SEES 2021 Nandini R -On Being a SEES Earth System Explorer

SEES2021 Earth System Explorer

Coming into the NASA SEES Internship, I had only ever experienced science through a
one-dimensional lens. I always knew the results, experimenting just to prove existing
knowledge. This internship taught me to look outside the box and challenge my preconceived
notions to discover new relationships that exist on our earth.

Through our weekly meetings, I got to interact with guest speakers and my mentors who were
taking on various projects in the field of epidemiology. Inspired by one such meeting where Dr.
Chellappan used machine learning to predict the mosquito species in an image, I wanted to
explore the power of this tool. I started asking questions, intrigued by how the model used
mathematical values to make sense of the pixels in the image.

My swarm of questions did not go unnoticed - fellow researcher Sriram Elango picked up on my
interest in AI. He messaged me in the zoom chat and expressed his interest in doing a project
with machine learning as well! We decided to research together, brainstorming ideas for our

We realized to prevent the spread of mosquito-borne diseases, we had to focus on the root of
the problem: mosquito breeding grounds. We researched existing habitat detection technology,
noticing the expensive and time-consuming approach to map areas using Drones and
multispectral imaging like Lidar. We knew this process had to be streamlined and applied to a
macro-scale, so we built an autonomous mosquito habitat detector. We annotated hundreds of
satellite images and inputted them into a convolutional neural network, classifying the habitats
as rivers, ponds, and inlets. Given any satellite image, the model is able to clearly identify
mosquito habitats with astounding accuracy, potentially allowing for a cheap and accessible
solution to mosquito habitat detection that can be integrated into public health policies.

We have finished our research paper outlining our process of data collection and presenting our
model as a proof of concept. We are currently working on publishing our paper with the help of
our amazing mentors and hope to share our findings with the scientific community. The NASA
SEES Internship has taught me to explore and experiment without constraint. I have come to
appreciate the game-changing work that NASA has done and hope to become a part of that
change as I grow into a scientist in the future.
