localities across space and time and look into unique trends between time slices....Read More about Sydney Booth
Preschoolers and adults infer novel social biases from causal difference-making evidence about social exclusion"
Recent research in social cognitive development suggests that preferences for particular social categories (e.g., race, gender, etc.) over others are present by the early preschool years (e.g., Perszyk et. al, 2019). However, the largely nonverbal sources of these early attitudes are unclear. This summer I will be researching the extent to which preschool-aged children can isolate which specific features of a group are causally relevant to the way that they are treated by others and which are not. Specifically, we want to see if kids are able to ascertain these inferences when given solely nonverbal evidence, in which the discriminatory behaviors taken against a particular individual are displayed through actions, rather than through words....Read More about Mackenzie Briscoe
Fuerte: School-Based Prevention Program Targeting Newcomer Latinx Immigrant Youth "
Fuerte is a school based program implemented in various high schools in the San Francisco school district. The program targets newcomer Latinx youth who have arrived in the U.S five years or less post arrival, who are at risk of experiencing traumatic stress. In particular FUERTE focuses on providing mental health resources to students and connecting them to the school’s wellness center and other resources necessary, as well as improving their social functioning, allowing students to meet other students from their school who share a similar story....Read More about Maria Calderon
Inferential methods for n-dimensional hypervolumes"
N-dimensional hypervolumes are a popular method of modeling ecological niches and functional diversity; for example, each axis in an n-dimensional niche represents an abiotic factor that is required for the survival of an organism. Many mathematical methods have been developed for constructing hypervolumes, but there are currently no methods for constructing confidence intervals or performing statistical tests. I have added inference methods to the r package “hypervolume” including a nonparametric multivariate test based on overlap statistics. I will be investigating the statistical properties of these methods compared to other nonparametric multivariate tests as well as exploring the applications of these methods in ecology....Read More about Daniel Chen
Effects of Kilohertz Transcranial Magnetic Perturbation on Cortical Excitability"
Non-invasive brain stimulation (NIBS) modulates neural activity through the application of electrical or magnetic fields to a targeted region of the scalp. While many NIBS methods have proven to be useful in research and clinical treatments, each method presents its own limitations. The goal of this project is to test the efficacy of a new NIBS device known as Kilohertz Transcranial Magnetic Perturbation (kTMP) which has the potential to surpass key limitations present in standard NIBS methods. By analyzing the effects of kTMP on motor output or behavioral tasks, we can better understand the facilitatory or inhibitory capabilities of the device and its potential for clinical application....Read More about Serena Chi
Hummingbird Dietary Preference for Fermented Nectar"
Frugivores and nectarivores are naturally exposed to low levels of alcohol within their diets as a result of fermentative yeasts. This research project explores the preference of Calypte anna (Anna’s Hummingbird) for varying concentrations of ethanol in nectar. We will be running binary choice tests to measure nectar consumption rates and investigate hummingbird behavior. This research may reveal the effect of alcohol in hummingbirds’ diets and give insight into human alcoholism....Read More about Julia Choi
Using fossils to better understand periods of global warming in Earth's past"
This project will consist of cuticular analysis of oak and sycamore leaves in order to more thoroughly discern the relationship between light levels and stomatal index of the leaf, which will help increase the accuracy of models that help us understand past environmental factors through morphological characteristics of fossil leaves. We are also planning to travel to Tennessee and Kentucky over the summer to collect samples from the Eocene Gulf Coastal Plain plant communities of the Claiborne formation, where we can use the morphological leaf characteristics to better understand the evolution of ecosystems in the early Paleogene, a period of long-term warming in Earth’s history. Warming in the early Paleogene was likely similar to current global warming patterns, and studying the flora response to long-term global warming could help us to predict the effects of global warming currently, as well as increase understanding of how the biota reacts to environmental […]...Read More about Josephine Christon

People select and manipulate their environments constantly to best fit the tasks they need to complete/support the cognitive and emotional states necessary. This summer, I will be assisting my research mentor in data collection and paper writing on acoustical experiences in the workplace and emotional expression in a space. This research can better architects, engineers, and the general public as we discover the ways occupants can use the spaces around them to increase comfort and productivity. I’m excited to help bring this research to fruition and gather insightful data that can better instruct design and building technologies in our built environments....Read More about Angela S Chung
Examining Transdiagnostic Effects of Extremes in Approach Motivation and Cognitive Control"
Much attention has been focused on dysfunction associated with high or low approach motivation, or with deficits in effortful control. Recent evidence suggests, however, that it is important to consider these two dimensions jointly. This project examines the transdiagnostic effects of extremes in approach motivation and cognitive control across self-report, behavioral, and fMRI measurements. This summer, I will continue to assist my mentor in behavioral data collection, recruitment, participant management, and assisting with fMRI data collection....Read More about Lauren Cohen
Effects of climate change on Sierra Nevada stream food webs"
This project examines how Sierra Nevada snow melt, which is predicted to occur earlier in the year in the future, may impact aquatic insect communities. Using experimental streams at the Sierra Nevada Aquatic Research Laboratory (SNARL), we are examining how community structures and food web dynamics respond to changes in low flow timing. This summer I will be performing stable isotope analysis of macro-invertebrate samples to identify shifts in food web structure and relate those dynamics to changes in community composition. This research is vital to understanding how freshwater communities and ecosystems will respond to climate change....Read More about Ashley Cowell
Stability Driven Interpretation of Low-rank Compression Methodologies for CNNs"
Deep neural networks achieve state-of-the-art performance in many tasks such as computer vision and natural language processing, however many compression/acceleration methods for these models yield unstable or unreliable results. As such, I am using statistical methodologies to investigate the properties of low-rank compression methodologies, with a particular focus on SVD-based compression. In particular, I am focusing on how SVD compression can be used in compression with various filter-level visualization methods (i.e. saliency based methods) in order to reveal the internal “decision-making” structure of particular sections of these highly complex models. This will hopefully yield insights into how these compression methods could be used for the visualizations and interpretation of Neural Networks, something that is particularly relevant since utilizing “Black Box” algorithms poses a significant ethical dilemma in fields like medicine....Read More about Shiladitya Dutta

This summer I will help with the final preparations for a new exhibition at The Magnes Collection of Jewish Art and Life. The exhibition, Time Capsules. The Magnes: 10 Years at UC Berkeley, celebrates 10 years since UC Berkeley acquired the Magnes and will display objects featured in exhibitions from the last 10 years. I will be helping to edit exhibition labels and increase community engagement with the objects. I will also begin helping with plans for an exhibition in Fall 2022 about Jewish and Islamic art....Read More about Zoe Forest
Understanding Youth Empowerment Through Program Evaluation, Curriculum Planning, and Scholarly Writing"
The Youth Advocacy Program (YAP) recruited, developed, and evaluated a High School Outreach Series to teach youth about child marriage and how they can become advocates for child marriage prevention. After a year of successful workshops, I look forward to synthesizing evaluation efforts into informational sheets and data visualizations that can be disseminated to potential donors and stakeholders. I will be working with Dr. Deardorff on developing a theory of change model for the program, and Dr. Prata on writing a brief that distills information on youth empowerment and child marriage. Finally, in collaboration with other Youth Equity Scholar (YES) students and Dr. Schotland, I will be analyzing post program data and addressing feedback as we develop the curriculum for next year’s YES cohort....Read More about Arpna Ghanshani
Developing and promoting the psychological humanities"
It involves a book, for Palgrave Macmillan, due out later this year, which explores what the emerging interdiscipline of the psychological humanities offers to psychology practice and models of human subjectivity. It also includes developing and delivering a course for students within the interdisciplinary field of Women’s and Gender Studies at Cal, which is due to be expanded to Cal State East Bay later in 2021. The psychological humanities has developed out of critical psychology, and recognizes that the psy-disciplines (psychology, psychiatry, psychoanalysis and psychotherapy) are human sciences, not STEM sciences. It looks to apply critical theories about culture and human meaning developed in the humanities to how the psy-disciplines think and function....Read More about Hannah Hanson
Understanding the relationship between multiple infections of symbionts and how they affect the microbiota"
In nature, infections that consist of multiple parasite strains are common and are of major public health concern. Theory suggests that these infections have a huge influence on the evolution of infectious diseases. Recently, there has been growing interest in what shapes taxa moving from mutualist to parasite. The goal of my research is to explore this question and look at the relationship between multiple infections of symbionts, in particular non-pathogenic bacteria. Understanding these key interactions will help explain the complicated workings of the transition of microbiota from commensals to bacteria....Read More about Joy He

Over the summer, I hope to continue my work with dielectrics, begin working on simulating radiation detection applications, and assist Dr. Waqas Khalid in any other roles he may need....Read More about Benjamin Heronimus
anti-DENV and anti-ZIKV immunity interactions"
Dengue and Vika virus are mosquito-borne flaviviruses common in tropical and sub-tropical areas that can result in a range of clinical manifestations, from a self-limited dengue fever to a potentially fatal dengue shock syndrome (DSS) caused by vascular leakage. This summer, I will be researching anti-DENV and anti-ZIKV immunity interactions using a Luminex system to determine which serotypes are correlated with primary inapparent infection of Dengue. My personal focus is on domain III of the envelope protein of DENV 1-4 and ZIKV, a domain known to bind type-specific antibodies. By analyzing the binding profiles of type-specific and cross-reactive antibodies, I will be able to better understand the profiles of a combination of sequential infections, and better predict how to develop and evaluate Dengue and Zika virus vaccines....Read More about Julia Huffaker
