Hello! I am a physical oceanographer who uses observational data to study surface ocean processes.
- I am currently a PhD candidate at Columbia University, working at the Lamont-Doherty Earth Observatory with Dr. Christopher Zappa
- I am funded by a NASA FINESST grant to characterize high salinity shelf water1 formation in the Terra Nova Bay polynya2 in the Ross Sea of Antarctica
- I am also working to evaluate the applicability of Monin-Obukhov similarity theory3 in parameterizing turbulence kinetic energy dissipation rates4 in the surface ocean boundary layer
1 A major component of Antarctic Bottom Water, a water mass that fills the lowest kilometer of the world’s oceans and is important to our understanding of past and future climate!
2 An opening in the sea ice created by strong winds or the upwelling of warm water. Typically 100-1000 square kilometers in size
3 A methodology for deriving "semi-empirical" formulas based on dimensional analysis
4 A way to quantify turbulence, the chaotic, swirling motions that mix gasses, nutrients, heat, and other important things between and within the ocean and atmosphere

Outside of research...
I really enjoy outreach work, especially when it involves showing young people that scientific research and coding is not just for "geniuses" or solemn-faced men clad in white lab coats! Some things I've been involved in are Girls Who Code @ Columbia University , LDEO Open House and Girls' Science Day at Columbia . I am currently part of pyclub , an effort to introduce local high school students to coding in python through oceanography.
For Open House 2020, I made a fun video about oceanographic research cruises using media that my friends and I have collected while out at sea.
In my free time, I like to learn Korean, bike around NYC, and think about adopting a dog.
