Climate change scientist and crop modeler. Studying food security and global sustainability at @NASA, @Columbia, and @PIK_Climate.
New York, NY
Joined September 2018
I am looking for a Postdoc to join my team at the @Columbia Climate School and @NASA GISS. We will be working with @corteva and advance our understanding of historical and future crop breeding using crop models. Exciting and ambitious, please share! https://t.co/izSv1hI3MW

In a super interesting new paper we show how ENSO and other climate oscillations influence crop yield variability today and in the future. Check it out! https://t.co/oGlGNWbU7b

The Geography Department at Humboldt University Berlin is opening a new tenure-track position "Geography of Global Environmental Change". A great department, that's where I graduated. And Berlin is obviously awesome! https://t.co/O3LBDNYQO6

“Price spikes are like seismographs for the food system, registering much larger drama elsewhere — and sometimes suggesting more tectonic changes underway as well,” @dwallacewells writes. Read:

Fantastic New York Times piece by @dwallacewells about the future of our food system is out today! Great overview of many non-trivial challenges and they use our crop modeling data to visualize future climatic pressures on ag productivity. Good job! https://t.co/clUldOeIdz

Uncertainties in climate impact assessments are still crazy high – largely attributed to impact models, not climate models. In our new paper we quantify uncertainty sources and highlight the systematic funding gap between climate and impact communities https://t.co/shW8xNdsdb

A new paper uses our crop modeling data to highlight the threat of future flooding for global agriculture. Interesting read! But flooding is also an important blindspot of the crop models, something we are trying to address in a new project. I'm hiring!

Solar Radiation Management is getting real but we don't understand the complex feedbacks it may cause, affecting food production, human health, monsoon seasons and more. I just spoke to NPR about it:
npr.org
In a parking lot and on San Francisco Bay, NPR witnesses two different tests for solar geoengineering to tackle climate change. With much science unsettled, experts say regulations aren't keeping up.

Abstract. Elevated surface ozone (O3) concentrations can negatively impact growth and development of crop production by reducing photosynthesis and accelerating leaf senescence. Under unabated...

Published just in time for the #WorldFoodDay on Monday, check out our new commentary on future nutritional requirements led by Bianca Carducci!
A just, nutritious, sustainable food system requires a paradigm shift on where, what, and how we grow food + equitable distribution channels, say @columbiaclimate's Bianca Carducci, @JonasJaegermeyr, Jessica Fanzo, @NASAGISS's @AlexRuane. Via @OneEarth_CP.
