Catherine Michelutti, a junior in Bioengineering and Wharton and fellow in the Stavros Niarchos Foundation (SNF) Paideia Program, shared her virtual internship experience with the Orion Organisation, a healthcare NGO based in South Africa that provides for “the educational, training and therapeutic needs of children, youth and adults living with physical, psychosocial challenges, intellectual and neurological disabilities”:
“My internship with the Orion Organization has prompted me to reflect on my identity in terms of where my passions and future career interests lie. My previous work experiences have all been in biomedical research fields, which is something I’m passionate about and want to continue doing throughout my career. However, working with Orion has opened my eyes to the realms of interdisciplinary work that comes with operating a healthcare NGO and the joys that come with it.”
Coevolution is all around us. Think of the elongated blooms that perfectly accommodate a hummingbird’s slender mouth parts. But not all examples of species influencing one another’s evolutionary course accrue benefits to all parties. Tradeoffs are part of the game.
This summer, sophomores Linda Wu of Annandale, Virginia, and Nova Meng of Akron, Ohio, researched an coevolutionary scenario with benefits as well as costs for the species involved. Their work, supported by the Penn Undergraduate Research Mentoring Program (PURM) and conducted in the lab of biology professor Corlett Wood, has examined the relationship among plants in the genus Medicago, beneficial bacteria that dwell in their roots, and parasitic nematodes that try to steal the plants’ nutrients.
The Center for Undergraduate Research & Fellowships provides students in the PURM program awards of $4,500 during the 10-week summer research internship. Wu and Meng stayed busy through those weeks. Whether evaluating plants in a soybean field in Michigan or tending to hundreds—even thousands—of plants in the greenhouse at Penn, these aspiring researchers built a foundation for future scientific endeavors with hands-on practice.
“It’s been an amazing experience,” says Wu. “I’ve always been interested in genetics and evolution and have found parasitic relationships in particular really interesting. I like reading about weird parasites. This summer I’ve gotten to participate in lab meetings, read books about coevolution, and expand my knowledge about the topic.”
Mentored by Ph.D. student McCall Calvert, Wu spent the summer focused on the parasites in the Medicago model system the Wood lab uses. “I’m trying to see if those nematodes are specialists or generalists, if they’re locally adapted to their host plant or open to parasitizing on different species,” Wu says.
To do so, she’s grown pots and pots of plants in the Penn greenhouse, experimentally infecting Medicago plants as well as other species, such as carrot and daisy plants, with nematodes, to measure the degree to which the parasites flourish.
Meng’s project looked at the bacterial side of the coevolutionary relationship. Overseen by lab manager and technician Eunnuri Yi, Meng looked at four strains of bacteria, known as rhizobia. Two strains are nitrogen-fixing, giving their associated plants a crucial nutrient to promote growth, while the other two do not seem to contribute nitrogen to the plants, and instead exist as parasites in the plants’ roots. “I’m looking at what happens when we infect the plants with nematode parasites,” Meng says, “to see if the plants that are open to mutualistic rhizobia are more susceptible to the nematode parasites.”
Linda Wu is a sophomore pursuing an uncoordinated dual degree in business, energy, environment, and sustainability in the Wharton School and in biology with a concentration in ecology and evolution in the College of Arts and Sciences at the University of Pennsylvania.
Nova Meng is a sophomore majoring in bioengineering in the School of Engineering and Applied Science at Penn.
In this guest post, recent Penn Bioengineering graduate and master’s student Casey Colleran writes about her experience in virtual internship at Janssen Pharmaceuticals.
During the summer of 2020, I was privileged enough to join the Global Regulatory Affairs team at Janssen Pharmaceutical Companies of Johnson & Johnson. Despite the uncertainties brought on by COVID-19, Janssen was able to bring together a group of five interns to participate in this virtual internship. This remote opportunity provided me with a valuable understanding of Regulatory Affairs, and the pharmaceutical industry. Throughout the 11 weeks, I was able to work alongside Regulatory Scientists in several functional areas of the organization. I learned about the regulations that govern the pharmaceutical industry, and the strategy that goes into communicating with the FDA and other health authorities.
As we rotated through each of these functional areas, myself and the other interns were also able to observe how the pandemic impacted the organization. We were asked to develop our own solutions on how to address these new challenges. Through this task, I learned how to present information in a meaningful way, analyze anecdotal data, improve processes, and communicate across different networks. As a team, myself and four other interns developed probing questions to help us understand how the COVID-19 pandemic has impacted the regulatory landscape, and the different strengths and opportunities employees observed in Janssen’s response to the pandemic. As we rotated through the different functional areas of Janssen’s Global Regulatory Affairs group, we used that time to ask our questions, and make note of anecdotal data that would provide us more insight as to how to address the new challenges brought on by the pandemic, and the virtual work environment. We then created a “COVID-19 Playbook” which broke down the main themes we had heard in our responses, such as the need for a more flexible organization, more efficient and effective communication, improved connectivity in the virtual workplace, and more. We developed suggestions on programming and guidelines that would help strengthen each of these areas, and presented these suggestions to the Senior Leadership Team.
Leadership development opportunities were also focal to the internship. I was paired with several amazing mentors who provided me with personalized feedback on how to become a more effective leader. The culture of the organization was extremely welcoming, and I cherish the relationships that I was able to build with my colleagues, so much so that I joined Janssen as a part time contractor this past year. Through this role as a contractor, I have been able to learn more about the day-to-day activities of a Regulatory Scientist through hands-on activities. As a contractor, I have been an integral part of a new “FLEx” Program. As a part of this program, I offer support to Regulatory Scientists by taking on their more routine submissions, giving them the opportunity to work on more strategic based activities, and focus on their personal growth and learning. It has been such a wonderful experience to work closely with these Regulatory Scientists who are still early in their career, as we have been able to learn from each other as well. It has also given me a greater understanding of the regulatory landscape, and by taking part in this new program I again get to see much of my feedback be considered and implemented.
I am so grateful that I had the opportunity to work in such an amazing environment, developed so many skills, and built a network that led me to additional opportunities in Regulatory Affairs at Janssen.
