College of Science Alumni

Science that serves the common good.

Each year, world-renowned faculty from the College of Science welcome students from around the globe. Eventually, these young men and women will transform from students into scientists, many of whom, upon graduation, will spread back out to the four corners of the globe. There, these alumni will take the knowledge they learned during their time at Notre Dame and, along with a Fighting Irish spirit and a belief in service to justice, will make the world a better place. Some alumni are already doing it.

And it’s not just those outside of the University who benefit from the heart and hard work of the College’s alumni, as Notre Dame’s unparalleled alumni network is bringing their real-world experience to the College’s current students by providing them with valuable career advice as well as opportunities for research experience with alumni at universities, hospitals, and other laboratories.

Below, read about what some of our alumni are doing with the knowledge they gained at Notre Dame. 

Applied and Computational Mathematics and Statistics 

Paul Baranay Alumnifeature

Paul Baranay '12

Paul Baranay earned his Bachelor of Science with a double major in biological sciences and applied and computational mathematics and statistics. During his time at Notre Dame, Baranay took advantage of many research opportunities. He worked with Steve Buechler, professor of applied and computational mathematics and statistics, on cancer gene network analysis, as well as Frank Collins, the George and Winifred Clark Chair in Biological Science, and Scott Emrich, assistant professor of computer science, on malaria research. Baranay also has worked with Michael Schatz, assistant professor, at Cold Spring Harbor Laboratory in New York, to study genome assembly. In addition to his research projects, he served as Co-Editor-in-Chief for Scientia, Notre Dame’s undergraduate journal of scientific research.

Baranay is now attending Yale University and working towards a Ph.D. in Computational Biology and Bioinformatics, focusing on human disease using large-scale genomics data. This area of study incorporates a variety of different approaches and disciplines, such as data mining (computer science), network models (applied math), and cellular mechanisms (biology and biochemistry). Ultimately, he hopes to integrate computational data with experimental verification to better understand the genetic risk factors underlying disease.

Biological Sciences

Dr. David Coulter '69

Dr. David Coulter '69

Look at a person with a disability, and it’s often easy to see what makes them different from others.

Dr. David Coulter can see those things in the patients he has worked with for decades. But he also sees one thing that makes them, and all humans, the same—their spirits.

Coulter says recognizing that is a lesson he got from Notre Dame, where 50 years ago he explored what it meant to be human and to be himself. He learned it through reflection, many caring mentors and the opportunity to take classes in a wide variety of fields, sometimes auditing classes in which he wasn’t able to enroll.

“I was a kid. I was searching for answers. Notre Dame gave me the space and the freedom to help find those answers. I looked everywhere I could to find those answers,” he says. “Notre Dame was always a welcoming and open space in a way no other college could be.”

Following his passion for all things tied to nature, Coulter earned a bachelor’s degree in biology in 1969. But he could also be found bouncing questions off professors and priests when he sat in on philosophy and theology courses.

Dr. Thomas Quinn '69, '70

Thomas Quinn ’69, ’70 has spent more than 30 years studying the transmission and spread of HIV/AIDS. Now a leader in his field, director of the Johns Hopkins Center for Global Health, and associate director for international research at the National Institute of Allergy and Infectious Diseases, Quinn traces his success back to his time at Notre Dame.

“From high school onward, I was fascinated by biology,” he says. Though he completed a variety of course work as an undergraduate in the life sciences, a parasitology course taught by Prof. George Craig proved to be his career-defining moment. More...

Sami Assaf

Sami Assaf '01

Sami Assaf never realized she would pursue a career in mathematics until she came to Notre Dame. She originally began her undergraduate career as a program of liberal studies major.  Her sophomore year, she took Linear Algebra class and realized how much she loved mathematics, so she registered for all of the core sophomore honors mathematics classes the next semester. “After taking classes with Peter Cholak and Frank Connolly my sophomore year, I was so enthralled with the beauty of mathematics that I changed my major,” explained Assaf. She was admitted into the honors mathematics program her junior year.

In addition to her mathematics courses, Assaf was also a member of the Seminar for Undergraduate Mathematics Research (SUMR), a program for the most gifted mathematics students at Notre Dame who intend to do post-graduate work in the mathematics series. She graduated from Notre Dame in 2001 with a double major in honors mathematics and philosophy. She went on to earn her Ph.D. from the University of California Berkeley in 2007. Assaf is now the Gabilan Assistant Professor of Mathematics at the University of Southern California and her current research program is focused on developing the theory of dual equivalence graphs, which provide a combinatorial tool for establishing the symmetry and Schur positivity of a function expressed as a sum of quasisymmetric functions.

Charles Misner

Charles Misner '53

Misner is professor emeritus of physics at the University of Maryland, where he started teaching in 1963. In 1993, a collection of papers in his honor, Directions in General Relativity, was published. He is a Fellow of the American Academy of Arts & Sciences.Charles W. Misner entered Notre Dame with the Class of 1953, earned his Bachelor of Science in Physics in three years, and did four-fifths of his graduate coursework on campus the next year before going to Princeton for his Ph.D. His landmark book Gravitation, written with Ph.D. advisor John Wheeler and fellow student Kip Thorne, was first published 40 years ago, has never gone out of print. His work provided early foundations for the study of quantum gravity and numerical relativity. He wrote “The dynamics of general relativity,” a summary of papers on a formulation of general relativity, with Richard Arnowitt and Stanley Deser. That pivotal work on formalism, published in 1962, is cited in the field with their initials ADM.


Jeff Drocco '04

At Notre Dame, Drocco won a Goldwater Scholarship, the most prestigious award in the U.S. conferred upon undergraduates in the sciences. He then moved to Princeton for his Ph.D. work, where he also held a Department of Energy Computational Science Graduate Fellowship.  A biological physicist, he completed his dissertation on pattern formation in development, working in the laboratories of his advisor David Tank and Nobel laureate Eric Wieschaus '69.Jeff Drocco is a physicist at Los Alamos National Laboratory (LANL). His affiliation with LANL began early: as an undergraduate, he joined a collaboration between Notre Dame physics professor Boldizsar Janko and LANL scientists Cynthia Olson Reichhardt and Charles Reichhardt, working on computational studies of vortices and granular matter.

In 2011, Drocco returned to Los Alamos as a Director's Fellow in the Physics of Condensed Matter and Complex Systems Group. His most recent projects include modeling the dynamics of swarming microorganisms, as well as studying the effect of nanoparticle aggregation on toxicity to human tissue.

"Notre Dame planted the seeds of scientific curiosity in my mind and introduced me to the art of using the principles of physics to study diverse aspects of the natural world," Drocco says. "My experiences there inspired me to pursue a career in science after graduation."
