2018 UNI STEM Camps under way!


The summer of 2018 is a time of exploration, design, and creativity for UNI's STEM campers!  

Panther Park - A 3D design, 3D printing, and Virtual Reality Experience is the newest camp to be added to our summer offerings.  This camp is designed to introduce 6th through 9th graders to careers in additive manufacturing through exploration of 3D modeling and printing and the use of robotics and virtual reality in industry.  The University of Northern Iowa Additive Manufacturing Center, at TechWorks, sponsored and hosted 2 sessions of this camp - one open to anyone and one for girls only.  Take a look at some of the camp activities:

Voice Research & Technology


The use of phone apps help us in our daily lives, in our businesses, and they entertain us.  We have our phones to help us know how many steps we have taken each day.  We have games on our computers to help us learn new languages, math skills, the list goes on and on.  Dr. Lisa Kopf of the Communication Sciences and Disorders department at the University of Northern Iowa is taking these ideas and applying them to her interests in voice research. 

Voice research includes the physical anatomy and physiology of the vocal folds (cords), disorders, vocal health, therapy, and the physics of sound.  One of the more common disorders is vocal nodules which are calluses formed on vocal folds due to excessive use.  Professions that use their voice extensively are at risk for this.  These careers include teachers, singers, coaches, sales people, and call center workers, just to name a few.

Dr. Kopf’s background in music and gamifying therapy has led her to the research and possible development of an application (app) to be used by people within these professions.  The app would be akin to a pedometer.  It would measure how and how much she uses her voice throughout a given day.

Published research has shown that nearly 1/3 of the workforce is at risk for voice disorders (Roy et al., 2005).  This is the basis for the research and development of an app where the user could monitor his/her voice so as to potentially avoid developing a voice disorder.   

The research begins with the end user as an integral part of the creation.  This approach, called user-centered design, involves multiple iterations (versions) of a design that are tested with potential users before a final design is created.  The goal of this approach is to develop a final product that will be intuitive and supportive of user goals.

Dr. Kopf started her undergraduate studies at the University of Virginia (UVA) with the intent of being a Speech Pathologist in a school system.  She was involved in choir and in her third year she had the opportunity to work with and meet professional soloists.  One of the soloists asked what degree she was pursuing.  After learning what her goals were he said that his friend “does that and works with singers.”  This opened up a whole new avenue of study for Dr. Kopf, one she had not thought about—combining her love for music and helping people with voice disorders.  Soon after this conversation, Dr. Kopf connected with Dr. Aliaa Khidr, a UVA faculty who specialized in voice.  Dr. Khidr became Dr. Kopf’s mentor, providing a welcoming environment and opportunities for undergraduate research.  

At the suggestion of her mentor, Dr. Kopf moved to Iowa to complete her masters at the University of Iowa.  The U of I Speech Pathology Department is well known the for its courses in voice disorders and ranked number one in the country (out of 224 schools) by US News and World Report (2016).  She worked as a full-time clinician in a hospital setting for two years before returning to graduate school.  She started her PhD at the University of Florida and finished at Michigan State University.  Because she wanted to see and experience different areas of voice, her PhD advisor, Dr. Rahul Shrivastav, was instrumental in allowing Dr. Kopf to explore multiple areas before deciding to focus on just one area.  She was able to narrow her focus through the relationships she developed with faculty, the gaming community, and the learning more about user centered design.  Today, Dr. Kopf is one of the few experts in voice and gamifying therapy.  She is hoping to inspire others to go in this direction of study as it is an exciting and new.

Although she has only been on the UNI campus since August of 2017, Dr. Kopf has found that she has amazing faculty and staff support which has helped her get settled.  She feels like she has an open line of communication with everyone so that she can ask anyone anything and they would be willing to help. 

Work-life balance is also important to the department.  She was able to come into an environment where she was able to structure her research and teaching to what works best for her allowing her to be a better researcher and instructor.  Her research is off and running with a lab with both graduate assistants and undergraduate support in collecting data.

She enjoys working with students and her favorite part of working with undergraduates and graduate students is their enthusiasm.  All the students she works with have been helpful, try their best, and work hard.  They have a willingness to learn and are very engaged in what they are doing. 

Dr. Kopf is interested in trying new things in the classroom and doing her best as an instructor to enhance her students’ learning.  She tries new and different activities.  She is continuously asking for feedback from students to learn what worked, how it worked, what things could make the class better in the future.

“Speech Pathology is such a broad field.  There is something here for everyone,” Dr. Kopf stated.  Speech Pathology is constantly changing as new discoveries are being made and more research being conducted.  The profession can lead a student to working in schools with children, hospitals, skilled nursing facilities, and rehabilitation clinics.   Professionals may work with those who have suffered from a stroke or brain injury, with those who may have a voice disorder, swallowing challenges or even people who stutter.  “There are so many avenues you can take in this profession.  I believe this is what makes it so cool.”

Ocean Adventurer


Emma Shipley Hiking Seven Sisters near Dover, UKEmma Shipley, a senior Biochemistry major, is near the end of her education at the University of Northern Iowa.  She has had many challenges and adventures at UNI and will soon be on a new adventure.  The question of what do you want to be when you grow up is one of the most common questions asked.  The answer to this question impacts the decision of where a student wants to go to college.   Emma made the decision to come to UNI because she wanted to be a social studies/history teacher.

Emma decided to change her major after three semesters because her dream job, she decided, would need to allow her to travel and to collect samples or analyze data outside or someplace other than behind a desk.  She had always thought “science was really cool.” Once she realized that she really enjoyed science and wanted to do more, she made the leap to pursue an education in Biochemistry.

Challenges, adventure, excitement, and opportunities have all been a part of her experience at UNI.  Emma has always liked a challenge as it gives “you the opportunity to stretch yourself to see how much you can learn.”  Physical chemistry, biochemistry, and organic chemistry have all been courses that have challenged her but she has found them to be valuable to her education.   Through taking these courses, she was able to find out which ones she clicked with and what area of science she truly enjoys. Some of the best courses she has taken at UNI have taught her how to problem solve.

Another course that challenged Emma was Evolution, Ecology, and the Nature of Science taught by Dr. O’Kane in the Biology Department.  This course was outside Emma’s comfort zone as it was based on class discussion of topics.  This had Emma terrified. She does not like to speak publically and really does not like being wrong, especially in front of others!  Dr. O’Kane helped Emma change her perspective and approach to failure. Unexpected answers are important too. Dr. O’Kane gives high-fives for wrong answers because that shows the student is trying.  In science, wrong answers teach the researcher more about the right answer. Bad results or data are also ok because this is part of the learning process. Success is ruling out wrong answers and discovering what will not work, lead to new ideas and discoveries.  Emma now appreciates when she is wrong and see this as one step closer to being right.

Adventure and excitement were rolled into one when Emma made the decision to spend a semester abroad.  This is something that she had wanted to do since Kindergarten, when someone came to her classroom and told of her own adventures in another country.  Emma’s mother encouraged her to wait until college to pursue this 6-year-old’s dream so that she did not miss out on any of her childhood .  Her mother also reasoned that it would be easier because many college students do this.  

In the fall of her junior year, Emma boarded a plane and headed to the southern coast of the United Kingdom to the town of Chichester.  During this semester she traveled and made new friends, in addition to her studies. Inside the classroom, Emma went back to studying history.  It is often difficult to study science abroad due to the different order and the way concepts are taught.  Each class was held once a week, so she only went to 4 classes a week.  Students are expected to do more outside of class.

Studying was not the only thing Emma did outside the classroom.  She traveled  as much as she could.  She is thankful for the weekly blog assignment she had to complete for her honors course because she can go back, read, and relive her adventures and funny stories.  Her favorite day in the UK was hiking the white cliffs of Seven Sisters near Dover. She had perfect weather for a perfect day on the southern coast.  Emma felt that this was a very valuable experience learning about herself and obtaining a deeper understanding of her own culture as well as other cultures, places, people, etc.

Emma Shipley Presenting her Undergraduate ResearchBack on the UNI campus, Emma had to buckle down with her coursework and got involved with some undergraduate research on campus.  She had the opportunity to work on the BioGeoChecmical Evolution of the Atmosphere (BETA) project. The three mentors on the project are Dr. Sebree of the Chemistry & Biochemistry department, Dr. Sedlacek and Dr. Shen, both of the Earth and Environmental Sciences department.  Together they are researching what compounds and elements were in the atmosphere at different time periods; early earth (4 billion years ago), the Devonian period (400 million years ago) and the present day. Other questions include: What kind of compounds could have been food for early life? What kind of plants were available? The method in which they are using to answer these questions has never been done used before, which made the research that much more exciting for Emma to be a part.  

Emma’s undergraduate honors thesis branched off the BETA Project and was titled Pre-Biotic Potential of Aerosols.  Another research project in which Emma was involved looked at the lead content in a Mastodon Tusk found in Iowa. She found that lead was present, however, the source was unable to be determined.  She said “that may be a project for a future student.”

Conducting research will continue after she graduates in May because Emma is headed for Connecticut.  She will be joining the PhD program at the University of Connecticut Avery Point Oceanography Department. She is very excited to be near the ocean and to learn and do research about something she loves.  She believes that important and small contributions are made to science everyday, impacting all of us, even if we do not realize it. She is looking forward to being apart of the scientific world and making her own contributions.
