Karthik Venkataramani

Welcome to my homepage!

I'm a Postdoctoral Scholar at the University of Washington, working with Dr. David Shean on using deep learning approaches to refine digital elevation models generated from stereo imagery on a global scale, as part of the upcoming Surface Topography and Vegetation mission.

Prior to this, I was a Postdoctoral Fellow at the NASA Jet Propulsion Laboratory, working on using machine learning techniques to understand dynamic surface water extent from harmonized optical and synthetic aperture radar (SAR) data. The work fed into the broader Observation Products from End-Users from Remote Sensing Analysis (OPERA) project, and uses data from LandSat, Sentinel-1/2, and the upcoming NASA-ISRO SAR (NISAR) mission. 

Prior to this, I was a Research Scientist at Orion Space Solutions (formerly known as ASTRA). I completed my Masters and PhD in Electrical and Computer Engineering from Virginia Tech, where I worked at the Center for Space Science and Engineering Research (Space@VT). My graduate research primarily focused on building numerical models of the Earth's upper atmosphere and working with instrumentation to help study space weather phenomena. 

I am currently working on projects involving the ionosphere, positioning algorithms and data visualization tools, along with a healthy dose of machine learning and computer aided design in my spare time. I've been learning how to Git and you can find code samples and projects that I've been playing with in my spare time here.
