The Peppas Factor: Educating Future Leaders

Training the Next Generation

Having taught for more than 30 years, Peppas has created a constellation of leaders in the biomedical, chemical and pharmaceutical engineering fields.

“Under Peppas’ guidance and mentoring, his students have gone on to become outstanding scientists, invent products, lead companies and become dynamic educators,” said Gregory L. Fenves, dean of the Cockrell School of Engineering.

Indeed, of the more than 800 undergraduate, graduate students or postdoctoral and visiting scientists who have studied under him, 55 are now professors, 23 are professors of medicine, 31 are attorneys and more than 110 are now high-ranking executives at major companies.

Inside his industrious lab, Peppas and his students have together developed treatments that have improved the lives of people dealing with serious medical conditions, as well as invented health care products that are used by millions of people everyday.

“I’m very proud of the problems we have solved here,” Peppas said. “This laboratory, in a synergy with teaching, has solved problems all the way from vocal cord disorders, contact lenses, intraocular contact lenses, drug delivery devices and materials for artificial hearts.”

In addition to Peppas’ lab discoveries, it’s his genuine passion for teaching and concern for his students that have endeared him to so many of his past students.

Take the story of Jennifer Sinclair Curtis, who met Peppas when she was an undergraduate at Purdue University. He mentored her during critical junctures in her career, such as going to graduate school, getting a faculty position, writing successful proposals and getting promotions in academia. She is now an associate dean for research and facilities the University of Florida’s engineering school.

“There could be no greater supporter or mentor. When you work with Nicholas, you are ‘his’ for life. He keeps up with your career, your family, your life,” Curtis said. “As an example, two weeks ago, he sent me an e-mail regarding my son’s birthday. What other advisor or former professor would do that?”

As many of his students know, he spends a good deal of time nominating undergraduate and graduate students for awards, writing letters of recommendation and helping them secure internships where they can further their careers.

Without Peppas’ help and encouragement, “I would not have been able to get where I am today — studying a type of cancer therapeutic as I work toward my Ph.D. in chemical engineering at MIT,” said his former student Katie Maass, a UT Austin graduate.

During his career, Peppas has made a point of hiring promising undergraduates to work in his lab.

One major reason that Rebekah Scheuerle wanted to go to UT Austin was to work with Peppas on oral drug delivery. This spring, she was one of a small group of students nationally to receive the prestigious Gates Cambridge Scholarship.

“I was really passionate about getting into a research lab at a really young age and wanted to work with Dr. Peppas, specifically,” Scheuerle said. “He likes talking to freshmen and training them, so that at the end of the four years they’re independent scientists.”

Whether he’s leading a Socratic discussion in class or explaining to a group of freshmen the fields of chemical, biomedical and pharmaceutical engineering, Peppas naturally captures an audience with his dynamic presence.

“I think I can teach the most difficult mathematical equations, but I always connect it to a real case,” Peppas said. “You excite them not only with engineering, but with health care policy and lowering the costs. How much does this product cost? Why $10, why not $2?”

Instead of just delivering dry curriculum, he engages with real-life examples of people struggling with a disease, or a particular treatment that takes a toll on a body.

“When you have a diabetic patient taking injections, we all assume that this is a way of life. I come in and I say, ‘No, we should not accept that this is the best way or the only way,’” he said. “Let’s come up with something else.”

For all his contributions to medicine and engineering, Peppas said seeing his students succeed has been the most rewarding part of his career.

“Of course I’m proud of the products and the medical devices and seeing patients use them,” Peppas said. “But, still, the students are more important to me.”
