Going to Drexel University? Consider Medical Research

“Speaker 1: Drexel university in Philadelphia
caters to some of the finest engineers in the country. The biomedical engineering department is doing
particularly well. Graduate student and researcher, Youhan Sunny,
discusses his work within the department. Speaker 2: So, my name is Youhan Sunny. I’m 30. I’m doing a PhD in biomedical engineering
at Drexel. My interest is in ultrasound and specifically
therapeutical transducers. What is involved in my research, its mostly
building the transducer . So normal out the transducers are used for diagnostic purposes. You use the transducers to look at stuff inside
your body or its also used outside like oil pipes, to see if there are cracks. That’s the most common acceptable uses of
ultrasound. What I do is, make the same or similar ultrasound
transducers to treat things. So, there is diagnostics and there is therapy;
diagnostics is trying to determine what’s wrong, and therapy is trying to fix what’s
wrong. So right now, what I’m trying to do is make
transducers for ultrasound to fix things and not necessarily to look at what’s wrong. So the science behind what I’m doing is very
simple, if you look at it from a physical perspective. So what I’m doing is taking something called
a transducer and any transducers are the simplest devices which convert one form of energy to
a different form of energy. So anything and everything that you see around
is a different use a transducer. If you look at a wall clock, that’s a transducer,
as in its taking the energy from a battery and its showing you time. So its transducing – one form of energy to
something entirely different. That’s exactly what I’m doing. I’m taking a transducer which converts electricity
into pressure waves or sound waves. So the device I’m making is very similar to
a speaker if you will, which you give it a signal, voltage, excitation, and then it produces
a sound. The transducer I’m building does the same,
the exact same thing. It takes an electricity and makes sound, the
only difference is, that the sound it makes is not audible to humans. Speaker 1: Youhan is very dedicated to his
research. He explains how his life led up to his career
in the biomedical engineering field. Speaker 2 There is no short answer to that. There is whole long story why I got involved
in biomedical research. But, my undergrad was in electronics and biomedical
engineering, which is like saying to in India that its electronics and communication, which
means you do electronics and then your specialization is in communication technology, like you know,
cell phones or towers, antennas, that kind of things. My was in electronics and the concentration
was more in biomedical engineering, and devices related to the medical field. So that is a reason why I got into the whole
medical research and medical instruments, and which is why I’m doing the same thing. Speaker 2 : Do I enjoy my job doing research? Yes, I enjoy my job doing research. First of all I enjoy it because it is very
open or the questions are open-ended and the work that you do is also open ended and there
is a lot of leeway in what you want to do, and you are doing things different in a way,
and you are trying to do new things, which is what is very interesting to me. You are always challenged by things. What’s creative is, that what I’m doing is
something new, its something that nobody has ever done before or nobody has ever attempted
to do before. So, yes, its also I’m doing something based
on the theories or the principles that are already established and using it to do something
new and different. Honestly, what drives me to work hard is,
one thing is you see the transducers that I’m trying to build being used practically. I mean, making something for research and
doing research and making something rudimentary, a lot of different people, a lot of people
are doing the same thing. You do something, you make, you know you find
out something, then you just leave it at that. What drives me is to see it to a further stage
where its actually helping people and its actually, in a more commercial stage where
people actually have access to the newer technology that’s being developed through research. Lot of times you have research and that’s
totally separate from the clinic or the clinical aspect of things that never really get to
the people. And there are a lot of technologies out there
like that. So what drives me is to make it better, so
that it can actually be used to help people. Speaker 1: With some complications in the
past, his project has been overall very successful. The transducers will some day benefit not
only Philadelphians but everyone able to walk into a drug store. Speaker 2: Well, I hope to achieve a Nobel
Prize. But, seriously, I want to make something that
will help people in the end. And, it is working out fine for me because
the transducers I’m using, is actually being used in human trials, so they are actually
being used on humans to treat people with actual needs. They have chronic wounds that don’t heal on
their own. They have these wounds for years and they
never heal, and limited human study that we did, we proved that by using the transducer,
it can he healed. So the wounds that were treated with the transducers
healed versus the ones which were not treated by transducers. So in the end, what I’m making is being used. We are trying to do more trials to make it
more effective, and so as to actually make it into a commercial device. But I’m happy that its being used in a useful
way for people, to help people. So yes.”
