Over the summer I was fortunate enough to spend six weeks in Cleveland, OH participating in the Summer Medical/Dental Education Program. There are multiple SMDEP sites all over the U.S. at varying dental and medical schools; the site I chose to attend was centered in the Case Western Reserve University School of Medicine.
Over the course of six weeks I had the privilege of attending multiple lectures, ranging from different groundbreaking studies in the medical field to insight on the process of applying to med school. Aside from guest lecturers we also were required to attend class. Each student was assigned a math, writing, physics, and chemistry course, and the classes we were placed in were contingent upon the classes we had already taken during the school year. In addition to class work, every student was assigned a public health group. Over the course of the program these public health groups were responsible with finding and proposing practical solutions to public health disparities, then presenting their topics in the form of a 20 to 30 page paper as well as a power point presentation.
However, the main experience that makes this program unique is the shadowing experience. Each SMDEP student, at the CWRU site, was given the ability to shadow 3-4 doctors in fields such as neurosurgery, plastic surgery, internal medicine, neurocritical care, and emergency care. This, in my opinion, was perhaps the one of the more useful experiences, in terms of understanding the day to day procedure of different doctors.

I have a summer research internship at the Center for Reproductive Medicine here in Mobile working with Dr. George Koulianos, MD and Dr. Suzanne Degelos, Ph.D. The Center specializes in many facets of reproductive medicine including several methods of in vitro fertilization as well as intrauterine insemination (IUI) in addition to general reproductive healthcare for couples and patients facing reproductive difficulties or infertility. My internship involves working as a lab tech with lab director Dr. Degelos by assisting in egg retrieval and embryo transfer procedures along with intracytoplasmic sperm injection (ICSI), which is the method used to fertilize eggs in vitro in the lab. Along with my lab tech responsibilities, I have been given my own project involving some data analysis and bioinformatics in order to help the Center publish an abstract that they have been trying to get out for several months now.
In the IVF world, a new technology known as physiological intracytoplasmic sperm injection (PICSI) has emerged since about 2012 which utilizes a special dish coated in media containing the protein hyaluronan. All normal morphological and functional sperm have hyaluronan binding receptors on their heads while eggs possess hyaluronan protein on their outer surface that bind during natural fertilization. Thus, PICSI dishes possess hyaluronan that allows for sperm binding in the dish and thus an embroylogist to select the best quality sperm for injection. My project has included analyzing all the patient records since 2012 when PICSI was first used here at the Center and comparing pregnancy outcomes to ICSI patients from the same time period. Many fertility clinics across the country are moving to this new method but unfortunately the sample size here at the Center as well as in other studies from around the country are not large enough to produce statistically significant results that prove PICSI is more effective and provides higher clinical pregnancy rates and more importantly successful delivery rates than standard ICSI.

I am currently participating in a six week summer internship with the East Carolina Heart Institute under the supervision of Dr. W. Randolph Chitwood ’72, the founder and director of the Institute. Aaron Gilani ’15 will work with Dr. Chitwood in July. In this internship, I observe and shadow Dr. Chitwood and several other doctors who work under him or alongside him. Whether it’s through clinics, labs, or OR cases, I am directly exposed to the everyday work of thoracic surgeons, cardiovascular surgeons, and other physicians who deal with thoracic issues. I witness open heart valve repair/replacement surgery, robot assisted minimally invasive valve repair/replacement surgery, and other thoracic surgeries. This internship allows students to catch surgeons in action while asking questions regarding anatomy, physiology, or just the everyday struggles and rewards of being a physician. I recommend that any student with an interest in pursuing a career in medicine should apply for this amazing opportunity. Dr. Chitwood and his staff love to teach students, and Dr. Chitwood loves his alma mater, Hampden-Sydney College.
This summer I am researching head and helmet impacts that can cause concussions in American Football (Football). Through a series of experiments I will obtain data on the intensity and location of head impacts an Offensive Lineman and Defensive Lineman may suffer. Once the analysis of the data is completed, I will be able to conclude which areas of an Offensive and Defensive lineman’s brain are most susceptible to trauma. Through the data I will monitor the frequency and intensity of impact on the areas of the brain that are most susceptible and then utilize that information to focus on protection for the areas of the brain affected. To obtain this data an accelerometer is enclosed inside a ballistic gel brain model and is used to collect the data needed for my study. This model gives me the ability to measure the intensity of the impact not only on the skull, but also on the brain. A drop test was conducted on a grass field from the average height of an offensive lineman (6’4”), and a defensive lineman (6’2”), in order to collect the intensity of impact through the accelerometers inside the brain. Once the data was collected, I placed the skull model on a variety of different helmets and ran the same experiment. This data will reveal which helmet type is best to protect the brain. From this data I will understand the susceptible areas of the brain. Later on, I hope to create a prototype for a helmet that protects Offensive and Defensive lineman from concussion brain trauma. As a college football player I am learning ways to extend my career in football and understanding how to protect football players from sport related injuries. I believe my research will impact the game of football and contribute to the protection other athletes can establish for themselves to prevent a possible concussion. I am passionate about the sport of football and envision these results helping me build a career in injury prevention. I foresee extending my focus of injury prevention to creating a helmet that protects all positions on the football field and then move to working on protection for other types of injuries that a football player or other types of athletes may sustain during their career.

This summer I have been researching head/helmet impacts in wide receivers and running backs. I have obtained data of intensity and location of head impacts for wide receivers (WRs) and running backs (RBs). After analysis of the data I have come to a conclusion of which areas of the brain are most vulnerable for each position: back, front, or side. The frequency and intensity of impacts to the specific areas of the head will determine the amount of focus on that area as far as methods of protection. After obtaining and analyzing this data I have set up the head/helmet testing. To obtain data for testing I have used accelerometers to measure intensity of impact and a synthesized ballistic gel to represent the brain in a skull model. Later in my research I hope to compare the effects of impact on different locations of an assortment of helmet brands to determine which helmets protect which areas of the brain more effectively. I have preformed dropped tests from an averaged height of 6 feet onto a grass field and collected data with the accelerometers inside the brains. I hope, at some point, to be able to move on to the design and construct new helmets for both RBs and WRs based on their more vulnerable locations of impact. As a collegiate football player I am very passionate about the sport and I am determined to achieve the best, most significant results. I hope to gather enough data to continue in the field of injury prevention and quite possible change the layout and construction of football helmets so players from youth to professional levels can play the game they love with less worry of receiving traumatic head injuries.
Josh and Grayland presented their genomic characterization of McFly, a bacteriophage of the bacterial species Mycobacterium smegmatis originally discovered on the H-SC campus in 2012 and named by Seth Ayers ’13, a past project participant. McFly resembles several bacteriophages isolated from across the U.S. but also has unique features such as the code for three tRNA molecules. By studying McFly along with the phages found at other schools, undergraduates like Josh and Grayland are contributing to authentic research spearheaded by a research group at the University of Pittsburgh that regularly disseminates findings through publication in peer-reviewed scientific journals.
Josh and Grayland received an Honorable Mention award at the end of the symposium, placing their poster presentation in the top 10 of over 70 student posted presented and placing them in the same tier as students from Johns Hopkins, Brown, and Carnegie-Mellon Universities. The SEA-PHAGES project will once again be in place at H-SC in the fall as a new group of biology students enrolled in Dr. Wolyniak’s Molecular and Cellular Biology course will attempt to isolate bacteriophage from the environment that target several species of the bacterial genus Bacillus.
