Machine learning classification is growing increasingly important for a variety of industries and applications, including medical imaging, spam detection, facial recognition, financial predictions, and more. As understanding of these systems advances, so do attacks which seek to exfiltrate information from exposed models. These models are often trained on confidential data and leakscan compromise user privacy. Additionally, users may wish to receive classifications on a modelwhile keeping their own input secret from the service provider. To address these concerns, I introduce the concept of secure prediction. Secure prediction defines a joint […]

The current treatment for cholera infection is hydration with sanitary water and salts to replenish the nutrients and water lost through diarrhea. The World Health Organization estimates that 120,000 people die each year from cholera infection alone, with the majority of deaths in developing countries which have neither the infrastructure nor resources to treat patients. Current vaccines are ineffective; therefore, researchers are turning to alternative ways to stop the spread of cholera. While trying to understand a unique genetic island that Vibrio Cholerae uses to protect itself from viral infection, […]

Finding the causal genetic basis of a complex trait is a challenge of biology. Current methods, such as GWAS and QTL analysis, can identify associations between variants and phenotypes, but this is limited to analysis within the species being investigated and not species-wide traits. Through a novel approach named RH-seq (reciprocal hemizygosity analysis via sequencing), causal variants that underlie interspecific differences can be identified, including those that are the basis of adaptive evolutionary changes. I will be investigating the genetic basis of the relative thermotolerance of Saccharomyces cerevisiae (budding yeast) […]

The main goal of my project is to understand, genetically, how differences in heart rate have evolved such that large mammals have slower heart rates than smaller mammals. So far, I have found strong evidence that the activity of the pacemaker ion channel HCN4 in the sinoatrial node (SAN, the hearts natural pacemaker), correlates with the resting heart rate of different species. My central hypothesis for this heart rate scaling phenomenon is that differences in heart rates among different mammalian species are partially determined by sequence changes at HCN4 enhancer […]

Gadolinium-based contrast agents (GBCAs), consisting of a chelating agent and gadolinium metal (Gd(III)), have been used to enhance magnetic resonance imaging (MRI) contrast for the last 30 years, with over 300 million procedures to date. Because of the electronic magnetic moment of the gadolinium and nearby water molecules, gadolinium can be imaged accurately when exposed to strong electromagnetic fields like those created by MRI machines, improving the image clarity of the bodys structures. Accurate diagnosis scans allow for the detection of inflammation, tumors, blood vessels, and blood supply, all of […]

Pancreatic cancer is one of the deadliest cancers nationwide, due to the dearth of effective treatment options. While KRAS oncogenic mutations are ubiquitous in pancreatic cancer, there is no anti-KRAS therapeutic for routine clinical use. One promising alternative may be boron neutron capture therapy (BNCT), which entails the irradiation of internalized boron atoms in cancer cells. In particular, carborane compounds are clinically promising for serving as effective cytotoxic BNCT agents. Therefore, I propose to improve upon current carboranyl molecules to develop a highly boronated dendrimer which will be conjugated to […]

In invertebrates and humans alike, the nervous system fundamentally serves to detect sensory inputs and generate appropriate behavioral outputs. However, despite its ubiquity, our understanding of how this phenomenon occurs at the level of single neurons is far from complete. In the insect model Drosophila melanogaster, previous studies have provided some insight into how neural circuits govern various simple behaviors. For example, populations of neurons have been identified that control feeding and drinking – homeostatic processes conserved among a wide range of organisms. However, how this circuitry is modulated to […]

The introduction of fluorinated moieties into pharmaceuticals can often predictably improve the lipophilicity, metabolic stability, and the conformation of drugs. A fluorinated functional group of interest is the (Z)-fluoroalkene, a non-hydrolyzable isostere for peptide bonds. Many methods used to prepare fluoroalkenes, including Wittig-type olefinations, Shapiro reactions, and bromofluorination/elimination reactions often provide olefins in low stereoselectivity. Herein we will present a copper-catalyzed SN2 substitution of fluoroalkylated alkenes to prepare a variety of (Z)-fluoroalkenes in excellent stereoselectivities.

Cell division is a highly regulated process through which organisms generate new cells. From a single fertilized egg, a whole organism is developed after many cell divisions have occurred. Since the majority of these divisions are mitosis, errors in mitosis can cause lethal embryos due to loss of genetic material. Therefore, it is crucial for a mitotic cell to propagate the genome faithfully. My research focuses on the machinery that distributes the genome during cell division. This machinery includes the kinetochore, the protein complex that connects chromosomes to microtubules during […]

The physical organization of chromatin in the nucleus plays a crucial role in the coordination and regulation of gene expression. Long-distance interactions between DNA regulatory elements called enhancers and promoters are important for establishing cell type-specific gene expression programs. Dysregulation of enhancer-promoter interactions can lead to aberrant gene expression and thus promote developmental abnormalities and tumorigenesis. Yin Yang 1 (YY1) is a ubiquitously expressed transcription factor in mammalian cells that has recently been implicated in coordinating enhancer-promoter interactions, thus facilitating transcription activation during embryonic development. However, it remains unknown how […]
