Education

2020-present PhD Mathematics and Atmosphere Ocean Science, Center for Atmosphere Ocean Science, Courant Institute of Mathematical Sciences, New York University,

Supported by National Science Foundation’s Graduate Research Fellowship and NYU’s MacCracken fellowship.

2016 - 2020 BS Geophysical Sciences, Mathematics, the University of Chicago with special honors

Publications

  • What controls the probability distribution of local wave activity in the midlatitudes? C. Valva, N. Nakamura; 2021; JGR Atmospheres (in press)

Research and Workshops

  • Workshop on Dynamics and Data in the COVID-19 Pandemic (virtually) at the American Institute of Mathematics Summer 2020

    A multiscale approach to modeling university impact on municipal COVID-19 dynamics: Explored the use of multiscale modeling and data assimilation improved computing performance and accuracy with sample case of disease dynamics. (Organized by the Mathematical Climate Research Network.)

  • College Research Fellow at the University of Chicago:

    Advisor: Noboru Nakamura, professor of geophysical sciences, 2018-2020  

    Distributions of Midlatitude Local Finite-Amplitude Wave Activity: Explored the controls on probability distributions of local wave activity through simple models and nonlinear PDEs. Study relation between extreme local wave activity values and weather including geopotential height and temperature.

    Extreme events as wave construction: Explored weather extremes through the decomposition of geopotential height into stationary and transient components, applying spectral analysis to the latter. Examined robustness of the reconstructed distribution from these spectra and its sensitivity to various wave components.  

  • Mathematics REU at the University of Chicago Summer 2019

    Riemannian Geometry and Ergodic Flow on Surfaces of Negative Curvature: Studied the properties of geodesic flow on spaces with negative curvature which include ergodicity and mixing. Also obtained a background in Riemannian geometry, covariant derivatives, and curvature.

  • Jeff Metcalf Summer Undergraduate Research Scholar at the Ecosystems Center, Marine Biological Laboratory

    Advisor: Ivan Valiela, distinguished scientist, Summer 2017, 2018  

    Regime shifts of nitrogen loads and estuarine response: Analyzed changed trajectories of nitrogen loads in cape cod estuaries and identified drivers of change over 20 years of data. Explored estuarine water quality and biological response to this regime shift as well as varying levels of nitrogen loading. Work included sampling in several Cape Cod estuaries.

Skills

Fluent in Julia, Python, Javascript, MATLAB R, and LaTeX with experience in HTML, Jekyll, Markdown, C++, and Fortran.
