Different approaches are used for downscaling, including regionalization and Convolutional Neural Network (CNN) pattern reconstruction.

2019 – 2022 Multi-scale Prediction of Flash Drought in the United States
Department of Earth and Planetary Sciences (EPS), Johns Hopkins University (JHU), Baltimore, Maryland, USA
PREEVENTS Track 2: Collaborative Research: Flash droughts: process, prediction, and the central role of vegetation in their evolution is a 3-year project to advance efforts to understand and forecast flash droughts (FD) by targeting three characteristic features: (1) land surface memory is a key component of FD, (2) evaporative demand is a leading driver of FD onset, (3) vegetation plays a central role in FD development through its influence on soil moisture and turbulent heat fluxes. Deep Learning algorithms are used for the prediction and classification of flash droughts.

2017 – 2020 Applications of Deep Learning to S2S Prediction & Downscaling
Department of Earth and Planetary Sciences (EPS), Johns Hopkins University (JHU), Baltimore, Maryland, USA
Convolutional Neural Networks (CNN) are implemented and optimized with a custom loss function (based on objective climate regionalization) to improve dynamical forecasts at subseasonal to seasonal (S2S) timescales. Training is performed using historical observations and the North American Multi-Model Ensemble (NMME) monthly forecasts.

2017 – 2020 Environmental Determinants of Enteric Infectious Disease
Department of Earth and Planetary Sciences (EPS), Johns Hopkins University (JHU), Baltimore, Maryland, USA
Determinants of Enteric Infectious Disease: a GEO Platform for Analysis and Risk Assessment is a 3-year project to develop an environmentally informed risk monitoring and early warning application that will inform decision makers for appropriate interventions and investments needed to reduce enteric infectious (EID) diseases. The project will leverage data from the MAL-ED project funding by the Bill and Melinda Gates Foundation and bridge this health information with environmental data from earth observations. Very comprehensive model development to include a wide range of predictor variables as well as targeting 8 countries within the MAL-ED sites, generating a global picture of EID.

2017 – 2018 Advanced Seminar in Remote Sensing
Department of Earth and Planetary Sciences (EPS), Johns Hopkins University (JHU), Baltimore, Maryland, USA
The fall 2017 iteration of Advanced Seminar in Remote Sensing focused on the application, interpretation, and visualization of Land Data Assimilation Systems (LDAS). Through lectures, exercises, and a semester project, students learnt the theory behind LDAS, run LDAS simulations using the NASA Land Information System (LIS), and built web visualization applications for LDAS output using the open-source Tethys scientific visualization platform.

2016 – 2018 The NASA Land Information System (LIS)
