If you are a student finishing your master's degree and
starting Ph.D. studies, you will soon encounter the challenges that
face most science students during the transition. Chief among these
challenges is learning how to think and act like an independent
scientist. This article highlights my personal experiences at this
crucial point in my academic career.
After completing my master's degree in biology at the University
of Texas at Brownsville, I began the Ph.D. program in physiology at
the University of North Texas Health Science Center. Getting my
master's degree had gone smoothly, so I thought that, although the
Ph.D. program would probably be more difficult, I would handle it.
And I did handle it--eventually.
As "principal investigator" of your own piece of lab, you have
to think about and do things to keep the lab up and running.
During just the second month of my studies, I became
overwhelmed--very, very overwhelmed!--by coursework and other
factors. One key source of stress was the biomedical core class.
The class was designed to teach the fundamentals of immunology,
cell biology, molecular biology, pharmacology, and many other areas
of biology. These disciplines were taught in 1 to 2 month
timeframes; we had to learn all these subjects in one academic
year.
Of course there were other things to worry about. These included
my research project, a looming oral examination in physiology, and
management of living expenses on meager pay. Life was
stressful!
To survive, I developed a safety mechanism called "Let my
graduate mentor bail me out." I would give him my problem and he
would solve it. For example, I'd tell him I was having trouble
understanding the course material and he would explain it to me. Or
I would say I was having difficulty analyzing data and he would do
it for me. This worked for a couple of months, but one day it all
ended.
Bursting My Bubble
I went to his office expecting my daily dose of salvation and
instead he gave me a disappointed look and said, "Martin, one day
you will have your own research lab. One day you will have to solve
your own problems. If I keep giving you the answers you will never
learn to be an independent scientist. You have to pretend this
isyourlab. You have to do whatever you can to solve problems
and make things work." I felt like a worm and wiggled out of the
room a very embarrassed graduate student.
But I learned a very important lesson that day. To be an
independent scientist, you have toactlike an independent
scientist. This was very hard for me, because during high school,
college, and my master's degree, I was used to being bailed out by
my teachers. Looking back at those years, I realize that I used the
excuse of being a product of a school system that was not as good
as others in the U.S. Rather than working hard to overcome my
academic deficiencies, I used my lack of preparation as a crutch.
At first, I continued the pattern as a Ph.D. student, and it took a
sound shaking by my mentor to let me know what my problem was.
During undergraduate and master's education, being independent
is not really stressed. You are mostly thinking about learning from
books and passing tests. Knowledge is dished up; you just have to
chew and swallow. But science is not about learning information
from textbooks. Science is about discovery. Scientists create ideas
and test their ideas to arrive at the truth. Learning to do this is
what Ph.D. training is all about.
The key word is independence. You must learn to do the work of a
scientist independently. How? By taking my advisor's advice and
pretending the lab is yours. As "principal investigator" of your
own piece of lab, you have to think about and do things to keep the
lab up and running. Experience is the best teacher. Start
practicing as soon as you can.
Key Pointers for Gaining Independence
These strategies helped me with my transition to scientific
independence.
-
Plan and execute.Be active in the planning and
performance ofallaspects of your research project. This
includes experimental setup and execution, data analysis,
manuscript writing, data management, etc. It's your research, so
learn to do it and take responsibility for it.
-
See the whole picture.Develop a sense of the entire
spectrum of the research process. Sit back and ask yourself what it
takes to go from an idea to the finished product. Once you grasp
the steps, you are no longer clueless. You will know what needs to
be done next, and you won't have to rely on your mentor to light a
fire under you. Or in you.
-
Develop a troubleshooting mentality.Try to solve problems
on your own. This type of thinking will serve you well in your own
lab. It will also help you grow as a scientist. It is better to
have the ability to solve problems than to sit and worry about who
or what will help you.
-
Go out of your way to learn.It's no longer about learning
what's on the test long enough to pass it. It's about learning all
aspects of science that can help you with your research. Go out
there and read with a purpose. Read and learn everything you can
about the techniques you will perform, the equipment you will use,
and what has been done in this area of research in the past. When
you know more about your project than your advisor, you're almost
ready to graduate.
-
Be proactive.Be the first one with the idea. Be the first
one to solve the problem, or the person who initiates discussions
in lab meetings and organizes activities, such as journal clubs and
inviting seminar speakers.
When you do these things--and do them first--you'll be a leader
in the lab. But the main goal is to be the leader of your own
learning. You must take charge of your Ph.D. training and do all
the things necessary to make your research program successful. I'm
grateful to my advisor for giving me a dose of "tough love." It was
exactly what I needed to help me focus my attention on my research
career. I hope my experiences will help other graduate students in
their quest to becoming independent scientists.
