A picture of me

Chris Geoga

I am a statistician and applied mathematician with broad interests in statistical methodology and computing in the physical sciences. My primary interest is modeling complicated dependence structure in real-life temporal/spatial/spatio-temporal processes, and I'm particularly interested in theoretical questions that are motivated by computationally scalable methods and approximations. I have specific experience in the fields of maximum likelihood estimation for Gaussian processes, nonparametric spectral density estimation in one and several dimensions, nonstationary spatio-temporal modeling of micrometeorological processes, and some applications of signal processing and multiple testing strategies to the analysis of power systems.

I am currently a PhD student in the Department of Statistics at Rutgers University working with Michael Stein. Since August 2016, I have worked at Argonne National Laboratory under the supervision of Mihai Anitescu.


Applied Math:



I write all software using the GPLv2 license. If that's a deal breaker for you, probably not much point to reading this section.


A short and incomplete list.


I do not use any social media or internet networking websites. If you see any account with my name on it, please assume that it is not really me. Please contact me by email at one of these addresses:

I also use XMPP, so if you'd prefer to communicate by instant messaging please first reach out by email and I will share that contact information with you.
