People with high level of nearsightedness will have a 5- to 10-fold chance of developing glaucoma, cataract, and sight-threatening diseases such as retinal detachment later in life. Atropine eye drop is one of the most effective therapies for nearsightedness control. I will conduct a small-scaled randomized controlled trial to understand the impact of eye color on the effectiveness of atropine eye drop. Many studies on atropine have focused on Asian populations, and few studies have compared the effect of atropine between Asians and Europeans, who tend to have much lighter […]

Up to half of Wilsons disease patients suffer from sleep disorders, including poor sleep quality, REM behavioral disorders (RBD), and cataplexy. However, the neural basis of these symptoms is poorly understood. My project this summer is to determine whether the ATP7B-/- knockout mouse is a good model system for studying the sleep disorders manifested in Wilsons disease, especially in the context of neural pathways involving copper homeostasis. Using automated sleep scoring methods, we will quantify sleep signatures in ATP7B-/- knockout and wildtype control mice. The brain copper changes in recorded […]

  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. […]

  In humans, Positive Transcription Elongation Factor b (P-TEFb) is an RNA Polymerase II regulator crucial for proper gene expression. To execute its regulatory function, P-TEFb itself is precisely regulated via reversible interactions with an snRNP complex. Using biochemical techniques, past studies have confirmed LARP7, HEXIM1, and BRD4 to be protein partners of P-TEFb. My project aims to study the dynamic regulatory role of known protein partners LARP7, HEXIM1, and BRD4 in P-TEFb regulation. I will apply a new technique called proximity-assisted photoactivation (PAPA) to single particle tracking (SPT) and […]

  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 […]

Glioblastoma (GBM) is the most common and lethal primary brain tumor in adults. Although research has enhanced GBM diagnosis and clinical stratification, overall patient outcome has not significantly improved. This is because GBM is incurable with current treatments, which include surgery, radiation therapy, and Temozolomide (TMZ) chemotherapy. The development of CRISPR-Cas9 systems presents opportunities to study human diseases, and it can be leveraged to create therapeutics. Specifically, CRISPR interference (CRISPRi)-based screens help study GBM dependencies and growth vulnerabilities without DNA damage. I have assisted with in vivo and in vitro […]

The spotted fever group Rickettsiae (SFGR) are a collective group of Gram-negative obligate pathogens from Rickettesia spp. Most bacteria in the SFGR use two effectors to mediate actin-based motility (ABM). This is in contrast to other intracellular pathogens, which utilize only a single effector for ABM. The goal of my research project is to understand how Rickettsia parkeri, a member of the SFGR family, regulates the expression of two effectors that mediate ABM: RickA and Sca2. While both effectors are involved in mediating ABM, the regulation for both effectors and […]

Memories in the brain are encoded in specialized neurons called “engram cells,” which are active during an initial event and the recall of that event. Little is known about how these cells form, but exposure to traumatic stress has previously been linked to an increase in the number of engram cells. The goal of my research is to examine the formation of engram cells in multiple areas of the brain after exposure to stress and determine if the increased presence of these cells results in PTSD-like behavior in mice. Understanding […]

Traumatic brain injury (TBI) and strokes are ongoing public health crises, taking millions of lives annually and leaving survivors chronically disabled. They commonly affect the orbitofrontal cortex (OFC), an integrative center for the brain’s reward and decision-making circuit. Thus, damage to the OFC can cause behavioral deficits, including impulsivity and impaired decision-making. My research examines the brain’s capacity for compensatory and functional reorganization in intact tissue following injury or lesion, which is crucial to furthering the clinical potential of neurorehabilitation. Previous analyses done by the D’Esposito Lab have found that […]

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 […]
