Hi! I'm Jocelyn, a sophomore at MIT pursuing a major in Electrical Engineering and Computer Science alongisde a minor in Economics. I'm passionate about technology, behavioral science, and AI policy and ethics. The driving questions behind my research and my projects are: how can we quantify behavioral characteristics such as emotion and creativity, how can we connect people, and how can we provide equitable technology? In the past, I've worked at Citadel LLC (Software Engineering Intern), Facebook (Software Engineering Intern), and Affectiva (Data Science Intern). I hope to use my knowledge in CS and machine learning to better understand human behavior and contribute to causes related to mental disability, education, and assistive technology, as well as drive research behind policy decisions regarding artificial intelligence. Aside from my work, I'm a Chinese American author and digital artist based in Los Angeles.
Evolutionary Convergence in Vascular Branching
Branching in vascular networks and in overall organismic form is one of the most common and ancient features of multicellular plants, fungi and animals. These networks deliver resources and eliminate wastes from early development onward, and even play a vital role in the growth, prognosis, and treatment of tumors and stroke recovery. Because of these basic and applied reasons there is immense interest in identifying key features of vascular branching and their connection to biological function. Here we classify diverse branching networks-mouse lung, human head and torso, angiosperm plants, and gymnosperm plants-by harnessing recent advances in medical imaging, algorithms and software for extracting vascular data, theory for resource-distribution networks, and machine-learning. Specifically, we apply standard machine-learning techniques to a variety of feature spaces. Our results show that our theoretically-informed feature spaces-especially those that determine blood flow rate-combined with Kernel Density Estimation are best at distinguishing networks. Our categorization of networks enhances the mapping between biologic function-such as the dependence of metabolic rate on body mass-to vascular branching traits among organisms and organs. We accomplish this by analyzing how variation in metabolic scaling exponents-around the canonical value of 3/4-arises despite differences in vascular traits. Our results reveal how network categorization and variation in metabolic scaling are both heavily determined by scaling ratios of vessel radii-changes and asymmetries across branching generations-that strongly constrain rates of fluid flow. These linkages will improve understanding of evolutionary convergence across plants and animals while also potentially aiding prognosis and treatment of vascular pathologies and other diseased states.Source code available herePaper available here

Juneau is a mess. From the outside, she has it all together: she is smart, warm, and well-liked. But behind closed doors, she lets all the pent-up emotions flood out. Haiden is her best friend. He’s her rock, but he’s also absolutely off-limits. Caught in the midst of turbulence back home and at school, Juneau struggles to uncover her own identity as the voices around her are so disharmonious. The only thing that helps her drown out the noise is Haiden. There’s just one problem: he’s moving to the other side of the world in three months.
But with a heart full of hope, she wonders if perhaps their love can perservere across every time zone.
