About

Hi.

I’m Rohit Goswami, better known across the web as HaoZeke. I’m not the first of my name, which is why instead of rgoswami, I occasionally use rg0swami when I need to be identified by something closer to my name.

The actual username is a throwback to back when people liked being anonymous (and with multiple personalities) online, so that ought to give an idea of how old I am. A curriculum vitae is available here.

It is difficult to keep this section short and not let it spill into an unstructured memoir. For a while I considered trying to consolidate my online presences but that turned out to be completely impossible without a series of posts and avatars¹. I did however eventually set up a sporadically updated collection of web-links involving me. There is also, a separate list of quotes, or other things I have something to say about.

Tangible Positions

• From May 2025, I am now associated with labCOSMO at the École Polytechnique Fédérale de Lausanne (EPFL), working closly with Dr. Guillaume Fraux and Prof. Michele Ceriotti

Intangible Positions

This is a set of things which are primarily online and/or voluntary in a non-academic sense.

• I maintain within NumPy, mostly parts of f2py
• I serve on the board of the Nordic Research Software Engineers association
• I administer and design a bunch of websites, mostly verified on Keybase
• I am a certified Software Carpentries instructor
• I officially maintain, for the Software Carpentries, the lesson on R (r-novice-inflammation)
• I also maintain some packages on the AUR (ArchLinux User Repository)
• I maintain(ed) the official LineageOS image for the Xperia Z5 Dual

Historical Connections

What follows is a more informal set of places I am or have been associated with or are of significance to me². Many of these are tangible, but better ordered in this manner.

Kingston

• I spent four months in 2025 officially with the lab of Prof. Laurent Béland at Queen’s University
  • As a work permit exempt TEER-1 research visitor

Reykjavík

• I am associated with the reputed Jonsson group of the Science Institute at the University of Iceland, where I benefit from the guidance of the erudite and inspiring Prof. Hannes Jonsson
  • From January 2021 to 2025, I held a three year doctoral fellowship from the Icelandic Research Fund (Rannís) for my project on “Magnetic interactions of itinerant electrons modeled using Bayesian machine learning” tenable at the Science Institute with Prof. Hannes Jónsson as my supervisor and Prof. Birgir Hrafnkelsson as my co-supervisor
• My doctoral committee is here, which includes the very excellent inputs of Dr. Elvar Jonsson
• From August 2021 to June 2025, I was with Quansight Labs as a Software Engineer (I–>II) and reported to (Dr. Ralf Gommers –> Dr. Melissa Weber Mendonça)
  • My work initially revolved around f2py through the CZI NumPy project with Dr. Melissa Weber Mendonça and Dr. Pearu Peterson
  • Passed through working on PyTorch and writing meson bindings to OpenBLAS
  • Picked up maintaining ASV (in addition to F2PY)
• I collaborated closely with the brilliant Dr. Ondřej Čertík over the course of both on my GSoD 2020 long project for SymEngine and over GSoC 2021 on the LFortran compiler
• I was a Fellow at the Institute for Pure and Applied Mathematics (IPAM) for its Spring 2021 program on “Tensor Methods and Emerging Applications to the Physical and Data Sciences”
• I have also benefited from sitting in on some formal coursework here, which was a fascinatingly useful experience

Kanpur

• I retain a close association with the fantastic Femtolab at IIT Kanpur under Prof. Debabrata Goswami, who has provided constant guidance throughout my career
• I am the co-lead developer of the FOSS scientific d-SEAMS software suite for graph theoretic approaches to structure determination of molecular dynamics simulations, along with my exceptional co-lead Amrita Goswami of the CNS Lab under Prof. Jayant K. Singh at IITK
• I worked with the Nair group as part of the Summer Undergraduate in Research Excellence (SURGE) program, also at IITK
• Harcourt Butler Technical Institute (HBTI) Kanpur, or the Harcourt Butler Technological University, as it is now called, was where I trained to be a chemical engineer
• I honed coursework development and teaching with univ.ai

Bombay

• I spent a formative summer under Prof. Rajarshi Chakrabarti of the IIT Bombay Chemistry department, who has been instrumental in developing my interests
• I also spent some time discussing experiments with Prof. Rajdip Bandyopadhyaya of the IIT Bombay Chemical Engineering department during an industrial internship in fragnance compounding at the R&D department of KEVA Ltd. under Dr. Debojit Chakrabarty

Bangalore

• At IISc, I had the good fortune to meet Prof. Hannes Jonsson at a summer workshop on Rare events
• At the BIC, I undertook formal machine learning and artificial intelligence training under Harvard’s Dr. Rahul Dave and Dr. Pavlos Protopapas as part of the univ.ai summer course

Chennai

• I spent a very fruitful summer on quantum tomography under Prof. Sibashish Ghosh at the Institute for Mathematical Sciences (IMSc Chennai)

Avatars

I thought it might be of use to list a few of my more official visages. This is mostly to ensure people do not confuse me with a Sasquatch³. These mugshots are exactly that, mugshots for profile icons⁴.
