<p>I joined the <a href="https://www.whoi.edu/" target=blank>Woods Hole Oceanographic Institution</a> in fall 2024. Before that, I was an NSF NCAR Postdoctoral Fellow in the ASP program jointly between Computational and
Information Systems Lab (<a href="https://www2.cisl.ucar.edu/" target=blank>CISL</a>) and (<a href="https://www.cgd.ucar.edu/" target=blank>CGD</a>) section and a Postdoctoral Research Associate in the Department for Earth, Environmental and Planetary Sciences (DEEPS) at Brown Univeristy with <a href="http://fox-kemper.com/" target=blank>Baylor Fox-Kemper</a> and <a href="http://www.chrv.at" target=blank>Chris Horvat</a>.</p>
<!-- the Climate & Global Dynamics -->
<p>I graduated from <a href="https://scripps.ucsd.edu" target=blank>Scripps Institution of Oceanography (SIO)</a> in November 2020 in Physical Oceanography with my advisors <a href="http://meteora.ucsd.edu/miller/" target=blank >Arthur "Art" Miller</a>, <a href="http://pordlabs.ucsd.edu/sgille/" target=blank>Sarah Gille</a>, and <a href="https://bcornuelle.scrippsprofiles.ucsd.edu/" target=blank>Bruce Cornuelle</a>, and short postdoc with <a href="https://nicklutsko.github.io" target=blank >Nick Lutsko</a>. Prior to that I studied at GEOMAR in Kiel (2009-2012) and ETH Zurich (2013-2015) Atmosphere, Ocean, and Climate working with Tapio Schneider, Noel Keenlyside and Mojib Latif.</p>
<p>My research focuses on processes that are related to large biases in climate models and the predictability of
mid-latitude weather. My topics span from ocean surface waves to large-scale Rossby waves and the atmospheric general
circulation. I currently focus on:</p>
<h5>• Stochastic air-sea fluxes</h5>
<h5>• Open-ocean surface wave modeling</h5>
<h5>• Sea ice-wave coupling</h5>
<h5>• Ocean remote sensing observations</h5>
<h5>• Atmospheric dynamics and weather extremes</h5><p>

<h2>Particle-in-CelL for Efficient Swell - PiCLES</h2>

<h2>Surface waves govern air-sea exchange</h2>
<p>The sea state controls momentum transfer across the air-sea boundary and alters the surface stress, fluxes of CO2, and heat between the atmosphere and the ocean. I focus on how synoptic-scale variability influences Air-Sea exchange through waves or upper ocean turbulence. I combine simple models of surface wave generation with optimization methods to apply them to ensembles of wave observations.</p>

<h2>Swell generation under extra-tropical storms</h2>
<p>Storms generate swell events that many like to surf. I study how the dynamics of the storm determine the generated swell. For that, I use idealized models, observations from wave buoys and remote sensing data, and non-linear optimization methods to understand the process of wave generation on the synoptic scale.</p>
The key mechanism that leads to the generation of major swell events is trapping wave energy under the moving storm (figure on the left). To understand this, one has to think of wave energy propagation in the reference system of the moving storm. While the wave energy of a short wave travels slower and will be left behind, the wave energy of longer waves will keep up with the moving storm and be further enhanced.<br>
This mechanism compresses the wave energy to a small area, appearing as a small, localized swell source in the open ocean. Stronger storms that move faster will generate larger swell events, while storms that propagate too fast are less efficient in creating strong swell events.<br>

<h2>Surface Winds</h2>
always play a role for air-sea coupling. Surface winds force the ocean on synoptic scales, but they are also in
constant
feedback with the ocean. Surface temperature pattern can change the local winds, and current can change waves.
Surface
winds have to be seen as one aspect of the coupled air-sea boundary layer.
In my research I focus on statistical representation of surface winds over the ocean. Remote sensing product,
reanalysis
data, and state-of-the-art high resolution models allow us to derive wind statistics that vary in space and
time. A
closer lock to these wind statistics show that their shape, i.e. the shape of their PDFs, is not gaussian and
can be
expressed as the superposition of empirical modes.

<h2>Leading modes of surface winds are driven by annular mode variability</h2>
<p>
The leading modes of the surface wind PDF are connected to large-scale drivers of in the atmosphere. For example, the statistics of winds in the mid-latitudes are driven by the momentum balance of the atmospheric column aloft. This provides new insight in how and where surface wind statistics and subsequent air-sea fluxes may change under global warming, as the global warming signal starts to emerge in the large-scale flow. That means we can use the leading mode of the scatterometer wind distribution (upper right panels) to infer the phase of the Annular Mode (black and blue line on the bottom).

<h2>Waves in Sea Ice</h2>
We start to observe waves in sea ice. Waves can break up, disperse, or drift sea ice and alter air-sea heat fluxes within the sea ice. They play a major role in globally retreating sea ice, but the interaction needs to be better understood. In my work, I use satellite and in situ observations to better understand how waves surface waves behave in sea ice.
Waves in the Marginal Ice Zone (MIZ) are a dominant source for the mechanical breaking of sea ice with potentially enormous consequences for the air-sea exchange in the MIZ. I study the impact of waves on sea ice through remote sensing and idealized models to better represent these processes in climate models.
