Faculty and Staff

Lindsay Augustyn is the Outreach and Communications Director for the Center for Science, Mathematics and Computer Education, which assists with conference logistics. She oversees conferences and workshops, and focuses on graphic design, such as the creation of brochures, magazines and promotional materials for events. Her background is in newspaper design and editing, as well as the hospitality industry. She graduated from UNL with a Bachelor of Journalism and a Master of Arts in journalism. This is her eighth year on the committee.


Dr. Huijing Du is a new assistant professor in UNL Department of Mathematics. She got her Ph.D. in the area of Applied and Computational Mathematics from University of Notre Dame, and then she was a Postdoctoral Scholar at University of California, Irvine. Her work is in the area of computational and mathematical biology. This is her first year serving on the NCUWM organizing committee.


Dr. Glenn Ledder has been on the NCUWM Organizing Committee since 2005 and is currently the chair. His research area is mathematical modeling in the physical and biological sciences, and he is also a national leader in efforts to develop undergraduate mathematics curricula for biology students. He has mentored a total of 35 undergraduate research students, including REU Site student groups in the summers of 2002, 2003, 2006, 2010, and 2014.


Dr. Mohammad Rammaha is in his third year on the NCUWM Organizing Committee, and has been a member of the UNL Department of Mathematics faculty since 1985. His research interests lie in applied mathematics and analysis; in particular he works with issues concerning nonlinear hyperbolic partial differential equations. He has advised six doctoral students since arriving at Nebraska, and currently he is advising two doctoral students. In 2003 he received the College Distinguished Teaching Award from UNL and has also received the Recognition Award for Contribution to Students from the UNL Parents Association 11 times.


Stephanie Vendetti is the Events Coordinator for the Center for Science, Mathematics and Computer Education. She coordinates conferences, workshops, camps and other projects throughout the year administered by the CSMCE. Stephanie received her BFA from the University of South Carolina and MFA from RIT. Stephanie enjoys organizing and facilitating events that make an impact; this is her fifth year on the committee.


Dr. Alex Zupan is an assistant professor at UNL in his second year on the NCUWM Organizing Committee. His research is in geometry and topology. In particular, he studies 3- and 4-dimensional manifolds and the theory of knots in these dimensions. He earned his Ph.D. from the University of Iowa and spent three years as an NSF Postdoc at the University of Texas at Austin, where he supervised an undergraduate research project.

Graduate Students

Jessica DeSilva is a fourth year graduate student studying combinatorics under Dr. Jamie Radcliffe. She is an NSF Graduate Research Fellow and a Graduate Student Ambassador for UNL Graduate Studies. In her spare time, Jessica enjoys working out at the UNL recreation center and trying out new restaurants around Lincoln. This is her second year on the NCUWM organizing committee.


Nathan Poppelreiter is a fourth year graduate student at UNL studying math ecology under Richard Rebarber and Brigitte Tenhumberg, where he works to apply Kalman filters to ecological questions. Before he found mathematics, he attended Western Culinary Institute in Portland, Oregon. Outside of school, he enjoys cooking, playing boardgames, and writing and running a pen-and-paper roleplaying game. This is his first year on the NCUWM organizing committee.


Stephanie Prahl is currently a fourth year graduate student studying operator algebras under Dr. David Pitts. She graduated in 2013 from the University of Wisconsin-Eau Claire with a double major in mathematics and English literature. She spends most of her free time reading, cooking, biking, and knitting. This is her first year on the NCUWM organizing committee.


Ariel Setniker is currently a fourth year graduate student studying fractional calculus under Dr. Allan Peterson. On top of her research, Ariel enjoys investigating mathematics curriculum and lesson planning, while also exploring industry with an internship at a software incubator company. As a former resident of the west coast, she enjoys everything outdoors, gardening and cooking. This is her second year serving on the NCUWM organizing committee.


Katie Tucker is a third year graduate student studying topology under Dr. Mark Brittenham and Dr. Susan Hermiller. A West Coast-er at heart, she graduated from Willamette University in Oregon. In her spare time she knits, bakes cookies and bread, grows large amounts of basil, and makes more pesto than her freezer can hold.
