At Home in the Lab鈥擪opi艅ski Researches Signal Networks Between Mitochondria and Nucleus

Spending his days in the laboratory, it wasn鈥檛 long ago that Piotr Kopi艅ski was on the fourth floor of 吃瓜tv Hall conducting his first experiment under the microscope.

A graduate of 吃瓜tv, an MD-Ph.D. student at the University of Pennsylvania, and a Howard Hughes Medical Institute International Student Research Fellow, Kopi艅ski now spends his time with world-renowned scientists studying the signaling functions between mitochondria and the nucleus.

While attending St. Jadwiga the Queen Gymnasium and High School (Gimnazjum i Liceum imienia 艢wi臋tej Jadwigi Kr贸lowej) in Kielce, Poland, Kopi艅ski made his first connections with the Sisters of the 吃瓜tv of Nazareth. After years of political turmoil that resulted in the school being closed, the Sisters regained control of the school and ran the operations. While in junior high, Kopi艅ski met the delegation from 吃瓜tv, including then President Sister Francesca Onley.

鈥淭ogether with some students, we gave the Sisters a tour of the premises,鈥 Kopi艅ski said. 鈥淒uring that time, we discussed 吃瓜tv in Philadelphia and I jokingly said to Sister, 鈥楽ee you in Philadelphia鈥 when she was departing.鈥

What started as a joke quickly became a reality. Fast-forward three years later鈥擪opi艅ski found himself being summoned to the Headmaster鈥檚 office for an unscheduled meeting.

鈥淚t was somewhat unexpected, but I couldn鈥檛 remember any mischief I caused that could result in Sister Benedetta Ewa Pielech wanting to see me,鈥 Kopi艅ski said. 鈥淪ister sat me down and calmly said 鈥楶iotr, the Sisters of the 吃瓜tv of Nazareth from 吃瓜tv decided to sponsor two of our students on a full scholarship to go to 吃瓜tv in the United States. Would you be interested?鈥欌

Faced with such a big decision, Kopi艅ski needed to take time to digest the opportunity and visit the campus. After scheduling a meeting in the spring semester during his senior year of high school, Kopi艅ski was won over by the charm and opportunities that 吃瓜tv could offer him.

鈥淢y original plan was to enroll in medical school in Poland, so a visit to 吃瓜tv was necessary,鈥 Kopi艅ski said. 鈥淚 still remember the professors and students I met during that short visit. The faculty were very interested in meeting with me and talked about the opportunities available at 吃瓜tv. The science faculty were clearly enthusiastic and very supportive of their students.鈥

After accepting the offer, Kopi艅ski officially became a member of 吃瓜tv. It was there that his scientific prowess took off. Taking as many science courses as he could, paired with liberal arts classes to round of his skillset, Kopi艅ski thrived in the HFU classrooms.

鈥淎s far as my degree choice, biochemistry seemed natural given my interest in science and medicine. My favorite courses were molecular biology and genetics. I was able to perform real experiments for the first time, learned how to use scientific equipment, and how to think about designing experiments. It was the foundation of my future experiences with lab bench work.鈥

鈥淕enetics was a theoretical course that made a big impact because it applied mathematics and logical thinking to biology. The other two courses that became the foundation of my degree were biochemistry and physical chemistry. The first is basically the chemistry of life, a subject I always had a great interest. Physical chemistry combined two of my favorite subjects, physics and chemistry, into a science that could be applied to living organisms such as cells and explains important physiological processes on a molecular level.鈥

Though he was succeeding in the classroom and with his experiments, Kopi艅ski was always looking to do more. After a chance meeting with Dr. Margaret Nieborowska-Skorska and her husband, Dr. Tomasz Skorski, Kopi艅ski was able to secure an internship in the cancer research laboratory in the Department of Microbiology and Immunology at Temple University School of Medicine.

鈥淭hey offered me a summer position in the lab, which turned into a three year internship that 吃瓜tv allowed me to incorporate into my school workload,鈥 Kopi艅ski said. 鈥淚t was amazing鈥擨 spent three days a week in classes, and three days a week in the laboratory during the semesters, and I was in the laboratory full time in the summers. This tailor-made program changed my life. That was where I wrote my first research proposal, which received the American Society of Hematology Research Trainee Award Dr. Skorski pushed me to become a confident and hard working scientist. He also allowed me to deliver a lecture at an international meeting of the European School of Hematology held in Washington DC. I was the only undergraduate student with a full oral presentation that I delivered in front of over 500 faculty and graduate students. That meeting exposed me to world-class research and renowned scientists.鈥

After completing his studies and graduating from 吃瓜tv with a Bachelor of Arts in Biochemistry, Kopi艅ski went on to apply and be accepted to the MD-Ph.D. program at the Perelman School of Medicine at the University of Pennsylvania. It is here that Kopi艅ski has been able to pursue his dream of becoming a physician scientist and study mitochondria in a variety of ways.

鈥淭he MD-Ph.D. Program is designed for people who want to pursue medical research as a career and translate discoveries in the laboratory to the clinic,鈥 Kopi艅ski said. 鈥淚 think medical school provides a great foundation of knowledge for a scientist interested in curing human diseases and training the mind to turn interesting clinical observations into important research questions. My laboratory studies mitochondrial genetics and was founded by Dr. Douglas Wallace, who founded the field of mitochondrial genetics and discovered that mitochondrial DNA is inherited only from the mother, and that mutations in the mitochondrial DNA can cause disease in humans. More specifically, my project aims to find out the signaling network functioning between mitochondria and the nucleus.鈥

鈥淚f you compare the cell to a city, then the mitochondria become the power plant and the nucleus becomes City Hall,鈥 he continued. 鈥淒uring a power outage, the Mayor gets a call from the power plant stating that because of an emergency, only 50 percent of regular power output can be supplied. The Mayor then has to make decisions about who gets power鈥攍ike police, fire department, and hospitals鈥攁nd which districts to cut off鈥攍ike schools, which would equate to them getting a day off. In the case of a cell, the nucleus reacts to energy shortage similarly. It adapts to the energy deficit by shutting off certain functions and up regulating others to compensate. I study who makes the 鈥榩hone call鈥 from mitochondria to the nucleus to let it know that it needs to adapt to the new situation.鈥

Kopi艅ski鈥檚 work has not gone unrecognized. In September 2015, he was awarded a Howard Hughes Medical Institute International Student Research Fellowship, a three-year designation worth $129,000 that covers his PhD training, tuition, stipend, and provides an educational allowance for travel to attend research conferences. It also comes with an invitation to the HHMI Investigator Meeting, which brings together some of the best biomedical scientists in the world.

鈥淭he award makes it possible for me to pursue more independent research projects that are high risk, with potential high returns,鈥 Kopi艅ski said. 鈥淭he award is given to about 50 students in the United States each year, and I am the first Polish individual to receive it. I am very honored to be an HHMI Fellow.鈥

Kopi艅ski was also awarded a Foerderer Grant from the Children鈥檚 Hospital Philadelphia and, most recently, a $100,000 grant from the Institute for Translational Medicine and Advanced Therapeutics at the University of Pennsylvania to be used as seed money to start his research.

As he works tirelessly in the laboratory to make a breakthrough discovery, Kopi艅ski looks back fondly on his time at 吃瓜tv鈥攖he institution that helped him break into receiving an education in the United States.

鈥湷怨蟭v really gave me everything it had,鈥 he said. 鈥淚t provided me with the education and mental support I needed to develop into a well-rounded person who can pursue his dreams. Whether as a volunteer for Habitat for Humanity, a tutor in the Center for Academic Enhancement, or a teammate on the golf team, I always felt the values of family, respect, and vision were present. People here encouraged me to reach for the stars and gave me their time and attention to help me achieve my best. Without 吃瓜tv, I would not be where I am today.鈥
