# research

I study quantum information, currently trying to extend this paper.

In the past, I’ve thought about quantum state estimation, philosophy of science, computational fluids, and lattice spin systems.

# teaching

I frequently teach programming to academics with the non-profit Software Carpentry.

They recently renamed to The Carpentries. It is one of my favorite organizations.

At CarpentryConnect Davis in 2018, I blogged about different ways people find this group.

at UC Berkeley (blog post)

at Purdue University

at SSAI / NASA-Langley (blog post)
at West Virginia University
at University of Arkansas
at SSAI / NASA-Wise (blog post)
at Elizabeth City State University

at Stony Brook University
at UC San Francisco
at UC Berkeley
at University of Virgin Islands (blog post)
at UC San Francisco

at Georgia Tech
at National Academy of Sciences (with Data Carpentry)
at Lawrence Berkeley National Lab / US-ATLAS
at SSAI / NASA-JPL (with Data Carpentry)
at TribalDATA / Bishop Paiute Tribe (with Data Carpentry)

at SSAI / NASA-JPL (with Data Carpentry)

I also assist with “Software Carpentry”-inspired workshops. In 2015-16, I helped teach a Python Boot Camp at LBNL and organized weekly “Learn to Code” meetups at my co-op.

Expect the best possible human from me, but give me grace when I fall short. I might prove you right more often than wrong.
