David Park.png

David is a third year dental student at the University of Pennsylvania. He received his B.S. degree in biological sciences from the University of California, Irvine. He is a recipient of the Health Professional Scholarship Program and will be serving in the U.S. Army after he graduates. David’s father is a retired colonel in the U.S. Army, so David had the opportunity to live all across the globe such as in Würzburg, Germany and Seoul, South Korea. As someone who spent his whole life traveling, David fell in love with exploring foreign countries. This hobby combined with his passion for community service led him to go on many mission trips across the globe. His most recent mission trip was to Embu, Kenya in 2019 where he served as a dental assistant. David’s interest in oral surgery has led him to start a Passing the Scalpel chapter at the University of Pennsylvania with Dr. Corissa Chang and other fellow dental students. He hopes to deepen his knowledge of the specialty, connect with professionals across the globe, and inspire the next generation of students to join him on this path.

He attended the University of Pennsylvania for undergraduate as well, where he played NCAA Division 1 golf and earned a B.A. in Science, Technology and Society.

With influence from his entire family, along with a passion for problem solving, medicine, and surgery, Cody hopes to continue his education as an Oral and Maxillofacial Surgeon. He was drawn to Passing the Scalpel because of the opportunity to expand his knowledge of various OMFS procedures and connect with pre-OMFS students, current residents, and attendings. He is interested in a well-rounded academic career in oral surgery and believes Passing the Scalpel will help him to achieve this goal in the future.

Joshua Kim.png

Joshua is a third-year dental student at University of Pennsylvania. Before coming to Penn, he was raised in Edmonton, Alberta and attended University of Alberta for his undergrad. Joshua found interest in oral maxillofacial surgery as he found himself loving the integrated components of dentistry, medicine, and surgery into one profession. Passing the Scalpel is a project that Joshua found strongly resonated with his enthusiasm as an educator and assisting his peers in pursuing their goals. He was drawn to this project because Joshua wanted to be at the forefront of bridging the gap between dental students and the profession of oral maxillofacial surgery. In Joshua’s spare time, he enjoys snowboarding, skiing, model crafting, and taekwondo. Joshua is very excited to be part of an organization that loves to inspire future generations of oral maxillofacial surgeons and provide us the opportunity to connect with many oral maxillofacial surgeons in the world.

Shikha Patel.png

Shikha is a second year dental student at the University of Pennsylvania School of Dental Medicine. She was born in Queens, New York but lived in Southern NJ for most of her life. She attended Stockton University and earned a Bachelor of Science degree in Biochemistry and Molecular Biology. Shikha’s interest in dentistry stemmed from having an amazing dentist and mentor who she worked with for almost eight years before starting dental school. Her interest in surgery started at a young age as well and was solidified after assisting with many surgeries while working in private practice. Shikha has always enjoyed science, working with her hands, and working on a team, so choosing a career in Oral and Maxillofacial Surgery was always the right decision. After researching about Passing the Scalpel, she knew that she wanted to be a part of this amazing organization because it would allow her to learn more about oral surgery while connecting with like-minded individuals. In her free time, Shikha enjoys spending time with friends and family, crocheting, and going on long runs.

Jacob Cole.png

Jake is a current second year dental student at the University of Pennsylvania School of Dental Medicine. He received his B.S. in Biology and minor in chemistry from Wake Forest University in 2019. Jake’s interest in oral surgery grew through multiple mission trips to Honduras during his high school and college years. The Rice Foundation, based out of his home-town of DuBois, PA, headed these mission trips. The local oral surgeon founded this organization; and the overwhelmingly positive impact his work had on the people of Honduras inspired Jake to pursue a career in OMFS.


Jake is passionate about the field of oral surgery and Passing the Scalpel allows him to connect with other professionals who feel the same way. He finds the side-by-side collaboration and mutual pursuit of knowledge/skills provided by Passing the Scalpel to be invaluable. Outside of dentistry, Jake enjoys weight-lifting, spending time with friends and family, and leading an on-campus Bible study.
