Algebraic geometry is a rich area of mathematics that investigates the properties of geometric objects (like a variety the solution set of a system of polynomial equations) using their underlying algebraic structure. The closely related field of homological algebra studies how mappings between algebraic spaces (e.g., collections of polynomials) can be understood in terms of more concrete representations with tools from topology and algebra combined to understand the geometric structure of varieties. One homological invariant is a table of numbers called the Betti table, which captures nuanced geometric information about […]

In arthropods and vertebrates, Hox genes determine how an organism develops along the axis running from its head to its tail. Little is known of Hox function outside of these standard animal models, but studies in annelids (segmented worms) suggest that Hox genes not only play a conserved role in embryonic patterning, but are also deployed in ways specific to annelids. For example, hox3 is expressed around the posterior growth zone (PGZ), from which all new segments arise. I hypothesize that hox3 is a stem cell marker in annelids that […]

  Cataract, a clouding of the eye lens, is the leading cause of blindness worldwide. Periaxin (Prx) is a scaffold protein interacting with membrane/cytoskeletal networks in the lens and other cell types and has been implicated in cataract development. My project will investigate the functions of Prx variants in lens cells. Recent studies in the Gong Lab suggest that Prx is a genetic modifier regulating cataract severity in connexin 46 knockout (Cx46KO) mice. Four Prx missense variants have been identified between the 129SvJae (129) and the C57BL/6J (B6) mouse strains. […]

  Psychedelics have been used medicinally for thousands of years by Native Americans, but research into their clinical effects and mechanisms was prematurely halted in the 1960s. Exploration of the effects of psychedelics is long overdue. Recent studies have found that single doses of psychedelics can have positive, long-lasting effects, but very few studies examine psychedelic effects on behavior. My project aims to discover how psychedelics influence associative learning behavior. Associative learning involves learning the association between a cue and an outcome. I hypothesize that mice treated with psychedelics will […]

Geometric flows, such as the Ricci flow, Yang-Mills flow, and harmonic map flow, are natural ways to smooth out geometric objects (metric, connection and maps, respectively). In this research project, we will explore the idea of using geometric flows to develop new analytic tools for studying geometric objects. A possible goal of this project is to use geometric flows to solve problems in dispersive PDEs that involve geometric objects.

This research project examines the rich history and future of midwives of color in the Bay Area through the novel implementation of Science, Technology and Society (STS) frameworks. By defining the midwifery model of care conceived by Bay Area midwives of color as a complex sociotechnical system, the process by which midwives of color have created their models of care can be explored at the intersection of the nation’s capitalistic healthcare system, historic attempts to destroy the knowledge produced by grand midwives in the antebellum period and broader African diaspora, […]

Suppose that we have a (finite or infinite) series of independent, identically distributed real-valued random variables (increments of time). From this series, we can form a random walk. We can consider the partial sums of this series and analyze the average value of the walk the partial sum divided by the number of increments up to that point at each of its time increments. This project is focused on studying the distribution of the maximum average value of a random walk through a variety of computational algorithms. While there already […]

The stable isotopic composition of marine carbonates is an exemplary standard for reconstructing past Cenozoic climate. But, a fundamental question is whether these carbonates faithfully record their original isotopic composition, and to what extent have they been modified during burial. The relative abundance of isotopologues of carbonate with two rare isotopes (clumped isotopes) is a function of formation temperature and is leveraged to understand how carbonate samples were formed and modified through time. Recent work to reconstruct paleotemperatures from carbonate clumped isotopes found that samples from below 1,000 meters below […]

The devastation caused by intensifying wildfires in California over several decades has had increasingly detrimental effects on the diversity of native vegetation and the soil microbiome, which are critical in shaping plant growth and function. However, we still know very little about how native soil microbiomes are affected by wildfire and their role in host plant recovery. Specifically, we do not know how soil microbiomes of California grasslands (which evolved with periodic, low-intensity fires) mediate the recovery of native vegetation and how they may interact with non-native plants. As both […]

The ability to reliably leap and land on unfamiliar and unstable surfaces is instrumental to squirrels’ survival and navigation of arboreal environments. In previous studies, squirrels quickly learned to modify impulse generation upon repeated leaps from unfamiliar, compliant beams and rapidly adjusted foot placement to compensate for rotating rods. Understanding how squirrels adjust to unexpected landing conditions could not only help us better understand their morphological adaptations but could also provide innovative solutions in developing bio-inspired robots. Current jumping robots, such as UC Berkeley’s SALTO, are only capable of using […]
