3. Zeno
Collaborated with local design firm on next
generation of acne treatment device.
Worked closely with industrial designer to
create physical prototype with functioning
user interface.
Planned, created, and conducted customer
interviews and usability testing.
Provided feedback and recommendations
for hardware and software design to
improve the ease of use of the device.

4. NeuroVista
Consulted for a local company
developing an implantable
epilepsy device.
Conducted heuristic evaluation of
wearable device including
hardware and software.
Planned, created, and conducted
usability evaluation of device and
provided recommendations for
improving usability and
ergonomics of device.

5. Stent Graft
Consulted with local design
group to redesign an aortic
stent graft in a compressed
schedule.
Added new features but
improved ease of use by
considering the
user, workflow, and
ergonomic guidelines.

6. Northstar Programmer
The programmer used for Northstar’s clinical trials
was confusing and error-ridden. Each user needed
a significant amount of training to successfully
operate the programmer and the number of
complaints reported to Northstar was
unacceptable.
I redesigned the programmer using a user centered
process and significantly improved the user
experience, decreased complaints to the
company, and eliminated the need for individual
training.

10. Tegic Communications
Planned, created, and
executed extensive
benchmark test. Results
were used by
marketing, sales, and
development.
Created specification for
ideal T9 implementation to
be used as a guideline for
future development efforts.

11. SonoSiteiLook
The iLook was a completely new concept for SonoSite.
Previous products were hand carried but iLook was
designed to be handheld. Additionally, iLook was
designed for non-traditional users with little to no
ultrasound experience. I conducted extensive user
research to identify user needs and requirements. These
needs and requirements were used to drive the design.
A thorough ergonomic evaluation was completed and
extensive usability testing was conducted to optimize
comfort during use. I worked closely with industrial
design and mechanical engineering to create a form
factor that was comfortable for all users.

12. Evolution of iLook Form Factor

13. SonoSiteiLook User Interface
While working on the form factor, I was also developing
the user interface. I conduced several tests to
determined the input method, created the screen
layout, determined the interaction model, and created
low-fidelity prototypes.
Early integration of the
hardware and software was
prototyped by using a wood
model with a flip-chart user
interface. This was evaluated
during usability testing.

14. iLook Final Design

15. FiatLux Imaging
Conducted user research
to establish user
requirements for next
generation product.
Created design standard to
ensure consistency across
designs.
Conducted heuristic
evaluation of existing
software to identify
strengths and weaknesses.
