I deliver User Research, Usability and UX processes. I focus mainly on design optimization, and base my development on User-Centric & ethnographic methods.

I like to inspire stakeholders and engage them into the core values of the design process through dynamic workshops.

My Name is Lucas, and I am a Usability and User Researcher.

This is me, Lucas Wxyz. People also know me as Lucas Em.


Every User Researcher has their own toolbox. One that takes shape through the years. Each element added by curiosity or public demand.

Trial-Error and personal preferences helped me acquire the tools I have to offer clients, based on each particular situation.

I want you to take a look at my very one Usability and User Research Toolbox.

Some of them are obvious choices, like Usability Testing; Others are a little more innovative, like Visual Anthropology. Others are more academic, such as Ethnographic Interviews; and others are there to explore many possibilities, like Prototyping.

I am really interested in the development of Personas and the multiple applications they have all around the Design Process.

So come on in, take a look at what I have to offer and let me know how I can help you make the world of your users (and design team) a better one – one project at the time!


I like to DO things. I like to TEACH things. I don’t agree with Woody Allen when he says that “Those who can’t do, teach. Those who can’t teach, teach gym”. I like to do things while teaching.
I have designed and developed a series of workshops for the different stages of the design process based on design thinking and participatory design.
Most of the workshops are focused on those that need to develop a product: Designers, Developers, Project Managers.
My goal with each of the workshops is that participants can go back to their desks, their white boards and create better products that are connected with their users’ needs.



For the last few years I have worked as a freelance and in-house consultant for different clients.

As a consultant I was only a part of the project for a short period. Sometimes my participation was longer than normal, but in average my participation was for about 3 weeks.

Many of those projects were done under Non-Disclosure Agreements, so while I can’t talk about the products or the results, I want to showcase here a short reference of the methods that were used on each one of them.
