Ansiblify everything, I say! With Ansible roles and playbooks I can express configuration as code (CaC) and even infrastructure as code (IaC) while easily managing a single server or whole fleets of containers and virtual machines. Some highlights from more than a hundred publicly shared roles:

• dotfiles

• R

• LXD

• python3

• i3wm

• wallabag

• tailscale

• codium

• firefox-sync

• gitea

• TeXLive

• jupyter

• nextcloud

• Pi-hole

• RSS

• Python

• Postfix

• Dovecot

These slides are quite outdated by now, but they help to demonstrate my long-standing conviction on the importance of open scientific practices.

Multiscale Modelling of Materials and Molecules (MMMM) conference organized by eSSENCE, a Swedish national strategic research program in e-science.

Lightning talk presenting the latest developments in my R package periodicdata at the second Nordic Research Software Engineers conference.

A one-day conference on tech, internet, integrity and decentralization organized by the Swedish chapter of the Internet Society, SNUS, DFRI and dataskydd.net.

Gave a short presentation of my Ansible playbook for the academic desktop at the first in-person conference of the Nordic Research Software Engineers.

A one-day conference on tech, internet, integrity and decentralization.

Hands-on workshop with lots of examples demonstrating uses of awk, led by Dr Pavlin Mitev from UPPMAX.

An entirely online conference, a first for yours truly. I adapted to it by creating this animated plot as the centre-piece to my poster.

Presented the near-complete mineralization of methylene blue on low-dimensional zinc oxide quantum dot suspensions.

Presented results from my on-going research on the opto-electronic properties of semiconductor colloidal suspensions. This conference was organized by Uppsala University's two chemistry departments.

I was invited to give a LaTeX workshop for fellow PhD students.

Presented a talk of my early research into ALD-coating of electrodeposited zinc oxide nanorods and their photocatalytic and photoelectrochemical properties.

Shared some of my work into CBD-coated zinc oxide nanorods and their photocatalytic and photoelectrochemical properties at the Materials Research Society spring meeting in San Francisco.

Presented results from my early research into coating different visible-light absorbing semiconductors on top of nanostructured zinc oxide at the 19th International conference on photochemical conversion and storage of solar energy.

Supervised a masters-level student for a 15 hp course (half a semester) in materials science entailing laboratory synthesis and characterization on work closely related to my own research, successfully completed by the student into a written report.

Developed and led (jointly) a four-day course introducing R for postgrads and postdocs at the Ångström Laboratory (around 20 participants).

Teaching assistant in charge of laboratory part of courses in basic chemistry, inorganic chemistry, and physical chemistry (solo or together with other lab TAs, each TA assigned 16 students).

Base guardsman and "skyddsvakt".

Exam invigilator in charge of a class of no more than 30 candidates during the Swedish Scholastic Aptitude Test organized by the Swedish Council for Higher Education ("universitets- och högskolerådet").

Appointed as the doctoral student representative by the Swedish National Union of Students (SFS) to the Swedish Higher Education Authority's assessment panel for conferring doctoral degree-awarding powers to Dalarna University College in the subject of "resurseffektiv byggd miljö" (resource-efficient built environment).

This was great fun - helping adults accomplish something they thought near-impossible. Of course, the participants already did the hard part by signing up to the course, and the instructors benefitted from excellent manuals and help provided by the project.

Assistant invigilator for a class of around 90 candidates during the Swedish Scholastic Aptitude Test organized by the Swedish Council for Higher Education ("universitets- och högskolerådet"), aided by two other assistants and an exam invigilator.

In this capacity I represented the doctoral student collective at the university in several matters, such as the university's process to develop its research strategy (2013–2014) and its work to create a unified English-language research education web portal (2013). I led or contributed to the doctoral board's internal work such as penning opinion pieces and drafting annual plans, appointing trustees, and conducting meetings with university officials.

The Quality board, chaired by the deputy vice-chancellor, concerned itself with questions such as the Quality in Research Assessment, global university rankings (i.e., discussing their benefits or harms), academic integrity, responding to national assessment panels, and many other issues.
