Places I’ve worked

Big Apple Data Science is a consultancy that Luke and I run as a side project. We do machine learning, predictive modeling, and solve statistical problems for a variety of scientific and industrial clients. The best part is that we get to prioritize working on interesting problems.

Integral Ad Science is a data company in the west village, where I’m currently a data scientist. We build models and work with Python, Hadoop, Infobright, R, SQL, and Luigi. It’s a great job and I’m very happy there; I have no plans to leave in the foreseeable future.

Collective Media is an ad tech company in midtown where I was a data scientist. We worked on middling-to-large modeling problems with R, Python, various Unix-flavored tools, SQL, and the Hadoop ecosystem. We also had Netezzas, which are really interesting special-purpose machines.

Columbia University Energy and Tribology Lab: At Columbia, I spent a few years as a researcher for Professor Elon Terrell. Our toolchain was Linux, Python, Mathematica, Abaqus, and LaTeX. We did projects mostly related to the friction, wear and lubrication of carbon nanocomposites. I worked on several projects, including the design and construction of an instrumented friction testing machine, programming CNC mills to make most of the parts, and writing the control software in Labview. Later I started the development of a new graphene-doped nanocomposite material.

Tyco Electronics is a hardware company in Middletown, Pennsylvania that makes electrical signaling and power transfer connectors. I spent summer 2012 in their R&D department on a project hunting for parts failures. I was applying HALT/HASS reliability methods to early detection of latent manufacturing defects in high-bandwidth industrial signalling connectors. This is a really cool project and you should read more it about on the Projects page.

Traylor Brothers Heavy Civil Engineering, Underground Division: I spent the summer of 2011 as an undergraduate Project Management intern on the East Side Access LIRR expansion project in New York City. We were operating a pair of 22 foot diameter TBM’s, which are really cool machines, and boring tunnels from Long Island to Grand Central Station. I managed a topside support construction project and wrote a few chunks of software in Visual Basic (ugh, never again) that automated inventory management and data entry for our spare machine parts (of which there were lots – like 50,000 SKU’s). The software is closed-source and owned by Traylor.

Argonne National Laboratory: I spent two consecutive summers working at ANL in Chicago. My projects were related to the development of improved materials and coatings for improving transportation efficiency. A few summers ago, I worked for what was at that time a young startup called It’s now one of the dominant web printshops, a fact which I attribute solely to my efforts hacking on my badly-composed Javascript for their marketing department. I also spent about half my time doing non-technical marketing stuff.

Montana Democratic Party: During 2008 and 2009, I was the IT department for the Montana Democratic Party. When I started they had a (mostly broken) static HTML site and nearly-nonexistent email marketing. I deployed a Drupal site (which is still up as of this writing. Check it out!), revamped their email marketing, and solved many, many helpdesk problems. I also did some of their graphic design, mostly for print.

Carroll College IT Department: I spent a few years in the Helpdesk trenches at a small school in Montana called Carroll College. Student and faculty support calls, network hardware deployment, and web programming.
