A small, independent research group studying how software actually
gets made — and how it feels to make it.
Our mission
We want to understand the lived experience — the qualia — of
software work. The texture of a good morning at the keyboard, the
slow build-up of trust on a new team, the quiet moment when a
developer realizes they're stuck. The things that don't show up in
metrics but shape every line of code that gets written.
Our approach
We use qualitative methods — interviews, observation, careful
interpretation — and lean on grounded theory to let patterns emerge
from what people actually tell us, rather than testing hypotheses
we brought in from outside. Most of our studies start with a long
conversation and end with a great deal of re-reading and
re-thinking.
We are not trying to produce dashboards or benchmarks. The
questions we care about don't have numerical answers; they have
careful, considered ones.
Who we are
Dr. Sarah Köksal
Principal Researcher
Sarah is a qualitative researcher trained in cultural
anthropology and intercultural communication. Her PhD at LMU
Munich examined the lives of Chinese international students in
the United States — work that took her to UC Berkeley as a
visiting PhD student and gave her years of practice in the kind
of patient, immersive interviewing LESE Lab is built around.
She currently works as a Senior UX Researcher at HERO Software,
where she studies how people actually use the tools built for
them. Before HERO she was a postdoctoral researcher at TU
München. Earlier still, she conducted fieldwork on the German
expatriate community in Mongolia at the National University of
Mongolia.

Research interests
Qualitative research methods. Identity, belonging, and how people
make sense of unfamiliar environments — themes from her earlier
fieldwork that translate naturally to studying software work as
a culture and a craft.
Leif spent his PhD at Leibniz Universität Hannover studying how
software engineers adopt new practices, and how small,
carefully-designed nudges can shift habits without nagging. His
thesis was titled Improving the Adoption of Software
Engineering Practices Through Persuasive Interventions. He
then spent a year at the University of Victoria as a
postdoctoral research fellow, working on collaboration tools for
developers and running studies — including one on how developers
use Twitter.
After his postdoc he moved into industry. He has been building
for the web since 1996, working remotely since 2014, and is
currently a Senior Engineering Manager at Ghost, where he leads
a distributed engineering team. The questions that drew him into
research never quite left him. LESE Lab is the way he keeps
asking them.

Research interests
Developer collaboration and tooling, remote and asynchronous
engineering practice, persuasive design, how engineering cultures
form and change over time.
LESE Lab is small on purpose. Most of our work happens in long
conversations — about transcripts, about half-formed ideas, about
what we're still missing. We treat interpretation as a craft and a
shared activity, and we're suspicious of any process that pretends
qualitative research can be done quickly.
We are an independent, non-accredited research group. We are not
affiliated with any university, and we do not seek to be one. That
independence lets us pursue questions on their own merits and at
their own pace.
