Former Ballet Dancer → Future Physician Scientist

My biomedical research is centered on viral diseases. While I no longer dance professionally, I coordinate research focused on understanding disparities and long-term outcomes in ballet.

I aim to combine skill sets in virology, medicine, and data science. I am currently doing my PhD in Dr. Pei-Yong Shi’s lab where I work with SARS-CoV-2.

Interests

Most of my current work uses reverse genetics systems and in vitro models to characterize cloned virus mutants. The Dr. Pei-Yong Shi lab uses this approach to study drug resistance in support of novel therapies, viral evolution in the context of emerging variants, and how protein structure relates to function.

Recombination is an essential driver of virus evolution and adaption, giving rise to new chimeric viruses, structural variants, sub-genomic RNAs, and Defective-RNAs. Next-Generation Sequencing of virus samples, either from experimental or clinical settings, has revealed a complex distribution of recombination events that contribute to the intrahost diversity within individual hosts. This diversity has been associated with viral persistence, immune evasion, and termination of infection in different contexts.

I am working with Dr. Andrew Routh to standardize and expand the detection of non-homologous recombination in viral sequencing data. So far, this has involved making a point-and-click analysis tool in Shiny and containerized versions of the detection software ViReMa. We are working to increase the breadth of ViReMa-compatible sequence data and apply it to publicly available data sets on the Sequence Read Archive. This will enhance the discovery of such events, allow correlation with disease-relevant outcomes, and enable exploration of intrinsic properties of recombination across virus families, conditions, and time points.

Viral infections of the central nervous system (CNS) have a wide spectrum of clinical severity. While some viruses can cause profound architectural and behavioral changes, others are asymptomatic or cause subtle cognitive deficits.

Modeling infections of human brains is greatly potentiated by organoid technology. My work with the Dr. Ernesto Marques and Vishwajit Nimgaonkar labs used cortical organoids to investigate HSV-1 and Zika virus infection. For Zika virus, we explored changes in the complement system upon CNS infection as complement has an important role in neurodegeneration, neuro-development, and synaptic pruning. In order to recapitulate complement protein production in the brain, we used a non-organoid culture model to inform the development of a pluripotent stem cell derived model that would more accurately reflect expression profiles seen in humans. We also studied changes in complement production and surface-bound modulators after Zika infection.

With Dr. Pei-Yong Shi’s lab, I am currently investigating the impact of SARS-CoV-2 infection on brain organoids and potential connections to Long COVID.

Becoming a professional ballet dancer is an extremely competitive endeavor. Navigating this path is difficult without insider knowledge and there is little transparency among training organizations. I use data science skills to provide insights into the long-term outcomes of ballet dancers in the US. I created Data Pointes around the analysis of multiple datasets I maintain and am looking into ways to expand the organization’s operations as a data-centric business.

I work with two non-profit organizations that are interested in disparities in American ballet. Dance Data Project focuses on the underpromotion of women to leadership, lack of protective policies, and wage disparities in these ballet companies. Gold Standard Arts Foundation is aiming to understand the Asian American and Pacific Islander (AAPI) ballet pipeline and launched the Final Bow for Yellowface initiative which helped modernize depictions of Asian cultures onstage.
