INTERVIEW

Dr. José Fernández

Villaseñor

Freescale Semiconductor

How did you get into electrical

engineering and when did

you start?

During high school, I loved all the

science classes such as physics,

math and biology. In my third year

of high school, I chose to focus

on physics and mathematics. The

advanced physics, electronics and

calculus classes were amazing

because they let me use my

imagination and create things.

At the same time, it was almost

like playing with the circuits and

applications.

for an electronics design house

focused on health and automotive

applications. I also worked in a

clinic for Mexico’s Health Ministry

where I provided preventative and

treatment medicine to high-risk,

low-income communities.

renal and liver donors with the

transplantation unit and worked

with the internal medicine and

gastroenterology department at

a non-profit, public hospital in

Guadalajara.

For the last 13 years, I’ve also taught

courses in electronics, medicine

I did research on protocols for

Dr. José Fernández Villaseñor - Medical Product Manager

After that, I decided to pursue a

career in electrical engineering.

Even though I enjoyed electronics, I

always wished there was a medical/

biology group available when I was

in high school.

Can you tell us about your

work experience/history

before becoming the

Medical Product Manager at

and surgery at various universities

in their electronics and biomedical

departments.

both? Why not apply technology to

medicine to fully understand the

needs of both the market and the

user (patient)? This way, we can

offer better solutions and improve

the health of everyone.

What type of work do you do

with this area of study?

Some of the medical and surgical

procedures we do are to correct

or improve these conditions. One

of the things I also focus on is

medical sport supplementation.

With that, my major objective is to

improve an athlete’s performance.

For this we learn how to detect and

correct muscular, neural and joint

imbalance.

What have been some of your

inluences that have helped

you get to where you are

today?

While at the university, I earned

a scholarship to study Japanese

in Kyoto. This experience was a

crossroad in my life. I learned how

to improve my time management

skills, perfect and master my daily

work, and ultimately decide that I

had just enough time and energy to

push myself to the limit and pursue

an additional career. When I was in

my fourth semester of electronics

engineering, I started my first

semester of medical school. The

universities were far apart, and my

days were long—starting at 5:00

a.m. and finishing around 1:00 a.m.

This discipline has continued to

motivate me today as a practicing

surgeon and as an electronics

engineer for Freescale.

Can you tell us more about

aesthetic medicine?

Aesthetic medicine is focused

on improving the human body’s

aesthetics and helping in all “anti-

aging” medical treatments. Reasons

for this could be due to accidents,

and diseases such as vitiligo, acne,

or just because patients do not feel

comfortable with the way they look.

What are your favorite

hardware tools that you use?

I really enjoy using the Freescale

Tower System development board,

which is a designer’s platform to

easily prototype and test home

portable medical equipment. The

best part about it is that you can just

plug in the boards you need, such

as the serial or LCD boards, and

you don’t need a hardware design

at all. You just use them as stackable

boards.

During my first year

at engineering school,

I kept blowing out the

capacitors. Electrolytic

capacitors had a figure

similar to a “1” which

marked the leg that was

supposed to be connected

to the ground. I kept

saying to myself, “This

must mean the digital 1

so it should go directly to

Vcc.” Well, after seven or

eight capacitor explosions,

I found out it didn’t!

What are your favorite

software tools that you use?

CodeWarrior®, Micrium RTOS,

Mathlab and IAR.

Have you always been

interested in practicing

medicine?

Yes. During my childhood, I visited

hospitals frequently and was thrilled

by the work the physicians did.

However, I always thought I had

a bad memory and at some point

I decided that medicine was not

for me. As it turned out, I was not

as bad as I thought at memorizing

information.

What is on your bookshelf?

I like to read non-technical books

so that I can rest my mind from the

things that I read on a daily basis at

work. I am reading Pedro Paramo

by Juan Rulfo, a Mexican author’s

short novel about death, and Genji

no Monogatari from Murasaki

Shikibu, a Japanese lady from the

court, which is sometimes called

the world’s first novel.

What made you decide to

study both electronics and

medicine?

It was always in my mind. I enjoyed

both things, so why not study

But besides that, I really enjoy

writing. I have just recently co-

authored a book based on Micrium’s
